1.1.1 What is a Business?
A business is an organised effort by individuals or groups to produce and sell goods or services to meet a market need, typically with the aim of generating a profit and creating value for stakeholders.
In today's world, businesses do not operate in isolation. They exist within a complex environment shaped by digital economies, evolving customer expectations, competitive markets, and ever-changing government regulations. In Sri Lanka, this complexity is amplified by new sustainability standards (SLFRS S1 and S2) and economic shifts following recent financial pressures.
The Four Core Purposes of a Business
- Profit Generation: Profit is the financial return earned after all costs are covered. It is not just a reward for owners — it funds future investment, research, expansion, and provides a buffer against economic downturns. Without sustained profit, a business cannot survive long-term.
- Value Creation: Businesses create value by producing goods and services that customers willingly pay for. Value creation goes beyond the price tag — it includes quality, reliability, convenience, and customer experience. A business that consistently creates superior value builds loyalty and a strong market position.
- Employment: By hiring people, businesses provide livelihoods, support families, and contribute to economic stability. In Sri Lanka, SMEs are particularly vital as engines of employment across diverse sectors including agriculture, garments, tourism, and IT.
- Societal Contribution: Businesses contribute to society through tax payments that fund public services, through responsible environmental practices, and through community investment. Increasingly, companies are expected to act as responsible "corporate citizens," going beyond legal compliance to actively benefit society.
Small and Medium-sized Enterprises (SMEs) form the backbone of Sri Lanka's economy, yet they face unique pressures: limited access to capital, skill gaps in digital and sustainability literacy, and the cost burden of new compliance requirements. The introduction of SLFRS S1 (general sustainability disclosures) and SLFRS S2 (climate-related disclosures) now requires even smaller listed entities to report on ESG factors — transforming sustainability from a "nice to have" into a core business function.
1.1.2 Stakeholder Identification & Analysis
A stakeholder is any individual, group, or organisation that is affected by — or has the ability to affect — the activities and outcomes of a business.
Stakeholders are typically categorised as internal (those within the organisation) or external (those outside it). Understanding and managing stakeholder relationships is one of the most critical skills for any business leader.
Internal Stakeholders
- Shareholders / Owners: Provide capital and take on financial risk. They expect financial returns (dividends and capital appreciation) and have voting power over major business decisions. Their interests must be balanced against ESG compliance costs — a tension that is increasingly visible in Sri Lanka's listed companies.
- Employees: Contribute labour, skills, creativity and institutional knowledge. They expect fair wages, job security, safe working conditions, career development, and to be treated with dignity. In knowledge-intensive industries (technology, finance), talent retention is a critical competitive factor.
- Management: Responsible for day-to-day decision-making and strategic direction. Their interests include job security, remuneration, and the ability to implement their vision effectively.
External Stakeholders
- Customers: Purchase goods and services, providing the revenue stream that keeps the business alive. They expect quality, fair pricing, honesty, and ethical production. In an age of social media, reputational damage from dissatisfied customers spreads quickly and can be devastating.
- Suppliers: Provide raw materials, components, or services. They want prompt payment, fair contract terms, and a stable long-term relationship. Strong supplier relationships are critical for supply chain resilience — especially for Sri Lankan exporters dependent on imported inputs.
- Creditors / Banks: Provide debt financing and expect timely repayment of principal and interest. Their relationship with the business is sensitive to Central Bank policies affecting interest rates and credit availability.
- Government & Regulators: Set the legal framework within which businesses operate. They expect tax compliance, adherence to labour laws, environmental regulations, and consumer protection standards. Bodies like the Colombo Stock Exchange (CSE) and CA Sri Lanka shape governance and financial reporting standards.
- Community & Society: Provide the "social licence to operate" — the informal but vital permission from society for a business to exist and grow. Communities expect environmental stewardship, local employment, and responsible corporate citizenship.
| Stakeholder | Primary Interest | Potential Conflict With | Key Metric |
|---|---|---|---|
| Shareholders | Profit, dividends, share value | Employees (wages), Community (costs) | EPS, ROE, Share price |
| Employees | Wages, security, conditions | Shareholders (cost reduction) | Staff turnover, satisfaction scores |
| Customers | Quality, price, reliability | Shareholders (margin pressure) | Customer satisfaction, NPS |
| Suppliers | Payment, contracts, partnership | Management (cost cutting) | Payment days, contract renewal rate |
| Government | Tax, compliance, stability | Shareholders (tax burden) | Tax paid, compliance audits |
| Community | Environment, employment, CSR | Shareholders (cost of ESG) | Carbon footprint, local jobs created |
A garment factory in Sri Lanka wants to cut costs by reducing wages (shareholder interest). But this conflicts with employees' right to fair pay, may violate minimum wage laws (government interest), and could lead to poor product quality affecting customers. The factory also risks protests from community groups and losing its "social licence to operate."
A sustainable solution might involve investing in automation (increasing efficiency) to maintain margins while preserving jobs — satisfying multiple stakeholders simultaneously. This is the challenge of stakeholder management.

10 Questions1.2.1 Sole Proprietorship
A sole proprietorship is a business owned and operated by a single individual. The law treats the owner and the business as one and the same — there is no legal separation between personal and business affairs.
Key Features
- Ownership & Control: The proprietor has complete control over all decisions. There are no partners or board members to consult, enabling fast, flexible decision-making.
