This paper shows that whether natural resources are good or bad for a country's development depends crucially on the interaction between institutional setting and the type of resources that the country possesses. Some natural resources are for economical and technical reasons more likely to...

As a contribution to the recent debate about graduate education in Economics, we have surveyed all students enrolled in the Stockholm Doctoral Program in Economics. We believe that this is a good representative of a strong European graduate program which in the early 1990's adopted a US-style...

Several recent papers suggest that the negative association between natural resource intensity and economic growth can be reversed if institutional quality is high enough. We try to understand this result in more detail by decomposing the resource measure, using alternative measures of both...

In many parts of the world, soils poor in nutrients are farmed with little addition of fertilizer, further depleting the farmland. The very same farmers often face poor sanitary solutions. So-called ecological sanitation aims at providing sanitation and at recycling nutrients as fertilizer. This...

Donor aid is often regarded as being informally tied (aid increases donorrecipient exports) and this effect is, in general, interpreted as being harmful to aid recipients. However, in this paper, using a gravity model, we show that aid is also positively associated with recipient-donor exports....

We study re-entry to the workforce of fully retired persons, so-called unretirement, and whether the decision to resume work depends primarily on social or economic reasons. Using Swedish register data for already retired individuals older than 55, we find unretirement to vary between 6 and 14...

Promoting entrepreneurship has become an increasingly important part of the policy agenda in many countries. The success of such policies, however, rests in part on the assumption that entrepreneurship outcomes are not fully determined at a young age by factors that are unrelated to current...

The goal of this study is to examine trends in the importance of family background in determining adult income in Sweden. We investigate whether the association between family background and income in Sweden has changed for cohorts born 1932-1968. Our main finding is that the share of the...

We study peer effects in crime by analyzing co-offending networks. We first provide a credible estimate of peer effects in these networks equal to 0.17. This estimate implies a social multiplier of 1.2 for those individuals linked to only one co-offender and a social multiplier of 2 for those...
