On the one hand, the Stolper-Samuelson (SS) corollary of the Heckscher-Ohlin theorem predicts that both trade and FDI should take advantage of the abundance of low-skilled labour in DCs and so imply an increasing demand for domestic low skilled labour and hence decreasing within-country wage dispersion and income inequality (Wood, 1994 and 1997; for a critical view, see Milanovic, 2002). On the...

A half century of empirical work attempting to predict the factor content of trade in goods has failed to bring theory and data into congruence. Our study shows how the Heckscher-Ohlin-Vanek theory, when modified to permit technical differences, a breakdown in factor price equalization, the existence of nontraded goods, and costs of trade, is consistent with data from ten OECD countries and a r...

In this paper, we investigate the non-constant stationary solutions of a general Gause-type predator-prey system with self- and cross-diffusions subject to homogeneous Neumann boundary condition. system, are introduced in such way that prey runs away from predator, while predator moves large group preys. Firstly, establish priori estimate for positive solutions. Secondly, study non-existence re...

W hen Donald Gause and Gerald Weinberg wrote this statement,1 they were asserting that writing tests is an effective way to test requirements’ completeness and accuracy. They also suggest writing these tests when gathering, analyzing, and verifying requirements—long before those requirements are coded. They go on to say, “We can use the black box concept during requirements definition because t...
