**ELROY DIMSON, PAUL MARSH**

This paper describes an empirical study of over 4000 specific share return forecasts made by 35 UK stockbrokers and by the internal analysts of a large UK investment institution. A comparison of forecast and realised returns reveals a small but potentially useful degree of forecasting ability. A large part of the information content of the forecasts, however, appears to be discounted in the market place within the first month. Nevertheless, an analysis of some 3000 transactions motivated by, and executed at the time of, the forecasts shows that the apparent predictive ability of the recommendations could be translated into superior performance by the fund's investment managers. Differences in forecasting ability between brokers do not appear to persist over time, but predictive accuracy can be improved by pooling simultaneous forecasts from different sources.

Stock Returns, Inflation, and Economic Activity: The Survey Evidence

**JOEL HASBROUCK**

The primary purpose of this paper is the use of survey expectations data to study the empirical relationships between stock returns, inflation, and economic activity. In the course of this analysis and as a secondary purpose, the paper discusses general considerations involving the use of expectations proxies and makes recommendations for econometric techniques. The main empirical findings are: (1) Hypothesized relationships between expected economic activity and expected inflation do not in practice appear to be important in explaining the negative relationship between expected inflation and stock returns. (2) Nevertheless, the survey data do lend some support to the hypothesis of a quantity theory relationship between expected inflation and expected economic activity, holding constant monetary growth. (3) The crossâforecaster dispersion of economic activity forecasts, a proxy for real uncertainty, appears to be a significant determinant of stock returns. Inclusion of this variable eliminates the negative impact of expected inflation.

Estimating the Correlation Structure of International Share Prices

Recently, the case for international portfolio diversification has been convincingly argued in the framework of meanâvariance portfolio analysis by a number of researchers. However, virtually no empirical documentation exists concerning the best method for estimating the correlation structure of international share prices. In this paper, 12 models for estimating the international correlation matrix are presented and empirically tested relative to full historical extrapolation. The major evaluation criteria are the mean squared error and stochastic dominance based on the frequency distribution of the squared forecast errors. The results indicate that the National Mean Model strictly dominates all the others in terms of forecasting accuracy.

**FREDERIC S. MISHKIN**

This paper conducts empirical tests of the equality of real interest rates across countries. The empirical evidence strongly rejects the hypothesis of real rate equality and the joint hypotheses of uncovered interest parity and ex ante relative PPP, or the unbiasedness of forward rate forecasts and ex ante relative PPP. The evidence suggests that it is worth studying open economy macroeconomic models which allow: 1) domestic real rates to differ from world rates, 2) time varying risk premiums in the forward market, or 3) deviations from ex ante relative PPP.

Credit Rationing and Financial Disorder

**JACK GUTTENTAG, RICHARD HERRING**

We develop a model of lender behavior in the presence of default risk and moral hazard that determines default premiums and identifies the conditions under which borrowers are rationed. A hypothesis regarding a cognitive bias in the formation of expectations provides a dynamic component to our analysis and allows us to explain how an economy becomes vulnerable to a financial crisis and why vulnerability may increase over time.

Stability of the U.S. Short-Run Money Demand Function, 1959-81

**KUAN-PIN LIN, JOHN S. OH**

Stability tests are performed for the conventional U.S. money demand equation using switch regression techniques. This methodology provides for the identification of the shift point and the type of shift (abrupt or drift), and is conducive to hypothesis testing to determine the sources of the shift for the regression equation. Our findings do not support the contention that the 1974 change in money demand equation is a downward shift in the constant term, as suggested by many recent empirical money demand studies.

