Management for a Variety of Environmental Pollution and North-South Trade

A simple static model incorporating a variety of environmental pollution is developed. An autarky model shows that a developing country regulates fewer types of pollution by income-induced environmental policy. As income grows, the types of regulated pollution increase and also introduced regulations become tougher.Then the model incorporates international trade between a developed country and a developing country. The model gives a new interpretation for the pollution haven hypothesis. Some types of pollution abated with inefficient technology are emitted more in a developing country but other types necessarily increase in a developed country in order to meet the trade balance.

Cost Reduction Effects of "pseudo FTAs" in Asia -Application of a price model based on a multilateral I/O table-

This paper examines the repercussion effects on the production cost of industries in Asian countries when some countries eliminate tariffs and import commodity taxes on all imports. This kind of analysis is related in some sense to that measuring the effects of FTAs on economies, and thus may be considered as an analysis of “pseudo FTAs.” Examining a number of combinations of “pseudo FTAs” between China, Japan, and ASEAN, it is found that the case of China plus Japan plus ASEAN is the most effective “pseudo FTA” of the combinations in terms of production cost reduction. The method is a form of price model based on the Asian International Input-Output Table. Almost no studies on price models related to multilateral I/O tables have been implemented thus far.

On the variety of Mexico's export goods

This paper examines the evolution of the variety of Mexico’s export goods using disaggregated trade data. Both the econometric estimation analyses using the raw data and the one using an improved version of Feenstra and Kee's (2004, 2007) methodology proposed in this paper show that NAFTA membership does not enhance the variety of Mexico's export goods. This finding contrasts with NAFTA's positive association with the increase in export variety found in the literature.
