It is easily demonstrated ex post that international portfolio diversification results in increased returns and reduced risk. However, to determine the value of international diversification as an effective portfolio management strategy, it is necessary to form portfolios based on information available at the time of their composition, and then evaluate the performance of the portfolio in the following months. This is the main focus of our study, which adds several innovations to past research. First, we use daily rates of return on 23 national indices to evaluate the value of international diversification for a Canadian investor. Second, we evaluate the predictive value of the historical variance-covariance matrix vis-à-vis alternative models. Third, we use the Bayes-Stein correction to reduce errors in the historical return vector. Finally, we use a quadratic programming model in order to introduce the effects of constraints on the optimisation process. The results, obtained over the 1986–1989 period, are not in favour of international diversification. Returns on diversified portfolios were often lower than returns on the low-risk Canada market during the low-performance portfolio test periods. In other cases, higher returns on diversified portfolios could not be justified by their higher volatility. It is possible that these results may be partially due to the effects of the market crash in October 1987. Nevertheless, our study brings up many directions for future research. Is international diversification in fact profitable? Is portfolio optimisation appropriate in an international context? Finally, what is the best way to estimate the expected return vector in various markets?  相似文献

In real world markets and business markets in particular, the idea of customized products and services receives increasing attention. A management tool called customer integration has been developed as an approach to master the challenges originating from customization for a supplier. Customer integration competence is the organizational quality that results from this tool after being implemented. Putting this together, we can hypothesize a causal relation between customer integration competence and market success. In order to confirm this hypothesis, the paper presents a conceptualization of customer integration competence. To accomplish this, references are made to competence models from psychology, success factor research and organizational science. The concept was validated through a survey with 78 industry experts from business markets responding. Customer integration competence measured in this way was then contrasted to a second measure capturing market success. Regression analysis supports our hypothesis strongly. Finally, implications for marketing research as well as marketing practice are presented.  相似文献

In this paper, we develop a model to predict the impact of deregulation in the form of relaxing interest rate control on the integration between the mortgage credit market and the general credit market. The model is tested through the examination of the long-term Granger-like equilibrium relationship between mortgage interest rates and general interest rates in the pre-1980 regulated vs. the post-1980 deregulated periods. It is shown that the level of regulation, in the form of targeting general interest rate levels, contributes to the segmentation of the mortgage market from the capital market. To test this model, we compare the relationship between mortgage interest rates and general interest rates around 1980 where major control on interest rate levels in capital markets was lifted. Using Engle and Granger's procedure to overcome the estimation problem from nonstationarity in the interest rate series, we are able to find that the two interest rates were cointegrated after 1980 but not before. More importantly, it appears that the two markets were already integrated before the full development of the secondary mortgage markets between 1984 and 1987. Therefore, we conclude that the bulk of the integration between the mortgage and capital markets was completed as a result of the removal of interest rate controls around 1980, in contrast with previous studies that find integration occurred during the mid-1980s primarily as a result of the rapid development of the secondary mortgage markets.  相似文献

The role of well-functioning markets for development is now widely recognized. However the challenge remains to make these markets benefit the poor and the environment. Increasing attention is being given to the potential role markets can play for agrobiodiversity conservation through product diversification and increasing competitiveness in niche and novelty markets. Several case studies were undertaken that explore the use of market-based approaches to on-farm agrobiodiversity management and livelihood improvement. This paper explores how the theory of collective action can provide a more synthetic understanding of how market chains operate, and the changes that could permit a more equitable distribution of benefits. The case studies illustrate the need for improved trust, mutual understanding of each actor’s involvement, and an agreed process of collective action with a high level of community participation. The cases differ in their degree of collective action, the level of market organization and the ways in which handling, processing, and innovative marketing add value to the agrobiodiversity products. Comparative analysis identified a range of situations in which market development can support agrobiodiversity conservation and livelihoods.  相似文献

This study examines firm profitability differences among “new” multinational enterprises (NMNEs) pursuing geographic diversification into two distinct types of geographic locations based on the development of strategic factor markets. Building on strategic factor markets theory, we propose that firm‐specific advantages of NMNEs contribute differentially to firm profitability because they evolve differently given strategic factor market differences in host compared to home countries. Using a sample of Korean manufacturing MNEs during the 1993–2003 period, we find that geographic diversification into resource‐poorer host countries has a positive relationship with firm profitability, whereas geographic diversification into resource‐richer host countries has a U‐shaped relationship with firm profitability. Our study demonstrates why strategic factor markets—an important and often overlooked contextual factor—matter in exploring rationales for geographic diversification.

