We establish nonparametric identification in a class of so-called index models using a novel approach that relies on general topological results. Our proof strategy imposes very weak smoothness conditions on the functions to be identified and does not require any large support conditions on the...

How to evaluate and compare social prospects when there may be a risk on i) the actual allocation people will receive; ii) the existence of these future people; and iii) their preferences? This paper investigate this question that may arise when considering policies that endogenously affect future...

Recent theoretical work in the economics of climate change has suggested that climate policy is highly sensitive to "fat-tailed" risks of catastrophic outcomes (Weitzman, 2009b). Such risks are suggested to be an inevitable consequence of scientific uncertainty about the effects of increased...

We examine how different welfarist frameworks evaluate the social value of mortality risk-reduction. These frameworks include classical, distributively unweighted cost-benefit analysis — i.e., the “value per statistical life” (VSL) approach — and three benchmark social welfare functions...

In this paper, we employ a unique tax experiment and dataset in a highly salient tax rate environment to examine consumer response to complex and uncertain tax reforms. Tax reforms raise some fundamental questions in public finance: How does consumption respond to tax change? How is the tax...

Exploiting French survey data, we empirically ascertain whether earnings uncertainty and borrowing constraints decrease households demand for risky assets, consistent with theoretical predictions. A major empirical problem is the potential endogeneity bias of income risk, as more risk averse...
