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. and china...

Abstract T his paper explains bilateral trade patterns between South Korea and thirteen OPEC member countries over the period 1980-2014 using a gravity model. The estimation results show that the gravity equation fits the data reasonably well. We confirmed the existence of long term relationships between the bilateral trade flows and the main components of gravity model - ...

we describe a simple model that fits well with iranian economy, and extends a methodology which chary at el. (2007) demonstrated. in addition to four traditional wedges, we introduce additional trade wedge. we then evaluate the contribution of these wedges to the fluctuations in iran during last three years. because of international sanction, trading cost increases, and firms have difficulty to...

the purpose of this study is to evaluate the impact of import of technology on iranian economy. we have used multi-sectoral and multi–regional computable general equilibrium gtap model. transfer of technology from one region to another is another factor effecting productivity. trade is one of the channels that speeds the transfer of technology. the effect of a ten percent productivity shock, in...

â â â â â â â â â â â â  abstract: â  as a result of recent developments, global economic centre of gravity has slide to asia-pacific region. it is predicted that asia-pacific countries will take place at the first row in global trade and nearly a half of the total trade will intensify in this region at the year 2030. on the other hand, the region covers countries from different levels of devel...

this paper explores the capabilities of multi-objective particle swarm optimization algorithmin a simulation-optimization model for solving waste load allocation problems. the main goals are totaltreatment costs, violation of the water quality standards and equity. in this research, the water qualitysimulation model is coupled with a multi-objective optimization model, mopso. in order to derive...

 Trade liberalization is often the core attention of foreign economic strategies in developing countries. Findings in the literature confirm a significant effect of free trade on developing economies through which the economic sectors benefit from technology transfer and spillovers and increasing production capacities and input productivity leading to international competitiveness. On the other...

We examine a standard, gravity model of international commerce, augmented to include political as well as institutional influences on bilateral trade. Using annual data from 1980-2001, we estimate regression coefficients and residual dependencies using a hierarchy of models in each year. Rather than gauge the generalizability of these patterns via traditional measures of statistical significanc...
