The profitability of feeding dried poultry droppings-based diet as a supplement in goat production enterprise was analyzed in this present study. The data generated in the study was analyzed using gross margin analysis and profitability ratio. The result of the budgetary analysis showed that the highest total cost of Rs 855.9/goat was incurred, the highest total revenue of Rs 1254.3/goat, highest gross margin of Rs 773.24/goat and highest net farm income of Rs 713.24/goat were observed for the supplemented treatment groups (T2-T5). The profitability ratio gave the best bene- fit-cost ratio of 4.62, a rate of return of 3.62, a gross ratio of 0.22 and an expense structure ratio of 0.12. This suggests that feeding of dried poultry droppings-based diet to goats is a profitable enterprise. This present study, therefore, recommends the supplementation of sun-dried poultry dropping based diet at 80% inclusion level for maximum profitability of goat production enterprises.

Background: This research study is an economic analysis of a neurotechnology-based translational research and development venture focused on the development of a therapy for patients with epilepsy. In the conceptualization, planning, financing, and execution of neurotechnology ventures, many factors come into play in determining value and ability to secure financing at each stage of the venture. Conventionally, these have included factors that determine the return on investment for the stakeholders of the venture, most notably the investors and the team members, the former investing hard earned capital, and the latter investing significant portions of their professional careers. For a variety of reasons, the positive impact on society is often not quantified and taken into consideration. Methods: To address this, a new term is defined and assessed at a first approximation level using an index technology. The metric is termed the societal return on investment (sROI). Results: Among chronic conditions, neurological disease is virtually unique in the magnitude of economic devastation that it can inflict on a person and a family. Because the device costs do not reflect this value that is lost and subject to restoration, these are missing from this important calculation. The index project is the development of a seizure advisory system, which cost $71.2 million to develop and conduct a First-In-Man (FIM) study (NCT01043406) and which was estimated to require $50 million to complete a pivotal study. Conclusion: Despite the immense costs required to develop, test, and commercialize such a system, the direct and indirect economic costs imposed by uncontrolled seizures are sufficiently staggering that a sROI becomes positive after only 400 patients have been successfully treated and returned to work.

Rural Africa lags behind global progress to provide safe drinking water to everyone. Decades of effort and billions of dollars of investment have yielded modest gains, with high but avoidable health and economic costs borne by over 300m people lacking basic water access. We explore why rural water is different for communities, schools, and healthcare facilities across characteristics of scale, institutions, demand, and finance. The findings conclude with policy recommendations to (i) network rural services at scale, (ii) unlock rural payments by creating value, and (iii) design and test performance-based funding models at national and regional scales, with an ambition to eliminate the need for future, sustainable development goals.

Noncommunicable diseases (NCDs) are a broad challenge for decision-makers. NCDs account for seven out of every 10 deaths globally, with 42 percent occurring prematurely in individuals under age 70. Despite their heavy toll, NCDs are underfunded, with only around two percent of global funding dedicated to the disease set. Country governments are responsible for funding targeted actions to reduce the NCD burden, but among other priorities, many have yet to invest in the health-system interventions and policy measures that can reduce the burden. This article examines “investment cases” as a potential mechanism for catalyzing attention to—and funding for—NCDs. In Jamaica, using the UN inter-agency OneHealth Tool, we conducted an economic analysis to estimate the return-on-investment from scaling up strategic clinical interventions, and from implementing or intensifying policy measures that target NCD risk factors. In addition, we conducted an institutional and context (ICA) analysis, interviewing stakeholders across sectors to take stock of promising policy pathways (e.g., areas of general consensus, political appetite and opportunity) as well as challenges to implementation. The economic analysis found that scaling up clinical interventions that target CVD, diabetes, and mental health disorders, and policy measures that target tobacco and alcohol use, would save over 6,600 lives between 2017–2032, and avert JMD 81.3 billion (USD 640 million) in direct and indirect economic costs that result from mortality and morbidity linked to NCDs. The ICA uncovered government economic growth targets and social priorities that would be aided by increased attention to NCDs, and it linked these targets and priorities to the economic analysis.

