The authors show that estimated productivities of labor and capital, which rationalize trade flows across countries, are related to total factor productivities, which rationalize output differences across countries. They present evidence that these productivities from trade are related to the...

-hub center problem is an extension of the deterministicversion which aims to minimize the longest origin-destination path in a hub and spokenetwork. Considering the stochastic nature of travel times on links is important when designing anetwork to guarantee the quality of service measured by a...

We study the single allocation hub covering problem, which is a special case of the general hub locationproblem. The hub covering problem is also an important extension to traditional network coveringproblems. Hubs are located at some nodes in the network and are used to facilitate –...

This paper studies gender differences in labor market outcomes using data from an Internetbased CV database. The women in the database get fewer firm contacts than men, and we show that this is partly explained by differences in education, experience and other skills, is not explained by...

Reported attitudes towards immigrants are sometimes used as a proxy for ethnic discrimination. However, there is little empirical evidence of a link between attitudes and discrimination. In this paper, we use survey data on people's attitudes towards immigrants combined with data on ethnic...

This paper analyzes how student achievement is affected by resource increases in the Swedish compulsory school due to a special government grant that was enforced in the academic year of 2001/02. The analysis is based on register data that contains all students that completed compulsory...

I decompose the cross-sectional variance of male annual earnings in Sweden between 1960 and 1990 into permanent and transitory components. The transitory variance increased until the early 1970s, declined during the remainder of the decade and then rose again during the second half of the 1980s....

We examine peer effects in welfare use among immigrants to Sweden by exploiting a governmental refugee placement policy. We distinguish between the quantity of contacts - the number of individuals of the same ethnicity - and the quality of contacts - welfare use among members of the ethnic...

This paper analyses crucial design features of unemployment insurance (UI) policies. We examine three different means of improving the efficiency of UI: the duration of benefit payments, monitoring in conjunction with sanctions, and workfare. To that end we develop a quantitative model of...
