Norm Bounds and a Homographic Approximation for the Wage-Profit Curve
註釋This paper provides lower and upper norm bounds for the wage-profit curve in linear single-product systems. Thus, it also constructs an algebraically simple (i.e. homographic) and empirically powerful approximation to that curve. The results finally suggest that actual economies tend to behave as 'corn-tractor' systems with respect to the shape of the wage-profit curve and, at the same time, behave as three-industry systems with respect to the shape of the production price-profit rate curves.
