Chapter 1 Economics: Foundations and Models Scarcity – our resources are limited while wants are not Economics – the study of the choices consumers, business managers, and government officials make to attain their goals given their scarce resources Economic models – simplified versions of reality used to analyze real-world economic situations 1.1 Three Key Economic Ideas Market – a group of buyers and sellers of goods/services and the institution by which they come together to trade 1. People are rational.  We make decisions based on the information available to us.  The outcome may turn out unexpectedly, but that does not make it an irrational decision. 2. People respond to economic incentives.  Incentives are intended either to move people away from purchases or to draw more people into purchases.  Example 1: higher taxes on cigarettes are intended to decrease purchases.  Example 2: by reducing costs of obesity, health insurance may give people an economic incentive to gain weight 3. Optimal decisions are made at the margin.  Economists reasons that activity should continue until marginal benefits equal marginal costs (MB = MC)  Marginal analysis – analysis that involves comparing marginal benefits and marginal costs  Economic reasoning – making decisions on the basis of costs and benefits o There are usually monetary and opportunity costs vs. benefits o Example: It costs money to attend class, and time spent travelling to and attending class takes away from time that could be spent doing something possibly more productive. These are costs.  Costs and benefits are subjective!! 1.2 The Problem That Every Society Must Face  Trade off – the idea that because of scarcity, producing more of one good or service means producing less of another good or service; trade-offs are made when answering the following questions: 1. What goods and services will be produced? 2. How will the goods and services be produced? 3. Who will receive the goods and services produced?  Opportunity cost – highest-valued alternative that must be given up to engage in an activity o Monetary & time costs o Choosing the best option means sacrificing only your second best option—not all other possible activities! o Ranking your alternatives helps make a decision Centrally Planned vs. Market Economics  Centrally planned economy (pure command)– government decides how economic resources will be allocated o Full control of central planner o Common resources o What is produced? What the government deems necessary o How is it produced? Government determines capitol/labor intensity o Who gets output? Equal distribution, “to each according to their need” o Ex) Cambodia, China, Cuba, North Korea o (Ideal) motivation:  Communal good  Market economy (pure market)– decisions of households and firms interacting in markets allocate economic resources o No government intervention o Laissez-Faire o Allocation and choices left solely to market o Private resources o Determined by Market Price Mechanism (invisible hand) o Capitalism o Free markets o What is produced? What people are willing and able to buy o How is it produced? Efficiently & profit maximizing o Who gets output? Based on ability, effort, and inheritance/wealth o Motivation:  Self interest  Profit  Wealth  “Mixed” economy o Minimal government role in addition to interaction of buyers and sellers o Government plays significant role under certain circumstances Efficiency and Equity  Productive efficiency – good or service produced at lowest cost  Allocative efficiency – production is in accordance with consumer preferences; each good is produced until marginal cost outweighs benefit  Voluntary exchange – occurs in markets when both the buyer and seller are made better off by the transaction  Equity – fair distribution of economic benefits  Trade-off between efficiency and equity (often faced by government policymakers) 1.3 Economic Models Steps to develop a model: 1. Decide on behavioral assumptions 2. Formulate testable hypothesis 3. Use economic data to test hypothesis 4. Revise model 5. Answer future related questions with revised model The Role of Assumption  We reduce complexity to better analyze economic issues  Economists assume that consumers will buy goods and services that maximize their well-being or satisfaction Forming and Testing Hypotheses  Economic variable – something measurable that can have different values, such as incomes  Scientific method – the process of developing models, testing hypotheses, and revising models Normative and Positive Analysis  Positive analysis is concerned with what is  Normative analysis is concerned with what ought to be; cannot be proven or disproven  Economics is about positive analysis (measures costs vs. benefits) Economics as a Social Science  Studies human decision-making behavior in every context 1.4 Microeconomics and Macroeconomics  Microeconomics – the study of how households and firms make choices, how they interact in markets, and how the government attempts to influence their choices  Macroeconomics – the study of the economy as a whole, including topics such as inflation, unemployment, and economic growth A Preview of Important Economic Terms  Entrepreneurs operate businesses, decide what goods and services to produce and how, and risk their own funds to do so.  Invention is the development of a new good or process for making something, while innovation is the practical application of an invention.  Technology is the process a firm uses to produce goods and services; depends on skill of managers, training of workers, and the speed and efficiency of equipment.  Firm, company, or business are used interchangeably to mean and organization that produces a good or service.  Goods are tangible merchandise.  Services are activities done for others.  Revenue is the total amount received for selling a good or service o Price per unit multiplied by number of units sold  Profit is the difference between revenue and costs.  Households consist of all persons occupying a home; suppliers of factors of production used by firms and governments  Factors of production or economic resources are labor, capital, natural resources (land), and entrepreneurial ability.  Financial capital includes stocks and bonds issued by firms, bank accounts, and holdings of money.  Physical capital includes manufactured goods that are used to produce other goods and services. * This is the type of capital referred to in economics. *  Human capital refers to the accumulated training and skills that workers possess.
