We estimate for a sample of U.S. companies an econometric model of each companies' dividend process. We use this to forecast future dividends, and thereby calculate a theoretical present value for each company. We compare this to the market price and test whether one can earn excess returns by purchasing shares which are undervalued, compared to this theoretical price. We show that portfolios of underpriced shares substantially outperform the full sample.  相似文献

In this paper, we derive a model of book-to-market value of equity based on the present value model and estimate it using panel data on individual stocks. We explicitly include in the model all the determinants of book-to-market except the firm-specific discount rate, which we capture using fixed individual effects in the panel data model. The model is particularly successful, explaining nearly 90% of the time series and cross-section variation in the ratio of book-to-market value of equity. Moreover, the estimated firm-specific fixed effects are more successful than the most recent book-to-market value of equity in forecasting subsequent returns. This is consistent with an efficient market in which book-to-market is a proxy for risk.  相似文献

We show that uncertainty about parameters of the short rate model can account for the rejections of the expectations hypothesis for the term structure of interest rates. We assume that agents employ Bayes rule to learn parameter values in the context of a model that is subject to stochastic structural breaks. We show that parameter uncertainty also implies that the verdict on the expectations hypothesis varies systematically with the term of the long bond and the particular test employed, in the same way that is found in empirical tests.  相似文献

The expectations hypothesis of the term structure has been decisively rejected in a large empirical literature that spans several decades. In this paper, using a newly constructed dataset of synthetic zero-coupon bond yields, we show that evidence against the expectations hypothesis is substantially weaker in data generated after the widespread publicity of its failure. These results are consistent with the idea that asset pricing anomalies tend to disappear once they are widely recognized.  相似文献
