The elegant economic picture of rational consumers achieving Pareto optimality through trade in decentralized self-organized markets is blurred by market imperfections and choices inconsistent with consumer self-interest. Behavioral economics has documented these errors in choice, and considered...

Does mental accounting matter for total consumption expenditures? We exploit a unique setting in which individuals exogenously received a new credit card, without requesting one. Using random variation in the time of receipt we show that individuals temporarily increase total consumption...

We document two new facts about the distributions of answers in famous statistical problems: they are i) multi-modal and ii) unstable with respect to irrelevant changes in the problem. We offer a model in which, when solving a problem, people represent each hypothesis by attending "bottom up" to...

This article reviews the growing economics literature that studies the politico-economic impacts of heterogeneity in moral boundaries across individuals and cultures. The so-called universalism-versus-particularism cleavage has emerged as a main organizing principle behind various salient...

This article calls for a greater integration of moral psychology and political economy. While these disciplines were initially deeply intertwined, cross-disciplinary exchange became rare throughout the 20th century. More recently, the tide has shifted again - social scientists of different...

We propose a framework where perceptions of uncertainty are driven by the interaction between cognitive constraints and the way that people learn about it--whether information is presented sequentially or simultaneously. People can learn about uncertainty by observing the distribution of...

Choosing what is morally right can be based on the consequences (ends) resulting from the decision - the Consequentialist view - or on the conformity of the means involved with some overarching notion of duty - the Deontological view. Using a series of experiments, we investigate the overall...

How quickly does marginal utility fall with increasing consumption? It depends on the dimension along which we consider concavity of the utility function. This paper estimates the distribution of heterogeneous curvature parameters in individuals' utility functions from hypothetical choice data,...

We estimate the effects of large, positive wealth shocks on marriage and fertility in a sample of Swedish lottery players. For male winners, wealth increases marriage formation and reduces divorce risk, suggesting wealth increases men's attractiveness as prospective and current partners. Wealth...
