Paper [I] studies equality of opportunity in Sweden. The distinction between circumstances that constrain an individual’s opportunities and the individual choices also affecting a particular outcome is the main idea of theories of equality of opportunity. In this study, equality of opportunity...

In this study, the consequences of unemployment for a Swedish sample of couples are analyzed. The purpose is to estimate the possible income replacement that a spouse can provide. Unemployment can also affect the probability that the couples split up. Since not all couples remain in the...

Lone mothers are overrepresented among poor people in many European countries. In 1998, in Norway, a welfare reform increased the amount of benefits and introduced working requirements. Using a quasi-experimental model, Mogstad and Pronzato (2012) find a positive effect of the reform on lone...

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...

This paper develops a model for dynamic binary choice panel data that allows for unobserved heterogeneity to be arbitrarily correlated with covariates. The model is of the exponential type. We derive moment conditions that enable us to eliminate the unobserved heterogeneity term and at the same...

Using recent advances in panel data estimation techniques, we find that an appreciation of the US dollar exchange rate leads to a significant decline in oil demand for a sample of 65 oil-importing countries. The estimated effect turns out to be much larger than the impact of a shift in the...

Plants' entry and exit behaviour in Swedish municipalities are studied within a fixed-effect, integer-valued autoregressive model. Based on eight industrial sectors, 1985--1993, and all municipalities, models are estimated by a generalized method of moment estimator. Influences on entry and exit...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated...

Student achievement has been identified as important contributor to economic growth. This paper investigates the relationship between redistributive government activities and investment in human capital measured by student performance in international comparative tests in Mathematics and Science...

This thesis consists of five self-contained papers on factor demand and market power. <p> The main objective of Paper [I] is to analyze potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as a fuel in energy generation. The background to the problem...</p>
