Risk and time are intertwined. The present is known while the future is inherently risky. Discounted expected utility provides a simple, coherent structure for analyzing decisions in intertemporal, uncertain environments. However, we document robust violations of discounted expected utility,...

this assumption. If there is no annuity market, then the welfare cost of survival ambiguity is large and regressive …. Individuals would pay as much as 1% of total lifetime consumption for immediate resolution of ambiguity and the bottom income …, survival ambiguity is welfare improving because it allows competitive insurance companies to pool risk across survival types …

We provide a user's guide to exotic' preferences: nonlinear time aggregators, departures from expected utility, preferences over time with known and unknown probabilities, risk-sensitive and robust control, hyperbolic' discounting, and preferences over sets ( temptations'). We apply each to a...

This paper revisits the Home Bias Puzzle -- the relatively low interna- tional diversification of portfolios. We suggest that part of the diversifi- cation puzzle may be due to reliance on the conventional CAPM model as the benchmark predicting patterns of diversification. We compare the asset...

Studies of risk preference have empirically established two regularities that are inconsistent with the canonical expected utility model: (1) risk aversion over small gambles greatly exceeds risk aversion over larger stakes and (2) insurance buyers play the lottery. This paper characterizes risk...

This paper develops a method of estimating the coefficient of relative risk aversion (g) from data on labor supply. The main result is that existing estimates of labor supply elasticities place a tight bound on g, without any assumptions beyond those of expected utility theory. It is shown that...

Greater … ambiguity aversion may lead to more or less abatement depending on the details of the model. We then extend our analysis to a …

Vector autoregressions (VARs) are flexible time series models that can capture complex dynamic interrelationships among macroeconomic variables. However, their dense parameterization leads to unstable inference and inaccurate out-of-sample forecasts, particularly for models with many variables....

Variation in economic preferences is systematically related to both individual and aggregate economic outcomes, yet little is known about the origins of the worldwide preference variation. This paper uses globally representative data on risk aversion, time preference, altruism, positive...
