Previous studies on the influence of weather on Aedes aegypti dynamics in Puerto Rico suggested that rainfall was a significant driver of immature mosquito populations and dengue incidence, but mostly in the drier areas of the island. We conducted a longitudinal study of Ae. aegypti in two neighborhoods of the metropolitan area of San Juan city, Puerto Rico(More)
We study the diffusion of dispersed private information in a large economy. We assume that agents learn from the actions of others through both a private channel, which represents learning from local interactions, and a public channel, which represents learning from prices. We show that the private and public channels of information diffusion generate(More)
Entrepreneurial activity varies substantially across regions and sectors and appears to be related to the stigma of failure. To understand this phenomenon, I present a multiple-equilibrium model based on endogenous stigma of failure. Using private information, entrepreneurs choose whether to continue a project or to abandon it and raise funds to undertake a(More)
We have shown that the Centers for Disease Control and Prevention (CDC) autocidal gravid ovitraps (AGO trap) reduced the Aedes aegypti population and prevented mosquito outbreaks in southern Puerto Rico. After showing treatment efficacy for 1 year, we deployed three traps per home in an area that formerly did not have traps and in a site that served as the(More)
Urban dengue is common in most countries of the Americas, but has been rare in the United States for more than half a century. In 1999 we investigated an outbreak of the disease that affected Nuevo Laredo, Tamaulipas, Mexico, and Laredo, Texas, United States, contiguous cities that straddle the international border. The incidence of recent cases, indicated(More)

This paper examines how a decisionmaker who is only partially aware of his temptations learns about them over time. In facing temptations over time, individuals use their experiences to forecast future self-control problems and choose the appropriate level of commitment. I demonstrate that rational learning can be perpetually partial and need not result in(More)

We study the optimal Mirrlees taxation problem in a dynamic economy with idiosyncratic (productivity or preference) shocks. In contrast to the standard approach, which implicitly assumes that the mechanism is operated by a benevolent planner with full commitment power, we assume that any centralized mechanism can only be operated by a self-interested(More)
I provide empirical evidence that badly governed firms respond more to aggregate shocks than do well governed firms. I build a simple model where managers are prone to over-invest and where shareholders are more likely to tolerate such a behavior in good times. The model successfully explains the average profit differences as well as the cyclical behavior(More)
Limited success has been achieved using traditional vector control methods to prevent the transmission of dengue viruses. Integrated control programs incorporating alternative tools, such as gravid ovitraps (lethal ovitraps and sticky ovitraps) may provide greater potential for monitoring and reducing vector populations and dengue virus transmission. We had(More)
