We conduct two experimental tests of the claim that people are overconfident, using new tests of overplacement that are based on a formal Bayesian model. Our two experiments, on easy quizzes, find that people overplace themselves. More precisely, we find apparently overconfident data that cannot...

Numerous experiments have demonstrated the possibility of attitude polarization. For instance, Lord, Ross & Lepper (1979) partitioned subjects into two groups, according to whether or not they believed the death penalty had a deterrent effect, and presented them with a set of studies on the...

Some insurance markets are characterized by “advantageous selection,” that is, ex-post risk and coverage are negatively correlated. We show that expectation-based loss aversion as in K'oszegi and Rabin (2006, 2007) provides a natural explanation for this phenomenon when agents face modest...

We study optimal dynamic selling mechanisms in a two-stage model where the buyer can search for a better price at the second stage. When this outside price is public, the optimal selling mechanism takes the form of a fixed first-stage price with price matching in the second stage. In contrast,...

This paper lays a foundation for a new theory of manipulation, based on the misprioritization of (truthful) information. Since consumers review only a subset of all available information, firms can harm consumers by prioritizing information that maximizes firms’ profits but has a smaller...

Markets for consumer financial services are growing rapidly in low and middle income countries and being transformed by digital technologies and platforms. With growth and change come concerns about protecting consumers from firm exploitation due to imperfect information and contracting as well...

This chapter first describes the standard economic analysis of privacy, data protection and surveillance, looking at the costs and benefits to different parties and the incentives each therefore has, as well as the aggregate social welfare impacts of their decisions. It then considers the market...

We conduct a proper test of the claim that people are overconfident, in the sense that they believe that they are better than others. The results of the experiment we present do not allow us to reject the hypotheses that the data has been generated by perfectly rational, unbiased, and...
