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

In many developing countries, the potential benefits from adopting a transgenic variety developed by a multinational corporation are limited by the crop’s small production base. This paper presents an ex-ante evaluation of the economic impact of herbicide resistant transgenic rice in a small developing country, Uruguay. To fully account for the multinational’s market power, the firm’s seed markup is assumed to affect the adoption rate for the variety. Stochastic simulation techniques are employed to understand how potential benefits may vary with changes in technology, yield, costs, and adoption parameters. The results indicate a $1.82 million mean net present value for producers from the development and utilization of transgenic rice in Uruguay and $0.55 million for the multinational. These relatively small multinational firm benefits suggest that a firm will not undertake significant efforts to develop transgenic varieties adapted to local conditions without either strategic partnerships with local institutions or access to wider regional markets. 相似文献

This paper examines the influence of bargaining power and property class on the prices of heterogeneous goods. Specifically,
it explores the impact of buyer and seller characteristics on the transaction prices of office properties. The empirical model
is based on the work of Harding, Rosenthal, and Sirmans (2003), which developed a method to distinguish between the impact of buyer and seller attributes on bargaining power and the choice
of otherwise unidentified price effects (i.e., property class) in the context of hedonic price models. The data set contains
information on transaction prices of office properties in Cook, DuPage, and Lake Counties, Illinois from 1995 to 1997. The
results reveal systematic differences in bargaining power and property class for certain groups of buyers and sellers contained
within the sample. 相似文献

It is well established that house prices are dynamic. It is also axiomatic that location influences such selling prices, motivating our objective of incorporating spatial information in explaining the evolution of house prices over time. In this paper, we propose a rich class of spatio-temporal models under which each property is point referenced and its associated selling price modeled through a collection of temporally indexed spatial processes. Such modeling includes and extends all house price index models currently in the literature, and furthermore permits distinction between the effects of time and location. We study single family residential sales in two distinct submarkets of a metropolitan area and further categorize the data into single- and multiple-transaction observations. We find the spatial component is very important in explaining house price. Moreover, the relative homogeneity of homes within the submarket and the frequency with which homes sell affects the pattern of variation across space and time. Differences between single and repeat sale data are evident. The methodology is applicable to more general capital asset pricing when location is anticipated to be influential. 相似文献

Asset-backed securitization (ABS) is a relatively new financial instrument in Singapore's capital market, which has been accepted by developers (originators) as an alternative source of financing. Credit assessment and rating requirements have not been imposed on the ABS bond issues. Default-risk evaluation has also been understated, if not omitted, in the process of structuring ABS deals. This is the first study that applies a theoretical default-risky swaps valuation model to evaluate credit risks in ABS bonds in Singapore. The Monte-Carlo simulation results, based on the Century Square shopping mall ABS case, show significant effects of the changes in rental volatility and default-free interest rate volatility on the default-risk premium of swap. More specifically, an increase in the rental volatility reduces the default-risky swap values significantly. However, an increase in the instantaneous default-free interest rate volatility increases the default-risk premium of swaps, and this effect is only observed in the high default-free interest rate volatility regime (above 20 percent). The results suggest that the rental dynamics of the securitized real estate are critical in determining the default risks of ABS deals. The fixed-rate (coupon yield) and floating-rate (rental cash flows) should therefore be adequately determined to reflect the default risks, which may be caused by the rental dynamics of the securitized real estate. 相似文献

Based on a purely rank-oriented approach, this empirical study analyzes to what extent superior firm size in German life industry
generally translates into corporate advantages for the companies concerned. It turns out that while modest advantages with
some criteria are measurable, any such benefits are usually outweighed by unquantifiable factors unrelated to firm size. Confining
the study to a highly homogeneous subgroup of life insurers, however, reveals substantial corporate advantages in a number
of areas, thereby confirming well-established theoretical reasoning. 相似文献

在实施RCM项目时,重点工作放在RCM分析和开发一个适当的RCM模式。但是实施RCM的计划和准备工作开始时,就觉得这项工作过分复杂,并且颇难处理。准备工作屡次被延迟,并且增加了活动次数和资源。工作进度的延迟对这个项目产生了一些影响。例如,项目领导人员有了变动、培训和教育工作要进行多次。在计划和准备阶段可以观察到以下一些问题。 相似文献

The average cost of a sales call has declined approximately 15% over the past decade, while average salesperson compensation has doubled. These statistics illustrate an important benefit of technology: salespeople are more productive. To better understand the impact technology has played on sales and sales management, this paper examines the impact of sales technology from four perspectives: the salesperson, the field sales manager, the sales executive, and the customer. Noting that the needs and evaluations of technology vary, depending upon the functional position and viewpoint, a research agenda is offered that reflects these various perspectives. 相似文献
