| Consumer choice theory analyzes how individuals make decisions to allocate their limited resources among various goods and services. | | | | 3 | What is the concept of 'substitutes' in economics? | Substitutes are goods that can replace each other; an increase in the price of one leads to an increase in demand for the other. | | | | 4 | What is the role of incentives in economic decision-making? | Incentives motivate individuals and firms to act in certain ways, influencing their choices and behaviors. | | | | 5 | What is the role of government in correcting market failures? | The government can intervene through regulations, taxes, subsidies, or provision of public goods to correct market failures. | | | | 6 | Define producer surplus. | Producer surplus is the difference between the amount producers are willing to accept for a good and the actual price they receive. | | | | 7 | What is a monopoly? | A monopoly is a market structure where a single seller dominates the market, leading to reduced competition. | | | | 8 | Define the term 'marginal cost.' | Marginal cost is the additional cost incurred from producing one more unit of a good or service. | | | | 9 | What is the role of information asymmetry in markets? | Information asymmetry occurs when one party has more or better information than the other, leading to market failures. | | | | 10 | What is the principle of diminishing marginal returns? | The principle of diminishing marginal returns states that as more of a variable input is added to a fixed input, the additional output produced will eventually decrease. | | | | 11 | How do constraints affect individual economic decisions? | Constraints, such as income and prices, limit the choices available to individuals, influencing their consumption and production decisions. | | | | 12 | Define public goods. | Public goods are goods that are non-excludable and non-rivalrous, meaning they are available to all without diminishing availability. | | | | 13 | What is the significance of the indifference curve? | Indifference curves represent combinations of goods that provide the same level of utility to a consumer, illustrating preferences. | | | | 14 | Explain the concept of market failure. | Market failure occurs when the allocation of goods and services is not efficient, often due to externalities, public goods, or information asymmetry. | | | | 15 | What is the Nash equilibrium? | Nash equilibrium is a situation in a game where no player can benefit by changing their strategy while others keep theirs unchanged. | | | | 16 | What is the role of expectations in economic decision-making? | Expectations influence consumer and producer behavior, as individuals make decisions based on anticipated future conditions. | | | | 17 | How do firms determine their optimal level of production? | Firms determine their optimal level of production by equating marginal cost with marginal revenue. | | | | 18 | Define utility in the context of microfoundations. | Utility is a measure of satisfaction or happiness that a consumer derives from consuming goods and services. | | | | 19 | Explain the concept of elasticity in microeconomics. | Elasticity measures how responsive the quantity demanded or supplied is to changes in price or other factors. | | | | 20 | What is the significance of the law of demand? | The law of demand states that, all else being equal, as the price of a good decreases, the quantity demanded increases, and vice versa. | | | | 21 | What is the significance of the production possibilities frontier (PPF)? | The PPF illustrates the trade-offs between two goods, showing the maximum possible output combinations given resources. | | | | 22 | Define the term 'game theory' in economics. | Game theory studies strategic interactions among individuals or firms, where the outcome depends on the choices of all participants. | | | | 23 | Explain the concept of a budget line. | A budget line represents all possible combinations of two goods that a consumer can purchase with a given income at current prices. | | | | 24 | Why are microfoundations important in economics? | Microfoundations are important because they provide a more detailed understanding of how individual behaviors aggregate to influence overall economic outcomes. | | | | 25 | How does behavioral economics differ from traditional economics? | Behavioral economics incorporates psychological insights into economic decision-making, challenging the assumption of rationality. | | | | 26 | What is a production function? | A production function describes the relationship between inputs used in production and the resulting output. | | | | 27 | What is the difference between microeconomics and macroeconomics? | Microeconomics focuses on individual agents and markets, while macroeconomics examines the economy as a whole, including aggregate indicators like GDP and inflation. | | | | 28 | Explain the concept of price discrimination. | Price discrimination occurs when a seller charges different prices to different consumers for the same good, based on willingness to pay. | | | | 29 | What is consumer surplus? | Consumer surplus is the difference between what consumers are willing to pay for a good and what they actually pay. | | | | 30 | What is the concept of rational choice theory? | Rational choice theory posits that individuals make decisions by maximizing their utility based on their preferences and constraints. | | | | 31 | What are the characteristics of perfect competition? | Perfect competition features many buyers and sellers, homogeneous products, free entry and exit, and perfect information. | | | | 32 | What is the difference between short-run and long-run in economics? | In the short run, at least one input is fixed, while in the long run, all inputs can be varied. | | | | 33 | What are externalities in economics? | Externalities are costs or benefits of economic activities that affect third parties not involved in the transaction. | | | | 34 | Explain the concept of market equilibrium. | Market equilibrium occurs when the quantity demanded equals the quantity supplied at a particular price. | | | | 35 | Define marginal utility. | Marginal utility is the additional satisfaction gained from consuming one more unit of a good or service. | | | | 36 | What role do preferences play in microfoundations? | Preferences represent the individual tastes and choices that drive consumer behavior and decision-making in economic models. | | | | 37 | What is the difference between fixed costs and variable costs? | Fixed costs do not change with the level of output, while variable costs fluctuate with production levels. | | | | 38 | What is the concept of 'marginal revenue'? | Marginal revenue is the additional income gained from selling one more unit of a good or service. | | | | 39 | What is the significance of the law of supply? | The law of supply states that, all else being equal, as the price of a good increases, the quantity supplied also increases. | | | | 40 | What is the concept of opportunity cost? | Opportunity cost is the value of the next best alternative foregone when making a decision. | | | | 41 | What is the concept of diminishing marginal utility? | Diminishing marginal utility states that as a person consumes more of a good, the additional satisfaction gained from each unit decreases. | | | | 42 | What is the role of competition in microeconomic markets? | Competition drives efficiency, innovation, and lower prices, benefiting consumers and the economy as a whole. | | | | 43 | Explain the concept of the budget constraint. | The budget constraint represents the combinations of goods and services that a consumer can purchase given their income and prices. | | | | 44 | What is the significance of the concept of 'scarcity' in economics? | Scarcity refers to the limited nature of society's resources, necessitating trade-offs and choices in allocation. | | | | 45 | Define 'economic efficiency.' | Economic efficiency occurs when resources are allocated in a way that maximizes total surplus, including both consumer and producer surplus. | | | | 46 | Define 'inelastic demand.' | Inelastic demand refers to a situation where the quantity demanded changes little in response to price changes. | | | | 47 | What are economic microfoundations? | Economic microfoundations refer to the individual-level behaviors and decisions that underpin macroeconomic theories and aggregate economic phenomena. | | | --- Study this deck interactively with FSRS-6 spaced repetition, audio review, and multiple-choice mode at [Flashcards World](https://flashcards.world/flashcards/sets/a1540c9b-270f-41dd-8dba-bd1fe23d6a82/).
