We investigate the influence of diagonal and off-diagonal disorder potentials on superconductivity in an attractive Hubbard model. The study is motivated by recent experimental and theoretical interest in understanding the microscopic mechanism by which impurities destroy superconductivity. In...

Recent studies analyzing the effects of religion on various economic, social, health and political outcomes have been largely associational. Although some attempts have been made to establish causation using instrument variable (IV) or difference-in-difference (DID) methods, the instruments and...

In this paper, we analyze the effects of a broad set of measures of religiosity—religious attendance, prayer frequency, and self-reported importance of religion—on risky health behaviors at different stages of the life course. Using the National Longitudinal Study of Adolescent Health (Add...
