Chapter 1: The Market




The first chapter introduces you to the basic idea of a market. A market is a place where buyers (consumers) meet sellers (producers) to exchange goods or services. A market can be physical (such as a supermarket) or virtual (such as an online platform). A market can be local (such as a farmers' market) or global (such as Amazon).


The main function of a market is to determine prices (how much buyers pay) and quantities (how much sellers produce) for each good or service. Prices and quantities depend on two key factors: demand (how much buyers want) and supply (how much sellers offer). Demand reflects buyers' preferences (what they like), income (how much they can afford), prices (how much they have to pay), expectations (what they think will happen in future), etc. Supply reflects sellers' costs (how much they have to spend), technology (how efficiently they can produce), prices (how much they can earn), expectations (what they think will happen in future), etc.


The chapter explains how demand curves (which show how much buyers want at different prices) slope downward (because buyers want more when prices are lower) while supply curves (which show how much sellers offer at different prices) slope upward (because sellers offer more when prices are higher). It also shows how demand curves shift when there is a change in any factor other than price that affects demand (such as income or preferences) while supply curves shift when there is a change in any factor other than price that affects supply (such as costs or technology).


and supply curves in a market. This point is called the market equilibrium, where the quantity demanded equals the quantity supplied. It also explains how market equilibrium changes when there is a shift in either demand or supply curves. This causes a change in prices and quantities, which can be analyzed using comparative statics (comparing the old and new equilibrium). It also illustrates how market equilibrium maximizes total surplus (the sum of consumer surplus and producer surplus), which is a measure of social welfare (how well off society is).


The chapter also introduces two important concepts that measure how responsive buyers and sellers are to changes in prices: elasticity and consumer surplus. Elasticity measures the percentage change in quantity demanded or supplied when there is a one percent change in price. It depends on how sensitive buyers or sellers are to price changes. Consumer surplus measures the difference between what buyers are willing to pay and what they actually pay for a good or service. It reflects how much benefit buyers get from buying a good or service.


Chapter 2: Budget Constraint




The second chapter introduces you to the concept of a budget constraint. A budget constraint is a line that shows all the possible combinations of two goods or services that a consumer can afford given his or her income and prices. It represents the consumer's choices or opportunities.


The chapter explains how the slope of the budget constraint equals the ratio of prices of the two goods or services. It also shows how the budget constraint shifts when there is a change in income or prices. It also illustrates how the budget constraint can be used to analyze consumer behavior under different scenarios such as income effect (how income changes affect consumption) and substitution effect (how relative price changes affect consumption).


The chapter also introduces another concept that shows how consumers rank different combinations of goods or services according to their preferences: indifference curves. Indifference curves are curves that show all the combinations of two goods or services that give the consumer the same level of satisfaction or utility. They represent the consumer's tastes or preferences.


The chapter explains how indifference curves are downward sloping (because consumers prefer more of both goods or services) and convex (because consumers prefer balanced bundles over extreme bundles). It also shows how indifference curves differ depending on the type of preferences: perfect substitutes (when consumers are indifferent between two goods or services), perfect complements (when consumers always consume two goods or services in fixed proportions), normal goods (when consumers prefer more of a good or service as their income increases), inferior goods (when consumers prefer less of a good or service as their income increases), etc.


The chapter also shows how the optimal choice for a consumer is determined by the tangency point between the budget constraint and the highest possible indifference curve. This point is called the consumer's optimum, where the marginal rate of substitution (the slope of the indifference curve) equals the price ratio (the slope of the budget constraint). It also explains how the optimal choice changes when there is a change in income or prices, using income and substitution effects.


Chapter 3: Preferences




The third chapter delves deeper into the concept of preferences. Preferences are subjective judgments that consumers make about how much they like different combinations of goods or services. Preferences are based on personal values, beliefs, experiences, emotions, etc.


The chapter explains how preferences can be represented by utility functions, which assign numerical values to different combinations of goods or services based on how much satisfaction they give to consumers. Utility functions are ordinal (they only show rankings, not magnitudes) and unique up to monotonic transformations (they can be changed by any increasing function without affecting rankings).


The chapter also explains how preferences have some basic properties that make them consistent and rational: completeness (consumers can compare any two combinations of goods or services), transitivity (if consumers prefer A to B and B to C, then they prefer A to C), non-satiation (consumers always prefer more of at least one good or service), continuity (small changes in combinations do not cause big changes in preferences), convexity (consumers prefer averages over extremes), monotonicity (consumers prefer more of both goods or services).


The chapter also gives some examples of different types of preferences that violate some of these properties: lexicographic preferences (when consumers rank goods or services based on one attribute only), satiated preferences (when consumers have enough of both goods or services), discontinuous preferences (when small changes in combinations cause big changes in preferences), non-convex preferences (when consumers prefer extremes over averages), non-monotonic preferences (when consumers prefer less of both goods or services).


The chapter also introduces another concept that shows how consumers can infer their preferences from their choices: revealed preferences. Revealed preferences are preferences that are consistent with observed choices. They can be used to test whether consumers behave rationally and whether utility functions exist.


Chapter 4: Utility




The fourth chapter explores further the concept of utility. Utility is a numerical measure of satisfaction that consumers get from consuming different combinations of goods or services. Utility is based on preferences, but it also depends on constraints such as income and prices.


The chapter explains how utility can be measured by cardinal utility functions, which assign numerical values to different combinations of goods or services based on how much satisfaction they give to consumers. Cardinal utility functions are interval (they show magnitudes, not just rankings) and unique up to positive linear transformations (they can be changed by any positive constant or coefficient without affecting magnitudes).


