We provide a condition which is both necessary and sufficient for uniform validity of asymptotic approximations using the delta-method, that is for uniform negligibility of the remainder of such approximations. This condition is easily verified and permits to identify settings and parameter...

The relatively low degree completion rate of U.S. college students has prompted debate over the extent to which the problem is attributable to the students or to their choice of colleges.  Estimating the impact of initial college choice is confounded by the non-random nature of college...

Previous studies of war and infectious disease have generated inconsistent findings on the interrelationships of these phenomena. This study investigates the association of war and democracy with HIV prevalence using time-series cross-section (TSCS) analysis of a new data set that is more...

Estimates of HIV prevalence are important for policy in order to establish the health status of a country's population, to evaluate the effectiveness of population-based interventions and campaigns, to identify the most at risk members of the population, and to target those most in need of...

Structural coloration produces some of the most brilliant colors in nature and has many applications. Motivated by the recently proposed transparent displays that are based on wavelength-selective scattering, here we consider the new problem of transparent structural color, where objects are...

To what extent can changes in the distribution of wages be explained by changes in labor supply of various groups (due to demographic change, migration, or expanded access to education), and to what extent are other factors (technical and institutional change) at work? We develop a flexible...

Hybrid nanostructures that couple plasmon and exciton resonances generate hybridized energy states, called plexcitons, which may result in unusual light-matter interactions. We report the formation of a transparency dip in the visible spectra of colloidal suspensions containing silver...

We prove that the unilateral substitutability property introduced in Hatfield and Kojima (2010) implies the substitutable completability property from Hatfield and Kominers (2014). This paper provides a novel linkage between these two sufficient conditions for the existence of a stable matching...
