We use individual and multi-level data from Zambia on child nutritional health to test the absolute income hypothesis (AIH), the relative income hypothesis (RIH) and the income inequality hypothesis (IIH). The results confirm a non-linear positive relation between economic resources and health,...

We use administrative data on Swedish lottery players to estimate the causal impact of wealth on players' own health and their children's health and developmental outcomes. Our estimation sample is large, virtually free of attrition, and allows us to control for the factors such as the number of...

This essay contributes in two ways to the literature on the effects of economic circumstances on health. First, it deals with reverse causality and omitted variable bias by exploiting exogenous variation in inherited wealth generated by the unexpected repeal of the Swedish inheritance tax....

This paper analyses the effects of independent-school competition on Sweden's performance in TIMSS, an international low-stakes test in mathematics and science among students in year 8. Exploiting variation in independent-school enrolment shares across counties over time, it finds that...

We provide a model that explains the following empirical observations: i) private ownership is more efficient than public ownership, ii) privatizations are associated with increases in efficiency and iii) the increase in efficiency predates the privatization. The two key mechanisms explaining...

I develop a model of public sector contracting based on the multitask framework by Holmström and Milgrom (1991). In this model, an agent can put effort into increasing the quality of a service or reducing costs. Being residual claimants, private owners have stronger incentives to cut costs than...

There are several theoretical accounts of public sector outsourcing. We note that leading theories give different predictions of the influence of political variables and test the predictions on a Swedish data set in which outsourcing varies between municipalities and over time as well as between...

A wide range of services provided by the public sector are credence goods, i.e., services for which the producer has private information whether a certain treatment is needed or not. This paper studies how ownership affects the incentives for producers to reveal such information to public...

We survey the literature on the effects of public sector outsourcing. Guided by theory, we systematically arrange services according to the type and magnitude of their contractibility problems. Taken as a whole, the empirical literature indicates that public sector outsourcing generally reduces...
