We study response behavior of New York City parking-ticket recipients by analyzing administrative data on 6.6 million tickets issued to 2 million individuals over two years. Exploiting variation (from a policy change and a field experiment) in letters sent to recipients, we find that forgetting...

Labor supply is unresponsive to permanent changes in wage rates. Thus, income and substitution effects cancel, but are they both close to zero or both large? This paper develops a theory of labor supply where income and substitution effects cancel, taking into account optimization over time,...

In this paper, we derive and estimate relationships governing variable utilization of capital and labor for a firm solving a dynamic cost-minimization problem. Our method allows for (i) imperfect competition, (ii) increasing returns to scale, (iii) unobserved changes in utilization, (iv)...

Individuals' preferences underlying most economic behavior are likely to display substantial heterogeneity. This paper reports on direct measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These experimental measures are based on survey...
