Utilizing a panel data set of 42 states over the period 1959-1994, this paper estimates a rational addiction model for liquor consumption for the US. The empirical evidence is consistent with the rational addiction hypothesis proposed by Becker and Murphy. However, the results are sensitive to the assumption of homogeneity across states or over time.
This paper contrasts the performance of heterogeneous and shrinkage estimators versus the more traditional homogeneous panel data estimators. The analysis utilizes a panel data set from 21 French regions over the period 1973-1998 and a dynamic demand speci…cation to study the gasoline demand in France. Out-of-sample forecast performance as well as the… (More)
Ionospheric scintillation degrades GPS positioning accuracy in a number of ways. Along each scintillating satellite-receiver link, errors are introduced in the measurements of pseudorange and carrier phase. When the scintillation on a given link is sufficiently intense, the link becomes intermittently unavailable for use in the position solution. The loss… (More)
Complete eradication of HIV-1 infection is impeded by the existence of latent HIV-1 reservoirs in which the integrated HIV-1 provirus is transcriptionally inactive. Activation of HIV-1 transcription requires the viral Tat protein and host cell factors, including protein phosphatase-1 (PP1). We previously developed a library of small compounds that targeted… (More)
1. Abstract We describe a technique to determine the temperature of a Resident Space Object (RSO) from multiple infrared (IR) bands. The characteristic temperature of an object is the temperature of the Planck function that has the closest least squares fit to the observed irradiance in at least three infrared bands. The characteristic temperature and the… (More)
