This paper focuses on Indo-Iranian merchandise trade for a period of 30 years from1980-81 to 2009-10. The study is based on econometric modeling comprising 3 versions of the RWM model and alternative forms and specification of regression functions. RWM model(s) evaluates the stationary nature of time series data relating to GNP, Exports, Imports and total merchandise Indo-Iranian trade. Dickey-...

This paper investigates the impact of the US and China’s foreign aids to Africa on trade flows between donor and recipient countries. Evidence from the gravity model estimates reveals that the two donors’ exports are strengthened by their aids to African partners. Interestingly, China’s aid shows a positive effect on its total volume of trade and imports from Africa, while the aid from the US e...

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...

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...
