Abstract

Extending US samples, this paper re-examines the classic consumption-based capital asset pricing model (CCAPM) by the generalized method of moments (GMM). Our re-exploration using US three industry returns and different price deflators supplies the following evidence. First, 1) regarding the CCAPM using the US consumption for nondurable goods and the deflator of total personal consumption expenditures (PCEs), the discount rate and risk aversion parameters show plausible values; and according to the J-tests, our above first CCAPM is generally supported. Second, 2) as for the CCAPM with the US consumption for nondurable goods and services and the deflator of total PCEs, both discount rate and risk aversion parameters generally exhibit plausible values and our J-tests show that our above second CCAPM is highly supported. Third, 3) as for the CCAPM using the US consumption for nondurable goods and the deflator of the PCEs for nondurable goods, both parameters of the discount rate and risk aversion are highly stable and our J-tests indicate that our above third CCAPM is highly supported. Finally, 4) as regards the CCAPM using the US consumption for nondurable goods and services and the calculated implicit deflator of the PCEs for nondurable goods and services, the parameters of the discount rate generally exhibit plausible values, while the risk aversion parameters are not so stable. However, according to the J-tests, our above fourth CCAPM is also highly supported.
