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.     

INTERPRETING CHANGES IN THE ECONOMIC STATUS OF THE ELDERLY, 1949-1979

This paper analyzes changes in the economic well-being of the elderly using data from the Decennial Censuses of 1950 through 1980. We find that the economic status of each elderly cohort is higher on average than that of the preceding cohort. Certain events associated with age–retirement for both men and women and widowhood for women–are associated with declining incomes. Controlling for sex, labor force participation, and marital status, however, the economic well-being of elderly cohorts generally increases with age.     

Market Access and WTO Border Tax Adjustments for Environmental Excise Taxes under Imperfect Competition

The literature identifies linkages between domestic environmental policies and trade, the treatment of imports being an important issue in administration of domestic environmental excise taxes. With the aim of ensuring foreign exporters do not attain a competitive advantage, border tax adjustments are used. Since most environmental excise taxes apply to intermediate goods, the relevant border tax adjustment applies to final imported goods. However, when both intermediate and final goods markets are oligopolistic, border tax adjustments may be non‐neutral. Moreover, even if market access is unchanged, border tax adjustments can still lead to redistribution of profits between domestic and foreign firms.
