BACKGROUND Although pricing policies for alcohol are known to be effective, little is known about how specific interventions affect health-care costs and health-related quality-of-life outcomes for different types of drinkers. We assessed effects of alcohol pricing and promotion policy options in various population subgroups. METHODS We built an(More)
Modelling Charitable Donations to an Unexpected Natural Disaster: Evidence from the U.S. Panel Study of Income Dynamics Using household-level data, we explore the relationship between donations to the victims of the 2004 Indian Ocean tsunami disaster and other charitable donations. The empirical evidence suggests that donations specifically for the victims(More)
We explore the relationship between self-employment and attitudes towards financial risk using individual level data drawn from the US Panel Study of Income Dynamics (PSID), which includes measures of individuals’ attitudes towards hypothetical gambles allowing us to explore the implications of interpersonal differences in risk attitudes for the probability(More)
We explore the determinants of debt and growth in debt at the individual and household level. The focus is on the influence of expectations of individuals and households regarding their future financial situation. Our theoretical model predicts a positive association between the quantity of debt and optimism. The empirical findings provide convincing(More)
Following in Your Parents’ Footsteps? Empirical Analysis of Matched Parent-Offspring Test Scores In this paper, we explore whether an intergenerational relationship exists between the reading and mathematics test scores, taken at age 7, of a cohort of individuals born in 1958 and the equivalent test scores of their offspring measured in 1991. Our results(More)
Increasing data locality is a good way to alleviate the gap between memory latency and processor speed. Structure layout optimization is one way to improve spatial locality and consequently improve runtime performance by rearranging fields inside objects. This paper examines modifying IBM's JVM with the ability to reorder fields inside Java objects from(More)
The aim of this paper is to explore how interpersonal variation in risk preference affects human capital investment and, hence, wage growth. To date, there has been a distinct lack of empirical research in this area despite the fact that the risk preference of individuals plays a key role in the theoretical models of human capital accumulation. We(More)
