In Chapter 1, I document a negative (positive) relationship between changes in large (small) blockholders' ownership and abnormal returns. The evidence in this paper suggests that an increase in the relatively large blockholders' ownership raises the consumption of private benefits while an...

We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographical characteristics: the number and distribution of outbreaks, population size, density, and agents' movements. We show that several invariance properties of the SIR model with respect to...

In this paper we model a decision maker who must exert costly effort to complete a single task by a fixed deadline. Effort costs evolve stochastically in continuous time. The decision maker will then optimally wait to exert effort until costs are less than a given threshold, the solution to...
