In this paper, we use data from a corruption survey conducted among top politicians and high level civil servants in 290 Swedish municipalities in 2007 to investigate the effects of government size on corruption. We construct several measures of corruption based on the survey, and combine these...

Social trust is typically measured using surveys that ask people if they agree that most people can be trusted. A potential problem is that falling response rates plague these surveys. If nonresponses are systematic, comparisons of social trust over time will be biased. We examine social and...

Social trust is linked to many desirable economic and social outcomes, but the causality between trust and institutions is debated. Using new data from a representative sample of 2,668 Swedish expatriates (surveyed in the SOM Institute's Swedish Expatriate Survey 2014), we use variation in time...

More than 50 years after independence, the majority of countries in Sub-Saharan Africa remain poor with limited rates of economic growth. One of the most striking features of economic development on the sub-Saharan subcontinent is the remarkably poor performance of French colonies relative to...

Private universities, as opposed to publicly financed ones, are dominant in some countries and almost non-existent in others. We develop a dynamic model to demonstrate that private providers emerge as soon as they can profitably sell an elite signal to the most highly talented. As private...

Student mock elections are carried out in schools around the world in an effort to increase political interest and efficacy among students. There is, however, a lack of research on whether mock elections in schools enhance voter turnout in real elections. In this paper, we examine whether the...

Acemoglu and Johnson (2007) present evidence that improvements in population health do not promote economic growth. We show that their result depends critically on the assumption that initial health has no causal effect on subsequent economic growth. We argue that such an effect is likely,...

Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries...

We review the statistical models applied to test for heterogeneous treatment effects in the recent empirical literature, with a particular focus on data from randomized field experiments. We show that testing for heterogeneous treatment effects is highly common, and likely to result in a large...

The world has enjoyed huge improvements in population health during the last half century. But major health problems persist, particularly in tropical countries, which are still struggling with infectious diseases while increasingly having to deal with noncommunicable diseases. Several classic...
