- We explore the relationship between attractiveness and risk taking in chess. We use a large international panel dataset on high-level chess competitions which includes a control for the players’ skill in chess. This data is combined with results from a survey on an online labor market where participants were asked to rate the photos of 626 expert chess players according to attractiveness. Our results suggest that male chess players choose significantly riskier strategies when playing against an attractive female opponent, even though this does not improve their performance. Women's strategies are not affected by the attractiveness of the opponent.

Tidskriftsartikel (refereegranskat)abstract
- This paper aims to measure differences in risk behavior among expert chess players. The study employs a panel data set on international chess with 1.4 million games recorded over a period of 11 years. The structure of the data set allows us to use individual fixed-effect estimations to control for aspects such as innate ability as well as other characteristics of the players. Most notably, the data contains an objective measure of individual playing strength, the so-called Elo rating. In line with previous research, we find that women are more risk-averse than men. A novel finding is that men choose more aggressive strategies when playing against female opponents even though such strategies reduce their winning probability.

Studying the Interplay of Immigration and Welfare States
- 2008
-
Doktorsavhandling (övrigt vetenskapligt)abstract
- A comparative study of net transfers for different immigrant groups: Evidence from GermanyThis paper analyzes determinants of net transfers for immigrants living in Germany in 2002, coming from five different countries. Net transfers refer to the net amount of costs and tax payments in the public budget account. The study focuses on differences/similarities between outcomes. The results suggest that employment situation and family composition explain a major part of the differences, but also that legal immigration status granted on arrival in Germany seem to matter.The impact of immigration on the size of government: Empirical evidence from Danish municipalitiesThis study examines whether the influx of immigrants of non-Western origin in Danish municipalities in the period from 1995 to 2001 affected the size of public spending. In the paper three measures of public expenditure are examined. The resulting regression estimates do not support those scholars who propose/predict a negative link between government spending and immigration in Western welfare states. On the contrary, an increase in the share of non-Western immigrants led to a small but significant increase in income tax payments.The impact of immigration on election outcomes in Danish municipalitiesIn this paper we study the effects of changes in the share of immigrants of non-Western origin in Danish municipalities on the support for different political parties in the period from 1989 to 2001. Regression estimations show that anti-immigration parties gained support as a reaction to a larger immigrant share, but so did also a pro-immigration party on the left. Our results point to that Danish citizens voice their displeasure over immigration within their neighborhoods; nevertheless, we do not find indications of a weakening of support for the welfare state as such, as predicted by several authors.

The Impact of Immigration on the Size of Government : Empirical Evidence from Danish Municipalities
- 2011
-
Ingår i: Scandinavian Journal of Economics. - 0347-0520. ; 113:1, s. 74-92

Tidskriftsartikel (refereegranskat)abstract
- Several studies have reported a negative relationship between ethnic heterogeneity and the size of the public sector. One problem with this literature is that ethnic composition is hardly exogenous, which obstructs attempts to reveal causal mechanisms. This paper explores the impact of changes in ethnic heterogeneity in Danish municipalities from 1995 through 2001, a period marked by an unprecedented influx of refugees. A state-sponsored placement policy restricted their choice of residence and required local governments to accept them as citizens. The analysis of the impact of this influx has not revealed any support for the claim of a decline in public sector size.

The significance of immigration for public finances in Denmark
- 2011
-
Rapport (övrigt vetenskapligt)abstract
- This paper studies the economic consequences of immigration for public finances in Denmark. Using new figures for the period 2004-2008, net transfers are calculated, and presented as an extension to the figures that already existed for the period 1991-2001. The net transfers are calculated from a marginal perspective, which means that the included public expenditures and incomes can be traced to each individual person in our sample. The study is therefore suited for analyzing the economic consequences if more/less people immigrate. A consistent pattern to emerge throughout is that net transfers from Western first- and second-generation immigrants to state funds are positive, while those from non-Western first- and second-generation immigrants are negative. The new calculations show that net transfers from non-Western first- and second-generation immigrants fell from DKK -12.8 billion in 2004 to DKK -9.1 billion in 2008, largely due to the improved employment situation in Denmark. The results also show, however, that the composition chosen of the group of non-Western immigrants has a significant effect on the calculation of net transfers, in that these transfers are reduced to DKK -2.2 billion if refugees are excluded from this group.

Using 'Shares' vs. 'Log of Shares' in Fixed-Effect Estimations
- 2011
-
Ingår i: Journal of Economics and Econometrics. - Brussels : EERI Economics and Econometrics Research Institute. - ISSN 2032-9652 E-ISSN 2032-9660. ; 54:1, s. 1-7

Tidskriftsartikel (refereegranskat)abstract
- This paper looks at potential implications emerging from including "shares" as a control variable in fixed effect estimations. By shares we refer to the ratio of a sum of units over another, such as the share of immigrants in a city or school. As will be shown in this paper, alogarithmic transformation of shares has methodological merits compared to the use of shares defined as mere ratios.
