The conception of aand P-receptors for catechol amines was originally based on experiments with heart and smooth muscle (Ahlquist, 1948). The present investigation deals with such receptors in glandular tissue. The starting-point was the observation that guanethidine causes a flow of saliva from the submaxillary gland which is completely abolished by dihydroergotamine in cats but only reduced b...

Innovative production is driven by creative destruction. High turnover requires frequent reallocation of capital. Banks play a major role in capital withdrawing funds from nonviable firms and redirecting credit to scale up the most productive firms. Structural parameters banking system thus affect country’s comparative advantage innovative sectors. Using Heckscher–Ohlin model with banks, this p...

Rethinking the foundations of Heckscher–Ohlin theory when countries have different technologies, this paper shows how to make the proper adjustments for international productivity differences. The central tool is a factor conversion matrix that computes the local factor content of foreign Rybczynski effects. Factor-specific productivities are a special case of these more general linear relation...

This article recapitulates some of the trade theories reputed to be twentieth century. Here, Heckscher-Ohlin theory (with its variants), endogenous growth theory, product cycle and new were considered. review thereof, amidst others, highlight assumptions these thus present critique same theories.

We decompose the factor content of trade into Heckscher–Ohlin–Vanek trade and Ricardian trade. We measure factor content using only the United States' technology and also as Leontief advocated, using the local technology. In either case, differences in endowments are quite important in explaining the factor content of trade. If one uses raw estimated coefficients as a means of comparison, diffe...

Previous empirical tests have found that,contrary to the conclusions of the HeckscherOhlin model, the factor composition of traded goods fails to reveal relative factor abundance rankings. Using a nonparametric approach, this paper discusses the refutability of two of the assumptions of the HO model: that countries have identical homothetic preferences and identical constant returns to scale pr...
