The Measurement and Interpretation of Real Consumption and Purchasing Power Parity for a Quantity-Constrained Economy: The Case of East and West Germany
研究了当家庭面临数量约束时，传统跨国实际消费和购买力平价测度存在的新型指数问题，利用无约束经济的需求系统信息计算距离函数和货币度量指标，并以1977年东西德消费价格和支出为例进行说明。
When households are subject to quantity constraints, conventional measures of real consumption and purchasing power parity for cross-national comparisons suffer from a new type of index number problem. Additional information on preferences taken from a demand system estimated for a similar economy without quantity constraints can be employed to calculate distance function and money-metric indexes of relative real consumption and corresponding measures of purchasing power parity. The procedure is illustrated in a comparison of East and West German consumer prices and consumption expenditures for 1977.
