We describe a model that integrates a multi-regional input-output model of the U.S. (50 states and the District of Columbia) with the national highway network. Interstate commodity shipments are placed on a congestible highway network. Simulations of major choke-point disruptions redirect...

Firms adjust to differences in market size and demand uncertainty by changing the frequency and size of their export shipments. In our inventory model, transportation costs and optimal shipment frequency are determined on the basis of demand as well as inventory and per shipments costs. Using a...

The direct impact of local public goods on welfare is relatively easy to measure from land rents. However, the indirect effects on home and job location, on land use, and on agglomeration benefits are hard to pin down. We develop a spatial general equilibrium model for the valuation of these...

For many years, Donald Shoup has been advocating cashing out free and underpriced curbside parking. How should this be implemented in practice, taking into account the stochasticity of curbside parking vacancies? Shoup has proposed setting neighborhood/period of the day-specific meter rates such...

This paper discusses how international trade is organized from export to trans-boundary transport to import. All evidence suggests that the transport sector is independent, may exercise market power and features strong economies of scale. We develop a model of a transport industry that operates...

Pricing greenhouse gases is widely understood as the most efficient approach for mitigating climate change, yet distributional effects hamper political acceptance. These distributional effects are especially important in transport, the fastest growing sector for greenhouse gas emissions. Using...

We build a general equilibrium model of endogenous communication, quality control and trade. We derive a structural gravity equation from the model and show that exogenous communication costs raise the costs of quality control and have a larger impact on products with a lower elasticity of...

The transition paths from plan to market have varied markedly across countries. Central and Eastern European and the Baltic countries, which opted for a fast and profound transformation of their institutions including business climates, rapidly narrowed the productivity gap with advanced...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

This paper studies the marginal product of private capital (MPK) with new data and a new framework to obtain a better understanding of international capital allocations and the Lucas Paradox (LP). Our point of departure is three influential studies of MPK's and, based on the most recently...
