用于因果分析与规划的新型收入不平等度量AI 解读

A new system of inequality indicators is introduced in the paper. It has been elaborated for measuring income inequalities, but can serve as inequality measures for other phenomena as well. The new indicators not only measure the degree of the inequality but are also suitable for measuring its economic motivation. Properties of the new measures, including large sample properties of their estimators, are discussed. The case of the lognormal distribution is of special…

企业利润的行业研究AI 解读

A corporate profits function is first developed in which gross profits depend positively on unlagged current dollar sales and capacity utilization rates and negatively on lagged sales. This function is tested for all two-digit manufacturing industries. It is found that the estimates differ substantially but similar results can be grouped into primarily competitive and primarily oligopolistic industries. Further testing with unit labor costs as an additional independent…

随机滞后与分项构成时间序列的参数及关系AI 解读

A model is constructed for three related time series: an inflow, a stock, and an outflow. The inflow and outflow time series are related via a truly stochastic distributed lag and the three time series are viewed as cumulations of a random number of units of randomly determined size. Among the interesting results are the serial correlations of the stock and outflow time series viewed singly and the cross and cross serial correlations between outflow in t and stock at t -1,…

This paper concerns itself with the following problem: Suppose the true production function is of the CES type with constant returns to scale. If we fit an unrestricted Cobb-Douglas production function instead, what is the nature of the bias in the estimate of the returns to scale parameter?
