The purpose of this paper to identify and analyze the effects of existing trade networks on bilateral trade volumes in the Western Hemisphere using two empirical specifications of the gravity model of international trade. The evidence suggests the trade behavior within the Western Hemisphere is highly influenced by relationships resulting from different types of linkages (i.e., networks). These...

Current research on antidumping suggests a number of channels through which antidumping affects the volume of world trade. This paper uses a structural approach to the gravity model framework to evaluate these hypotheses using data on trade volume over the period 1960-2001. We conclude that the volume and welfare effects have been negative, but quite modest. JEL classification: C230; F14; F15

Three different global gravity model solutions have been released by the European GOCE Gravity Consortium: a direct solution, a time-wise solution and a space-wise solution. To date, two releases of each solution have been issued. Each of these solutions has specific positives and weaknesses. This paper shows and analyzes the differences between each solution in Central Europe by means of compa...

We investigate brane world models in higher-derivative gravity theories where the gravitational Lagrangian is an arbitrary function of the Ricci scalar. Making use of the conformal equivalence of such gravity models and Einstein-Hilbert gravity with a scalar field, we deduce the main features of higher-derivative gravity brane worlds. We solve for a gravity model that has corrections quadratic ...

The metropolitan area is an important carrier to enhance regional innovation capacity and soft power. There are always some imbalances in the dynamic process of regional development, for example, the metropolitan “lamp shadow” phenomenon. In this paper, we take the first nature and the second nature as research perspectives and construct a theoretical framework to analyze the “lamp shadow” phen...

We model multistage competition in supply chains by a sequential game theoretical network. show the uniqueness of equilibrium for series parallel networks and provide linear time algorithm to compute equilibrium. study impact network structure on firms' payoffs, total trade flow, overall social welfare.

Market Structure and the Demand for Free Trade ABSTRACT We explore the interplay of market structure and government trade policy in the context of a heterogenous goods duopoly model (allowing for goods to be substitutes or complements) wherein governments simultaneously and noncooperatively choose whether or not to provide subsidies for their firms and then firms noncooperatively choose output ...

T his paper investigates the gain of bilateral trade between China and U.S. in manufacturing sectors when both countries play a role in asymmetric (biased) growth of  international trade. Our model includes a special case of Biased Growth Theory in international trade. We collected labor productivity, export and import data by using classification of manufacturing industries, for U.S...

Model complexity is key concern to any artificial learning system due its critical impact on generalization. However, EC research has only focused phenotype structural complexity for static problems. For sequential decision tasks, phenotypes that are very similar in structure, can produce radically different behaviors, and the trade-off between fitness and complexity in this context is not clea...
