Determinants of the abandonment of previously announced capacity expansions are analyzed in eleven industries within the North American pulp and paper sector. Given the investor's initial confidence, extent of precommitment of resources, and post-announcement fresh news, abandonment's likelihood increases with unanticipated projects subsequently announced by rivals. The process suggests a continual auction with the winning projects and firms having certain systematic properties. Unexpected announcements by rivals promote abandonment only in less concentrated industries; elsewhere completion is actually encouraged. Short-run price competition is found highly sensitive to capacity utilization, and the market's geographic scope is tested. [ABSTRACT FROM AUTHOR]

We test whether environmental regulation affects investment decisions, using Census data for individual paper mills. New mills in states with strict environmental regulations choose cleaner production technologies, with differences in air and water pollution regulation also influencing technology choice. Examining investment allocation across existing plants, we find that abatement and productive investment tend to be scheduled together. However, plants with high abatement investment over the entire period spend significantly less on productive capital. This seems lo reflect both environmental investment 'crowding out' productive investment within a plant, and firms shifting investment towards plants facing less stringent abatement requirements.

I test the disposition effect, the tendency of investors to hold losing investments too long and sell winning investments too soon, by analyzing trading records for 10,000 accounts at a large discount brokerage house. These investors demonstrate a strong preference for realizing winners rather than losers. Their behavior does not appear to be motivated by a desire to rebalance portfolios, or to avoid the higher trading costs of low priced stocks. Nor is it justified by subsequent portfolio performance. For taxable investments, it is suboptimal and leads to lower after-tax returns. Tax-motivated selling is most evident in December. [ABSTRACT FROM AUTHOR]

The article presents commentary from Jessica A. Wachter about a paper written by Yacine Ait-Sahalia and Michael W. Brandt entitled (A&B) "Variable Selection for Portfolio Choice," which appeared in the August, 2001 issue of the "Journal of Finance." In that paper A&B employed conditional moments of return to select an optimal portfolio. The author of the current paper acknowledges the validity of their work for single-period investments, but raises questions about its suitability for investments that extend over multiple periods.

The three papers presented at this session have provided a fine balance of theoretical analysis and statistical investigation. The paper by Black and Scholes is a particularly commendable contribution, thoroughly professional in execution and a very constructive piece of work in its broader implications. The authors has previously derived an equation for the valuation of options from the condition that opportunities for profitable arbitrage will be eliminated in efficient capital markets. In the present paper they carefully analyze a sizeable body of data to examine the efficiency of the operation of the option market as it is now structured. They validate their formula for the pricing of options by showing that in the absence of transactions costs, buying "undervalued" contracts and selling "overvalued" contracts at model prices computed with foreknowledge of the actual variances of the returns on the underlying stock over the holding period would produce quite insignificant average gains or losses. But when ex ante variances are estimated from previous stock price histories, buying "undervalued" contracts and selling "over-valued" contracts at model prices would have produced significantly negative excess portfolio returns, while substantial positive excess portfolio returns would have been made by buying overvalued and selling undervalued options at market prices. These results indicated that the true value of options is somewhere midway between market prices and "model" prices based on historical data. [ABSTRACT FROM AUTHOR]

The article presents commentary about a paper written by E. Han Kim entitled "Miller's Equilibrium, Shareholder Leverage Clienteles, and Optimal Capital Structure," which was published in the May, 1982 edition of the "Journal of Finance." The author regards Kim's paper as a survey of research on optimal capital structure inspired by Merton Miller's article "Debt and Taxes." He discusses the portion of Kim's paper that contrasted complete and incomplete capital market environments, and notes the importance of tax arbitrage restrictions in understanding them.

