We study the reaction of financial markets to aggregate liquidity shocks when traders face cognition limits. While each financial institution recovers from the shock at a random time, the trader representing the institution observes this recovery with a delay, reecting the time it takes to...

Somaliland has recently developed an unexpected democracy after seceding from chaos-ridden Somalia, while turning its port of Berbera into a success story, competing successfully with the long established ones in the Horn of Africa. A simple game-theoretic model is used to explain why the...

We formulate and estimate a structural model for travel demand, in which users have hetero- geneous preferences and make their transport decisions considering the network congestion. A key component in the model is that users have incomplete information about the preferences of other users in...

Because soft drink (SD) consumption is considered to be a contributor to the ’epidemic’ of obesity, there is a growing interest in evaluating the impact on SD consumption of alternative tax policies. In this paper, we propose a methodology to evaluate the impact of taxation of a food market...

We formalize the taxpayer burden implied by various bank restructuring plans. Even assuming minimal frictions, in spirit of Modigliani and Miller (1958), when debt contracts cannot be changed, transfers from the taxpayer (in a Net Present Value sense) are necessary. Debt holders benefit from a...

We develop a theoretical model where a redistribution of bank capital (e.g., due to reckless trading and/or faulty risk management) leads to a “freeze” of the interbank market. The fire-sale market plays a central role in spreading the crisis to the real economy. In crisis, credit rationing...

This paper quantifies the relationship between market size and innovation in the pharmaceutical industry using improved, and newer, methods and data. We find positive significant elasticities of innovation to expected market size with a point estimate under our preferred specification of 0.23....

The Kyoto and Copenhagen Protocols on climate change mitigation postponed the specification of binding commitments to a future negotiation. This paper analyzes the strategic implications of delayed negotiations. While, as iswell-understood, the incentive to free ride leads to excessive emissions...

In this paper, we discuss the choice for build-operate-and-transfer (BOT) concessions when governments and …rm managers do not share the same information regarding the operation characteristics of a facility. We show that larger shadow costs of public funds and larger information asymmetries...
