We consider the problem of regressions with selectively observed covariates in a nonparametric framework. Our approach relies on instrumental variables that explain variation in the latent covariates but have no direct e ffect on selection. The regression function of interest is shown to be a...

Previous research suggests that there are substantial interactions between the unemployment insurance (UI) and the sickness insurance (SI) in Sweden. Moral hazard arises in the interplay between these two social insurance systems, since by reporting sick an unemployed person can postpone the UI...

In this paper, we study the short-run effect of salary receipt on mortality among Swedish public sector employees. By using data on variation in paydays across work-places, we completely control for mortality patterns related to, for example, public holidays and other special days or events...

While the health risks associated with smoking are well known, the impact on income distributions is not. This paper extends the literature by examining the distributional effects of a behavioral choice, in this case smoking, on net marginal Social Security tax rates (NMSSTR). The results show...

This paper looks at a specific type of moral hazard that arises in the interplay between two large public insurance systems in Sweden, namely the sickness insurance (SI) and the unemployment insurance (UI). Moral hazard can arise from the benefit size structure as for some unemployed persons,...

This paper examines the incentive effects caused by the interactions between unemployment insurance (UI) and sickness insurance (SI), two important components of Sweden's social insurance system. There are two main topics of interest: how the sickness report rate and the length of the subsequent...

The paper examines whether a worker's sick absence behaviour influences the risk of becoming unemployed. Swedish panel data are used to estimate the relationship between the incidence and duration of sick leave and subsequent unemployment. The results indicate that an increase in the number of...

This paper examines the incentive effects caused by the interactions between unemployment insurance (UI) and sickness insurance (SI), two important components of Sweden's social insurance system.

During the past decade there has been a growing opinion of including more than an income perspective in the examination of inequality. As a result a broad theoretical literature on the subject of multidimensional inequality is present. This can mainly be divided into three different parts:...

This study examines the uneven effects of air pollution from maritime ports on physical and mental health across racial groups. We exploit quasi-random variation in vessels in port from weather events far out in the ocean to estimate how port traffic influences air pollution and human health. We...
