A BSTRACT According to the Heckscher-Ohlin-Vanek theorem, the net exports of a region are determined by relative abundance of the immobile factors of production. Empirical tests of this theory, usually at a high level of aggregation, have frequently not supported it. We find, instead, that data on interstate trade in wood products within the United States are in strong agreement with the theore...

BACKGROUND In ToxCast™ Phase I, the U.S. EPA commissioned screening of 320 pesticides, herbicides, fungicides, and other chemicals in a series of high-throughput assays. The agency also developed a toxicological prioritization tool, ToxPi, to facilitate using ToxCast™ assays to predict biological function. OBJECTIVES We asked whether top-scoring PPARγ activators identified in ToxCast™ Phase I...

It is hard to believe that factor endowments theory could offer an adequate explanation of international trade patterns. While the theory adequately predicts Saudi Arabian oil exports, it hardly seems appropriate for explaining the revolutionary impact of new technologies on world trade. Yet to take this position is to misunderstand the thrust of recent empirical research in international trade...

This study sets out to capture the effect that environmental policy has on trade and specifically then examining the notion that lax environmental regulations will constitute a basis of comparative advantage, causing the least regulated jurisdictions to specialize in polluting industries. This is done partly by a survey of the empirical literature on this subject and partly by performing an eco...

The impact of international trade on domestic growth is revisited in a model with dynamic externalities and static increasing returns to scale. The model embraces features of both classical and new growth and trade theories, allows for learning by doing, and integrates several strains of thought in a general equilibrium with two regions. In contrast to previous work, the model shows that intern...

The entity of interstitial plasma cell pneumonia due to Pneumocystis carinii has received increasing attention during the past 10 years. Extensive studies and reviews concerning this problem, its epidemiology and pathogenesis (Ahvenainen, 1957; Bachmann, 1954; Cahalane, 1962; Jirovec, 1 960a and b; Muller and Vietor, 1957), its clinical course and picture (Berdnikoff, 1959; Dvorak and Jirovec, ...

We report a case of a 45-year-old woman who presented with vomiting & severe fatigue. On routine examination show iron deficiency anemia Gastroscopy revealed a large polyp in the antral region causing intermittent gastric outlet obstruction. Histopathologic examination revealed an inflammatory fibroid polyp (known also as Vanek’s tumour). 1 Background: Gastric polyps are usually found incidenta...

The Heckscher-Ohlin-Vanek (HOV) theorem predicts whether a country will be a net exporter of services of a certain factor and the volume of the factor content of trade given the country's and the world's factor endowment information. Recent empirical work has documented that the measured factor content of trade is too small compared to the theoretical prediction and named this special pattern o...
