"This paper investigates empirically whether financial incentives, and in particular governmental child subsidies, affect fertility. We use a comprehensive, nonpublic, individual-level panel dataset that includes fertility histories and detailed individual controls for all married Israeli women with two or more children from 1999-2005, a period with substantial variation in the level of governmental child subsidies but no changes in eligibility and coverage. We find a significant positive effect on fertility, with the mean level of child subsidies producing a 7.8 percent increase in fertility. The positive effect of child subsidies on fertility is concentrated in the bottom half of the income distribution. It is present across all religious groups, including the ultra-Orthodox Jewish population whose religious principles forbid birth control and family planning. Using a differences-in-differences specification, we find that a large, unanticipated reduction in child subsidies that occurred in 2003 had a substantial negative impact on fertility. Overall, our results support the view that fertility responds to financial incentives and indicate that the child subsidy policies used in many countries can have a significant influence on incremental fertility decisions"--National Bureau of Economic Research web site

Abstract
This paper analyzes the choice of deductible in insurance contracts that insure against a risk that, as is common, might materialize more than once during the life of the policy. As was established by Arrow (1963), from the perspective of risk-bearing costs, the optimal contract is one that uses an aggregate deductible that applies to the aggregate losses incurred over the life of the policy. Aggregate deductibles, however, are uncommon in practice. This paper identifies two disadvantages that aggregate deductibles have. Aggregate deductibles are shown to produce higher expected verification costs and moral hazard costs than contracts that apply a per-loss deductible to each loss that occurs. I further show that each of these disadvantages can make an aggregate deductible contact inferior to a contract with per loss deductibles. The results of the analysis can help explain the rare use of aggregate deductibles and, in addition, might explain why umbrella policies that cover all types of losses are rarely used.

We develop a structural econometric model to estimate risk preferences from data on deductible choices in auto insurance contracts. We account for adverse selection by modeling unobserved heterogeneity in both risk (claim rate) and risk aversion. We find large and skewed heterogeneity in risk attitudes. In addition, women are more risk averse than men, risk aversion exhibits a U-shape with respect to age, and proxies for income and wealth are positively associated with absolute risk aversion. Finally, unobserved heterogeneity in risk aversion is greater than that of risk, and, as we illustrate, has important implications for insurance pricing. (JEL D81, G22)