- Liability: Unlimited personal liability — the owner's personal assets (home, savings, vehicle) are fully at risk if the business incurs debts or legal judgments.
- Capital: Limited to the owner's personal savings and any personal loans they can obtain. This restricts growth potential.
- Continuity: The business has no perpetual existence — it ceases upon the owner's death, incapacity, or decision to close.
- Taxation: Business income is treated as the owner's personal income and taxed under individual income tax rates. There is no separate corporate tax.
Sri Lankan Registration Requirements
A sole proprietorship in Sri Lanka is not a legally separate entity. If operating under any name other than the owner's personal name, it must register under the Business Names Ordinance No. 6 of 1918. This registration is relatively simple and inexpensive, making it the most accessible form of business.
- Simple and cheap to set up
- Full control by the owner
- All profits retained by owner
- Minimal regulatory burden
- Privacy — no public filing of accounts
- Unlimited personal liability
- Limited capital raising ability
- No continuity after death
- Entire burden on one person
- May struggle to compete with larger firms
1.2.2 Partnership
A partnership is a business structure where two or more individuals co-own and co-manage a business, sharing profits, losses, and management responsibilities according to a partnership agreement.
Key Features
- Ownership: Shared between partners as agreed in the partnership deed. Profits and losses are distributed according to the agreed profit-sharing ratio.
- Liability: Each partner typically carries unlimited joint and several liability — meaning any one partner can be held personally responsible for the full debts of the partnership, not just their share.
- Capital: Partners pool their personal resources, providing more capital than a sole proprietor but still limited compared to a company that can issue shares.
- Management: Shared decision-making can bring diverse expertise but also the potential for disputes and deadlocks.
- Continuity: The partnership may dissolve if a partner withdraws, dies, or becomes bankrupt, unless the partnership agreement provides for continuity.
Sri Lankan Regulatory Framework
Partnerships in Sri Lanka are governed by the Partnership Act of 1890. Key requirements:
- Minimum 2, maximum 50 partners
- No separate legal existence — the business and its partners are legally one
- Not subject to corporate income tax — income is allocated to individual partners per the profit-sharing ratio, and each partner pays personal income tax on their share
- No mandatory public filing of accounts, providing privacy
Many professional firms in Sri Lanka — law firms, accounting practices, medical clinics — operate as partnerships. Partners contribute specialist expertise, share the client base, and divide profits. However, if one partner commits professional misconduct leading to a large liability claim, all other partners may be personally exposed under joint and several liability. This is why professional firms increasingly consider incorporation.
1.2.3 Company (Limited Liability)
A company is a legal entity that is entirely separate from its owners (shareholders). It can own property, enter contracts, sue and be sued in its own name. Shareholders' liability is limited to the amount they invested.
Types of Companies in Sri Lanka (Under the Companies Act)
- Private Limited Company (Pvt Ltd): Shares cannot be offered to the public. Maximum shareholders is typically restricted. Most common for growing SMEs.
- Public Limited Company (PLC): Can raise capital by offering shares to the public through the Colombo Stock Exchange (CSE). Subject to more rigorous reporting and governance requirements.
- Unlimited Company: Shareholders have unlimited liability but the company is still a separate legal entity.
- Guarantee Company: Members guarantee to contribute a fixed amount if the company is wound up. Common for non-profit organisations.
Governance Requirements for Listed Companies
Public listed companies must comply with the Code of Best Practice on Corporate Governance (issued by CA Sri Lanka and the Securities and Exchange Commission). This covers:
- Board composition (mix of executive and independent non-executive directors)
- Audit committees and financial oversight
- Risk management frameworks
- Transparent disclosures to shareholders and the public
| Feature | Sole Proprietorship | Partnership | Company |
|---|---|---|---|
| Legal Status | No separate entity | No separate entity | Separate legal entity |
| Liability | Unlimited personal | Unlimited personal | Limited liability |
| Capital Access | Personal only | Pooled personal | Shares + debt markets |
| Compliance Burden | Minimal | Moderate | Extensive |
| Decision Making | Sole owner | Shared (partnership deed) | Board of directors |
| Taxation (SL) | Personal income tax | Allocated to partners | Corporate tax rate applies |
| Continuity | Ends with owner | May dissolve on changes | Perpetual existence |
| Suitable For | Solo entrepreneurs, small traders | Professional firms, small joint ventures | Growing businesses, public fundraising |

10 Questions1.3.1 Core Business Functions Explained
Accounting
Accounting is the systematic process of recording, classifying, summarising, and interpreting financial transactions. It is the "language of business" — converting all activity into a universal financial format. Key outputs include the income statement, balance sheet, and cash flow statement. Modern accounting also encompasses management accounting (internal decision support), cost accounting, and increasingly, sustainability reporting under SLFRS S1 and S2.
Finance
Finance is about managing money over time. The finance function is responsible for: capital budgeting (deciding which major investments to make), capital structure (determining the best mix of debt and equity), working capital management (ensuring daily operations have sufficient liquidity), and risk management (using financial instruments like hedging to protect against currency or interest rate volatility).
Marketing
Marketing is the process of identifying customer needs and creating, communicating, and delivering value to satisfy those needs profitably. It encompasses market research, segmentation, targeting, positioning, product development, pricing, promotion, and distribution. In a digital age, marketing increasingly relies on data analytics — using customer behaviour data to personalise campaigns and improve conversion rates.
