This paper explores sources of complexity in dynamic optimization, examining how individuals navigate variation in incomes, prices, and returns in ten-period consumption-saving decisions. Our findings reveal that dynamic optimization poses significant challenges, resulting in suboptimal choices...

Preferences for schools are important determinants of equitable access to high-quality education, effects of expanded choice on school improvement and school choice mechanism design. Standard methods for estimating consumer preferences are not applicable in education markets because students do...

We study crises characterized by large adjustments of aggregate consumption through their microlevel patterns. We show that leading theories designed to explain aggregate consumption dynamics differ markedly in their cross-sectional predictions. While theories based on financial frictions...

This paper presents a model of consumption behavior that explains the presence of 'wealthy hand-to-mouth' consumers using a mechanism that differs from those analyzed previously. We show that a two-asset model with temptation preferences generates a demand for commitment and thus illiquidity,...

Long-term data show that the dynamic efficiency condition <i>rg</i> holds when <i>g</i> is represented by the average growth rate of real GDP if <i>r</i> is the average real rate of return on equity, <i>E(r^e)</i>, but not if <i>r</i> is the risk-free rate, <i>r^f</i>. This pattern accords with a simple disaster-risk model calibrated to...

We propose an empirical implementation of the consumption-investment problem using the martingale representation alternative to dynamic programming. Our method is based on the direct observation of state prices from options data. This greatly simplifies the investor's task of specifying the...

In this paper, we consider economies in which agents are privately informed about their skills, which are evolving stochastically over time. We require agents' preferences to be weakly separable between the lifetime paths of consumption and labor. However, we allow for intertemporal...

The controversy over whether and how much to charge for health products in the developing world rests, in part, on whether higher prices can increase use, either by targeting distribution to high-use households (a screening effect), or by stimulating use psychologically through a sunk-cost...

Satisfactory calculations of the welfare cost of aggregate consumption uncertainty require a framework that replicates major features of asset prices and returns, such as the high equity premium and low risk-free rate. A Lucas-tree model with rare but large disasters is such a framework. In a...
