Real estate return correlations: Real-world limitations on relationships inferred from NCREIF data

Correlation estimates for returns between individual properties are subject to large inherent uncertainties due to limits on the amount of data that is likely to be available for the foreseeable future. After allowance for correlation sampling error, it is impossible to distinguish on an ex ante basis between the risk-reduction capabilities of mean-variance portfolio selection models and naive diversification without regard to property type or geographical location. The naive portfolio diversification strategies of typical institutional real estate portfolio managers are rational responses to limitations on the informational content of statistical analyses of historical real estate data.     

Financial statement data in assessing the future potential of a technology firm: The case of Nokia

The paper introduces a financial statement method to assess the future potential of a firm. First, the last strategic steady phase is identified. Second, growth rate for total expenditure is estimated (growth process). Third, the revenue generating potential of total expenditure is evaluated by a distributed lag function (revenue-generating process). This function is used to recalculate expenses and assets using alternative depreciation theories. Third, financial behavior is modeled by analyzing financial assets, taxation, interest expenses and revenues, and dividends (financial process). Fourth, these processes are used to assess the future potential. The method is illustrated by the case of Nokia for the period 1990-2000.     

Sources of gains from international portfolio diversification

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.     

Technological diversity,related diversification,and firm performance

Previous findings that related diversification creates value have been called into question over concerns about methodology and measures. Reviewing existing theory to consider how a firm's knowledge base interacts with its product market activity, I address several of these concerns by creating a measure of technological diversity based on citation‐weighted patents. The measure indicates a firm's opportunity for corporate diversification based on economies of scope in valuable knowledge assets, is defined for both single‐ and multibusiness firms, and is not correlated with more fundamental aspects of diversification, such as the number of businesses in the corporate portfolio. Evidence from a large sample of firms shows the positive relationship between diversification based on technological diversity and market‐based measures of performance, controlling for R&D intensity and capital intensity as further indicators of the type of assets underlying diversification. Results hold when controlling for the endogeneity of diversification and performance in a cross‐sectional sample or when controlling for unobserved factors using panel data.

Market orientation and customer satisfaction: Evidence from British machine tool industry

This paper examines empirically the relationship between market orientation and business performance in the context of British machine tool industry. An industry-specific market orientation scale was developed. Factor analysis revealed that there were four latent dimensions underlying the market orientation: customer orientation, competitor orientation, departmental responsiveness, and customer satisfaction orientation. Findings suggest that customer orientation and customer satisfaction orientation have a stronger impact on performance than the other dimensions, and that competitor orientation has a U-shape relationship with performance. Departmental responsiveness did not appear to be significantly related to the business performance. Managers could use the multidimensional conceptualization to develop particular kinds of orientations required for better performance.     

Inter‐temporal economies of scope,organizational modularity,and the dynamics of diversification

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.

Organizational learning and market orientation: interface and effects on performance

This paper discusses the relationship between market orientation and organizational learning and, in particular, the former's contribution to the generation of double-loop learning. Although prior contributions on this topic have been controversial, the authors, departing from the principles of RBV, consider market orientation a resource capable of generating higher order organizational learning and, in this way, capable of additionally reinforcing firms' sustainable competitive advantage. The empirical study provides evidence on the existing relationship between a firm's learning and market orientation degree and the organization's economic and non-economic results. Findings indicate that learning orientation stimulates the market-oriented behavior and that it also positively affects the establishment of long-term relationships with strategic clients. Contrary to prior research a significant and positive effect on business performance is only contrasted in the case of market orientation.     

Firm orientations, innovativeness, and business performance: Advancing a system dynamics view following a comment on Hult, Hurley, and Knight's 2004 study

Hult, Hurley, and Knight's [Ind. Mark. Manage. 33 (2004) 429.] study reports correlations for each of the three subfactors of market orientation (competitor orientation, customer orientation, and interfunctional coordination) and innovativenss. However, their report fails to discuss the nature of these relationships. Such findings are worthy of discussion because they support prior evidence demonstrating the centrality of customer orientation in linking competitor orientation and interfunctional coordination with both innovativeness and business performance. Also, the finding that interfunctional coordination relates strongly with innovativeness supports the paradigm shift toward relationship marketing. The point needs mentioning that several different (more than one) standardized effects, structural equation models explain similar amounts of variance of business performance besides the models that Hult et al. examine. Thus, the implication by Hult et al. (p. 436) that “…learning orientation has no significant direct effect on performance” is accurate only for the model tested (shown in their Fig. 2). Applying the “quick clustering” method helps to inform interpretation when nearly all relationships among variables are statistically significant. The present article includes a proposal for advancing from one-directional structural equation modeling of innovativeness and business performance to system dynamics modeling that includes real-world feedback loops.     

寿险公司的业务同质化与风险联动性

单家机构之间的业务趋同是否是金融业系统性风险的一个来源？近些年中国单家寿险公司的产品分布和地理分布均更加分散,但是公司之间的产品分布和地理分布均有“同质化”趋势,且公司之间在赔付风险、投资风险和破产风险上的联动性均提高。对此,本文分析了寿险公司业务同质化引起风险联动性的机理,探讨了几种可能的效应。基于公司配对样本,并从时间上和地理上引入工具变量处理业务同质度的内生性,发现:(1)当两家寿险公司的产品分布从完全差别到完全相同时,它们的投资风险联动性和破产风险联动性均将提高十几个百分点;(2)产品同质度对赔付风险联动性没有显著影响;(3)地理同质化对3种风险联动性均没有显著影响。