This paper analyzes the major factors which determine the effects of taxation on the value of risky assets and on the cost of capital, and shows how the magnitudes and even the signs of these effects depend on the values assumed for a few key parameters in the model. Using plausible values for these parameters, it is shown that the results obtained are frequently counter-intuitive. [ABSTRACT FROM AUTHOR]

Several recent writings have raised questions concerning the effectiveness of commonly used analytical measures and techniques which have their basis in Modern Portfolio Theory. Questions have been raised about the use of beta in the interpretation of risk adjusted equity performance and about the usefulness of the capital asset pricing model (CAPM) as a tool for measuring and interpreting investment performance. This paper restricts itself to questions concerning beta and CAPM as they relate to performance measurement. In the process of this examination it discusses some basic principles of performance measurement as they relate to judgments of investment management skill and ability. It has been shown that simple applications of beta used in adjusting equity performance for risk can possibly produce misleading or incorrect interpretations of risk adjusted performance. Errors have been shown to be related to the market index used as a basis for the determination of beta. These findings are independent of the validity of CAPM, but the line of reasoning which leads to these conclusions is not totally antithetical to the derivation of CAPM. This paper has three major sections: 1. The capital asset pricing model is assumed to be valid, and a broader index of capital assets is constructed. This index is “better” in the sense that it includes many more assets than the S&P 500 and hence is more complete. 2. The better index is then used to “game” performance measurement using current investment technology and the Standard & Poor's 500. 3. Some conclusions are drawn as to the effectiveness of gaming and the ways in which performance measurement numbers should be interpreted in general. General issues are discussed in the text. A parallel, more detailed and more technical argument is presented in the appendix. [ABSTRACT FROM AUTHOR]

This article explores whether variable life insurance and mutual funds are competitive products. In considering whether variable life insurance and mutual funds are comparable products, the author emphasizes that both utilize a pool of securities as a funding vehicle. In the case of the mutual fund, the purchaser has direct ownership of a pro-rata share of the pool of securities and the benefits desired are solely to accumulate value. Investment performance of a mutual fund, assuming dividends are reinvested, is used to provide more of the same, that is, an increase in the accumulated value.

The article presents commentary from M.J. Brennan about a paper written by Nicholas Barberis and Ming Huang (B&H) entitled "Mental Accounting, Loss Aversion, and Individual Stock Returns," which appeared in the August, 2001 issue of the "Journal of Finance." In that paper B&H analyzed the behavior of investors who are concerned about the returns of both their portfolios and the individual stocks that compose them. The author of the current paper observes that this represents a departure from modern portfolio theory. In his view B&H's analysis, while interesting and informative, must be approached with caution.

This paper investigates options market reaction to changes in the instantaneous variance of the underlying asset. There are three main findings. First, options market investors underreact to individual daily changes in instantaneous variance. Second, these same investors overreact to periods of mostly increasing or mostly decreasing daily changes in instantaneous variance. Third, they tend to underreact (overreact) to current daily changes in instantaneous variance that are preceded mostly by daily changes of the opposite (same) sign. The third finding can reconcile the first two and is also consistent with well-established cognitive biases. [ABSTRACT FROM AUTHOR]

A Treasury Inflation-Protected Security (TIPS) is virtually risk free. As an obligation of the U.S. Treasury, it is mostly free of default risk. As an inflation-indexed security held to maturity, it is risk free in terms of purchasing power. However, investing in a TIPS-only portfolio for retirement is not risk free. This paper presents the results of a simulation analysis designed to evaluate the performance of a portfolio of inflation-indexed Treasury coupon bonds. This study demonstrates that significant shortfall risk exists for TIPS-only portfolios across a range of savings plans and the securities selection rules. [ABSTRACT FROM AUTHOR]

The preceding critique [1] of the paper "The Information Problems in Organizations: A Research Model for the Value of Information and Information Systems" [3], reaches general conclusions with respect to the original paper and the applicability of economics to MIS research. These conclusions are based on arguments developed at a different level of analysis than that used in the original paper, and without considering the goals and intent of the original paper. The differences between the critique and the original paper are highlighted. [ABSTRACT FROM AUTHOR]

This paper answers the comments of readers of our earlier paper. Additional insight is gained by adding recent data to show the effect of following Value Line Investment Service recommendations in active stock market trading over the years 1974-81. We show that Value Line makes a statistically significant contribution, which cannot be explained by the Beta risk factor. We offer our results as an unexplained divergence from the Efficient Market Hypothesis, but with the tentative hypothesis that investment timing (i.e., the fact that the Efficient Market Hypothesis does not operate instantaneously) may explain much of the abnormality.

