Is variation in empirical mortality across populations consistent with a hypothesis of selection? To examine this proposition an extended frailty mortality model is put forward; incorporating biological frailty; a common non-parametric hazard, joint for men and women, rep-resenting endogenous...

This paper studies estimation of the number and location of modes of the wage distribution. The location of the modes can be used to estimate the cutpoints of the equilibrium wage distribution (Bowlus, Kiefer, and Neumann, 1995) in the presence of measurement error. These cutpoints can be used...

What accounts for Sweden’s high COVID death rate among the Nordics? One factor could be Sweden’s lighter lockdown. But we suggest 15 other possible factors. Most significant are:(1) the “dry-tinder” situation in Sweden (we suggest that this factor alone accounts for 25 to 50% of Sweden's...

Tuberculosis (TB) is a leading cause of death worldwide according to the WHO. This paper estimates the effect of TB dispensaries, designed to prevent the spread of the disease before the advent of modern medicine. Our difference-in-differences estimation reveals that the roll-out of the TB...

We use Brazilian matched employer-employee data to provide new evidence on gender disparities in labor market sorting on wages and workplace safety. We show that women and men sort in highly disparate, but systematic, ways on the basis of physical risk, despite sorting almost identically on...

Car ownership is lower in urban areas, which is probably related to the availability of better public transport. Better public transport thus may offer the possibility to relieve the many problems (congestion, health, and parking) associated with the presence of cars in urban areas. To...
