Strategy implementation and performance in organizations are influenced by its market orientation. Market orientation is the collective of employee behaviors that affects strategy implementation, how an organization interacts with its environment and adjusts to changes within that context. The relationship between market orientation, strategy implementation, and performance is robust across environmental contexts. This study identifies ideal behavioral profiles for organizations seeking to maximize performance by considering the scope and impact of market orientation on strategy implementation. This is accomplished by considering market orientation and strategy profiles in relation to performance in a holistic coalignment perspective, corresponding to competitive contexts characterized by varying degrees of market turbulence and competitive intensity. Important strategic and performance implications of this dynamic are revealed that should be considered by academics and practitioners alike. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Abstract. This study examines whether mandatorily redeemable preferred stock (MRPS) is priced more like debt or equity by (1) investigating its debt and equity characteristics and (2) specifying conditions under which one characteristic would dominate the other. Based on a sample of 113 nonconvertible MRPS issued during 1970 to 1990, our results are consistent with the view that MRPS has both debt and equity characteristics. The debt (equity) feature is more pronounced among nonutility (utility) issues. Within the utility group, we find high (low) rated MRPS issues to be more debt (equity) like. Our results appear to support current MRPS disclosure rules.  相似文献

Recent papers which have examined unit trusts have controlled either for a 'fund size effect' or for the 'small firms effect' in the investment portfolio. The contribution of this paper is an analysis of the 'small firms effect' whilst simultaneously controlling for the 'fund size effect'. We show that the ethical unit trusts have significantly greater exposure than general unit trusts to the 'small firms effect', and that net of this there is no significant evidence of over or under performance by ethical trusts using an adjusted Jensen measure. Using two cross-sectional approaches, we demonstrate that whilst a 'small firms effect' has a role to play in explaining unit trust performance, fund size is not correlated with the financial performance of unit trusts. This cross-sectional analysis also provides some evidence that ethical unit trusts may perform less well than general unit trusts.  相似文献

The purpose of this paper is to selectively review research that addresses capital budgeting decisions in settings characterized by dispersed information and incentive problems. The papers are theoretical; they formulate and analyze models that vary in the number of periods considered, the number of economic actors involved, and the number of alternative projects available. The aims of the review are to describe some of the formulations that have been studied, to highlight their key economic and mathematical properties, to reveal their common economic forces, and to collect and organize their basic results.  相似文献

This paper shows that the firm has an incentive to issue multiple classes of debt that are differentiated by seniority to enhance securityholder tax-timing option values. The analysis establishes that there is at least one mix of senior and junior debt that maximizes the tax option gain from having multiple priority classes of debt. An analytic example provides specifications for the optimal amount of leverage and the optimal mix of senior and junior debt. Relative to the case of only one class of debt, a multiple debt priority structure increases the optimal amount of corporate leverage.  相似文献

Determinants of Industrial Property Value   总被引:3,自引:0,他引:3  
This paper examines the determinants of industrial properly value. We use the factor-analytic linear structural relations (LISREL) model to confront measurement problems associated with related work. A simultaneous test of the effects on property value of factors summarizing physical property, national market, local market, interest rate and location variables is performed. Findings indicate that the value of industrial buildings during 1987–1991 in the Dallas/Fort Worth area is primarily related to local market effects and to physical characteristics and location of the property.  相似文献

In this paper we study the pricing and hedging of options whose payoff is a polynomial function of the underlying price at expiration; so-called ‘power options’. Working in the well-known Black and Scholes (1973) framework we derive closed-form formulas for the prices of general power calls and puts. Parabola options are studied as a special case. Power options can be hedged by statically combining ordinary options in such a way that their payoffs form a piecewise linear function which approximates the power option's payoff. Traditional delta hedging may subsequently be used to reduce any residual risk.  相似文献

This article examines failure rates in de novo S&Ls that initiated operations during the 1980–1986 period. Overall failure rates are similar to those for existing institutions but are found to vary significantly by location, time of charter, and organizational form. Both univariate tests and results from a probability-of-failure model indicate that inadequate capital, economic stress, poor management of higher risk lending allowed by broader powers, and operating inefficiencies contributed significantly to the likelihood of failure. Use of brokered funds and rapid asset growth are also significantly related to failure likelihood. Interestingly, for those S&Ls which eventually failed, rapid asset growth and high proportions of nonperforming assets actually delayed the timing of their failure. We interpret this to be the result of regulatory forbearance. We also find significant differences between the financial characteristics of de novo and non-de novo S&Ls.  相似文献

This paper examines the dynamic behavior of the stock return volatility for Canada, Japan, Germany, and the United Kingdom. The evidence indicates that international stock return volatility is mainly influenced by the U.S. stock return volatility and the exchange rate volatility, supporting the international capital market integration hypothesis. There seems to be some correlation between stock return volatility and macroeconomic volatility, but the effect is relatively weaker. In addition to the economic fundamentals, the noise component is found to be time varying, confirming the AR(MA)CH specifications in the stock return models.  相似文献
