2 The Economic Problem Basic economic problem wants are virtually unlimited While the resources available to satisfy these wants are scarce Resource are scarce when they are not freely available Economics examines the issue of how people use their scarce resources in an attempt to satisfy their unlimited wants

3 Resources Inputs, or factors of production, used to produce the goods and services Thus, goods and services are scarce because resources are scarce Four general categories Labor Capital Land Entrepreneurial Ability

4 Labor Broad category of human effort – physical and mental Labor is scarce because the time that can be allocated to various tasks is scarce or limited

5 Capital Human creations used to produce goods and services Physical capital: factories, machines, tools, buildings, airports, highways and other manufactured items employed to produce goods and services Human capital: consists of the knowledge and skill people acquire to enhance their labor productivity

6 Land &Entrepreneurial Ability Land Includes not only land in the conventional sense but also all other natural resources Gifts of nature including bodies of water, trees, oil reserves, etc. Entrepreneurial Ability Special kind of human skill Talent required to dream up a new product or find a better way to produce an existing one

7 Goods and Services Resources can be combined in a variety of ways to produce goods and services Goods Tangible items Require scarce resources Satisfy human wants Services Intangible items Require scarce resources Satisfy human wants

8 Markets Means by which buyers and sellers carry out exchanges Bring together the two sides of exchange to determine price and quantity by providing information about the quantity, quality, and price of products offered for sale Product markets Markets in which goods and services are bought and sold Resource Markets Markets in which the resources are exchanged Labor, or job, market is the most important of the resource markets

9 Households supply resources in the resource market and demand goods and services in the product market Firms supply goods and services in product market and demand resources in the resource market Money flows in resource market determine wages, interest, rents, and profits which flow as income to households Product markets determine the prices for goods and services which flow as revenue to firms Exhibit 1: Circular-Flow Model

10 Micro and Macro economics Microeconomics Examines the factors that influence individual economic choices Examines how markets coordinate the choices of various decision-makers Studies the individual pieces of the economic puzzle Macroeconomics Studies the performance of the economy as a whole Focuses on the big picture

11 Pitfalls of Economic Analysis Fallacy that Association is Causation Occurs when one assumes that event A caused event B simply because the two are associated in time The fact that one event precedes another or that the two events occur simultaneously does not necessarily mean that one event caused the other Fallacy of Composition Erroneous belief that what is true for the individual or the part, is also true for the group, or the whole

12 Ignoring Secondary Effects Unintended consequences of policies or choices Primary Effects Effects that are felt relatively quickly Easily observed Secondary Effects Tend to develop more slowly Frequently not obvious
