Chapters: 4
1. Exchange over time
Intertemporal exchange · Life course, pensions and public debt
- Interest Rates: Saving, Borrowing and Investment – An interest rate is the price of borrowing money, written as a percentage per year. Savers earn interest as a reward for waiting and for taking a risk; borrowers pay it. Rates depend on the central bank's base rate, on risk, on time and on collateral. Higher rates encourage saving and discourage borrowing, spending and investment.
- Pensions: Money for When You Stop Working – A pension is an income you get after you retire. In a pay-as-you-go (PAYG) system, today's workers pay for today's retirees. In a funded system, each person saves into a pot that is invested and grows with compound interest. Most countries mix three pillars: a state pension, a workplace pension and private savings. Because people live longer and have fewer children, there are fewer workers per retiree, which puts pressure on PAYG systems and on public debt. Starting to save early is the strongest single lever.
2. Cooperation and bargaining
Game theory · Suboptimal outcomes
- Game Theory: Making the Best Choice When Others Choose Too – Game theory studies decisions where your result depends on what others choose. A pay-off matrix lists each player's gain for every pair of choices. A dominated strategy is always worse and can be removed. A Nash equilibrium is a pair of choices where no player gains by changing alone; the prisoner's dilemma shows it can be worse for everyone than cooperating. In a zero-sum game, the play-safe (maximin/minimax) strategies meet at a saddle point when the game is stable; otherwise players use a mixed strategy, found by drawing expected-pay-off lines and taking the highest point of the lower edge.
- Market Failure – A market fails when buying and selling on its own does not give the best result for society. Resources are used in the wrong amounts: too much of some goods (pollution, cigarettes), too little of others (street lights, vaccines, education). Main causes: externalities, public goods, merit and demerit goods, imperfect information, market power and unfair inequality. Governments try to fix it with taxes, subsidies, rules, direct provision and information, but government action can also fail.
3. Risk and information
Risk · Asymmetric information · Asymmetric information in firms · Insuring risk · Investing
- Insurance: Principles and Types – Insurance spreads the loss of a few over many people who each pay a small premium into a common pool. It works on six principles: utmost good faith, insurable interest, indemnity, contribution, subrogation and causa proxima (plus mitigation of loss). The main types are life, health, fire and marine insurance.
- Asymmetric Information: When One Side Knows More – Information is asymmetric when one side of a deal knows more than the other. A used-car seller knows the car's faults, the buyer does not. A person who buys insurance knows more about their own habits than the insurer. Getting information costs money and time (transaction costs), so some of it stays hidden. Hidden information before a deal causes adverse selection: the buyer can only offer an average price, good sellers leave, and the market fills with bad quality. Hidden action after a deal causes moral hazard: once someone else bears the cost, a person takes less care. The same problem appears inside firms as the principal-agent problem, where an owner (principal) cannot watch what a manager or worker (agent) really does, and in finance, where lenders cannot see how risky a borrower is. Remedies are better information (inspection, reports, ratings), signals (warranty, certificates, reputation), screening, collateral, contracts that share the risk (an excess or deductible), incentive pay and supervision.
- Financial Markets – A financial market links people who save with businesses that need money. The money market deals in short-term funds (up to one year) through call money, treasury bills, commercial paper, certificates of deposit and commercial bills. The capital market deals in long-term funds and has a primary market (new issues) and a secondary market (stock exchange, old securities). Shares are held in demat form with a depository (NSDL, CDSL), and SEBI protects investors, develops and regulates the market.
4. Research, experiments and electives
Research and economic experiments · Elective topics (at least two)
- Research Skills: From a Question to a Finished Project – Research is a careful way of finding an answer. You ask a clear, focused question, plan how to answer it, find information and check that each source can be trusted, collect and analyse your own data, draw a conclusion that the evidence supports, and share it while crediting every source you used.
- Economics Basics: How People, Firms and the State Choose – Economics is the science of how people, firms and governments use limited resources to meet unlimited wants. Needs are met by goods and services (free vs economic goods, consumer vs capital goods, private vs public goods). Because of scarcity, every society answers What, How and For whom to produce. Three economic agents act: households (work, consume, save), firms (produce and sell to earn profit = revenue − cost) and the state (rules, taxes, public services). Economics uses methods like observation, models and statistics; it splits into microeconomics (one household, firm, market) and macroeconomics (whole economy: GDP, unemployment, inflation, cycles). Social goals include growth, full employment, stable prices, fair income sharing and sustainability.
