SPECIFYING AND TESTING OUTPUT AND PRICING STRUCTURES OF ALTERNATIVE MACROECONOMIC MODELS
提出一个框架，用于在替代性宏观经济模型间进行选择。通过设定包含进口品、出口品和非贸易品的三部门模型，该框架将凯恩斯单部门不完全替代模型和两部门依赖经济模型作为特例，并建议两阶段检验程序让数据决定最合适的模型，以阿根廷、巴西和墨西哥为例说明。
ABSTRACT This paper puts forward a framework for choosing between alternative macroeconomic models. It is shown that a three‐sector model with importables, exportables and non‐traded goods can be specified so as to encompass both the Keynesian one‐sector imperfect substitutes model and the two‐sector dependent economy model with traded and non‐traded goods as special cases. A two‐stage test procedure is suggested in order to let the data determine which of these alternative models is the most appropriate. The use of this procedure is illustrated for the case of Argentina, Brazil and Mexico.