In this paper we will introduce and develop a nontraditional theory of portfolio selection. The theory assumes that investors choose their portfolios to have a certain minimax property which we will describe in detail below. As we will see in the next two sections, the minimax portfolios turn out to be identical to portfolios that are often recommended on other grounds. In this paper we have examined the implications of certain forms of minimax behavior in portfolio selection. Though minimax behavior is not truly optimal, there are reasons to suppose that it might approximate the behavior of some investors. One reason is the obvious discomfort that many decision-makers feel when forced to make decisions based on subjective probability distributions, particularly when those distributions were formed on the basis of vague information. One would not be surprised if a decision-maker sought to protect himself against the possibility that his distribution is incorrect. Portfolio selection seems a natural context for minimax behavior because of the enormous amount of information, both direct and indirect, that an investor must incorporate into his probability distributions. The results of this paper, which show that minimax behavior leads to reasonable portfolios of the sort we observe in practice, lend some support to the minimax hypothesis. [ABSTRACT FROM AUTHOR]

Taxes affect capital budgeting under inflation in many ways. This note focuses on two of the most important—depreciation deductions and interest deductions. Because depreciation for tax purposes is based on historical costs rather than current values, investments in depreciable assets become less attractive under inflation. Because debtors can deduct nominal interest payments, not just real interest charges, debt-financed investments become more attractive under inflation. The impact of inflation and taxes on the value of potential investment projects depends on which factor dominates. In a recent paper in this journal, Gandolfi argued that the existence of a tax on corporate profits will not alter the real rate of return on the firm's marginal investment. In a subsequent paper, Jaffe exposed Gandolfi's error in ignoring the tax subsidy to debt-financed investments. Both authors assumed that the firm's investment takes the form of a non-depreciating machine—a special case, as Jaffe notes, among an infinite number of possible depreciation schedules. An extension of Jaffe's analysis to handle alternative depreciable lives confirms his assertion that investments which would be marginal in a world without taxes can become profitable in a world with taxes. However, the cutoff rate of return exceeds the rate calculated by Jaffe whenever the machines have finite lives. Moreover, in the limiting case of an asset which has a single period life, the required rate of return will be unaffected by a tax on profits. The section which follows introduces a depreciable asset into Jaffe's analysis; quantitative results of the impact of inflation and taxes on the firm's cutoff rate of return are calculated. Section three summarizes the main conclusions from the analysis. [ABSTRACT FROM AUTHOR]

In the early sixties a number of papers developed stock value models in which the cost of equity capital is a function of the firm's equity investment rate. The conclusions reached, however, have for the most part been rejected in the subsequent literature. Instead, it has become widely accepted both in the theoretical work and in the textbooks on finance that the cost of equity capital is equal to the yield at which a firm's stock is selling, and the latter is independent of the firm's investment rate. In fact, one frequently finds the two terms, share yield and cost of equity capital used interchangeably in the literature. However, contributions to the literature during the last few years provide additional support for and clarification of the alternative theory, and a broad reconsideration of the subject is in order. Part I below critically reviews the literature of the early sixties on both sides of the subject and certain subsequent papers which contributed to the conclusion that share yield and cost of equity capital are equal and independent of investment policy. Parts II and III examine the recent contributions which have materially strengthened the theoretical basis for the contrary conclusion, that the cost of equity in a firm is an increasing function of its investment rate. Part IV reviews the empirical evidence on the subject, and Part V both summarizes the conclusions reached and discusses the areas in which the model requires further development.

