## 经济代写|行为金融学代写Behavioral Finance代考|Simple heuristics for complex choices

Even the most innocuous of economic choices are in principle very complicated. For example, consider a shopper in a grocery store looking at rows of breakfast cereal and deciding which one to buy. Should she buy the cereal she usually buys? Should she try a new cereal the store has just introduced? Should she buy the cereal on special offer? Will the cereal she usually buys be on special offer next week? Will it be cheaper in another store? Should she be tempted by the cereal with the chance to win a holiday in the Caribbean?

Clearly, most of us do not spend much time considering all these issues. Indeed, most of us simply buy the cereal that we usually buy. That way we can make a quick decision that will probably keep us happy. This is an example of a heuristic.A heuristic is any ‘rule of thumb’ or simple rule of behavior by which a person solves a problem. The shopper can solve their problem of what cereal to buy with the heuristic ‘Buy what I usually do’. Almost all the economic decisions we make are based on such heuristics; otherwise, life would get far too complicated. This makes it important for us to know how heuristics work and what their consequences can be.

Heuristics, and the biases they give rise to, are going to be a recurring theme throughout the book, and are the primary focus of this chapter. I will start by giving some examples, but the main thing I want to do is provide some structure for how to think about the consequences of heuristics. In doing this we shall come across some of the key concepts and ideas in behavioral economics.

If Anna does not know the quality of goods, or her utility function, then she can gather more information in order to become better informed; we call this search.A search heuristic specifies what Anna should do in order to become better informed. There are lots of possible search heuristics, and I shall look at five to give you some idea of what they, and heuristics in general, look like.

The most obvious search heuristic is ‘Try everything’. For example, Anna could try a different cereal every week until she has tried them all, and then subsequently buy the one she liked the most. This means she will end up knowing a lot about cereals. Potentially, however, the process will be costly. To see why, suppose that in the first week she tries Honey and can tell that she likes it a lot. If she sticks to her heuristic then in subsequent weeks she will have to buy and try cereals that are not going to give her as much utility. She would have been better off just sticking with Honey (if you will excuse the pun).

In this case, search proves costly in terms of forgone utility. Search can also be costly in terms of time and money. A good search heuristic needs to trade off the benefits of acquiring more information with these costs. Characterizing optimal, or good, search algorithms has a long history in mathematics, computer science and economics. Optimal search algorithms are typically very complicated, however, so we need to think what search heuristics people could realistically use that come close to the optimum. Three such heuristics are satisficing, elimination by aspects and directed cognition.
