The fixed factor proportions model of production and trade

概要

This paper reviews the model of production and trade with fixed input coefficientsand more than ａ single factor of production, ａ model that may be underappreciated. This "fixed factor proportions" model is a bridge between the constant cost model with one input and the factor proportions model with two inputs. The direction of tradeis determined by differences in technology or differences in factor abundance. With the same number of factors and products, the factor proportions theorems are identical. The paper also presents assumptions sufficient for tractable comparative staticresults with different numbers of factors and products.