This paper analyzes how mutual fund performance relates to past performance. These tests are based on a multiple portfolio benchmark that was formed on the basis of securities characteristics. We find evidence that differences in performance between funds persist over time and that this persistence is consistent with the ability of fund managers to earn abnormal returns.

The assumption that the market portfolio follows a specified diffusion process implies, in a simple equilibrium framework, that the representative individual must have a certain utility function which is identified in the paper. Not every diffusion process is viable, i.e., can be "endogenized" to be the market portfolio's price process in such an equilibrium model. The paper provides necessary and sufficient conditions for viability which imply that viable diffusion processes constitute a rather restricted family. [ABSTRACT FROM AUTHOR]

This paper has introduced L(W[sub 0], k, A) and R(W[sub 0], k, A) as three-parameter risk measures embodying decisions about a reference level about which deviations are to be measured, the relative importance of small versus large deviations, and the range of deviations that will be included in the risk measure. The popular risk measures of variance, semi-variance, mean absolute deviation, and probability of an outcome worse than some prespecified level are special cases of L(W[sub 0], k, A) and standard deviation is a special case of R(W[sub 0], k, A). These risk measures were shown to differ in their choice of one or more of the parameters W[sub 0], k, and A. It was shown that both L and R are monotone increasing functions of A; however, neither L nor R are necessarily monotone increasing functions of k. Clearly L(W[sub 0], k, A) and R(W[sub 0], k, A), are not the only potentially useful functions of the three decision parameters that have been implicit in the selection of the popular risk measures; they are, however, a rich and fairly general family. Further study of their properties should lead to advances in the theory of risk and specification of criteria for the selection of risk measures. This paper has attempted to establish a foundation for these advances. [ABSTRACT FROM AUTHOR]

A conference paper is presented that examines firm income taxation and asset expansion. The author explores some of the problems associated with the measurement of asset expansion during periods of changing price levels. The author investigates the impact that changes in corporate income tax rates have on asset expansion and offers some suggestions on how to stimulate investments by means of special tax measures.

If papers presented at our annual meetings are not addressed to the small group of academicians who attend the actual programs, but to a much larger audience that includes decision makers in the field, then Dr. Pellatt's paper on the analysis of real estate investment opportunities represents a significant contribution. He has done a competent, intelligent job of applying capital budgeting theory to the problem of real estate investment. Admittedly, there is nothing new or unique in the tools, techniques, or concepts employed in his paper, but he has produced a worthwhile marriage. He brings together a potentially fruitful union of capital budgeting, where we have had significant progress in the last decade, with the field of real estate evaluation where we have had little change in the last century.

What caused the recovery from the British Great Depression? A leading explanation – the 'expectations channel' – suggests that a shift in expected inflation lowered real interest rates and stimulated consumption and investment. However, few studies have measured, or tested the economic consequences of, inflation expectations. In this paper, we collect high‐frequency information from primary and secondary sources to measure expected inflation in the United Kingdom between the wars. A high‐frequency vector autoregression suggests that inflation expectations were an important source of the early stages of economic recovery in interwar Britain. [ABSTRACT FROM AUTHOR]

This study presents a novel framework for investment prioritisation in a distribution network by performing a flexibility needs assessment with regards to power quality parameters. Power range and time instances of activation are identified with a view of maintaining normal operation. A step forward is made by incorporating the importance of the flexibility needs assessment in investment prioritisation as part of the network expansion planning. The proposed framework consists of three procedures: input data preparation, operational calculations and the post-processing of results, which are used to quantify the flexibility needs and propose an investment prioritisation list. A bus node, which forms a part of the existing distribution network in Slovenia, is used to demonstrate the general applicability of the framework. As a result, an investment prioritisation list was compiled by assessing the flexibility needs. The secure power supply buffer of the node is determined, while the quantification of the flexibility power range and time instances of activation are also provided in order to further mitigate network constraints. Apart from providing valuable information to network operators, the newly proposed framework lays the foundation for aggregators and market players to plan and self-balance their portfolio and position when providing flexibility market services.

