We construct a uni…ed framework to study under what conditions one of the three frequently observed organizational structures of international middle-product production may arise in equilibrium: (i) separation of upstream and downstream …firms with middle-product trade, (ii) vertical...

We develop a dynamic model of intermediate goods trade in which the pattern and the extent of intermediate goods trade are endogenous. We consider a small open economy whose …final good production employs an endogenous array of intermediate goods, from low technology (high cost) to high...

The paper examines the interactions between economic integration and population agglomeration in a middle product economy displaying neoclassical growth. There are two vertically integrated economies. Each consists of a large number of final good competitive firms operating plants in both...

We propose location-then-variety competition for a multi-product and multi-store oligopoly, in which the number of firms, the number of stores and their location, and the number of varieties are endogenously determined. We show that as compared to price-then-variety and quantity-then-variety...

We develop a discrete or finite household model with congestable local public goods where the level of provision, the number of facilities and their locations are all endogenously determined in a purely normative context. We prove the existence of an equal-treatment identical-provision second...

This paper reexamine Tiebout’s hypothesis of endogenous sorting in a competitive spatial equilibrium setup with both income and preference heterogeneity. Agents decide endogenously the number of trips to consume a travel-for congestable local public good. We show that the equilibrium...

The paper investigates a two-stage competition in a vertical di¤erentiated industry, where each …firm produces an rbitrary number of similar qualities and sells them to heterogeneous consumers. We show that, when unit costs of quality are increasing and quadratic, each …firm has an incentive...

What are the effects of increasing developing countries’ intellectual property rights protection on growth, welfare and income inequality in the global economy? To analyze this question, we develop a two-country R&D-growth model with wealth heterogeneity. We find that the North experiences...
