Introduction: Thinking Like an Economist CHAPTER 2 CHAPTER 23 Microeconomic Policy, Economic Reasoning, and Beyond If an economist becomes certain of the solution of any problem, he can be equally certain that his solution is wrong — H.

minimum wage is an example • If firms replace workers with machines in one industry, employment in the machine industry might rise 237 Microeconomic Policy, Economic Reasoning, and Beyond 23 The Cost/Benefit Approach in Context Ø Ø Cost/benefit analysis is an application of the supply/demand model • The supply curve represents marginal costs • The demand curve represents marginal benefits Equilibrium of demand and supply in competitive markets achieves economic efficiency • Economic efficiency - achieving a goal; in this case, producing a specified amount of output, at the lowest possible cost 238 Microeconomic Policy, Economic Reasoning, and Beyond 23 Failure of Market Outcomes Ø Ø Failure of market outcomes occurs when, even though the market is functioning properly (there are no market failures), the market is not achieving society’s goals Three types of market failure: • Failures due to distributional issues • Failures due to rationality problems of individuals • Failures due to violations of inalienable or at least partially inalienable rights of individuals 239 Microeconomic Policy, Economic Reasoning, and Beyond 23 Failure of Market Outcomes Distribution Issues Ø The market doesn’t necessarily distribute consumer surplus as we’d like it to: • • Ø The U.S has luxury goods but not enough health care for the poor In some African countries, almost 30% of the population has AIDS, but most don’t have the money to get the necessary drugs The sole purpose of society is not necessarily to maximize consumer and producer surplus; societies integrate other goals into the market 2310 Microeconomic Policy, Economic Reasoning, and Beyond 23 Failure of Market Outcomes Consumer Sovereignty and Rationality Problems Ø Ø Ø Ø The supply/demand framework assumes individuals are rational, that what individuals is in their own best interest Rationality failure of individuals is that sometimes we are irrational and things that aren’t good for us Governments can intervene to get people to what’s good for them Governments levy sin taxes, which are taxes that discourage activities society believes are harmful (sinful) 2311 Microeconomic Policy, Economic Reasoning, and Beyond 23 Government Failure Ø Ø Ø Failure of market outcomes does not necessarily call for government action For the government to correct a problem, it must: • Recognize the problem • Have the will to something positive about the problem • Have the ability to something positive about the problem Government seldom can all three of these well 2312 Microeconomic Policy, Economic Reasoning, and Beyond 23 Government Failure Response By Public Choice Economists Ø Ø Ø Public choice economists point out that politicians are subject to the laws of supply and demand Politicians’ goal is to provide a policy that their voting constituency likes • This can result in larger and larger government Public choice economists advocate as little government intervention as possible, even in the cases of market failures or failures of market outcomes 2313 Microeconomic Policy, Economic Reasoning, and Beyond 23 Chapter Summary Ø Ø Ø Ø Economists’ views differ because of different underlying value judgments, because empirical evidence is subject to different interpretations, and because their underlying models differ Economists tend to agree on certain issues because their training is similar; they use models that focus on economic incentives and rationality The economic approach to analyzing issues is a cost/benefit approach The cost/benefit approach and the supply/demand framework deemphasize the possibility that market outcomes may be undesirable to society 2314 Microeconomic Policy, Economic Reasoning, and Beyond 23 Chapter Summary Ø Ø Ø Three failures of market outcomes are failures due to (1) distributional issues, (2) rationality problems of individuals, and (3) violations of inalienable rights Society does care about how total surplus is distributed The supply/demand framework assumes that individuals are rational, but individuals are not always rational in practice Ø Inalienable rights cannot be bought or sold Ø Economics provides the tools, not the rules, for society 2315 ... applied to politicians 23 5 Microeconomic Policy, Economic Reasoning, and Beyond 23 Economists’ Cost/Benefit Approach to Government Regulation The cost/benefit approach to problems - assigning costs...