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors' satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors' satisfaction and lending intention. Some specific features of China's online lending market are identified, which provides valuable insights for online lending platforms and the government. [ABSTRACT FROM AUTHOR]

This paper studies the allocational effects associated with the precision of accounting estimates when the precision of estimates is a choice variable for firms. One part of the paper considers the effects of the observability of precision choices. We show that, generally, making precision choices private increases firms' equilibrium precision choices and also, as a by-product, their equilibrium investment choices. We further show that, when firms' precision choices are private, there may be a “disclosure trap,” in which, unless investors conjecture the owner has chosen an estimate with the highest possible precision, the owner will respond to investors' conjecture by choosing an estimate whose precision is higher than investors' conjecture. In a multifirm version of the model with endogenous investment, we show that the equilibrium investment by the firm increases in the precision of the firm's own estimate and decreases in the precisions of other firms' estimates. Finally, we show that, in a setting where the firm's initial owner sells his stake in the firm over the course of two periods, with disclosures of estimates of the firm's value occurring prior to each sale of shares, if the precisions of the estimates are public, the equilibrium precisions of the estimates increase over time when the owner sells a sufficiently large fraction of the firm in the first period, and otherwise the equilibrium precisions of estimates remain constant over time.

The article comments on the paper "Real Investment Implications of Employee Stock Option Exercises," by Daniel A. Bens, Venky Nagar and M.H. Franco Wong, presented at the 2001 Journal of Accounting Research Conference. The paper examined the link between employee stock option exercises, treasury stock purchases and real investments for Standard & Poor's 500 firms between 1998 and 1999. The authors of the paper make the assumption that firms route cash from profitable investment expenditures to fund share repurchases, attempting to alleviate earnings-per-share dilution from stock option exercises. The author notes that participants of the conference questioned the validity of the four assumptions made by the paper, particularly concerning the concept of stock option dilution in firms which use options for incentive purposes.

In co‐expansion planning of generation and storage systems, the investor aims to determine the time, location, and capacity of the generation energy storage units. The main challenge is to install these systems in a way that the investor's profit is maximized. In addition, market‐clearing must take place in order to optimize social welfare. This paper studies a co‐expansion planning problem as a bi‐level model that involves the expansion of generation and energy storage units. Generating units include wind and gas turbines and the energy storage system (ESS) is compressed air. This paper addresses the upper‐level problem of increasing investor profits and the lower‐level problem of increasing social welfare. Simulation results show that an investor can achieve the highest possible profit by simultaneously investing in the wind and gas turbine as well as the storage systems using strategic behaviour (price offer/bid close to market price) and participating in the spot market and guaranteed purchase contract. In addition, improving the load growth rate and guaranteed purchase contracts increase the investment in the generation‐storage units. The simulation results of this study are compared with other studies for validation purposes. [ABSTRACT FROM AUTHOR]

The article presents discussion regarding the 19867 paper "Optimal Portfolio Choice Under Incomplete Information," by G. Gennotte. The article discusses research done on investment decisions in a Merton/Cox Ingersoll & Ross production economy. The article states that Gennotte's paper provides two interesting observations: that an increase in the uncertainty regarding instantaneous expected returns of a certain production process will reduce its weight in the portfolio, and that the decisions of investors with logarithmic preferences behave as if the conditional means are the true ones, given that their estimates of expected returns are independent of the estimation error.

This section introduces a series of articles on real estate investment trusts and securities pricing.

