We introduce a model of oligopoly dynamic pricing where firms with limited capacity face a sales deadline. We establish conditions under which the equilibrium is unique and converges to a system of differential equations. Using unique and comprehensive pricing and bookings data for competing...

We characterize the equilibrium and optimal resource allocations in a general equilibrium model of monopolistic competition with multiple asymmetric sectors and heterogeneous firms. We first derive general results for additively separable preferences and general productivity distributions, and...

We develop a model of a city populated by heterogeneous agents. Agents self-select into entrepreneurship, and entrepreneurs set up firms which hire workers. We characterize the equilibrium matching between firms and workers, as well as the within-city assignment of agents to locations. We then...

Colluding firms often exchange private information and make transfers within the cartels based on the information. Estimating the impact of such collusive practices" - known as the 'lysine strategy profile (LSP)" - on cartel duration is difficult because of endogeneity and omitted variable bias....

I study the simultaneous ownership of equity of competing companies by the same investor, i.e., common ownership, in 39,867 publicly listed corporations in 125 countries between 2000-2020. I construct a global data set to document the prevalence of common ownership in multiple forms, including...