New Evidence That Taxes Affect the Valuation of Dividends

**JAMES M. POTERBA, LAWRENCE H. SUMMERS**

This paper uses British data to examine the effects of dividend taxes on investors' relative valuation of dividends and capital gains. British data offer great potential to illuminate the dividends and taxes question, since there have been two radical changes and several minor reforms in British dividend tax policy during the last 30 years. Studying the relationship between dividends and stock price movements during different tax regimes offers an ideal controlled experiment for assessing the effects of taxes on investors' valuation of dividends. Using daily data on a small sample of firms, and monthly data on a much broader sample, we find clear evidence that taxes affect the equilibrium relationship between dividend yields and market returns. These findings suggest that taxes are important determinants of security market equilibrium and deepen the puzzle of why firms pay dividends.

The Structure of Asset Prices and Socially Useless/Useful Information

**JAMES A. OHLSON**

This paper relates the value of additional information to asset prices in a pure exchange setting. The price structure of interest revolves around a âpricingâhypothesisâ: the prices in an economy with less information are unbiased estimators of the prices that would obtain in a more informative economy. Two basic results are developed. First, if the incremental information is useless then the pricingâhypothesis applies. Second, if the pricing hypothesis is assumed valid, then the information is valuable in a weak sense. The results are also considered in the context of empirical research. The case is made for viewing statistical tests of association between prices and signals as tests of the social value of information.

Additional Evidence on the Relation Between Divestiture Announcements and Shareholder Wealth

**JAMES D. ROSENFELD**

This paper presents estimates of the effect of voluntary divestiture announcements on shareholder wealth. The results show that both spinâoff and sellâoff announcements tend to have a positive influence on the stock prices of the divesting firms, and that the spinâoffs âoutperformâ the sellâoffs on the day of the event. We also find that the economic gains to the shareholders of the selling and acquiring firms are nearly identical, suggesting that the sellâoff decision is perceived by both investor groups as a positive net present value (NPV) transaction.

Mean-Gini, Portfolio Theory, and the Pricing of Risky Assets

**HAIM SHALIT, SHLOMO YITZHAKI**

This paper presents the meanâGini (MG) approach to analyze risky prospects and construct optimum portfolios. The proposed method has the simplicity of a meanâvariance model and the main features of stochastic dominance efficiency. Since meanâGini is consistent with investor behavior under uncertainty for a wide class of probability distributions, Gini's mean difference is shown to be more adequate than the variance for evaluating the variability of a prospect. The MG approach is then applied to capital markets and the security valuation theorem is derived as a general relationship between average return and risk. This is further extended to include a degree of risk aversion that can be estimated from capital market data. The analysis is concluded with the concentration ratio to allow for the classification of different securities with respect to their relative riskiness.

**CLARENCE C. Y. KWAN**

In this study a simple common algorithm which is applicable to seven models is proposed for optimal portfolio selection disallowing short sales of risky securities. The models considered in the analysis consist of a single index model, four multiâindex models, and two constant correlation models. Unlike the previous approach, the proposed algorithm does not require explicit ranking of securities. Therefore, it is particularly useful for two multiâindex models with orthogonal indices which do not provide any ranking criterion. Also, because of its algorithmic efficiency as demonstrated in a simulation study on models with multiple groups, the approach here can enhance their usefulness in portfolio analysis.

On Testing the Arbitrage Pricing Theory: Inter-Battery Factor Analysis

**D. CHINHYUNG CHO**

This paper tests the Arbitrage Pricing Theory (APT) by estimating the factor loadings that are consistent between two industry groups of securities. One of the pitfalls in the study by Roll and Ross is that the factors estimated in one group may not be the same with the factors estimated in another group. This raises some concerns on the acceptability of their conclusions. For our study, we employ interâbattery factor analysis which enables us to estimate factor loadings by constraining the factors to be the same between two different groups. Our results show that there seem to be five or six interâgroup common factors that generate daily returns for two industry groups of securities, and these interâgroup common factors do not seem to depend on the size of groups. Also, based on our crossâsectional tests on the risk premia, we conclude that the APT should not be rejected.

