Econ 2030- Test 1 I. What Economics Is economics : the study of how human beings coordinate their wants and desires, given the decision-making mechanisms, social customs, and political realities of the society. Key words: coordination 3 central problems facing any economy: 2. How to produce it. 3. For whom to produce it for Problem of scarcity : goods available are too few to satisfy individuals’ desires. 2 elements of scarcity : our wants and our means of fulfilling those wants Quantity of goods, services, and usable resources depends on technology and human action, which underlie production. Economy deals with scarcity by coercion . Coordination involved some type of coercion- limiting the wants of people and increasing the amount of work people want to do. II. A Guide to Economic Reasoning Think like an economist: address almost all issues using a cost/benefit approach Focus on important questions and create a simple model, then collect empirical evidence and “test” the model to see if it fits. Economic Reasoning : how to think like an economist, making decisions on the basis of costs and benefits. Provides a framework within which to approach a question. People do what is in their best interest financially – rely on cost/benefit analysis to make decisions III. Marginal Costs and Marginal Benefits Relevant costs and relevant benefits: expected incremental or additional costs incurred and the expected incremental benefits that result from a decision. Marginal cost : additional cost to you over and above the costs you have already incurred. Sunk Costs : costs that have already been incurred and cannot be recovered. Marginal benefit : additional benefit above what you’ve already derived. - ex: m.b. of this chapter is additional knowledge you get from reading it, if you already knew everything in the book- the marg. ben. would be zero.