This article examines the impact of leveraged buyout firms' bank relationships on the terms of their syndicated loans. We examine a sample of 1,590 loans financing private equity sponsored leveraged buyouts between 1993 and 2005, and find that private equity firms' bank relationships are an important factor in cross-sectional variation in the loan interest rate and covenant structure. Our results indicate that bank relationships formed through repeated interactions reduce inefficiencies from information asymmetry and allow leveraged buyouts sponsored by private equity firms to occur on favorable loan terms. A one-standard-deviation increase in bank relationship strength is associated with an 8-basis-point (3%) decrease in the spread and a 0.21-basis-point (4%) increase in the maximum debt to EBITDA covenant. We also find evidence that banks price loans to cross-sell other fee business. A one-standard-deviation increase in both bank relationship strength and cross-selling potential translates into as much as a 4-percentage-point increase in equity return to the leveraged buyout firm.

We examine how managerial incentives affect acquisition decisions in the banking industry. We find that higher pay-for-performance sensitivity (PPS) leads to value-enhancing acquisitions. Banks whose CEOs have higher PPS have significantly better abnormal stock returns around the time of the acquisition announcements. On average, acquirers in the high-PPS group outperform their counterparts in the low-PPS group by 1.4% in a three-day window around the announcement. Higher PPS helps reduce the incentives for making value-destroying acquisitions, while at the same time promotes value-enhancing acquisitions. The positive market reaction can be rationalized by post-merger performance. Following acquisitions, banks with higher PPS experience greater improvements in their operating performance. We show that the effect of PPS is mainly evident in small and medium-sized banks, but is not present in large banks. [ABSTRACT FROM PUBLISHER]

We find a positive cross-sectional relationship between expected stock returns and default risk, contrary to the negative relationship estimated by prior studies. Whereas prior studies use noisy ex post realized returns to estimate expected returns, we use ex ante estimates based on the implied cost of capital. The results suggest that investors expected higher returns for bearing default risk, but they were negatively surprised by lower-than-expected returns on high default risk stocks in the 1980s. We also extend the sample compared with prior studies and find that the evidence based on realized returns is considerably weaker in the 1952–1980 period. [ABSTRACT FROM PUBLISHER]

This article explores the link between the composition of firms’ capital and stock returns. I develop a general equilibrium production economy where firms use two factors: real estate and other capital. Investment is subject to asymmetric adjustment costs. Because real estate depreciates slowly, firms with high real estate holdings are more vulnerable to bad productivity shocks and hence are riskier and have higher expected returns. This prediction is supported empirically. I find that the returns of firms with a high share of real estate capital exceed that of low real estate firms by 3–6% annually, adjusted for exposures to the market return, size, value, and momentum factors. Moreover, conditional beta estimates reveal that these firms indeed have higher market betas, and the spread between the betas of high and low real estate firms is countercyclical.

We study the economic sources of stock-bond return comovements and their time variation using a dynamic factor model. We identify the economic factors employing a semi structural regime-switching model for state variables such as interest rates, inflation, the output gap, and cash flow growth. We also view risk aversion, uncertainty about inflation and output, and liquidity proxies as additional potential factors. We find that macroeconomic fundamentals contribute little to explaining stock and bond return correlations but that other factors, especially liquidity proxies, play a more important role. The macro factors are still important in fitting bond return volatility, whereas the “variance premium” is critical in explaining stock return volatility. However, the factor model primarily fails in fitting covariances. [ABSTRACT FROM PUBLISHER]

In a recently published paper, Edmans, García, and Norli (2007) reveal a strong association between results of soccer games and local stock returns. Inspired by their work, we propose a novel approach to exploit this effect on the aggregate international level with the following three unique features: i) The aggregate effect does not depend on the games' results; hence, the effect is an exploitable predictable effect. ii) The aggregate effect is based on many games; hence, it is very large and highly significant. We find that the average return on the U.S. market over the World Cup's effect period is -2.58%, compared to +1.21% for all-days average returns over the same period length. iii) Exploiting the aggregate effect is involved with trading in a single index for a relatively long period.