Value capture means capturing in some way the value of an investment in public infrastructure. Value capture methods include five forms of property‐related taxes: a tax on land value uplift, a broad‐based land tax, selective land tax, property taxes and transaction taxes. They may also include three forms of user charges: developer charges, consumer charges and sale of development rights. The paper assesses these options against three standard policy objectives of efficiency, equity and practicality. The paper finds that all three main forms of user charges meet these criteria. Special area land and property taxes may be appropriate in limited cases. Pure betterment taxes on land value uplift are rarely practical. [ABSTRACT FROM AUTHOR]

This paper investigates the effect of inflation on a firm's investments in fixed assets. When future prices are certain, inflation affects the present value of depreciation tax shields, and the impact of inflation on the choice between different lived assets is non-monotonic. Future asset price uncertainty creates a valuable switching option and benefits shorter-lived assets. [ABSTRACT FROM AUTHOR]

This paper provides some new insights about approximate factor structures, as defined by Chamberlain and Rothschild [2], and their implications for empirical tests. First, we show that any economy that satisfies an approximate factor structure can be transformed, in a manner that does not alter the characteristics of investor portfolios, into an economy that satisfies an exact factor structure, as defined by Ross [9]. Second, we show that principal components analysis represents just one of many methods of forming groups of well-diversified portfolios with no idiosyncratic risk in large samples. Correct factor loadings will be obtained by regressing security returns on any group of these portfolios. Our interpretations of the Chamberlain and Rothschild results also provide additional insights into the testability of the Arbitrage Pricing Theory. We show that securities cannot be repackaged to hide factors in the manner suggested by Shanken [10] without the variance of some of the repackaged securities approaching infinity in large economies.

In this paper a systematic procedure is developed to determine necessary conditions for all degrees of stochastic dominance. The previously known necessary conditions are specified as to which degrees of dominance they belong, and two new necessary conditions, a ranking of harmonic means and a ranking of algebraic combinations of the first three moments, are derived.

This paper demonstrates that the response of nominal interest rates to changes in inflationary expectations should lie between that predicted by the "Fisher" and "Darby" effects. The exact nature of the response will depend on the relative size of the income and capital gains tax rates, and the relative size of the derivatives of investment and savings to their respective after-tax real rates. The other major conclusion of this paper is that capital gains taxation offsets the negative effect on investment produced by treating depreciation on a historic rather than a replacement cost basis.

The structure of security returns has been an object of constant attention in the financial economics literature. Several stochastic models for security returns have been proposed, and many of these subjected to strenuous empirical testing. Yet theory demands closure: security returns do not exist in isolation, but are intimately interconnected to all the other features of an economy in equilibrium. Of concern are the consistency of contemporaneous features, such as interest rates and prices, and importantly the dynamic characteristics, i.e., whether equilibrium is sustained over a multiperiod environment. In this paper, we develop a consistent, dynamic equilibrium for the Ross arbitrage model of capital asset pricing. Our objective is to develop a multi-period model which is consistent with the Ross K-factor linear return generating process and its associated single-period equilibrium. Section 2 of the paper gives the initial description of the Ross model. In section 3 we construct a dynamic equilibrium. The state space is given by current dividends and these in turn are mapped into current prices. Section 4 demonstrates that additional state variables of an "informational" nature can also be introduced without damaging the essential structure of equilibrium. Several of the points developed herein are also discussed in Garman and Ohlson where the focus centers on valuation in arbitrage-free markets generally; here we concentrate purely on the dynamic equilibrium nature of the Ross model in particular.

In the period following Modigliani and Miller's correction paper, it was generally agreed that where capital markets are perfect (taxes notwithstanding) there is an advantage to debt financing. In reaching this conclusion, Modigliani and Miller disregarded the effect of personal income taxes on the behavior of investors. When Miller introduced personal income taxes into the analysis, he was able to state that for a wide range of values of dividend, interest, and corporate tax rates "the gain from leverage vanishes entirely or even turns negative" (p. 267). In deriving this result Miller assumed the following: (1) all investors are taxed at the same rate; (2) the objective of the firm is to maximize its value; (3) no capital gains tax exists; (4) no bankruptcy risk exists; and (5) the firm pays all of its earnings in dividends. Later on in his paper Miller drops assumption (1) in order to reach the surprising result that there is no optimal capital structure for the individual firm but there is an economywide optimal capital structure. This paper argues that when individuals differ in the tax rates imposed on their interest income, value maximization is a meaningless dictum. Assumption (1) is therefore adopted throughout in order to investigate the impact of removing assumptions (3), (4), and (5). A short discussion of previous references to these assumptions is in order. [ABSTRACT FROM AUTHOR]

