The adaptiveness in stock markets: testing the stylized facts in the DAX 30

© 2017, Springer-Verlag Berlin Heidelberg. By testing a simple asset pricing model of heterogeneous agents to characterize the power-law behavior of the DAX 30 from 1975 to 2007, we provide supporting evidence on empirical findings that investors and fund managers use combinations of fixed and switching strategies based on fundamental and technical analysis when making investment decisions. A mechanism analysis based on the calibrated model provides a behavioral insight into the explanatory power of rational switching behavior of investors on the volatility clustering and long range dependence in return volatility

Estimation of Financial Agent-Based Models with Simulated Maximum Likelihood

This paper proposes a general computational framework for empirical estimation of financial agent based models, for which criterion functions do not have known analytical form. For this purpose, we adapt a nonparametric simulated maximum likelihood estimation based on kernel methods. Employing one of the most widely analysed heterogeneous agent models in the literature developed by Brock and Hommes (1998), we extensively test properties of the proposed estimator and its ability to recover parameters consistently and efficiently using simulations. Key empirical findings point us to the statistical insignificance of the switching coefficient but markedly significant belief parameters defining heterogeneous trading regimes with superiority of trend-following over contrarian strategies. In addition, we document slight proportional dominance of fundamentalists over trend following chartists in main world markets

Excess Volatility and Speculative Bubbles in the Canadian Dollar: Real of Imagined?

Greater intervention by the public sector is often proposed as a solution to the increased speculation and excessive price volatility through to characterize today's competitive world financial system. However, before any ambitious policy responses can be contemplated, the question whether asset prices are in fact subject to excess volatility needs to be answered. This paper tries to answer the question by using the Canadian dollar as representative asset and testing for excess volatility and speculative bubbles. In the main, the empirical sections of the paper provide little support for the execess volatility argument and the subsequent need for government interventionPRICES;FINANCIAL MARKET
