Using registry data on every employed Norwegian woman giving birth to her first child during the period 1995–2008, we describe patterns of certified and paid sick leave before, during and after pregnancy. By following the same women over time, we can explore how observed sick leave patterns...

In 2004 Norwegian authorities announced a reform introducing dividend taxation for personal (but not corporate) owners to take effect starting in 2006. This change provided incentives to maximize dividends in 2004 and 2005, and to retain earnings in the following years. Using Norwegian registry...

We estimate the effect of exposure to plant closure on crime using an individual-level panel data set containing criminal charges for all unmarried and employed Norwegian men below the age of 40. Men originally employed in plants that subsequently closed are 14 percent more likely to be charged...

Two districts of Oslo started to offer five-year-old children free preschool four hours a day. We analyze the effect of this intervention on the school performance of the children from immigrant families 10 years later (age 16). Our difference-in-difference approach takes advantage of the...

Classical theory states that the optimal fine equals the damage caused by the crime divided by the probability of detection. But does such an optimal fine exist? We focus on emissions from production, and, even if we assume that the damage function is perfectly known, we still show that the...

Properties of estimators of long-run parameters in a polynomial regression with nonstationary, strongly exogenous regressors are considered in the context of the Environmental Kuznets Curve using Monte Carlo simulations. Standard inferential procedures seem to work well in this context.

Using variation across geographic regions, a number of studies from the U.S. and other developed countries have found more deaths in economic upturns and less deaths in economic downturns. We use data from regions in Norway for 1977–2008 and find the same pro-cyclical patterns. Using...

Several recent experimental studies have confirmed that social sanctioning can enforce cooperation in public good situations. These studies consider situations where the participants, who have monetary interest in the outcome of the public good game, inflict social sanctioning. The present...
