This paper investigates the benefits of allowing households to compensate the portfolio distortion due to their housing consumption through investments in housing price derivatives. Focusing on the London market, we show that a major loss from over-investment in housing is that households are forced to hold a very risky portfolio. However, the strong performance of the London housing market means that little is lost in terms of expected returns. Even households with limited wealth are better off owning their home rather than renting and investing in financial assets, as long as they are willing to face the financial risk involved. In this context, access to housing price derivatives would benefit most poor homeowners looking to limit their risk exposure. It would also benefit wealthier investors looking for the high returns provided by housing investments without the costs of direct ownership of properties. Comparisons with French, Swedish and U.S. data provide a broader perspective on our findings. 相似文献

Strategic Internet application trends in supply chain management 总被引:1,自引:0,他引:1
Richard A. Lancioni Author Vitae Michael F. Smith Author VitaeAuthor Vitae 《Industrial Marketing Management》2003,32(3):211-217
The Internet is evolving as a powerful force in the new marketplace where the nexus of competition has changed from individual firms to efficient supply chain networks both between firms and within industries. This study explores Internet adoption patterns and operational applications in US supply chain networks. The data reveal that the integration of the Internet into supply chain management applications has increased and has moved away from indiscriminate application of novel Internet technologies towards becoming a focused endeavor with precise expectations and measurable goals. Specifically, the study finds that Internet usage within supply chains is maturing as evidenced by enhanced and increased productivity, reduced costs and increased profit for participating firms. 相似文献

Measures developed for the analysis of corporate diversification have become fundamental to a broad range of strategy research. This paper examines the content validity of the two most widely used continuous measures of related diversification—the related component of the entropy index and the concentric index—and raises fundamental questions about their validity as indicators of portfolio relatedness. These questions are not driven by the use of SIC data for estimation of the indexes; they involve validity problems intrinsic to the construction of the measures. The related component of entropy and the concentric index are sensitive to features of corporate portfolio composition that may not be directly linked to portfolio relatedness. These sensitivities can create important ambiguities in strategy research. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

Bank Risk, Capitalization, and Operating Efficiency 总被引:1,自引:0,他引:1
A simultaneous equation framework is used to test hypotheses about the interrelationships among bank interest rate and credit risk-taking, capitalization, and operating efficiency. A positive effect of inefficiency on risk-taking was found and supports the moral hazard hypothesis that poor performers are more vulnerable to risk-taking than high performance banking organizations. A positive effect of inefficiency on the level of capital is attributable to regulatory pressure on underperforming institutions. At the same time, firms with more capital are found to operate more efficiently than less well-capitalized banking organizations. A U-shaped relationship is detected between inefficiency and loan growth, indicating that operating efficiency improves at a decreasing rate as loan growth rate increases. This supports the hypothesis that entrenched managers who pursue a growth objective to enhance their own wealth tend to operate inefficiently. 相似文献

This paper examines the effects of policy coordinationin a two-country world with endogenous growth and imperfect capitalmobility. Redistribution is financed by a source-based capital-incometax. Comparing the cases in which countries do and do not coordinatetheir fiscal policies, it is shown that redistribution can beinefficiently high if fiscal policies are not coordinated. Thisis because the negative effects of fiscal policy on home savingsaffect economic growth abroad by inducing a decline in foreigninvestment. This externality can dominate the well-known tax-baseexternality. 相似文献
