This paper examines Mark Blaug's position on the normative character of Paretian welfare economics: in general, and specifically with respect to his debate with Pieter Hennipman over this question during the 1990s. The paper also clarifies some of the confusions that emerged within the context...

The death of welfare economics has been declared several times. One of the reasons cited for these plural obituaries is that Kenneth Arrow's impossibility theorem, as set out in his path-breaking Social Choice and Individual Values in 1951, has shown that the social welfare function - one of the...

In recent years the term behavioral economics has arisen in consequence of the growing effort of a significant set of economists to import psychological methods and findings into economics. This body of work issues strong challenges to the use economists have made of rationality in economics....

I examine the circumstances under which a sophisticated time-inconsistent decisionmaker (i) will not or (ii) need not severely miscoordinate her behavior across time, in the sense of following a course of action which fails to be Pareto-optimal for the sequence of temporal selves of the...

Nudges, which are interventions that do not restrict choice, have become widespread in policy applications. I develop a general and tractable framework to analyze the welfare implications of nudges. In this framework, individuals suffer from internalities (their utility when choosing is...

In this paper, we study methods of inferring a decision maker's true preference relation when observed choice data reveal a nontransitive preference relation due to choice mistakes. We propose some sensible properties of such methods and show that these properties characterize a unique rule of...

When an individual's preferences depend on the time or 'frame' at which decisions are made, the preferences that appear at different frames must be aggregated in order to make social decisions. Suppose we aggregate each individual i's frame-based preferences with a 'behavioral welfare relation'...

We present a method for evaluating the welfare of a decision maker, based on observed choice data. Unlike the standard economic theory of revealed preference, our method can be used whether or not the observed choices are rational. Paralleling the standard theory we present a model for choice...

We extend the swaps index of rationality, introduced by Apesteguia and Ballester (2015) for a finite set of alternatives, to the standard consumer choice setting with infinite commodity spaces. Applications include consumer demand from competitive budget sets and the state-space approach to...