A great deal of recent research has been concerned with the effect of inflation on economic variables such as the interest rate, the premium for risk, and the value of the firm. Many of these articles have argued that, except for depreciation effects, the value of future investments in a world with taxes is unaffected by a change in the rate of inflation. Since it is difficult to discuss in depth the work of many writers, we will zone in on the reasoning of this type employed in only one paper, the recent article by Gandolfi. However, we believe that the discussion presented here has implications formerly other articles as well. As is common in the literature, Gandolfi builds his macromodel in two steps. First, he sets up the investment, consumption and other schedules as functions of simple parameters such as income and the rate of interest. Second, he combines the schedules to determine the equilibrium values of these parameters. This note is only concerned with part of the first step since we merely want to reevaluate the investment schedule. Since we believe that the use by Gandolfi and others of the IS/LM and/or the neo-classical growth model for the second step is correct, we leave it to future research to place our amended investment schedule in the appropriate model.

The article comments on a paper published within the issue, "New Evidence on the Capital Asset Pricing Model," by Irwin Friend, Randolph Westerfield, and Michael Granito. The author reviews the paper and discusses the two tests used on the Capital Asset Pricing Model (CAPM). The model is first tested on its own ground, then using an expanded set of securities including bonds and stocks. The author notes that greater availability of bond data makes it possible to better estimate the market portfolio. It is also mentioned that individual bond returns may be used for cross-sectional testing of the CAPM.

Previous work by the authors has described how optimal portfolios can be assembled given various assumptions about the variance covariance arrangement of stock returns, and stipulating the existence of a risk-free asset. The current paper offers additional simplification by relaxing the requirement for a risk-free asset. The authors show how to construct a complete frontier of efficient portfolios for the single-index model, and for when identical correlation coefficients prevail among all stocks.

A balanced commentary on David Glenn's paper, "Super Premium Security Prices and Optimal Corporate Financing Decisions," should be one which indicates what I consider to be two general, but important, contributions of this work, as well as one major negative aspect. On the positive side, Glenn has approached his topic in a very professional, analytical manner. He starts by noting that the real world has investment grade restrictions on some institutional investors, and that this would lead to capital markets which are, to an extent, segmented and possibly could result in premiums on certain quality securities. Premiums could occur due to this institutional requirement, but Glenn, unlike so many before him, does not then jump to the conclusion that these premiums do, in fact, exist. He analyzes, within the two-parameter framework, this partially-segmented capital market structure (assuming perfect capital markets in all other respects) and proceeds to prove that this structure alone is not sufficient to yield price premiums on quality securities. Noninstitutionally constrained investors can simply buy more, or sell short, those securities that are not on their risk-expected return line to wipe out would-have-been premiums. Having carefully demonstrated the emptiness of the institutional quality grade requirement, he then combines this market imperfection with a restriction on short-selling (since the proceeds of a short sale cannot be used) to show that all price deviations from a unified capital market prescription cannot be eliminated by unrestricted investors--thus, the premiums.

The purpose of this paper is to investigate the opposite case: What is the impact of ever lengthening revision horizon on the optimal portfolio of a mean-variance investor? We do not intend to examine in this paper what will be the overall division of the investors' wealth between the riskless asset and the risky portfolio but rather we will determine how in the framework of the mean-variance analysis the long-run investor will construct his risky portfolio. Neither do we intend to examine the adequacy of the mean-variance criterion for this investment in light of the considerable skewness of multiperiod multiplicative returns.