Human Resources (HR)
HR manages the organisation's most valuable asset: its people. HR responsibilities span the full employee lifecycle: workforce planning, recruitment and selection, onboarding, training and development, performance management, compensation and benefits, and eventual offboarding. In Sri Lanka's competitive talent market (particularly in technology and financial services), HR strategy is a critical source of competitive advantage.
Operations
Operations manages the processes that transform inputs (raw materials, labour, information) into outputs (products or services). It encompasses quality control, process design, capacity planning, and continuous improvement (often using methodologies like Lean or Six Sigma). Efficiency in operations directly determines a business's cost structure and customer satisfaction levels.
Research & Development (R&D)
R&D drives long-term competitiveness by developing new products, services, and processes. It involves both basic research (exploring new knowledge) and applied research (turning knowledge into commercial products). R&D investment is a key determinant of a business's ability to innovate and remain relevant as markets and technologies evolve.
Supply Chain & Logistics
Supply Chain management covers the full network of activities required to deliver a product — from sourcing raw materials to delivering the finished product to the end customer. This includes supplier selection, procurement, inventory management, and vendor relationships. Logistics is the physical movement component: transportation, warehousing, and distribution. In Sri Lanka's export-oriented economy (garments, tea, spices), efficient supply chain and logistics are critical for international competitiveness.
Administration
Administration provides the organisational infrastructure that enables all other functions to operate. This includes facilities management, IT support, governance systems, policy development, document management, and regulatory compliance coordination. Without effective administration, even the most talented teams struggle to function efficiently.
1.3.2 How Functions Interact — Accounting's Central Role
Accounting acts as the "central nervous system" of the business — it receives information from all functions, processes it into financial data, and sends back insights that guide each function's decisions. Key accounting tools that support cross-functional decision-making include:
- Cost-Benefit Analysis: Used by Finance and Operations to evaluate investment decisions — should we buy new machinery? Open a new branch? The analysis compares expected future benefits against the full cost of the decision.
- Budgeting: The annual budget aligns all functions with company-wide financial goals. Marketing gets a promotional budget; HR gets a hiring budget; Operations gets a capital expenditure budget. Budgets force coordination and trade-off decisions.
- Variance Analysis: Compares actual financial results against the budget and investigates differences (variances). This is a key management tool for identifying where performance is above or below expectation.
- Financial Forecasting: Projects future revenues and costs based on assumptions about market conditions. Used by all functions to plan ahead — production plans production volumes, HR plans headcount, Finance plans capital needs.
| Function | Key Responsibilities | How Accounting Supports It |
|---|---|---|
| Finance | Capital management, investment analysis | Financial modelling, project appraisal (NPV/IRR), financial statements |
| Marketing | Customer acquisition, brand management | Customer profitability analysis, campaign ROI tracking, pricing models |
| HR | Talent management, payroll, culture | Payroll processing, cost-per-hire tracking, training cost analysis |
| Operations | Process efficiency, quality control | Cost of production reports, variance analysis, overhead allocation |
| Supply Chain | Procurement, vendor management | Inventory valuation, supplier cost analysis, stock-out cost modelling |
| R&D | Innovation, product development | R&D cost capitalisation/expensing decisions, project budget tracking |
When a Sri Lankan apparel company wants to launch a new sustainable fabric range:
- R&D develops the product and tests fabric quality
- Marketing conducts market research and designs the brand campaign
- Operations assesses production capacity and lead times
- Supply Chain sources new sustainable raw materials from certified suppliers
- Finance evaluates the investment required and projected returns
- Accounting builds the financial model, tracks all costs, and reports on profitability post-launch
- HR recruits and trains staff for the new production process
All functions must coordinate — and accounting provides the financial framework that keeps everyone aligned with the company's overall financial goals.

10 Questions1.4.1 The Three Dimensions of Value Creation
The traditional view of business success focused almost exclusively on financial returns to shareholders. Contemporary thinking — and increasingly, regulation — demands a broader view of value creation:
1. Economic Value
Creating economic prosperity for shareholders through profits, dividends, and share price appreciation. But also contributing to the wider economy through wages paid to employees, taxes contributed to government, and business given to suppliers. Economic value creation is still the foundation — a business that cannot sustain itself financially cannot create any other form of value.
2. Social Value
Improving quality of life and well-being for employees, communities, and society more broadly. This includes: providing safe, fair, and fulfilling employment; investing in community development; ensuring products and services genuinely improve customers' lives; and contributing to education, healthcare, or local infrastructure through CSR initiatives.
3. Environmental Value (Stewardship)
Protecting natural resources and ecosystems for future generations. This means reducing carbon emissions, minimising waste, adopting circular economy principles, sourcing materials responsibly, and avoiding environmental damage. In a world facing climate change, environmental stewardship is increasingly tied to long-term business viability — companies that damage the environment face growing regulatory, financial, and reputational risks.
A major Sri Lankan garment exporter creates economic value (profit for shareholders, wages for thousands of workers, export revenue for the country), social value (training programmes, health clinics, school scholarships for employees' children), and environmental value (water recycling systems, eco-friendly dyes, solar panels on factory roofs). This integrated approach is exactly what global buyers and investors increasingly demand — and what SLFRS S2 now requires companies to report on.