The chapter also explains how utility can be measured by ordinal utility functions, which assign numerical values to different combinations of goods or services based on their rankings according to preferences. Ordinal utility functions are ordinal (they only show rankings, not magnitudes) and unique up to monotonic transformations (they can be changed by any increasing function without affecting rankings).


The chapter also introduces two important concepts that measure how utility changes when there is a change in consumption: marginal utility and diminishing marginal utility. Marginal utility is the change in total utility when there is a one unit change in consumption of one good or service, holding everything else constant. Diminishing marginal utility is the property that marginal utility decreases as consumption increases, holding everything else constant.


The chapter also shows how marginal utility and diminishing marginal utility explain some key phenomena in consumer behavior such as the law of demand (the inverse relationship between price and quantity demanded), income effect (the change in consumption due to a change in real income), substitution effect (the change in consumption due to a change in relative prices), Giffen goods (goods whose demand increases when their price increases), Veblen goods (goods whose demand increases because their price increases).


(cost of producing one more unit of output), and sunk cost (cost that cannot be recovered or avoided).


The chapter also shows how cost curves are derived from production functions and isoquants, using the concepts of marginal product and diminishing marginal product. It also shows how cost curves change when there is a change in prices of inputs or technology, using the concepts of scale effect (the change in cost due to a change in output) and substitution effect (the change in cost due to a change in input mix).


The chapter also gives some applications of cost theory to production decisions such as long-run versus short-run decisions (when some inputs are fixed and some are variable), economies of scale (when average cost decreases as output increases), diseconomies of scale (when average cost increases as output increases), economies of scope (when it is cheaper to produce two goods together than separately), and learning curve (when average cost decreases as cumulative output increases).


Chapter 8: Profit Maximization




The eighth chapter introduces you to the concept of profit maximization. Profit maximization is a goal or a criterion that producers use to decide how much output to produce and how much inputs to use. Profit is the difference between revenue (the amount of money earned from selling output) and cost (the amount of money spent on producing output).


The chapter explains how profit can be measured by profit functions, which show the maximum amount of money that can be earned from producing a given amount of output, given the prices of inputs and outputs and the technology. Profit functions are interval (they show magnitudes, not just rankings) and unique up to positive linear transformations (they can be changed by any positive constant or coefficient without affecting magnitudes).


The chapter also explains how profit maximization can be achieved by choosing the output level that equates marginal revenue (the change in total revenue when there is a one unit change in output) and marginal cost (the change in total cost when there is a one unit change in output). This condition ensures that producing one more unit of output does not increase or decrease profit.


The chapter also shows how profit maximization can be achieved by choosing the input mix that equates marginal rate of technical substitution (the slope of the isoquant) and price ratio (the slope of the budget constraint). This condition ensures that using one more unit of one input and one less unit of another input does not increase or decrease profit.


The chapter also gives some examples of profit maximization problems under different market structures such as monopoly (when there is only one producer in the market), oligopoly (when there are few producers in the market), monopolistic competition (when there are many producers in the market with differentiated products), and price discrimination (when producers charge different prices to different consumers based on their willingness to pay).


Chapter 9: Competitive Markets




The ninth chapter introduces you to the concept of competitive markets. Competitive markets are markets where there are many buyers and sellers, each with a small share of the market, who trade identical products at a common price. Competitive markets have some characteristics such as price taking behavior (buyers and sellers take the market price as given), free entry and exit (buyers and sellers can enter or exit the market without any barriers or costs), perfect information (buyers and sellers have full knowledge of prices, quantities, qualities, etc.), and zero economic profit (producers earn just enough to cover their costs).


The chapter explains how competitive markets can be analyzed using the concepts of market equilibrium, market demand, market supply, and market efficiency. Market equilibrium is the point where the quantity demanded equals the quantity supplied in a market. Market demand is the horizontal sum of individual demand curves in a market. Market supply is the horizontal sum of individual supply curves in a market. Market efficiency is the property that market equilibrium maximizes total surplus in a market.


The chapter also shows how competitive markets can be analyzed using the concepts of consumer surplus, producer surplus, deadweight loss, and social surplus. Consumer surplus is the difference between what buyers are willing to pay and what they actually pay for a good or service in a market. Producer surplus is the difference between what sellers are willing to accept and what they actually receive for a good or service in a market. Deadweight loss is the reduction in total surplus due to a distortion such as a tax or a subsidy in a market. Social surplus is the sum of consumer surplus and producer surplus minus deadweight loss in a market.


(when buyers or sellers change their behavior after entering the market).


Chapter 10: Market Power




The tenth chapter introduces you to the concept of market power. Market power is the ability of a producer to influence the price or quantity of a good or service in a market. Market power arises from sources such as barriers to entry (factors that prevent new entrants from competing in a market), product differentiation (factors that make products different from each other), network effects (factors that make products more valuable as more people use them), and strategic behavior (actions that affect the choices of other producers).


The chapter explains how market power can be measured by market concentration (the share of the market controlled by a few producers), price elasticity of demand (the responsiveness of quantity demanded to price changes), and Lerner index (the difference between price and marginal cost as a fraction of price).


The chapter also explains how market power can be exercised by setting prices above marginal cost, producing less than the efficient quantity, earning positive economic profit, and creating deadweight loss. It also shows how market power can be reduced by competition (from existing or potential rivals), regulation (by government agencies or laws), and antitrust policy (by government actions to prevent or break up monopolies or cartels).


The chapter also gives some examples of market power problems such as natural monopoly (when one producer can produce at a lower cost than many producers), regulation (when government sets prices or quantities for natural monopolies or public utilities), antitrust policy (when government intervenes in cases of monopoly, oligopoly, monopolistic competition, or cartel), and strategic behavior (when producers use actions such as price leadership, price wars, collusion, cooperation, signaling, commitment, threats, etc. to affect the choices of other producers).
