The evidence shows that in many important economic domains, many people are either predisposed to engage in 'socially responsible actions' and/or required by regulations to do so. Examples include pollution abatement activity, behavior in a commons, and contributions to charity. We propose a...

We consider discounted-utility models with a reference stream of outcomes. We provide a common framework for the main empirically supported discount functions in terms of three underlying functions: The delay, speedup and generating functions. Each of the delay and speedup functions can be...

We explore the relation between social political identity and prosociality. We first construct a theoretical model to generate predictions for the behavior of players in an ultimatum game who are influenced by social political identity. Then we use a novel subject pool-registered members of...

We examine the various senses in which economist use the term “rationality” and then outline some of the commonly drawn implications and auxiliary assumptions. Finally, we confront the implications with the empirical evidence, drawing on the insights from the exciting new field of behavioral...

We formulate a general theory of preferences over outcome-time-probability triplets and decompose uncertainty into risk and hazard. We define the delay, defer, shift and certainty functions that can be uniquely elicited from behaviour. These individually determine stationarity, the common...

In a recent, 58 page, paper, Hashimzade, Myles and Tran-Nam (2009) "New Approaches to the Economics of Tax Evasion" survey alternative approaches to tax evasion. Their central conclusion is, in their own words (p. 56): "What they [the non-expected utility models] do not do is change the...