1.4.2 Ethical Responsibilities & ESG
Ethics in business means conducting operations in a manner that is morally right — going beyond simply following the law to actively doing what is good for all stakeholders. The three core ethical principles identified in the chapter are:
- Transparency: Being open and honest in all communications with stakeholders. This means publishing accurate financial reports, disclosing material risks and uncertainties, being clear about product ingredients and sourcing, and not misleading customers through advertising. Transparency builds trust — the foundation of all long-term business relationships.
- Accountability: Taking personal and organisational responsibility for actions and their consequences — even when those consequences are negative. An accountable business does not hide mistakes, deflect blame, or evade consequences. It acknowledges errors, compensates those harmed, and changes practices to prevent recurrence.
- Fairness: Treating all stakeholders equitably — paying workers a living wage, pricing products fairly, applying rules consistently, and not discriminating. Fairness means different stakeholders are not exploited for the benefit of others.
The ESG Framework
Environmental, Social, and Governance (ESG) is the formal framework through which businesses disclose their performance across these three dimensions:
- Environmental (E): Carbon emissions, energy usage, water consumption, waste management, biodiversity impact, supply chain environmental standards.
- Social (S): Employee health and safety, labour standards, diversity and inclusion, community relations, human rights in supply chains, product safety.
- Governance (G): Board composition, executive pay, shareholder rights, anti-corruption policies, audit quality, whistleblowing procedures, transparency of reporting.
The Social Licence to Operate
Beyond formal regulation, businesses need ongoing acceptance and approval from society to operate. This "social licence" is not a legal document — it is earned through consistent ethical behaviour and lost through misconduct, environmental damage, or exploitation. Once lost, a social licence is extremely difficult to rebuild. Companies like those in mining, heavy industry, and fast fashion have discovered that public protests, consumer boycotts, and reputational damage can be more commercially damaging than regulatory fines.
Studies show that companies with strong ESG ratings experience lower cost of capital (investors see them as lower risk), stronger talent attraction and retention, greater customer loyalty and willingness to pay premium prices, and fewer regulatory penalties and legal costs. Ethics is not just the right thing to do — it is increasingly a source of competitive advantage and long-term profitability.

10 Questions1.5.1 Emerging Technology Trends
Technology has moved from being a support function to being the core engine of business strategy. The key technologies reshaping business can be grouped into three pillars:
Pillar 1: Intelligent Automation & Decision-Making
- Artificial Intelligence (AI): AI systems can analyse vast datasets to identify patterns, make predictions, and recommend decisions — faster and often more accurately than humans. In business, AI is applied in credit scoring, fraud detection, demand forecasting, personalised marketing, and increasingly in sustainability compliance monitoring. A key challenge: 65% of Sri Lankan professionals need more training in AI tools — a significant skills gap.
- Machine Learning (ML): A subset of AI where systems learn and improve from experience without being explicitly programmed. ML models improve over time as they process more data, making them powerful for tasks like customer churn prediction, price optimisation, and predictive maintenance.
- Robotic Process Automation (RPA): Software "bots" that automate repetitive, rule-based tasks (data entry, invoice processing, report generation). RPA frees human employees from tedious work, allowing them to focus on higher-value analytical and creative tasks.
Pillar 2: Pervasive Connectivity & Data Infrastructure
- Cloud Computing: Delivers computing resources (processing power, storage, software) over the internet on a pay-per-use basis. The main benefit is cost efficiency — businesses access enterprise-grade tools without massive upfront hardware investment. Especially transformative for Sri Lankan SMEs who can now access cloud-based ERP, accounting, and CRM software that was previously only affordable for large corporations.
- Internet of Things (IoT): A network of physical devices — sensors, machines, vehicles — embedded with software that allows them to collect and exchange data in real time. In manufacturing, IoT sensors monitor machine performance and predict failures before they happen (predictive maintenance). In logistics, IoT enables real-time tracking of shipments. In retail, smart shelves automatically reorder stock when levels fall.
Pillar 3: Digital Trust & Security
- Blockchain: A decentralised, distributed digital ledger where transactions are recorded permanently and cannot be altered. Key applications: supply chain traceability (tracking a product from farm to store), smart contracts (self-executing contracts triggered when conditions are met), and transparent financial reporting. Blockchain increases trust by making information tamper-proof and independently verifiable.
- Cryptocurrency: Digital assets that use blockchain technology as a medium of exchange (e.g., Bitcoin, Ethereum). While adoption in commerce is still evolving, cryptocurrencies represent a new form of financial asset and payment mechanism that challenges traditional banking and monetary policy frameworks.
- Cybersecurity: As businesses digitise, protecting data and systems becomes critical. A cyberattack can halt operations, expose sensitive customer data, destroy reputation, and trigger regulatory penalties. Cybersecurity includes firewalls, encryption, identity management, incident response planning, and staff training. It is the essential foundation without which all other digital investment is at risk.
| Technology | Key Business Use | Primary Benefit | Sri Lankan Relevance |
|---|---|---|---|
| AI & ML | Predictive analytics, compliance monitoring | Better decisions, risk management | Needed for SLFRS S1/S2 compliance analysis |
| Cloud Computing | SaaS software, remote working | Cost efficiency, scalability | Critical enabler for SMEs |
| IoT | Supply chain tracking, predictive maintenance | Real-time operational visibility | Garment and manufacturing sectors |
| RPA | Data entry, reporting automation | Frees staff for strategic work | Financial services automation |
| Blockchain | Supply chain traceability, smart contracts | Trust, transparency, security | Agricultural export certification |
| Cybersecurity | Data protection, threat prevention | Business continuity, compliance | Essential for all digital operations |
1.5.2 Data Analytics & Business Intelligence
Data Analytics is the process of examining raw data to find patterns, draw conclusions, and support decision-making. Business Intelligence (BI) is the framework of technologies, processes, and practices used to deliver data insights to decision-makers in accessible formats (dashboards, reports, visualisations).
