Inherent in the definition of Pareto efficiency is the idea that, in dynamic environments, an individual is indexed by the history of events up to his birth (rather than, as usual, the date of birth). Here, we explore the implications of this natural formulation. The set of Pareto efficient...

A prominent assumption in modern optimal tax research is that the objective of taxation is Utilitarian. I present new survey evidence that most people reject this assumptionʼs implications for several prominent features of tax policy, instead preferring tax policies based at least in part on a...

Cognitive Economics is the economics of what is in people’s minds. It is a vibrant area of research (much of it within Behavioral Economics, Labor Economics and the Economics of Education) that brings into play novel types of data—especially novel types of survey data. Such data highlight...

This paper develops a tractable method for resolving the equity-efficiency tradeoff that modifies the Kaldor-Hicks compensation principle to account for the distortionary cost of redistribution. Weighting measures of individual surplus by the inequality deflator corresponds to searching for...

This paper illustrates how one can use causal effects of a policy change to measure its welfare impact without decomposing them into income and substitution effects. Often, a single causal effect suffices: the impact on government revenue. Because these responses vary with the policy in...

We develop a unifying framework for optimal income taxation in multi-sector economies with general patterns of externalities. Agents in this model are characterized by an N-dimensional skill vector corresponding to intrinsic abilities in N potentially externality-causing activities. The private...

We develop a theoretical model of security investments in a network of interconnected agents. Network connections introduce the possibility of cascading failures due to an exogenous or endogenous attack depending on the profile of security investments by the agents. The general presumption in...

Progress in closing differences in many objective outcomes for blacks relative to whites has slowed, and even worsened, over the past three decades. However, over this period the racial gap in well-being has shrunk. In the early 1970s data revealed much lower levels of subjective well-being...

The government often provides relief against large risks, such as disasters. A simple, general rationale for this role of government is considered here that applies even when private contracting to share risks is not subject to market imperfections. Specifically, the optimal private sharing of...

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household...