This paper investigates whether comovements between euro area equity returns at national and industry level changed after the introduction of the euro. By adopting a regression quantile-based methodology, we find that after 1999 the degree of comovements among euro area national equity markets was augmented. By explicitly controlling for the impact of global factors, we show that this result cannot be explained by recent worldwide trends. A more refined analysis based on an industry breakdown suggests that the increase in national index comovements is mainly driven by financial, industrial, and consumer services sectors.

Ang, Hodrick, Xing, and Zhang (2006a) show that stocks with high idiosyncratic return volatility tend to have low future returns. This paper further documents that idiosyncratic volatility is inversely related to future earning shocks, and more importantly, that the return- predictive power of idiosyncratic volatility is induced by its information content about future earnings. We examine various explanations of the triangular relation among idiosyncratic volatility, future earning shocks, and future stock returns. Our results show that the idiosyncratic volatility anomaly is not a simple manifestation of previously documented market anomalies related to excessive extrapolation on firm growth, over-investment tendency, accounting accruals, or investor underreaction to earnings news. On the other hand, there is evidence that the idiosyncratic volatility anomaly is related to corporate selective disclosure, and the anomaly is stronger among stocks with a less sophisticated investor base.

We present a dynamic capabilities framework to explain the effective strategic management of the political environment. We argue that the effectiveness of political strategies will be a function of firms' dynamic political management capabilities and propose four firm-level strategies--proactive, defensive, anticipatory, and reactive--for managing the political environment effectively. We develop propositions to explain how particular dynamic capabilities are associated with the effectiveness of alternative political strategies and conclude with suggestions for future research into effective strategic political management.

We develop a one-period model of investor asset holdings where investors have heterogeneous preference for skewness. Introducing heterogeneous preference for skewness allows the models investors, in equilibrium, to underdiversify. We find support for our model's three key implications using a dataset of 60.000 individual investor accounts. First, we document that the portfolio returns of underdiversified investors are substantially more positively skewed than those of diversified investors. Second, we show that the apparent mean-variance inefficiency of underdiversified investors can be largely explained by the fact that investors sacrifice mean-variance efficiency for higher skewness exposure. Furthermore, we show that idiosyncratic skewness, and not just coskewness, can impact equilibrium prices. Third, the underdiversification of investors does not appear to be coincidentally related to skewness. Stocks most often selected by underdiversified investors have substantially higher average skewness especially idiosyncratic skewness than stocks most often selected by diversified investors.

The pricing of corporate debt is still a challenging and active research area in corporate finance. Starting with Merton (1974), many authors proposed a structural approach in which the value of the assets of the firm is modeled by a stochastic process, and all other variables are derived from this basic process. These structural models have become more complex over time in order to capture more realistic aspects of bankruptcy proceedings. The literature in this area emphasizes closed-form solutions that are derived by either partial differential equation methods or analytical pricing techniques. However, it is not always possible to build a comprehensive model with realistic model features and achieve a closed-form solution at the same time. In this paper, we develop a binomial lattice method that can be used to handle complex structural models such as ones that include Chapter 11 proceedings of the U.S. bankruptcy code. Although lattice methods have been widely used in the option pricing literature, they are relatively new in corporate debt pricing. In particular, the limited liability requirement of the equity holders needs to be handled carefully in this context. Our method can be used to solve the Leland (1994) model and its extension to the finite maturity case, the more complex model of Broadie, Chernov, and Sundaresan (2007), and others.

We use a production-based asset pricing model to investigate whether financing constraints are quantitatively important for the cross-section of returns. Specifically, we use GMM to explore the stochastic Euler equation imposed on returns by optimal investment, Our methods can identify the impact of financial frictions on the stochastic discount factor with cyclical variations in cost of external funds. We find that financing frictions provide a common factor that improves the pricing of cross-sectional returns, Moreover, the shadow cost of external funds exhibits strong procyclical variation, so that financial frictions are more important in relatively good economic conditions.

