讲座题目：An Anatomy of an Online Job Market: Evidence for Directed Search with Multiple Application

讲座提要：This study contributes to the micro-foundation of a directed search model with multiple applications using application-level data from a Chinese online job platform. In a directed search model with multiple applications, job applicants’ optimization problem becomes choosing a portfolio of job postings they will apply to. We empirically examine the properties of portfolios and how those properties are related to personal characteristics and market conditions. Our main findings are twofold. First, we verified one key prediction from previous theoretical literature---a worker’s optimal strategy is to apply to both “safe” low wage and “risky” high wage jobs. Second, we examined the properties of MRS (of wage for probabilities), tested the consistency with the theoretical literature, and explored the heterogeneity across the population.

讲座题目：The Child Quantity-Quality Trade-off: Heterogeneity, Generalization, and New Evidence

讲座提要：Do population control policies promote human capital development? Empirical analyses on the quantity-quality trade-off of children show little consensus on its sign and magnitude. We build a theory of rationed fertility that distinguishes between desired and undesired fertility changes. While a desired increase in fertility generates a positive rationing income effect on child quality, an undesired increase has a negative rationing income effect. To empirically test the theory, we combine the natural experiment of twin births with China's “One-child” policy. Consistent with our theory, we find that the twinning shock has a smaller negative effect on children's education if the mother is under higher exposure to the “One-child” policy. Our study reconciles recent empirical literature on the heterogeneous fertility effects on child quality, and advances our understanding of how population control policy affects human capital investment and economic development.
