We present a general, dynamic model of within-season harvesting competition in a sherymanaged with individual transferable quotas. Markov-Perfect equilibrium harvesting andquota purchase strategies are derived using numerical collocation methods. Our approachallows direct examination of harvest...

We employ an open economy general equilibrium model to investigate the effects of governmentenergy policy, with an emphasis on corn-based ethanol, on the U.S. economy. The modelspecification incorporates world and domestic markets, assumes pollution costs from fuelconsumption, and allows...

This paper studies equilibrium search and learning in a dynamic shing gamethat is played by independent shermen and by members of an information sharingCooperative. Once collected, information about the location of productive sh-ing sites is an excludable public good. We show that independent...

Models of fishing behavior rarely incorporate the complexities of marine ecosystems,multiple-stock harvest technologies, and regulations present in real world marinefisheries. We introduce a structural model of a multi-species, weak-output-disposabilityharvest technology. A latent...

This paper estimates a structural model of multiple-species harvesting costs in the easternGulf of Mexico reef fish fishery. The calibrated model is used to predict fleet size, vessellevelharvesting activity and fleet-wide revenues and costs that are expected under a proposedindividual fishing...

This paper considers the problem of multi-species fisheries managementwhen targeting individual species is costly and at-sea discards of fish by fishermenare unobserved by the regulator. Stock conditions, ecosystem interaction, technologicalspecification, and relative prices under which at sea...

This paper examines search with active learning and correlated information. We firstdevelop a simple model to show how correlation affects the decision to acquire information.A unique data set on fishing site choice by mid-Atlantic clam fishermen is used to test themodel predictions. Results...

This paper uses a semi-parametric empirical model to estimate the economic benefitsof adopting a property rights-based management program in the Gulf of Mexico grouperfishery. The analysis predicts that a rights-based fleet will be comprised of fewer, morecost efficient boats than under the...

People behave pro-socially in a wide variety of situations that standard economic theory is unable to explain. Social comparison is one explanation for such pro-social behavior: people contributeif others contribute or cooperate as well....

This paper investigates the relation between social capital and crime. The analysis contributes to explaining why crime is so heterogeneous across space. By employing current and historical data for Dutch municipalities and by providing novel indicators to measure social capital, we find a link...
