The yield curve as a leading indicator: some practical issues
Since the 1980s, economists have argued that the slope of the yield curve-the spread between long- and short-term interest rates-is a good predictor of future economic activity. While much of the existing research has documented how consistently movements in the curve have signaled past recessions, considerably less attention has been paid to the use of the yield curve as a forecasting tool in real time. This analysis seeks to fill that gap by offering practical guidelines on how best to construct the yield curve indicator and to interpret the measure in real time.

The aggregate change in shares and the level of stock prices
The average change in shares of equity is negatively correlated with estimates of the equity premium calculated using the dividend-ratio model of Campbell and Shiller, as well as with a variant of the model written in terms of the earnings-price ratio. This correlation is consistent with corporations issuing equity when it is a relatively inexpensive source of finance and repurchasing equity when it is a relatively good investment. However, when the retirement of shares resulting from mergers are included, the average change in shares is no longer significantly correlated with the equity ...

Has the stock market become too narrow?
The price of equity has soared during the past five years, stoking concerns that stocks' prices might have risen too far, too fast. These concerns became more pressing as the values of equities rose much more rapidly than earnings during 1998 and early 1999, lifting stocks' prices to record highs relative to their earnings. Although many indexes of stocks' prices continued to rise sharply in 1998 and 1999, fewer stocks contributed to this performance. The market became more narrow as the running count of stocks whose prices were rising fell behind that for stocks whose prices were dropping. ; ...

Density selection and combination under model ambiguity: an application to stock returns
This paper proposes a method for predicting the probability density of a variable of interest in the presence of model ambiguity. In the first step, each candidate parametric model is estimated minimizing the Kullback-Leibler 'distance' (KLD) from a reference nonparametric density estimate. Given that the KLD represents a measure of uncertainty about the true structure, in the second step, its information content is used to rank and combine the estimated models. The paper shows that the KLD between the nonparametric and the parametric density estimates is asymptotically normally distributed. ...

Dynamic strategies, asset pricing models, and the out-of-sample performance of the tangency portfolio
In this paper, I study the behavior of an investor with unit risk aversion who maximizes a utility function defined over the mean and the variance of a portfolio's return. Conditioning information is accessible without cost and an unconditionally riskless asset is available in the market. ; The proposed approach makes it possible to compare the performance of a benchmark tangency portfolio (formed from the set of unrestricted estimates of portfolio weights) to the performance of a restricted tangency portfolio which uses single-index and multi-index asset pricing models to constrain the first ...

Treasury inflation-indexed debt: a review of the U.S. experience
This article describes the evolution of Treasury inflation-indexed debt securities (TIIS) since their introduction in 1997. Over most of this period, TIIS yields have been surprisingly high relative to those on comparable nominal Treasury securities, with the spread between the nominal and indexed yields falling well below survey measures of long-run inflation expectations. The authors argue that the low relative valuation of TIIS may have reflected investor difficulty adjusting to a new asset class, supply trends, and the lower liquidity of indexed debt. In addition, investors may have had a ...

Does the macroeconomy predict U.K. asset returns in a nonlinear fashion? comprehensive out-of-sample evidence
We perform a comprehensive examination of the recursive, comparative predictive performance of a number of linear and non-linear models for UK stock and bond returns. We estimate Markov switching, threshold autoregressive (TAR), and smooth transition autoregressive (STR) regime switching models, and a range of linear specifications in addition to univariate models in which conditional heteroskedasticity is captured by GARCH type specifications and in which predicted volatilities appear in the conditional mean. The results demonstrate that U.K. asset returns require non-linear dynamics be ...

An efficiency perspective on the gains from mergers and asset purchases
A simple efficiency-based view states that acquisitions shift assets to more productive owners. This implies that expected returns from acquisitions increase with transaction value. We propose using the sensitivity of abnormal returns to scaled transaction value as a measure of efficiency gains. Using this method, we find that the average acquirer obtains an increase of 3% - 5% in the value of the acquired assets. However, efficiency gains vary sharply across acquirer and deal characteristics. We find statistical significance for interactions of relative value and variables known to affect ...
