Multimodal Transport Networks
The movement of goods from origin to destination takes place over multiple modes of transportation. Correspondingly, intermodal terminals play an important role in facilitating transportation over the multimodal network. This paper studies multimodal transport networks and their impact on infrastructure investments. We propose a tractable theory of transportation across domestic transportation networks with multiple modes of transportation by embedding multimodal routes into a spatial equilibrium model with endogenous stochastic route choice. We calibrate the model to US domestic freight ...

Spoils of War: Trade Shocks and Segmented Labor Markets in Spain during WWI
How does intranational factor mobility shape the welfare effects of a trade shock? I provide evidence that during WWI, a demand shock emanated from belligerent countries and affected neutral Spain. Within Spain, labor predominantly reallocated locally, while the most affected provinces experienced drastic increases in wages and consumer prices. Embedding imperfect labor mobility in an economic geography model, I show that external demand shocks can improve allocative efficiency, but asymmetric shocks cause localized increases in wages and consumer prices instead of reallocation. Adjusting an ...

Globalization and Heterogeneity: Evidence from Hollywood
Linder (1961) conjectured that taste differences could impede trade flows. We extend Krugman (1980) to allow for producers that face taste heterogeneity with volatile demand. Consumers are characterized by different taste over product attributes and idiosyncratic risk. Firms face a portfolio type of problem where they trade off supplying the largest consumer groups against higher exposure to group-specific risk. We develop an empirical strategy to estimate consumer taste from observed market shares across multiple distinct markets of the same product, as well as the key parameters that pin ...
