This paper analyzes the macroeconomic and welfare effects of population aging and Social Security reform. First, a stochastic overlapping-generations model with heterogeneous agents is carefully extended to an aging society. The model uses the intermediate population projection of the Trustee...

This paper provides a preliminary investigation into the lifetime cost of children upon a household's lifetime wealth. By comparing the lifetime cost function of a household with children compared to the lifetime cost function of a household without children, an intertemporal equivalence scale...

This paper focuses on the identification and estimation of the intertemporal and intratemporal elasticities of substitution for the wife and separately for the husband using individual Euler equations. To that end, the household is represented as a group of agents making joint decisions. By...

We use household survey data to construct a direct measure of absolute risk aversion based on the maximum price a consumer is willing to pay to buy a risky asset. We relate this measure to a set of consumers' decisions that in theory should vary with attitude towards risk. We find that elicited...

Theories on the formation of information cascades have been tested in experimental settings in which players publicly announce binary expectations of a binary event based on private signals and preceding public announcements. We replicate and supplement the experimental data collection by...

This paper introduces a tractable, structural model of subjective beliefs. Since agents that plan for the future care about expected future utility flows, current felicity can be increased by believing that better outcomes are more likely. On the other hand, expectations that are biased towards...

We examine an economy in which the cost of consuming some goods can be reduced by making commitments to consumption levels that do not vary across states. For example, moral hazard and matching considerations may make it cheaper to produce housing services via owner-occupied than rented housing,...

This paper studies how the arrival of more precise information affects welfare in an economy with incomplete and differential information. We consider a single period, pure exchange economy with aggregate uncertainty in which agents show different attitudes towards risk: wealthy individuals are...

I argue in favor of a competitive screening approach for studying the question of coalition formation in exchange economies under asymmetric information. I obtain a new notion of core that refines Wilson (1978)'s coarse core. It is nonempty under the standard regularity conditions. I also...

This paper analyzes a bilateral trade problem where the seller makes hidden investment that influences the buyer's private valuation. Complete contracts can be written on observable trade decisions. It is shown that efficiency level in investment and trade is negatively related to the scope of...
