An iterated GMM procedure for estimating the Campbell–Cochrane habit formation model, with an application to Danish Stock and bond returns

Abstract

We suggest an iterated GMM approach to estimate and test the consumption based habit persistence model of Campbell and Cochrane, and we apply the approach on annual and quarterly Danish stock and bond returns. For comparative purposes we also estimate and test the standard constant relative risk-aversion (CRRA) model. In addition, we compare the pricing errors of the different models using Hansen and Jagannathan's specification error measure. The main result is that for Denmark the Campbell-Cochrane model does not seem to perform markedly better than the CRRA model. For the long annual sample period covering more than 80 years there is absolutely no evidence of superior performance of the Campbell-Cochrane model. For the shorter and more recent quarterly data over a 20-30 year period, there is some evidence of counter-cyclical time-variation in the degree of risk-aversion, in accordance with the Campbell-Cochrane model, but the model does not produce lower pricing errors or more plausible parameter estimates than the CRRA model.

Discrete-Time AffineℚTerm Structure Models with Generalized Market Prices of Risk

“…CC, Wachter, and Verdelhan calibrated their models to selected sets of moments. Others have used G M M methods to estimate equilibrium models off Euler equations; see, for example, Fuhrer (2000) and Engsted and Moller (2008) for habit-based models and Bansal, Kiku, and Yaron (2009) and Constantinides and Ghosh (2008) for models with long-run risks (LRR) in consumption growth. Our framework renders full-information maximum likelihood (ML) feasible for these (and other) equilibrium asset pricing models.…”

The GEL estimates resolve the risk-free rate puzzle in Japan

“…The difficulty relates to puzzles in the U.S. What the differences are between the financial markets in the U.S. and those in Japan is left to further research. Furthermore, as Hyde et al (2005) and Engsted and Møller (2010) show, CCAPMs possibly have some explanatory power for European financial markets. Whether French, German, and Danish data, which the above authors analyzed, resolve the risk-free rate puzzle is an open question.…”

“…As Stock and Wright (2000) report, the analysis of conventional GMM procedures of CCAPM and linear instrumental variable regression breaks down when some or all of the parameters are weakly identified (see also Stock et al (2002) for details). Therefore, more and more econometricians who are interested in CCAPM have given up applying GMM to macroeconomic time series data in the U.S., although some economists still use GMM to test the performance of CCAPM for time series data in several European countries (for examples, see Hyde et al (2005) and Engsted and Møller (2010), who report that CCAPMs have some explanatory power for European financial markets).…”

Equity Premium Puzzle: A Finnish Review

“…Engsted, Mammen and Tanggaard (2001) studied Danish equity premium for varying investment horizons. Engsted and Moller (2010) studied the important features of Danish equity and bond markets whilst estimating standard CRRA utility and Campbell and Cochrane (1999) habit formation models. The latter study concludes that habit formation model with consumption surplus ratio doesn't perform markedly better than CRRA utility.…”