The paper argues that the market significantly overvalues firms with severely underfunded pension plans. These companies earn lower stock returns than firms with healthier pension plans for at least 5 years after the first emergence of the underfunding. The low returns are not explained by risk, price momentum, earnings momentum, or accruals. Further, the evidence suggests that investors do not anticipate the impact of the pension liability on future earnings, and they are surprised when the negative implications of underfunding ultimately materialize. Finally, underfunded firms have poor operating performance, and they earn low returns, although they are value companies. [ABSTRACT FROM AUTHOR]

Many models use noise trader risk and corresponding violations of the Law of One Price to explain pricing anomalies, but include a storage technology in perfectly elastic supply or unlimited asset liability. Storage allows aggregate consumption risk to differ from exogenous fundamental risk, but using aggregate consumption as a factor for asset returns can make noise trader risk superfluous. Using (i) limited asset liability and limited storage withdrawals, or (ii) an endogenous locally riskless interest rate eliminates violations of the Law of One Price. Our main results use only budget equations and market clearing, and require virtually no assumptions about behavior. [ABSTRACT FROM AUTHOR]

We decompose currency returns into (permanent) intrinsic-value shocks and (transitory) expected-return shocks. We explore interactions between these shocks, currency returns, and institutional-investor currency flows. Intrinsic-value shocks are: dwarfed by expected-return shocks (yet currency returns overreact to them); unrelated to flows (although expected-return shocks correlate with flows); and related positively to forecasted cumulated-interest differentials. These results suggest flows are related to short-term currency returns, while fundamentals better explain long-term returns and values. They also rationalize the long-observed poor performance of exchange-rate models: by ignoring the distinction between permanent and transitory exchange-rate changes, prior tests obscure the connection between currencies and fundamentals.

The authors empirically explore the revenue impact of marketing-mix variables and their interactions. The findings include the following: pharmaceutical direct-to-consumer advertising and detailing (sales force) affect demand synergistically, detailing raises price elasticity, and detailing has a higher return on investment than does direct-to-consumer advertising. The authors also discuss other implications and provide future research directions. [ABSTRACT FROM AUTHOR]

I examine the concern that unconstrained real options can lead to escalation of commitment and identify contexts in which escalation of commitment is likely. I argue that these situations fall primarily outside the realm of unregulated for-profit organizations and also that the predictions of agency and attribution theories counter the predictions of the escalation of commitment framework. Finally, I assert that optimality requires flexibility in the timing of the exercise of real options when returns on investment are volatile. [ABSTRACT FROM AUTHOR]

In this paper, we study intertemporal portfolio choice when an investor accounts explicitly for model misspecification. We develop a framework that allows for ambiguity about not just the joint distribution of returns for all stocks in the portfolio, but also for different levels of ambiguity for the marginal distribution of returns for any subset of these stocks. We find that when the overall ambiguity about the joint distribution of returns is high, then small differences in ambiguity for the marginal return distribution will result in a portfolio that is significantly underdiversified relative to the standard mean-variance portfolio.

Prior research has documented positive abnormal stock returns around the announcements of repurchase programs; several explanations of these returns have been suggested, including signaling, free cash flow, and wealth redistributions. This study analyzes abnormal stock, bond, and firm returns around repurchase announcements to examine these hypotheses. We find evidence consistent with both signaling and wealth redistribution. The loss to bondholders is a function of the size of the repurchase, and the risk of the firm's debt. We also find that bond ratings are twice as likely to be downgraded as upgraded after the announcement of the repurchase program. [ABSTRACT FROM AUTHOR]

We investigate the bias in CRSP's Nasdaq data due to missing returns for delisted stocks. We find that the missing returns are large and negative on average, and that delisted stocks experience a substantial decrease in liquidity. We estimate that using a corrected return of 55 percent for missing performance-related delisting returns corrects the bias. We revisit previous work which finds a size effect among Nasdaq stocks. After correcting for the delisting bias, there is no evidence that there ever was a size effect on Nasdaq. Our results are inconsistent with most risk-based explanations of the size effect.

