We explore the relationship between attractiveness and risk taking in chess. We use a large international panel dataset on 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...

This paper looks at potential implications emerging from including shares as a control variable in fixed effect estimations. By shares I 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, a logarithmic...

We examine rational learning among expert chess players and how they update their beliefs in repeated games with the same opponent. We present a model that explains how equilibrium play is affected when players change their choice of strategy when receiving additional information from each...

The tendency to underestimate the future value of a variable growing at a constant rate, an example of exponential growth bias, has been linked to household financial decision making. We show that exponential growth bias and standard measures of financial literacy are negatively correlated in a...

Sweden has made its labour market more open for labour immigration since the mid1990s: becoming member of the common labour market of EES/EU in 1994, no transitional rules introduced at the enlargement of European Union in 2004 and 2007, and opening up for labour migration from non-EES/EU...

This study looks at the effects of participating in active labour market policy programs for persons with work disabilities. More in detail, it draws attention to the importance of taking into account the timing of when a work disability has been registered for persons attending ALMP programs....

One of the services provided at the Swedish Public Employment Services is job coaching. Since 2012, that service has been organized according to a voucher-based choice system. In 2013, a performance indicator of job coaching providers was made available at an online website. This study examines...

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...

Recent studies point to a positive correlation between ethnic heterogeneity due to immigration and the propensity of opting out from public schools for private alternatives. However, immigration across regions is hardly exogenous, which obstructs attempts to reveal causal mechanisms. This paper...

The 2D:4D digit ratio, the ratio of the length of the 2nd digit to the length of the 4th digit, is often considered a proxy for testosterone exposure in utero. A recent study by Nicolaou et al. (2018) reported an association between the lefthand 2D:4D and self-employment (in a sample of about...