Data is now described as "the new oil" — a raw resource that, when refined through analytics, becomes enormously valuable. The shift is from intuition-based decisions to evidence-based decisions. The key types of analytics applied in business are:
- Descriptive Analytics: "What happened?" — summarises historical data to understand past performance. Standard financial reports and dashboards are examples.
- Diagnostic Analytics: "Why did it happen?" — investigates the cause of a trend or event. Example: Why did sales drop 15% in Q3?
- Predictive Analytics: "What will happen?" — uses statistical models and ML to forecast future outcomes. Example: Which customers are likely to churn next month?
- Prescriptive Analytics: "What should we do?" — recommends optimal actions based on predicted outcomes. The most advanced form of analytics.
Business Applications
- Financial Analytics: Improves performance measurement, risk assessment, fraud detection, and financial forecasting accuracy.
- Customer Analytics: Analyses purchasing behaviour, preferences, and sentiment to personalise offers and improve customer experience.
- Operational Analytics: Identifies inefficiencies in production or service delivery processes and drives continuous improvement.
- Supply Chain Analytics: Optimises inventory levels, identifies supply disruption risks, and improves logistics routing.

10 Questions2.1.1 Core Resource Concepts
Microeconomics is the branch of economics that addresses the problem of scarcity at the individual level — studying how individuals, households, and firms make decisions to allocate limited resources to satisfy their wants and needs.
Economic Resources (Factors of Production)
Economic resources are inputs used to produce goods and services. They are scarce — limited in supply relative to unlimited human wants. The four main types are:
- Land: All natural resources — soil, minerals, water, forests, oil. The return to land is called rent.
- Labour: Human effort — physical and mental — applied to production. The return to labour is wages/salaries.
- Capital: Manufactured resources used to produce other goods — machinery, buildings, equipment, technology. (Note: in economics, "capital" means physical productive assets, not just money.) The return to capital is interest.
- Entrepreneurship: The ability to organise the other factors, take risks, and innovate. The return to entrepreneurship is profit.
Scarcity, Choice, and Opportunity Cost
Scarcity is the fundamental economic problem: resources are finite but human wants are infinite. This forces every economic agent — individuals, businesses, governments — to make choices about how to allocate resources.
Every choice involves giving up alternatives. The opportunity cost of any decision is the net benefit of the best alternative that was foregone. This is one of the most important concepts in economics — it reminds us that the true cost of any decision is not just what you pay, but what you give up.
Business Example: A Sri Lankan tea company has Rs. 10 million. It can invest in upgrading its tea processing machinery (expected return: Rs. 2 million/year) OR in opening a new retail outlet (expected return: Rs. 1.5 million/year). If it chooses the machinery, the opportunity cost is the Rs. 1.5 million foregone from the retail outlet.
Personal Example: A student who spends 4 hours studying for an economics exam cannot use those hours working part-time (earning Rs. 2,000). The opportunity cost of studying is Rs. 2,000 of foregone wages — even though studying itself has no money cost.
Utility
Utility is the satisfaction or benefit a consumer derives from consuming a good or service. It is the reason people are willing to pay for things. Key insight: marginal utility (the satisfaction from one additional unit) typically diminishes as more is consumed — the first cup of tea is very satisfying; the fifth cup, less so. This principle of diminishing marginal utility helps explain downward-sloping demand curves.
2.1.2 Market Structures
A market structure describes the competitive environment in which firms operate. It is determined by: the number of firms, the nature of products (identical or differentiated), entry and exit barriers, and the level of market power held by individual firms.
| Feature | Perfect Competition | Monopoly | Oligopoly | Monopolistic Competition |
|---|---|---|---|---|
| Number of firms | Very many (infinite) | One | Few (3–10) | Many |
| Product type | Identical/homogeneous | Unique, no substitutes | Similar or differentiated | Differentiated |
| Market power | None — price takers | Strong — price maker | Significant but constrained | Limited, short-lived |
| Entry barriers | None (free entry/exit) | Very high | High | Low to moderate |
| Long-run profit | Normal profit only | Supernormal profit | Supernormal possible | Normal profit only |
| Example (SL) | Agricultural produce markets | Electricity distribution | Telecom sector (Dialog, Mobitel, Hutch) | Restaurants, clothing boutiques |

10 Questions2.2.1 The Laws of Demand and Supply
The Law of Demand
There is an inverse relationship between price and quantity demanded, all else equal (ceteris paribus). As price rises, quantity demanded falls; as price falls, quantity demanded rises. This produces a downward-sloping demand curve.
Why does this happen? Two reasons: (1) Substitution effect — as a product becomes more expensive, consumers switch to cheaper alternatives. (2) Income effect — as price rises, consumers' real purchasing power falls, so they buy less.
