Economic Behavior and Rationality Answer Key

ECONOMIC BEHAVIOR AND RATIONALITY Answers to Active Review Questions 1. 2. 3. 4. 5. 6. 7. 8. 9. neoclassical behavioral framing time discount rate satisfice path dependent bounded altrusitic False. Economics is a “social” science. It is not a pure science since the economy is far more difficult to analyze using the traditional scientific method than controlled laboratory experiments. 10. False. These are very different; in fact, weaknesses in neoclassical economics with regard to how people make decisions are what have given rise to behavioral economics. 11. False. It is known as framing. 12. True. 13. True. 14. True. 15. False. Meliorating is continuously attempting to improve upon one’s situation. 16. False. According to neoclassical economics, people only pursue self-interest, never altruism. 17. No, he did not. He believed that people often were motivated by self-respect, and having the respect of others. 18. Neoclassical economics narrowly holds that all economic decisions are dictated by rationality, which is the pursuit of self-interest. Behavioral economics offers a more nuanced approach to economic decision making, which maintains that rationality in a neoclassical sense is practically impossible (given existing real-world constraints) and that people are sometimes altruistic instead of self-interested. 19. Discuss in what way rationality is related to self-interest. Are the two concepts synonymous? According to the neoclassical model, the two are indistinguishable, since rationality is defined as the incessant pursuit of self-interest. The broader behavioral model, however, believes that rationality neither requires nor is required by self-interest. It allows for bounded rationality or satisficing (which it deems rational), as for altruistic behavior. Moreover, according to this model, self-interest can also be pursued irrationally. 20. One example is where we allow ourselves to be confused by the framing of a problem requiring a decision. “Lives saved” and “deaths averted” mean the same thing, but which is used often influences the choices people make. Another example is where we allow, say, one video transmission influence our thinking to a greater extent than a summary of many responses that contradicts the video. Such behavior is “irrational” according to the neoclassical model, but it is actuality quite common and not irrational according to the behavioral model. 21. No, it generally is not, nor should it be. For example, we tend to value the future to a significant degree when it comes to our finances, meaning that many save a fair share of their income for future use. On the other hand, many of us tend to be more shortsighted when it comes to making decisions (often related to consumption of products, energy, or materials) that have an adverse impact on the natural environment. For a variety of reasons, we tend to prefer pushing these “costs” on to future generations. 22. It is not necessarily inefficient to rely on our emotions; in fact, the opposite might be the case. For especially complicated economic decisions, it is almost impossible to obtain enough information that could be relevant to our ultimate choice. So wasting too much time gathering enough information might end up being inefficient in such situations (hence irrational), and it often is more efficient to rely on our intuition or emotions by “satisficing.” 23. The QWERTY arrangement of keys on a keyboard is a classic example. It was initially developed in order to slow down professional secretaries, since their extreme typing speed with more efficient arrangements would invariably lead the typewriter keys to become tangled and stuck. Of course this has not mattered for at least a few decades, but the less efficient system stuck. Another example might be where a concentration of businesses in a particular geographical area might ultimately lead to disproportionate economic development, where buyers cluster around the initial sellers, attracting more businesses to the area, etc. It may not be the most efficient geographical distribution of businesses, but it follows logically from its starting point. 24. A more broad-based definition would involve goals that are well-being enhancing but also that pursuit of the goals themselves contributes to well-being. More important, naked self-interest is not required. Altruism might often also contribute to well-being by, for example, strengthening the local community. Finally, a more broad-based definition would presume – more realistically than the neoclassical model – that it is often not possible to be rational (even though people mostly try to act rationally) on account of lack of relevant information in making decisions.

The deliberate changing of the presentation of choices in order to influence the final economic decision is known as _________________. 4. We say that people with a low _______________ place relatively high value on possible outcomes in the distant future. 5. People that ________________ generally do so because they possess insufficient information with which to make optimal decisions. 6.

We are being ________________________ if our actions are focused on the wellbeing of others instead of our own well-being. True or false 9. Economics is a “pure” science. 10. The neoclassical model of human behavior is consistent with the behavioral economics approach. 11. The deliberate change in the way in which available information is presented is known as the availability heuristic. 12. When we place less economic importance on the future than on the present, we are engaging in discounting. 13. It is possible to think about a choice among alternatives to an inefficiently excessive degree. 14. Satisficing is a better strategy than optimizing when the decision to be made is highly complex. 15. Meliorating refers to the act of engaging in bounded rationality. 16. According to neoclassical economics, people combine self-interest with altruism in pursuit of their economic goals. Short answer 17.
