An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit...

(Approximation by Moving Equilibrium). The analysis of multivariate dynamical models can sometimes be considerably simplified by the assumption that one or several variables move infinitely fast to their equilibrium values. The method is known as the 'moving equilibrium method'. Various...

Wage formation is often analyzed by assuming that wage differentials reflect productivity differentials intrinsic to the workers, like differences in skill or qualification. Observed industry and firm effects on wages suggests, however, that wage differentials may result from causes rather...

This paper develops a theory of stagflation, based on turnover-efficiency-wage theory. In these theories, wages are forward-looking, i.e., set to keep incumbents with the firm. The employed workers apply for better jobs and compete with unemployed applicants. An employed applicant is, however,...
