The discrimination literature treats outcomes as relative. But does a differential arise because agents discriminate against others—exophobia—or because they favour their own kind—endophilia? Using a field experiment that assigned graders randomly to students' exams that did/ did not...

The use of institutional measures in empirical work is widespread, but the question of what these measures actually capture and how they are constructed is something that is not given enough attention. Institutions and their measures are therefore like a “black box of goodies”: Something...

Nationalekonomiska metoder och modeller tillämpas inom de mest skiftande områden som kriminalitet, barnuppfostran och drogmissbruk. Ett skäl till ämnets framgång är dess användning av matematik. Nationalekonomins formalisering synes dock även ha inneburit insnävade beteendeantaganden...

The difference between accommodated evidence (i.e. when evidence is known first and a hypothesis is proposed to explain and fit the observations) and predicted evidence (i.e., when evidence verifies the prediction of a hypothesis formulated before observing the evidence) is investigated....

This paper follows the theory of optimal taxation and the goal is to identify a tax/benefit design that maximizes social welfare. A two stage process is proposed where the individuals preferred choice of leisure and consumption is solved in the first stage, and the second stage identifies the...

Distance-based regression is a prediction method consisting of two steps: from distances between observations we obtain latent variables which, in turn, are the regressors in an ordinary least squares linear model. Distances are computed from actually observed predictors by means of a suitable...

Time heterogeneity, or the fact that subjects are measured at different times, occurs frequently in non-experimental situations. For time heterogeneous data having error components regression structure it is demonstrated that under customary normality assumptions there is no estimation method...

The paper analyses academic journal quality and impact using quality weighted citations that are based on the widely-used Thomson Reuters ISI Web of Science citations database (ISI). A recently developed Index of Citations Quality (ICQ), based on quality weighted citations, is used to analyse...

This paper demonstrates that unit root tests can suffer from inflated Type I error rates when data are cointegrated. Results from Monte Carlo simulations show that three commonly used unit root tests – the ADF, Phillips-Perron, and DF-GLS tests – frequently overreject the true null of a unit...

Experts possess knowledge and information that are not publicly available. The paper is con¬cerned with forecasting academic journal quality and research impact using a survey of inter¬na¬tion¬al experts from a national project on ranking academic finance journals in Taiwan. A...
