This paper examines two competing explanations for workers' absenteeism, the shirking hypothesis and the adjustment-to-equilibrium hypothesis. Data on German workers for 1985-88 from the German SocioEconomic Panel are used in order to estimate the determinants of workers' absenteeism. The results indicate that firm size matters after wage effects are controlled for. This evidence supports the shirking hypothesis.
This paper is concerned with the problems of posterior simulation and model choice for Poisson panel data models with multiple random effects. Efficient algorithms based on Markov chain Monte Carlo methods for sampling the posterior distribution are developed. A new parameterization of the random effects and fixed effects is proposed and compared with a parameterization in common use, and computation of marginal likelihoods and Bayes factors via Chib’s (1995) method is also considered. The methods are illustrated with two real data applications involving large samples and multiple random effects.
Michael Porter and others have recently argued that suitable environmental regulations are likely to induce cost-reducing innovations. We analyze under which conditions such arguments might be consistent with microeconomic analysis, and under which additional conditions the firms' benefits might exceed the costs. It turns out that this requires fairly specific conditions.
Recently, the 'new economic geography' literature has developed as a theory of the emergence of large agglomerations which relies on increasing returns to scale and transportation costs. This literature builds on diverse intellectual traditions. It combines the insights of traditional regional science with those of modern trade theory and thus attempts to provide an integrative approach to interregional and international trade. The paper surveys this literature and discusses its relation to earlier approaches to similar topics.
