Dual labor market hypothesis and long-run income distribution

We construct a dynamic model of dual labor market, incorporating firm investment behavior and household investment behavior on education. Education enhances the trainability of individuals and thus provides qualifications for entry into the primary market. Two specifications of the model, differing in the nature of the new entrants' market, are presented; one admitting competitive adjustment in the scarcity premium of qualified entrants, while the other, a generalization of Thurow's job competition model, allocates employment through rationing. We obtain sharply different long-run determinants of income distribution between these alternative models. The result extends and qualifies existing interpretations on the schooling paradox observed in the U.S.     

Migration Turnarounds and Schedule Changes in Japan, Sweden and Canada

Little progress has been made in convincingly identifying the common determinants of the simultaneous migration turnarounds observed in almost all advanced countries. It is likely, however, that the turnarounds occurred in close relation to changes in the age patterns of the migration rates (or migration schedules). This paper examines the main causes of migration schedule changes by applying a model migration schedule to inter-regional migration data from Japan, Sweden and Canada. The general decline of overall mobility defined by the gross migraproduction rate is common to the three countries. It was clarified that young adults' peak migration rate played a prominent role in changing migration schedules during the decades of the migration turnarounds.     

Using DEA to evaluate the state of society as measured by multiple social indicators

This paper presents an approach for discussing the state of society, which is measured by multiple social indicators, using data envelopment analysis (DEA). Replacing inputs and outputs in DEA with negative and positive social indicators respectively, we analyze the desirability of living in the 47 prefectures of Japan. This is also a proposal for the potential use of DEA in multi-dimensional evaluation analysis other than the standard DEA efficiency analysis. The results using eight social indicators identify 26 DEA desirable prefectures out of the 47 and present other useful knowledge and information. It is concluded that DEA, which can avoid uniform evaluation by an a priori weighting system, provides availability as a comprehensive evaluation tool different from traditional ones.