The Integration of Commercial Real Estate Markets and Stock Markets   总被引:15,自引:1,他引:14  
This paper tests whether commercial real estate markets (both exchange-traded and non-exchange-traded) are integrated with stock markets using multifactor asset pricing models. The results support the hypothesis that the market for exchange-traded real estate companies, including REITs, is integrated with the market for exchange-traded (non-real-estate) stocks. Moreover, the degree of integration has significantly increased during the 1990s. However, when appraisal-based returns (adjusted for smoothing) are used to construct real estate portfolio returns, the results fail to support the integration hypothesis, although this may reflect the inability of these estimated private market returns to accurately proxy for commercial real estate returns. Interestingly, the growth rate in real per capita consumption is consistently priced in both commercial real estate markets and stock markets, whereas previous studies have found mixed evidence on the role of consumption in explaining ex ante stock returns.  相似文献

This paper examines how demand conditions across alternative markets impact diversification decisions and firm performance by influencing the opportunity costs of deploying non‐scale free capabilities. Using data within the cardiovascular medical device industry, this study shows that: (1) firms with a larger stock of pre‐entry innovation experience are more likely to diversify; (2) firms in a current market with greater relative demand maturity are more likely to diversify; (3) diversification is associated with a performance decrease in the current market; and (4) diversification is associated with a performance increase at the corporate level. These findings shed new light on the self‐selection process of corporate scope, the conceptualization of firm capabilities, and the connection between industry dynamics and resource deployment.

The globalization of markets and industries has fundamentally changed the competitive conditions facing firms. Yet, how globalization has influenced the international diversification strategies of firms is an issue largely overlooked in both the strategic management and international business literatures. This paper develops a theoretical framework to understand how industry globalization, foreign competition, and firm product diversification may influence a firm's choice of its degree and scope of international diversification. Utilizing a panel dataset of U.S. manufacturing firms for the period 1987–99, we provide the first empirical evidence that industry globalization and foreign-based competition are statistically significant factors explaining the degree and scope of international diversification by U.S. firms.

Results of an unobserved effects model on the determinants of inter- and intraregional grain market integration in Russia in comparison to the USA highlights the differences of the mechanisms underlying market integration in each market. Physical trade flows are exclusively dominant in Russia; in contrast, in the United States, additional information flows induced by commodity futures markets play a great role. Policies which improve grain market efficiency in Russia should not only foster investments in transportation and trade infrastructure, but also the development of market information services and commodity futures markets.  相似文献

In this paper we address the issue of whether renewable energy sources can be integrated into power markets if the use of renewable energies is extended at the desired speed. Market integration means that renewable energy sources have to cover their full costs from revenues on competitive markets. In the first part of this paper, we evaluate the long-term revenues of intermittent renewable energy sources using a high resolution power market model. Considering the renewable targets of the German lead study of 2010, we show that due to the merit order effect, intermittent renewable energy sources, such as wind power and photovoltaic, cannot be financed through power markets alone, even if their full costs fall below those of conventional power plants. This is also true for scenarios with high CO2-prices and increasing spot market prices. In the second part of this paper, we discuss whether in the long run additional instruments such as green certificates or capacity markets would allow for a more competitive financing of renewable energy sources. Center stage in the discussion is the question under which circumstances these instruments increase competitive pricing and decentralised market decisions.  相似文献

A review of extant literature reveals various theories on innovation, including technology push, market pull, and an organizational approach. All of these theories have been criticized for their lack of integration and inapplicability to today's competitive environment. An integrated view of innovation has emerged that synthesizes the variables in previous approaches. However, the application of this view has been restricted to investigating the innovation processes within the computer and manufacturing industries, whereas the biotechnology industry has been ignored. This is despite biotech managers' well‐acknowledged thirst for innovation and the ability of biotech to shape the way we live. The present article contributes to the literature by applying an integrated approach to the biotech industry, thereby extending understanding of innovation management beyond the traditional field of inquiry. An integrated approach is of particular relevance to biotech companies, given the complexities of managing the industry's long development cycle and intense collaborative activities. In‐depth interviews with eight organizations in Maryland formed the basis for an investigation into the challenges of managing the innovation process in biotechnology firms. The findings revealed that biotech entrepreneurs are ill prepared to lead their organizations through several transformations necessary along the product life cycle because of their fixation on a technology‐push approach and lack of an understanding of integrated innovation. These leaders also lack the commercialization knowledge necessary to push products to markets, resulting in avoidable delays and loss of productivity. The existing research has dispelled myths associated with biotech. Specifically, it suggests biotech entrepreneurs cannot rely solely on inventions but must invest in a timely application of knowledge to organizational and market forces to take full advantage of the innovation potential associated with the industry. This article presents a conceptual framework for applying the integrated innovation model to biotech firms and makes the case for incorporating market‐oriented mechanisms, building and using appropriate organizational capabilities, developing effective collaborations, and creating parallel interactions as major elements in a general strategy toward the success and improved efficiency of biotech companies. The limitations of current research are discussed, and avenues are highlighted for much‐needed future research into the biotech industry.  相似文献