Uniting diverse stakeholders through communication, education or building a collaborative ‘common vision’ for biodiversity management is a recommended approach for enabling effective conservation in regions with multiple uses. However, socially focused strategies such as building a collaborative vision can require sharing scarce resources (time and financial resources) with the on-ground management actions needed to achieve conservation outcomes. Here we adapt current prioritisation tools to predict the likely return on the financial investment of building a stakeholder-led vision along with a portfolio of on-ground management strategies. Our approach brings together and analyses expert knowledge to estimate the cost-effectiveness of a common vision strategy and on-ground management strategies, before any investments in these strategies are made. We test our approach in an intensively-used Australian biodiversity hotspot with 179 threatened or at-risk species. Experts predicted that an effective stakeholder vision for the region would have a relatively low cost and would significantly increase the feasibility of on-ground management strategies. As a result, our analysis indicates that a common vision is likely to be a cost-effective investment, increasing the expected persistence of threatened species in the region by 9 to 52%, depending upon the strategies implemented. Our approach can provide the maximum budget that is worth investing in building a common vision or another socially focused strategy for building support for on-ground conservation actions. The approach can assist with decisions about whether and how to allocate scarce resources amongst social and ecological actions for biodiversity conservation in other regions worldwide.

• Return on investments in land restoration can be increased with an understanding of land potential. • High returns on land degradation avoidance are likely on high value land with low resilience. • Analysis requires an understanding of degradation resistance, resilience. • It also requires understanding likely changes in land values driving future land use. • Ignoring these factors may result in negative returns or even increased degradation. The response hierarchy of "Avoid > reduce > reverse" is increasingly acknowledged as the best strategy for prioritizing actions designed to address land degradation at hectare to national scales. This hierarchy is based on the assumption that the economic return on investment (ROI) will usually be higher for actions that help avoid degradation than for those required to restore already degraded land. While a useful first step, the hierarchy fails to account for how differences in land potential, defined as its potential to sustainably generate ecosystem services, may affect the ROI of actions at each level of the response hierarchy. The objective of this paper is to present a strategy for improving ROI at the landscape scale and above by systematically applying a more holistic understanding of land potential to the identification and prioritization of land investments. This objective is addressed in three sections. The first section explains how the potential short- and long-term resistance and resilience of the land can be used together with its potential productivity to prioritize actions designed to avoid, reduce and reverse degradation. In the second section we explain how this prioritization can be further optimized based on an understanding of degradation risk as indicated by the land's potential to generate relatively high short-term profits under management systems that are likely to increase degradation, or result in degradation of restored land. This potential, and land managers' perception of it, depend on a wide variety of factors including markets, infrastructure, and access to technology. Together these first two sections provide a framework for increasing ROI, while reducing the risk of failure at hectare to national scales. In the final section we briefly describe the Land-Potential Knowledge System (LandPKS), a modular mobile app that makes it possible for virtually anyone with a smartphone to make the land potential determinations necessary to apply the framework described in the first two sections.

In this paper, I aim to explore the effect of good governance on equity returns, and empirically investigate if governance at the country level has asset pricing implications and contributes to the idiosyncrasy of price jumps. Jumps are found to be far less systematic than the smooth (non-jump) component of country price indexes. Hence, if jumps are more idiosyncratic, governance should primarily affect the jump risk component. This is good news for international investors, because diversification provides insurance against jumps. Relying on an equilibrium asset-pricing model in an economy under jump diffusion, I decompose the moments of the returns of international stock markets into a diffusive (systematic) risk and a (idiosyncratic) jump risk part. For a balanced panel of 52 countries, my results suggest that governance is an important determinant of (idiosyncratic) jump risk. Stock markets in poorly governed countries are characterized by higher volatility and more negative return asymmetry, primarily driven by the higher jump risk. Regulatory quality, the government effectiveness and the control of corruption appear to be most important. Results are robust to the inclusion of various controls for other country- or market-specific characteristics. [ABSTRACT FROM AUTHOR]

Duality theory is employed to provide necessary and sufficient conditions for portfolios on the minimum-variance frontier to have positive investment proportions in all assets. These conditions involve the feasibility of portfolios that have non-negative correlation with all assets and positive correlation with at least one. Using these results, several "qualitative" results concerning the signs of investment proportions in efficient portfolios are proved. It is argued that the conditions that ensure all-positive weights in efficient portfolios are intuitively compelling and are not unique to the CAPM. With large numbers of assets, however, the signs of weights in minimum-variance portfolios can be very sensitive to slight departures from these conditions due to, for example, sampling error.