**MARK RUBINSTEIN**

Under conditions consistent with the BlackâScholes formula, a simple formula is developed for the expected rate of return of an option over a finite holding period possibly less than the time to expiration of the option. Under these conditions, surprisingly, the expected future value of a European option, even prior to expiration, is shown equal to the current BlackâScholes value of the option, except that the expected future value of the stock at the end of the holding period replaces the current stock price in the BlackâScholes formula and the future value of a riskless invesment of the striking price replaces the striking price. An extension of this result is used to approximate moments of the distribution of returns from an option portfolio.

The American Put Option Valued Analytically

**ROBERT GESKE, H. E. JOHNSON**

An analytic solution to the American put problem is derived herein. The hedge ratio and other derivatives of the solution are presented. The formula derived implies an exact duplicating portfolio for the American put consisting of discount bonds and stock sold short. The formula is extended to consider put options on stocks paying cash dividends. A polynomial expression is developed for evaluating these formulae. Values and hedge ratios for puts on both dividend and nondividend paying stocks are calculated, tabulated, and compared with values derived by numerical integration and binomial approximation. As with European options, evaluating an analytic formula is more efficient than approximating the stock price process or the partial differential equation by binomial or finite difference methods. Finally, applications of this American put solution are discussed.

The Valuation of Options When Asset Returns Are Generated by a Binomial Process

**R. C. STAPLETON, M. G. SUBRAHMANYAM**

This paper values options on assets whose returns, over a finite interval of time, are generated by a binomial process. It shows that a simple valuation relationship, between the option and the underlying stock, obtains if investors have preference functions that belong to a particular class, even if opportunities to hedge do not exist. One particular application of the theory is in the case where the stock price over a finite interval could increase by an amount, fall by the same amount, or stay at the same level. The results in this paper may be viewed as the foundation of the preferenceâbased approaches to obtaining a risk neutral valuation relationship.

A Risk Minimizing Strategy for Portfolio Immunization

**H. GIFFORD FONG, OLDRICH A. VASICEK**

Consider a fixedâincome portfolio whose duration is equal to the length of a given investment horizon. It is shown that there is a lower limit on the change in the endâofâhorizon value of the portfolio resulting from any given change in the structure of interest rates. This lower limit is the product of two terms, of which one is a function of the interest rate change only, and the other depends only on the structure of the portfolio. Consequently, this second term provides a measure of immunization risk. If this measure is minimized, the exposure of the portfolio to any interest rate change is the lowest.

**JIMMY E. HILLIARD**

This study develops and tests a methodology for reducing interest rate risk in a fixed spot portfolio of assets and liabilities with defaultâfree cash flows. A minimum variance hedge is constructed by adding a portfolio of financial futures to the spot portfolio. Theorems are given which establish necessary and sufficient conditions for the existence of unique and zeroâvariance hedges. The risk reduction characteristics of the methodology are demonstrated by an empirical analysis.

**EARL L. GRINOLS**

This paper extends Merton's intertemporal capital asset pricing model with multiple consumers to include a description of the supply of traded securities. The production decisions of firms are described in a model with stochastic investment opportunities and incomplete markets. Firms maximize the welfare of their stockholders based on the sum of dollar values placed on the projects by shareholders of the firm. The monetary value to stockholders of a marginal change in the contract structure due to changing firm production is analyzed. In this setting, the competitive market achieves an appropriately defined NashâConstrained Pareto Optimum. Sufficient conditions for investor unanimity, marketâvalue maximization by firms, and the equilibrium to achieve a Constrained Pareto Optimum and full Pareto Optimum are derived.

This paper decomposes daily close to close returns into trading day and nonâtrading day returns. We discover that all of the average negative returns from Friday close to Monday close documented in the literature for stock market indexes occurs during the nonâtrading period from Friday close to Monday open. In addition, average trading day returns (open to close) are identical for all days of the week. January/firm size/turnâofâtheâyear anomalies are shown to be interrelated with dayâofâtheâweek returns.