This paper shows that cross‐border mergers are more likely to occur in industries which serve multiple segmented markets rather than a single integrated market, given that cost functions are strictly convex. The product price rises in the market where an acquisition is made but falls in the other, decreasing the acquisition price of other firms (in contrast to the results in the existing merger literature on integrated markets). Although the sum of consumer surplus across the countries may rise in response to a given acquisition, one of the countries gains at the expense of the other.  相似文献

Imperfect competition, imperfect information, disequilibrium, and rationing all induce vertical integration in relatively straightforward ways. But can vertical integration arise when firms are competitive and markets clear rapidly? This paper demonstrates that a vertical equilibrium can be generated when the intermediate market is subject to external fluctuations and when there are economies of coordination for firms which avoid the market via integration. The vertical equilibrium is one in which some firms will be integrated while some will not, despite the fact that all firms are identical. Thus, one need not conclude that differential degrees of integration within industries are the result of differing circumstances among firms.  相似文献

Based on a sample of 62 multinationals, this paper examines the impact of global diversification strategy on corporate profit performance by integrating the product and the international market dimensions of diversification. The results suggest that the corporate profit performance impact of related and unrelated diversification varies contingent upon the extent of a firm's international market diversification. One important lesson of this work is that both business strategy researchers and managers should review corporate diversification as having distinct yet interactive strategic dimensions—product and international market—and they would do well to recognize both the different and the joint effect of these dimensions on corporate profit performance.  相似文献

The anticipated profits from entry by an established firm into a new market will depend on how incumbents in that market are expected to respond. One possibility, suggested by cases and the literature, is that an incumbent may respond with ‘retaliatory entry’ into the first entrant's ‘home’ market. The model presented here describes conditions under which this can be a credible threat that deters the first entry. When the conditions are such that it is not credible, the paper shows how firms can provide credibility through the establishment of toe‐hold investments in other markets.  相似文献

The study extends research on the geographic scope, product diversification, and performance relationship by exploring both the antecedents and consequences of geographic scope. In so doing, it addresses a fundamental criticism of the geographic scope–performance relationship; namely, that the observed positive relationship between geographic scope and performance is spurious because it is the possession of proprietary assets that is the foundation of superior performance, not expansion into international markets per se. We tested the research model with data on the corporate performance of 399 Japanese manufacturing firms. In the partial least squares analyses used to examine the study’s six main hypotheses, we demonstrate that geographic scope was positively associated with firm profitability, even when the competing effect of proprietary assets on firm performance was considered. Further, we find that performance was not related to the extent of product diversification, although investment levels in rent‐generating, proprietary assets were related to the extent of product diversification.

A review of the literature has revealed that insufficient attention has been paid to the international branding process. Following in-depth interviews with eight manufacturers from South Korea and Taiwan, a stage model of international brand development is therefore proposed. This model is a composite of three extant literatures, i.e., international branding, the Small Business Growth Stage Model, and the Internationalization Process model. The model highlights four successive and progressive stages underpinning international brand development: Pre-international, Lead Market Carrying Capacity, International Branding and Market Succession, and Local Climax. According to the proposed model, firms begin with the development of a strong brand in home markets, then, utilize OEM brands to expand and become familiar with international markets. A gradual decrease in OEM contracts and more concentration on international branding in the three global lead markets (i.e., the USA, Japan, and the EU) follow. The stage model ends with brand development deploying localization in the Third World countries. The article concludes by providing research implications as well as future research directions.  相似文献

International Real Estate Returns: A Multifactor, Multicountry Approach   总被引:3,自引:0,他引:3  
We examine the risk and return characteristics of publicly traded real estate companies from 14 countries over the period 1990 to 2001. Our data are monthly country-level commercial real estate indexes constructed by the European Public Real Estate Association (EPRA). We find substantial variation in mean real estate returns and standard deviations across countries. Using various global- and country-level factor models, we find that there is evidence of a strong global market risk component, measured relative to the Morgan Stanley Capital International world index, in most countries. However, even after controlling for the effects of global market risk, an orthogonalized country-specific market risk factor is highly significant, especially for real estate indexes in Asia–Pacific markets. We find that a country-specific value risk factor has some explanatory power in addition to the country-specific market factor, but U.S.-based market, value and size risk factors do not provide any additional explanatory power. These findings imply that the international diversification opportunities with real estate companies are more complex than previously thought.  相似文献

Firms engage in contractual R&D agreements for several reasons, including product innovation motives, firm performance goals, and technological diversification. This article demonstrates that firms also might enter into external collaborations to penetrate new markets. This study therefore explores both the effects and the strategic risks of contractual R&D agreements and their related knowledge structures for a firm's capacity to diversify into new markets. Drawing on a novel panel data set obtained from 102 Fortune high‐tech firms, the authors demonstrate that strategic alliances enable knowledge‐integrated firms to penetrate new businesses; however, these organizations should be cautious about engaging in licensing‐in agreements, which have negative effects on product diversification.  相似文献
