This paper studies the coordination burden for firms that pursue variety as their main product strategy. We propose that product variety magnifies the tension between scale economies in production and scope economies in distribution, giving rise to complex sourcing relationships. Sourcing...

We consider an electricity market organized with two settlements: one for a pre-delivery (day-ahead) market and one for real time, where uncertainty regarding production from non-dispatchable energy sources as well as variable load is resolved in the latter stage. We formulate two models to...

This paper establishes the existence of multiple equilibria in infinite-horizon open- economy models in which the value of tradable and nontradable endowments serves as collateral. In this environment, the economy displays self-fulfilling financial crises in which pessimistic views about the...

We study bank supervision by combining a theoretical model distinguishing supervision from regulation and a novel dataset on work hours of Federal Reserve supervisors. We highlight the trade-offs between the benefits and costs of supervision and use the model to interpret the relation between...

We explore the consequences of safe asset scarcity on aggregate demand in a stylized IS-LM/Mundell Fleming environment. Acute safe asset scarcity forces the economy into a "safety trap" recession. In the open economy, safe asset scarcity spreads from one country to the other via capital flows,...

This research project followed an earlier similar project on Nigeria, applying the same methods. A sample of manufacturers was surveyed to document their responses to infrastructure deficiencies in electricity, water, transport, telecommunications, and waste disposal. They found the...

Conventional economic models in airport regulation assume, that airports have considerable market power and may exploit it against airlines. Given, that many airports are served by only a limited number of airlines, mono- or oligopsony relationships may exist. This paper relaxes therefore this...

This paper reviews the literature on the fiscal policy instruments commonly used to reduce transport sector externalities. The findings show that congestion charges would reduce vehicle traffic by 9 to 12 percent and significantly improve environmental quality. The vehicle tax literature...
