Conditions of Existence of a Two Class Economy in the Kaldor and More General Models of Growth and Income Distribution
研究了在利润率和利率不同关系下，区分资本家与工人不同储蓄倾向的两阶级经济能否稳定存在，并比较了卡尔多和帕西内蒂两种储蓄函数下的存在范围。
SUMMARY The author considers the vexed question of whether it is meaningful, or logically consistent, to assume different savings propensities for profits and wages, independently of whether the savers are capitalists or workers. The author claims, however, that the analytical issues must be clarified first of all. Therefore he explores the conditions of existence of a two‐class (capitalists and workers) economy when the rate of interest i is lower than (or at most equal to) the rate of profit r, and the savings function is expressed in the general form: S = s ww + s wc P w + S c P c It is shown that, at one extreme, when S wc = S e , the savings function reduces to the one originally used by Kaldor, and, if also i = r, no equilibrium path exists. At the other extreme, when S wc = S ww , the savings function reduces to the one originally used by P asinetti and the range of existence of a two‐class economy is maximum. In between the two extremes, ranges of existence are defined in terms of inequalities involving the parameters of the system.
