Complementarity And Increasing Returns In Intermediate Inputs

Conventional analysis in the trade-industrial-organization literature suggests that, when a country has some market power over an imported good, some small level of protection must be welfare improving. This is essentially a terms-of-trade argument that is reinforced if the imported goods are substitutes for domestic goods produced with increasing returns to scale, goods that are initially underproduced in free-trade equilibrium. This paper notes that this result may not hold when (1) the imports are intermediates used in a domestic increasing-returns industry, and/or (2) the intermediates are complements for domestic inputs produced with increasing returns. We then demonstrate such an outcome with respect to Mexican protection against imported auto parts using an applied general-equilibrium model of the North American auto industry.

In a general equilibrium model where firms are heterogeneous in terms of productivity, we introduce differentiated goods in production that are not perfect substitutes, as well as intermediate inputs needed to produce those goods. We show that an increase in either the complementarity of differentiated goods or the share of intermediate inputs in gross output, significantly increases the negative effect of entry costs on total factor productivity (TFP) and output per worker. We also find that the effect of complementarity is quantitatively stronger. If we assume an empirically plausible value for the elasticity of substitution between differentiated goods, then the model considerably improves its ability to reproduce the observed negative relationship between entry costs and TFP or output per worker.

In this collection of 17 articles, top scholars synthesize and analyze scholarship on this widely used tool of policy analysis, setting forth its accomplishments, difficulties, and means of implementation. Though CGE modeling does not play a prominent role in top US graduate schools, it is employed universally in the development of economic policy. This collection is particularly important because it presents a history of modeling applications and examines competing points of view. Presents coherent summaries of CGE theories that inform major model types Covers the construction of CGE databases, model solving, and computer-assisted interpretation of results Shows how CGE modeling has made a contribution to economic policy

Economic Theory, Dynamics, and Markets. The collection of essays in honor of Ryuzo Sato, written by his colleagues and students, covers the many fields of economic theory and policy to which he has contributed. The first section pays tribute to his contributions to mathematical economics and economic theory. Ryuzo Sato is known for his work in growth theory and technical progress, and the second section has a number of papers on macroeconomics and dynamics. The third section has a number of papers on financial markets and their functioning in Japan and the United States. The next section examines various aspects of the economics of firms and industry. Ryuzo Sato has been very involved in analyzing the economic and business relations between Japan and the United States, and the last section is devoted to comparative analysis of economic systems.

This paper investigates Allyn Young's two important doctrines concerning the division of labor and roundabout production: Apart from advancement in the state of knowledge, the progressive division of labor, which can take place within a given population, brings about the adoption of more specialized, differentiated intermediate goods in the production process; the level of division of labor and the extent of the market depend on each other. Using a general equilibrium model with increasing returns to specialization, economies of complementarity between intermediate goods, and transaction costs, we demonstrate that the level of division of labor and the number of intermediate goods increase concurrently as transaction conditions are improved.

The dark side of preferential trade agreements, Rules of Origin (RoO) are used to determine the eligibility of goods to preferential treatment. Ostensibly meant to prevent the trans-shipment of imported products across Free Trade Agreement borders after superficial screwdriver assembly, they act in reality as complex and opaque trade barriers. This book provides evidence strongly suggesting that they do so by intent rather than accidentally---in other words, that RoOs are policy.Part one draws insights about the effects of RoOs on cross-border trade and outsourcing from recent economic theory. Part two reviews the evidence on RoOs in preferential agreements around the world, putting together the most comprehensive dataset on RoOs to date. Part three explores their "political economy"---how special interests have shaped them and continue to do so. Part four provides econometric evidence on their costs for exporters and consequent effects on trade flows. Finally, partfive explores how they affect trade in the developing world where they spread rapidly and have the potential to do most harm.Beyond the collection of new evidence and its interpretation in light of recent theory, the book's overall message for the policy community is that RoOs are a potentially powerful and new barrier to trade. Rather than being relegated to closed-door technical meetings, their design should hold center-stage in trade negotiations.

The core of classical economic analysis represented by William Petty and Adam Smith concentrated on the field of development economics. This classical footing of the study of development is different from the neoclassical perspective in two important respects: (a) it focuses on division of labor as the driving force of development, and (b) it emphasizes the role of the market (the “invisible hand”) in exploiting productivity gains that are derived from division of labor. However these aspects have received little attention in the body of literature that represents the modern field of development economics — which largely represents the neoclassical application of marginalism. A notable exception is research that utilizes inframarginal analysis of individuals' networking decisions in an attempt to formalize the classical mechanisms that drive division of labor. This book is a first attempt to collect relevant key contributions and is intended for active researchers in the field of development economics.