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]

We develop an analytical model to address the question of optimal deposit insurance policy and to examine the impact of deregulation on depositors' welfare and the soundness of the insurance system. We find that the optimal level of regulation depends critically on the functional relationship between risk and return. We show that in general deregulation of bank activities and/or of deposit rate ceilings will involve tradeoff between depositors' welfare and the soundness of the insurance system. Our analysis also indicates that risk-sensitive premium and capital requirement schedules may not be efficient in managing the risk of banks. [ABSTRACT FROM AUTHOR]

This paper provides new tests of the arbitrage pricing theory (APT). Test results appear to be extremely sensitive to the number of securities used in the two stages of the tests of the APT model. New tests also indicate that unique risk is fully as important as common risk. While these tests have serious limitations, they are inconsistent with the APT. [ABSTRACT FROM AUTHOR]

The gain to stockholders from mergers is well documented. However, there is little evidence as to whether the source of the gain is due to synergy or management displacement. Merger is just one of an almost limitless variety of ways in which firms combine resources to accomplish some objective. A joint venture is another. In addition to being of interest as an independent phenomenon, because the original managements of the parent firms remain intact under a joint venture, investigation of wealth gains from joint ventures provides an opportunity to isolate the management displacement hypothesis from the synergy hypothesis as the source of gains in corporate combinations. Our results are 1) there are significant wealth gains from joint ventures, 2) the smaller partner earns a larger excess rate of return while the dollar gains are more equally divided, and 3) the gains, scaled by resources committed, yield “premiums” similar to those in mergers. We are inclined to interpret our results as supportive of the synergy hypothesis as the source of gain from corporate combinations. [ABSTRACT FROM AUTHOR]

A nonparametric statistical procedure is employed to examine the returns to speculators in wheat, corn, and soybeans futures markets. We find that the theory of normal backwardation is supported. Moreover, the presence of the risk premiums to speculators tends to be more prominent in recent years than in earlier years. We also find that large wheat speculators as a whole possessed some superior forecasting ability. The evidence is inconsistent with the hypothesis that commodity futures prices are unbiased estimates of the corresponding future spot prices. [ABSTRACT FROM AUTHOR]

This paper characterizes conditions under which asset returns and consumption are consistent with risk-averse preferences. It is shown that risk aversion is equivalent to "zero arbitrage" on a transformation of the payoff space. The implicit state prices which are dual to this no-arbitrage condition can be interpreted as prices of "pure consumption hedges." This zero-arbitrage restriction implies the usual restrictions associated with nonsatiation. The analysis holds in both complete and incomplete market settings. [ABSTRACT FROM AUTHOR]

Sell-off activities arise when a firm sells part of its assets (e.g., a segment, a division, etc.) but continues to exist in essentially the same form. This study investigates the effect of voluntary sell-offs on stock returns. From a sample of over 1000 sell-off events (first public announcements), the evidence shows that both sellers and buyers earn significant positive excess returns from these transactions. The excess returns earned by buyers are smaller than those earned by sellers. There is also evidence that sell-off announcements are preceded by a period of significant negative returns for the sellers which suggests that the sellers, on average, performed poorly prior to their sell-off activities.

In this paper we extend the multigood futures pricing model of Grauer and Litzenberger [9] to a dynamic discrete time setting. We then test the model using data on futures prices for corn, wheat, and soybeans. The parameter estimates we obtain are similar to those obtained by other researchers using stock return data. The model itself is rejected and we offer some suggestions as to which assumption may be violated. We also give an interpretation to the Hansen-Singleton nonlinear instrumental variables estimation technique used in our empirical work. [ABSTRACT FROM AUTHOR]

Empirical tests are reported for Ross' arbitrage pricing theory using monthly data for U.S. Treasury securities during the 1960-1979 period. We find that mean returns on bond portfolios are linearly related to at least two factor loadings. Multivariate test results, however, are not consistent with the APT. Our sample data in the U.S. Treasury securities market are also not consistent with either version of the CAPM. One-month-ahead forecasts of excess returns using factor-generating models are compared with corresponding naive predictions or predictions using the "market model" with various market portfolios.

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 cross-forecaster 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. [ABSTRACT FROM AUTHOR]