Non-price factors that SHIFT the demand curve (change demand at every price level):
- Consumer income — higher income generally increases demand for normal goods
- Prices of related goods — price of substitutes and complements
- Consumer tastes and preferences
- Future price expectations — if consumers expect prices to rise, they buy more now
- Population size and demographics
The Law of Supply
There is a direct relationship between price and quantity supplied, ceteris paribus. As price rises, quantity supplied rises; as price falls, quantity supplied falls. This produces an upward-sloping supply curve.
Why? Higher prices make production more profitable, incentivising existing suppliers to produce more and attracting new producers into the market.
Non-price factors that SHIFT the supply curve:
- Cost of production inputs (labour, materials, energy)
- Technology improvements — reduce costs, increase supply
- Number of suppliers in the market
- Government taxes (reduce supply) or subsidies (increase supply)
- Natural factors (weather, for agricultural goods)
2.2.2 Market Equilibrium & Disequilibrium
The state where quantity demanded equals quantity supplied at a specific price. This equilibrium price (also called the "market-clearing price") is where the market settles — there is no pressure for price to change.
- Surplus (Excess Supply): When price is above equilibrium → Qs > Qd → sellers cannot sell all their stock → prices fall → market moves back to equilibrium.
- Shortage (Excess Demand): When price is below equilibrium → Qd > Qs → buyers cannot get all they want → prices are bid up → market moves back to equilibrium.
Price Controls
- Price Ceiling (Maximum Price): Set BELOW equilibrium to keep prices affordable. Effect: permanent shortage. Over time, reduces investment in supply and quality. Examples: rent control, food price caps during shortages.
- Price Floor (Minimum Price): Set ABOVE equilibrium to protect producers/workers. Effect: permanent surplus. Examples: minimum wage (creates unemployment surplus), agricultural price supports.
Taxes and Subsidies
- Tax on producers: Shifts supply curve LEFT (reduces supply at every price), raising the equilibrium price and reducing equilibrium quantity. The tax burden is shared between producers (receive less) and consumers (pay more). The split depends on elasticity — the more inelastic side bears more of the burden.
- Subsidy to producers: Shifts supply curve RIGHT (increases supply at every price), lowering equilibrium price and increasing equilibrium quantity. Used to encourage production of goods with positive externalities (e.g., renewable energy).
2.2.3 Elasticity — Measuring Market Responsiveness
Elasticity measures the responsiveness (sensitivity) of one economic variable to a change in another. It is expressed as a ratio of percentage changes.
Price Elasticity of Demand (PED)
PED = % change in Quantity Demanded ÷ % change in Price
| PED Value | Classification | Meaning | Revenue Effect of Price Rise |
|---|---|---|---|
| PED > 1 | Elastic | Quantity changes more than price | Revenue FALLS |
| PED = 1 | Unit elastic | Quantity changes proportionally | Revenue UNCHANGED |
| PED < 1 | Inelastic | Quantity changes less than price | Revenue RISES |
| PED = 0 | Perfectly inelastic | Quantity unchanged regardless of price | Revenue rises proportionally |
Factors affecting PED: Availability of substitutes (more substitutes = more elastic), necessity vs luxury (necessities more inelastic), proportion of income spent (higher share = more elastic), time period (more elastic in the long run as consumers find alternatives).
Cross-Price Elasticity (CPED)
CPED = % change in Qd of Good A ÷ % change in Price of Good B
- Positive CPED: Goods A and B are substitutes (e.g., Coca-Cola and Pepsi — if Coke price rises, demand for Pepsi rises)
- Negative CPED: Goods A and B are complements (e.g., petrol and large cars — if petrol price rises, demand for large cars falls)
- Zero CPED: Goods are unrelated
Income Elasticity (YED)
YED = % change in Quantity Demanded ÷ % change in Income
- YED > 0 (Normal good): Demand increases as income rises. If YED > 1, it is a luxury good (demand rises faster than income).
- YED < 0 (Inferior good): Demand DECREASES as income rises (consumers switch to better alternatives). Example: instant noodles, public bus transport.
A Sri Lankan coconut oil producer raises price from Rs. 500 to Rs. 550 (a 10% increase). Sales fall from 10,000 bottles to 8,000 bottles per month (a 20% decrease).
PED = 20% ÷ 10% = 2.0 (Elastic)
Since PED > 1, the price increase REDUCES total revenue: before = Rs. 500 × 10,000 = Rs. 5,000,000; after = Rs. 550 × 8,000 = Rs. 4,400,000. The producer should consider cutting price to boost sales volume and total revenue instead.

10 Questions2.3.1 Monetary Policy
Monetary policy refers to actions taken by the Central Bank (in Sri Lanka: the Central Bank of Sri Lanka, CBSL) to manage the money supply and interest rates in order to achieve macroeconomic objectives such as price stability, economic growth, and financial system stability.
Key Monetary Policy Tools
- Policy Interest Rates (Standing Lending/Deposit Facilities): The benchmark rates CBSL sets for overnight lending to and borrowing from commercial banks. When CBSL raises rates, borrowing becomes more expensive throughout the economy — mortgages, business loans, and consumer credit all cost more. This slows spending and investment, reducing inflationary pressure.
