Does an income tax harm economic efficiency more the more progressive it is? Public economics provides a strong case for a definite ‘yes’. But at least three forces may pull in the other direction. First, low-wage workers may on average have more elastic labour supply schedules than...

Models that allow for non-cooperative as well as cooperative behavior of families are estimated on data from Norway in 1993 and 1994. The husband is eligible for early retirement while the wife is not. The models aim at explaining labor supply behavior of married couples the first twelve months...

In 1988, an early retirement program (AFP) was introduced in Norway for the 66-years-old. Since then, AFP has gradually been extended and by now it covers workers aged 62-66. In this paper we employ a multinominal logit model to study the transition between states in the labour market. The model...

In the simple Allingham-Sandmo portfolio model of tax evasion an expected utility maximizer will cheat more than what is estimated in empirical studies. Two main types of explanation have been suggested as solutions to this puzzle: (1) Tax payers act according to some non-expected utility...

TNF-alpha inhibitors represent one of the most important areas of biopharmaceuticals by sales, with three blockbusters accounting for 8 % of total pharmaceutical sale in Norway. With use of a unique natural policy experiment in Norway, this paper examines to what extent the identity of the...

Using an extensive longitudinal dataset extracted from the Norwegian Prescription Database (NorPD) containing all prescriptions written in the period January 2004 to June 2007, we selected two particular drugs (chemical substances) used against cholesterol. The two brand-name products on the...

TNF-alpha inhibitors represent one of the most important areas of biopharmaceuticals by sales, with three blockbusters accounting for 8 % of total pharmaceutical sale in Norway. With use of a unique natural policy experiment in Norway, this paper examines to what extent the identity of the...

In order to estimate labour supply responses among older people we have employed a very simple model of retirement decisions that can be estimated on a single cross-section sample, and still be given a structural interpretation in terms of inter-temporal decisions. The model is estimated on...

Organic production techniques are an increasing, though minor so far, part of agriculture, and organic wines are increasingly produced and appreciated. Nevertheless, since the organic technique is more costly, a crucial question is whether organic wines benefit from a price premium. In this...

The paper compares the pattern of wage assimilation of foreigners with both native immigrants and local natives in Italy, a country with large internal and international migration. This comparison, not yet exploited, yields understanding of the role played by language and knowledge of social...
