The demographic cycle and optimal schooling choices

A model is developed that enables the authors to estimate the effects of demographic cycles on both earnings and schooling. The model is tested using data from the 1991 Korean Occupational Wage Survey. The results indicate that cohorts following large birth cohorts in the cycle choose relatively less formal schooling compared to pre-peak cohorts, and that post-peak cohorts also have lower incomes. This result concerning South Korea is consistent with findings from previous studies concerning the United States.     

THE EFFECTS OF VERTICAL MARKETS ON TRADE POLICY REFORM

Typically, analysis of trade liberalization ignores the impactthat intermediate stages in the production and distributionsystem may have on the pass-through of changes in tariffs tofinal goods' prices. Using a model of a multi-stage system,this paper shows that both the number of vertical stages andthe degree of imperfect competition at any specific stage canaffect the degree of tariff pass-through. Simulation of themodel with respect to recent changes in the European Union bananaregime suggests that ignoring vertical market structure is likelyto over-estimate the benefits to consumers of trade liberalization.