- Open Market Operations (OMOs): CBSL buys or sells government securities (treasury bills/bonds) in the open market. Buying securities injects money into the banking system (increases liquidity, lowers rates). Selling securities withdraws money (decreases liquidity, raises rates).
- Repo & Reverse Repo Rates: The repo rate is the rate at which CBSL lends short-term funds to commercial banks (against government securities as collateral). The reverse repo rate is the rate CBSL pays when banks park excess funds with it overnight. These rates guide short-term market interest rates.
- Reserve Requirements: The minimum percentage of deposits that commercial banks must hold in reserve (not lend out). Raising reserve requirements reduces the amount banks can lend, tightening credit. Reducing requirements increases lending capacity.
- Quantitative Easing (QE): Large-scale purchases of government bonds by the central bank to inject liquidity when conventional rate cuts are insufficient (typically at zero lower bound). QE lowers long-term interest rates and stimulates investment.
- Forward Guidance: Communication by the CBSL about its future policy intentions. By clearly signalling future rate paths, the central bank influences expectations and reduces uncertainty — allowing businesses to make longer-term investment plans with greater confidence.
- Exchange Rate Interventions: CBSL buys or sells foreign currency (using its foreign reserves) to influence the rupee's exchange rate. Buying foreign currency weakens the rupee; selling foreign currency strengthens it.
| Monetary Condition | Financing Strategy | Investment Approach |
|---|---|---|
| Rising interest rates | Prioritise equity; repay debt; lock in fixed rates | Delay large projects; focus on quick-payback investments |
| Falling interest rates | Refinance at lower rates; consider more borrowing | Bring forward expansion; invest in long-term growth & R&D |
| Credit tightening | Secure credit lines early; manage working capital carefully | Focus on efficiency; postpone non-critical expansions |
2.3.2 Fiscal Policy
Fiscal policy refers to the government's use of spending, taxation, and borrowing to influence economic activity, redistribute income, and achieve macroeconomic objectives.
Key Fiscal Policy Tools
- Government Spending: Direct expenditure on infrastructure, public services, education, healthcare, and defence. Infrastructure spending creates demand for construction companies and suppliers; it also reduces business costs long-term through better transport networks and utilities.
- Taxation: Corporate income tax, personal income tax, VAT, customs duties, and excise taxes. Tax policy directly affects profit margins, consumer spending power, and investment incentives. Sri Lanka's revenue-to-GDP ratio nearly doubled from 8.3% to 13.7% between 2021–2024 due to significant tax reform.
- Subsidies and Grants: Direct financial support to encourage specific activities — renewable energy adoption, export promotion, R&D investment, or support for strategic industries. Subsidies lower costs for recipients and can stimulate innovation.
- Tax Incentives and Credits: Deductions or credits tied to specific behaviours (investing in R&D, creating jobs in priority zones, adopting green technology). These can significantly improve after-tax investment returns and attract foreign direct investment.
- Budget Management: Whether the government runs a deficit (spending > revenue), surplus (revenue > spending), or balanced budget signals economic confidence and future policy direction. Persistent deficits may require future tax increases or raise inflation expectations.
- Automatic Stabilisers: Progressive taxes and unemployment benefits that automatically adjust with the economic cycle — reducing taxes and increasing benefits during recessions (cushioning the downturn), and vice versa in booms.
Following the 2022 economic crisis, Sri Lanka undertook major fiscal consolidation — raising VAT from 8% to 18%, broadening the tax base, and cutting subsidies. For businesses, this meant higher compliance costs, reduced consumer spending power, and squeezed profit margins. Companies that had robust financial modelling and tax planning capabilities were better positioned to navigate these changes than those caught off-guard.
2.3.3 Exchange Rate Policy
Exchange rate policy governs how a country's currency is valued relative to other currencies. It affects the cost of imports and exports, foreign investment attractiveness, and the management of currency risk.
Exchange Rate Systems
- Fixed Exchange Rate: Currency is pegged to another currency (e.g., the US dollar) at a set rate. Provides stability and predictability for international trade. Risk: if the peg is unsustainable, it can result in a sudden, sharp devaluation.
- Floating Exchange Rate: Currency value is determined entirely by market forces (supply and demand for the currency). Naturally adjusts to economic conditions. Disadvantage: can be highly volatile, creating uncertainty for businesses.
- Managed Float (Sri Lanka's system): A hybrid — primarily market-determined but the CBSL intervenes when necessary to prevent excessive volatility or achieve policy objectives. Provides a balance between flexibility and stability but creates uncertainty about when and how the CBSL will intervene.
- Exchange Rate Bands: Currency is allowed to fluctuate within a specified upper and lower limit around a central rate. Provides some flexibility while containing volatility.
Three Types of Currency Risk for Businesses
- Transaction Risk: The risk that exchange rates change between agreeing on a price and settling payment. Example: an exporter agrees to receive USD 100,000 in 90 days, but the dollar weakens before payment arrives. Managed using forward contracts, currency options, or natural hedging.
- Translation Risk: An accounting risk from consolidating the financials of foreign subsidiaries (denominated in foreign currencies) into the parent company's home currency. Exchange rate movements can make reported profits appear better or worse than underlying performance.
- Economic Risk: The long-term risk that sustained currency movements affect a company's competitive position. A permanently strong rupee makes Sri Lankan exports more expensive abroad, potentially losing market share to competitors in other countries.

