The concept of extended Euler homogeneity of potential fields is examined with respect to all variables of length dimension in their analytical expressions. This reveals the possible existence of positive degrees of homogeneity or corresponding negative structural indices considered as extensions of the Thompson’s structural indices in Euler deconvolution. This approach is implemented for a con...

T he United States, along with almost every other country in the world, maintains significant restrictions on the movement of goods across international borders. Although the recent Uruguay round of the General Agreement on Tariffs and Trade (GATT) resulted in a general lowering of tariffs and a broadening of goods and countries covered by the agreement, free trade remains elusive. Strong growt...

Do conflicts among naval powers hurt international trade? In theory the commercially relevant aspects of aggressive naval power can either thwart trade (through blockades, embargoes, commerce raiding, and guerre de course strategies) or facilitate trade (through control of trade routes and protection of shipping). Thus the question must be empirically addressed. Using a panel gravity model, we ...

The Box-Wilson central composite design (CCD) based on response surface methodology (RSM) was used for ethanol fermentation using very high gravity (VHG) finger millet hydrolysate. Optimized process variables were namely, concentrations of yeast extract, magnesium sulphate and pH of the medium. High gravity mashes (>300 g dissolved solids per liter) were prepared by a thermo-stable α-amylase, f...

Abstract This article is an empirical attempt to explore the relationship between sanctions (financial and non-financial), oil price shocks and Iran-Russian bilateral trade flows over the period 1991–2014. In contrast to earlier studies in which a gravity model has been estimated through a panel data approach, in this paper the authors apply a gravity model for only two countries and do the es...

We synthesize the financial crisis contagion literature through the gravity model from physics and test the hypothesis that the severity of contagion relates positively to trade and financial linkages but negatively to psychic distance between countries, when macroeconomic fundamentals and institutional factors are controlled. The psychic distance variable, a behavioral predictor constructed al...