One of the most important problems confronting stock market analysts is the valuation of stocks at any point in time. In fact, the name of the game is to determine whether stocks are selling above or below their real worth. Presumably, "real worth" is synonymous with economic equilibrium based upon the "correct" model of common stock valuation. Deviations from equilibrium will eventually be corrected by the market mechanism and this is the stuff of which profits and losses are made. The purpose of this paper is to extend the work of Malkiel and Cragg since they have apparently opened up a rich vein of exploration in the quest to explain the structure of share prices. The most serious limitation of the Malkiel and Cragg study was its sample size. Unfortunately, the sample was restricted to only 178 corporations. The authors state "... our sample tends to contain the 'blue-chip' group of companies in which investment interest is centered.". Would it be possible to improve the market representativeness and size of the sample and still obtain the excellent results reported by Malkiel and Cragg? In addition to attempting to answer this question, this paper will also consider the role of industrial classification in determining price-earnings ratios holding important financial variables constant. Section II briefly reviews the stock evaluation model. Section III discusses the data source for this study. Section IV reports the regression results while Section V summarizes the findings.

This paper documents that strategies which buy stocks that have performed well in the past and sell stocks that have performed poorly in the past generate significant positive returns over 3- to 12-month holding periods. We find that the profitability of these strategies are not due to their systematic risk or to delayed stock price reactions to common factors. However, part of the abnormal returns generated in the first year after portfolio formation dissipates in the following two years. A similar pattern of returns around the earnings announcements of past winners and losers is also documented. [ABSTRACT FROM AUTHOR]

These objectives are not attainable by any single paper and M & H's attempt is no exception. By other more conventional standards, however, M & H have written an interesting paper.

Professor Ball's paper reports the results of an extremely detailed and exhaustive study of the effect on security prices of changes in accounting techniques affecting the reported net income figure. His contribution is both substantive, in that it provides further evidence in support of the efficient markets hypothesis, and methodological, in that it proposes refinements to the usual technique used to study the impact of new information on stock prices. I shall discuss these two aspects of his paper separately. The major finding of the paper is that capital markets are efficient to the extent that investors are able to see through the accountant's veil to derive independent estimates of the true economic income of firms. We may conclude from this that annual income reports do nothing to obstruct the flow of information from firm to investor, even if they do relatively little to facilitate it. However, it would be wrong to take this as implying that the principle of consistency in accounting is irrelevant' market efficiency is quite compatible with variations in investor sophistication, and it is possible that changes in accounting techniques lead to wealth transfers from the naive to the sophisticated, which would be widely regarded as undesirable.

The purpose of this paper is to derive the three MM Propositions using the standard deviation-mean portfolio model in a market equilibrium context. This approach to some of the major issues of corporation finance enables us to derive these propositions in a somewhat more direct way than with the use of the risk-class assumption and the arbitrage proof of the MM paper. Instead, a model is substituted relating the maximization of stockholder expected utility to the selection of portfolios of assets to, finally, the financing and investment decisions within the corporation, A link will be provided between two branches of the field of finance that have so far been evolving more or less separately.

The article presents comments on the papers "The Changing Role of Banks in the Market for Equities," by A. James Meigs, and "Life Insurance Companies and the Equity Capital Markets," by Orson H. Hart, both published within the issue. The author discusses four separate points presented within the papers: the expected growth in the volume of institutionally managed funds, intensification of competition between institutions, innovations in the form of new services offered to firms or individuals, and the investment preferences of equities.

The article reports on alternative accounting rules and their effect on nonsubsidiary investments and discusses the paper, "The Effect of Alternative Accounting Rules for Nonsubsidiary Investments," by Nicholas Dopuch and David F. Drake. The choice among alternative measurement rules or income and wealth definitions is a continuing problem in accounting. One area of choice is the marketable securities of nonsubsidiary companies where cost basis valuation is typically employed. Dopuch and Drake measured the performance of each alternative accounting rule under appropriate criteria through a sample of 12 firms for the period of 1955-64.