10 Questions2.4.1 Growth Indicators
Gross Domestic Product (GDP)
GDP is the total monetary value of all final goods and services produced within a country's borders in a given period. It is the most widely used measure of economic size and growth.
GDP can be measured three ways: (1) Expenditure approach — GDP = C + I + G + (X - M) where C=consumption, I=investment, G=government spending, X=exports, M=imports. (2) Income approach — sum of all incomes earned. (3) Output/Production approach — sum of value added at each stage of production.
Business implications: Rising GDP signals expanding markets, growing consumer spending, and positive investment conditions. Falling GDP (recession) warns of declining demand, potential credit tightening, and rising unemployment. For 78% of Sri Lankan firms planning to invest more, GDP growth trends are a primary decision input.
Gross National Income (GNI) & Per Capita Income
GNI measures the income earned by a country's residents (including from overseas), rather than just production within borders. Per Capita Income (GNI or GDP divided by population) measures average income per person — a key indicator of consumer purchasing power and market attractiveness for premium products.
2.4.2 Inflation Indicators
Consumer Price Index (CPI)
The CPI tracks price changes for a fixed basket of goods and services typically purchased by households. It is the primary measure of consumer inflation.
Rising CPI means consumers' cost of living is increasing. Businesses must monitor CPI for: wage negotiation benchmarks (employees expect wage rises to match inflation), pricing strategy (can we pass cost increases on to customers?), and contractual indexation (some long-term contracts include CPI adjustment clauses).
Producer Price Index (PPI)
The PPI measures price changes received by domestic producers for their output — essentially tracking input costs at the production level. Rising PPI is an early warning of future CPI increases (costs eventually pass through to consumers). For manufacturers, a rising PPI that cannot be passed on squeezes profit margins.
A Sri Lankan food processor sees PPI rising 12% due to rising energy and packaging costs. It can: (1) raise prices — acceptable if demand is inelastic; risky if competition is intense; (2) absorb costs — reduces margins, unsustainable long-term; (3) hedge input costs — using commodity futures to lock in current prices for future inputs; (4) improve efficiency — invest in automation to offset cost increases. The CPI data helps them understand whether customers are also experiencing rising living costs (which affects whether they'll accept a price increase).
2.4.3 Labour Market, Trade & Financial Indicators
Labour Market Indicators
- Unemployment Rate: % of the labour force actively seeking but unable to find employment. High unemployment = slack labour market → easier to recruit, lower wage pressure. Low unemployment = tight labour market → harder to recruit, higher wages, higher staff turnover risk. Source: Sri Lanka Department of Census and Statistics.
- Labour Force Participation Rate: % of working-age population (15-64) either employed or actively seeking work. A falling participation rate can mask unemployment — people may stop looking (discouraged workers) without showing up in the unemployment rate. Important for understanding the true scale of the available workforce.
- Wage Growth: Rate at which average wages are rising. If wage growth exceeds productivity growth, businesses face rising unit labour costs, squeezing margins.
Balance of Trade
The Balance of Trade = Exports − Imports. A surplus (positive) means the country earns more from exports than it spends on imports — supports currency strength. A deficit (negative) means more is imported than exported — creates downward pressure on the currency. Sri Lanka has historically run trade deficits, contributing to rupee depreciation and rising import costs — a key challenge for import-dependent businesses.
Stock Market Indices (e.g., ASPI — All Share Price Index, CSE)
The ASPI measures the average price performance of all shares listed on the Colombo Stock Exchange. Rising stock markets signal investor confidence, improving business valuations, and easier equity fundraising. Falling markets may signal economic concerns and make equity financing more expensive or difficult.
| Indicator | What Rising Figures Signal | Business Action |
|---|---|---|
| GDP Growth ↑ | Expanding economy, rising demand | Invest, expand, enter new markets |
| CPI (Inflation) ↑ | Rising consumer prices, cost of living up | Review pricing, renegotiate wages, hedge inputs |
| PPI ↑ | Rising input costs for producers | Manage costs, improve efficiency, negotiate with suppliers |
| Unemployment ↓ | Tight labour market, wages rising | Focus on retention, raise pay to compete for talent |
| Trade Deficit ↑ | Currency depreciation pressure | Hedge currency exposure, diversify away from import dependency |
| ASPI ↑ | Investor confidence, cheap equity | Consider equity fundraising, signal health to stakeholders |
| Consumer Confidence ↓ | Expected demand slowdown | Reduce inventory, delay investment, launch promotions |
2.4.4 Using Indicators for Strategic Decision-Making
The real value of macroeconomic indicators is not in passively observing them — it is in building them into a systematic strategic intelligence framework. The three-phase approach:
- Data Integration: Systematically collect and centralise key macroeconomic data from authoritative sources (CBSL, Department of Census and Statistics, CSE, IMF). Use automated data feeds and BI dashboards for real-time monitoring.
- Analysis & Forecasting: Interpret trends, identify correlations (e.g., how does CPI historically affect consumer spending in our sector?), and build predictive models to project future conditions. Use regression modelling and time-series analysis.
- Strategic Decision-Making: Translate insights into concrete decisions: adjust capital expenditure timing based on interest rate outlook; revise pricing strategy based on CPI and competitor responses; adjust headcount plans based on labour market tightness; hedge currency based on BOP trends.
