VOLUNTARY IMPORT EXPANSION AND DIRECT INVESTMENT*

This paper analyses the welfare effects of a market‐share Voluntary Import Expansion (VIE) in the presence of foreign direct investment utilizing a duality approach. Introducing the cost burden of VIE explicitly, this paper considers the conditions under which a market‐share VIE is voluntary to the importing country. It is shown that the voluntary nature of VIE depends upon the capital import, cost burden and price difference effects and that a VIE is truly voluntary if it is accompanied by direct investment. We also show the existence of a complementary relationship between VIE and direct investment in attaining a particular level of welfare.     

Structural Error Correction Models: A System Method for Linear Rational Expectations Models and an Application to an Exchange Rate Model

This paper develops a system instrumental variable method to estimate the speed of adjustment coefficient in the long-run equilibrium of structural error correction models for a class of linear rational expectations models. This method is applied to an exchange rate model with sticky prices, in which the speed of adjustment coefficient governs the half-life of the real exchange rate. Compared to single equation methods, the system method gives smaller half-life estimates with sharper standard errors.     

An Unequal Spatial Structure of Location and Price with Consumer Density*

This paper incorporates the interdependent relationship of firms and the increasing consumer density into a framework of spatial equilibrium analysis, and studies the location of firms and the price system on a plane market. As consumer density increases, symmetric equilibrium is established initially for the first- and the second-round entry of firms, but this equilibrium becomes unequal later for the third and the fourth rounds. This fact means that in spatial equilibrium, even if all firms sell identical goods on a plane market, mill prices and market area sizes will differ.
