Numerous models are proposed to model international trade and promote it. Vanek, instead of designing a trade pattern based on the production, introduced a pattern based on the factor content of trade. In the present study, apart from the Heckscher-Ohlin-Vanek (HOV) theorem, we attempt to determine the factor content of Iran's trade without factor price equalization by using internal input-outp...

Environmental regulation is an effective tool to control environmental problems caused by foreign trade. Research conclusions are inconsistent on the relationship between regulations and exports. Based Heckscher-Ohlin-Vanek model, this paper provides empirical analysis for examination effect of manufacturing exports, adopting panel data 16 sectors from China’s during 2005-2015. Material capital...

There are two principal theories of why countries trade: comparative advantage and increasing returns to scale. Yet there is no empirical work that assesses the relative importance of these two theories in acc...

Do scale economies contribute to our understanding of international trade? Do international trade flows encode information about the extent of scale economies? To answer these questions we examine the large class of general equilibrium theories that imply Helpman-Krugman variants of the Vanek factor content prediction. Using an ambitious database on output, trade flows, and factor endowments, w...

Vanek’s tumor is a rare benign inflammatory fibroid polyp like localized lesions originating in the submucosa of the gastrointestinal tract. Intussusceptions due to inflammatory fibroid polyps are uncommon; moreover, ileo-ileal Intussusception presenting as subacute small bowel obstruction has rarely been reported. We report a 49-year-old man who came with complaints of indigestion, flatulence,...

The relationship between trade liberalisation and the environment has been the subject of a growing body of literature in recent years. As can be seen from the differing assessment of instrument types for environmental protection, one of the important factors for the relationship between environmental protection and economic competitiveness are regulatory stringency and efficiency. This concern...

G2A (from G2 accumulation) is a G-protein-coupled receptor (GPCR) that regulates the cell cycle, proliferation, oncogenesis, and immunity. G2A shares significant homology with three GPCRs including ovarian cancer GPCR (OGR1/GPR68), GPR4, and T cell death-associated gene 8 (TDAG8). Lysophosphatidylcholine (LPC) and sphingosylphosphorylcholine (SPC) were reported as ligands for G2A and GPR4 and f...

Ever since the appearance of Vanek's pioneering article in 1974, there has been a controversy about whether 'labour saving' domestic appliances actually save labour time. Vanek argued that time spent in housework had barely changed since 1926, despite the diffusion of practically every known domestic appliance over this period. Gershuny and Robinson challenge Vanek's 'constancy of housework' th...
