aAll elasticities are positive. If we draw this derived demand in {z , t }-space, then (17) shows that an increase in scale, capital abundance, or the world price of dirty goods shifts 所有弹性是正面的。 如果我们画这获得的需求{z, t} -空间,则(17)表示,在标度、资本丰盈或者肮脏的物品...

ait is only a matter of style whether or not formulate are expressde in terms of elasticities of demand and supply,or in terms of ordinary derivatives.To speak of an \"elasticities approach\" to the balance of payments is therefore to speak no sense at all. However,behind the nonsensical...
Between broad commodity groups such an assumption (want independence) has becme increasingly accepted and in fact under the label of separability has formed the basis for a family of demand models that are increasingly used to estimate demand elasticities for broad commodity groups (the linear ...
The high price elasticities of demand for many food items stress the importance of food price changes for households, and their reactions should be taken into account in the development of comprehensive agricultural and food policies in Pakistan.Aziz...
The paper estimates the long-run elasticities of import demand in Jordan over the period 1980-2004. The Engle-Granger test of co-integration, fails to find favor of a long-run relationship among variables associated with an import demand. Furthermore, the recently prescribed Stock-Watson Dynamic...

An Empirical Comparison of “Frisch” and “Time Series” Demand price Elasticities for individual Commodities In a classical article in 1959, Ragnar Frisch [8] developed a procedure, which, under the assumption of want independence 1 and given commodity budget sha... JB Goodwin,Jon A. Brandt ...
From an extension of the Imperfect Substitutes Model, elaborated by Goldstein and Khan (1978) , the Error Correction Model (ECM) was used to determine the short- and long-term elasticities. The results show that in the trade with these blocks of countries, commodities are more sensitive to ...
