This paper empirically estimates a heterogeneous agents model using S&P 500 data. While previous studies on heterogeneous agents models typically resort to simulation techniques, our empirical results indicate that the market is populated with fundamentalists, chartists, and noise traders. In...

In this paper we combine the heterogeneous agent literature with the market microstructure literature in order to introduce time varying measures of price discovery based on underlying profit maximizing behavior. We set up a heterogeneous agent model with arbitrageurs and chartists, and allow...

We estimate a heterogeneous agent model on five prominent equity investment styles - value, size, profitability, investment, and momentum - and find evidence for behavioral heterogeneity in expected return formation. Our model features two groups of boundedly rational investors, fundamentalists...
