Little attention has been paid in the literature to the impact of different investment horizons on the portfolio compositiondespite its importance to portfolio managers. One exception isthe study by Gunthorpe and Levy (1994) on the U.S. stock market.Our paper extends the same study to the stock markets of Japan,Hong Kong and Korea. Using 40 individual stocks in each market,our results support those of Gunthorpe and Levy (1994) in thatthe composition of an optimal portfolio depends heavily on theinvestment horizon. When the investment horizon lengthens, theproportion of defensive stocks becomes larger while that ofaggressive stocks becomes smaller. 相似文献

Do the Forward Sales of Real Estate Stabilize Spot Prices? 总被引:1,自引:0,他引:1
S. K. Wong C. Y. Yiu M. K. S. Tse K. W. Chau 《The Journal of Real Estate Finance and Economics》2006,32(3):289-304
We examine the effect of forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The
abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90's in Hong Kong allow
us to undertake empirical tests using Hong Kong's real estate data. Our results show that the volatility of spot prices increased
significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased
again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction
of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction
costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able
to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment, thereby shedding
light on the important role of forward housing contracts in providing price expectation information for spot trading. 相似文献

Global sourcing strategy and sustainable competitive advantage 总被引:1,自引:0,他引:1

Global sourcing strategy has been one of the most hotly debated management trends in the last 20 years. In its early years, global sourcing was examined mostly from “in-house” development and procurement perspectives; and in the last several years, research focus has shifted to “outsourcing” activities. Along with this shift from internal to external focus on global sourcing, many researchers and business practitioners have applied a core competency argument to justify increased levels of outsourcing activities on a global basis. Although the beneficial aspects of outsourcing are assumed in most cases, no consensus exists in reality as to the effect of outsourcing. Furthermore, the increased instability of the exchange rate environment in the last several years has also led to increased difficulties in managing globally scattered operations that were once fashionable in the 1980s-90s under the rubric of global strategy. In this article, the authors explore potential limitations and negative consequences of outsourcing strategy on a global scale. 相似文献

There has been copious research work on the development of house price models and the construction of house price indices. However, results in some studies revealed that the accuracy of such indices could be subject to selection bias when using only information from a sample of sold properties to estimate value movements for the entire housing stock. In particular, estimated house price appreciation is usually systematically higher among properties that change hands more frequently. It therefore suggests that the determination of important factors affecting the transaction frequency or intensity of a housing unit should be a more fundamental research question. This paper examines the possible factors that determine the popularity of residential unit by means of a repeated sales pattern. The Poisson regression model and event history analysis techniques are employed to assess the effect of attributes on transaction frequency and intensity. The event history analyses technique can take account of transaction-specific as well as time-dependent covariates, and therefore is recommended for analyzing repeated sales data in a real estate market. All transaction records during the period 1993–2000 from the Land Registry of one of the most popular residential estates in Hong Kong were used to illustrate the method. Unlike a response to favorable transaction price, good quality units do not necessarily inherently display a high transaction frequency. Rather, units of average quality are more likely to be transactionally active. 相似文献

县域农业土地利用适宜性评价与优化研究以山西省原平市为例 总被引:1,自引:0,他引:1
目的 通过对原平市农业产业适宜性的定量评价,并结合土地利用的角度对原平市农业产业进行布局优化。方法 文章基于GIS空间分析和AHP方法,建立农业适宜性评价指标体系,刻画原平市农业产业适宜性指数的空间分布格局,得出适宜性分级图,进一步叠加原平市土地利用数据,进行农业优化布局分析。结果 原平市农业适宜性水平整体较低,只有14.82%的区域适宜和非常适宜农业生产,集中分布于中部平原地区;53.21%的地区基本适宜农业生产,主要分布于东部丘陵和西部山区;31.97%的地区不适宜农业发展,主要分布于西部山区;同时,在不适宜农业生产的地区中约有15.3%的土地被开垦为耕地,限制了该市整体农业生产效率的提高。结论 与传统的土地适应性相比,该研究嵌入了社会经济因子和管理水平的影响分析,使得研究结果更贴合实际。如何进一步挖掘更全面表征气候、生态、社会经济等影响因素,构建更加全面的适宜性评价指标体系,制定区域有别、因地而异的评价体系标准,是加强农业土地适宜性评价科学性和准确性的有利保障。 相似文献

This article investigates the issue of commitment by a durable goods monopolist. Two models of the interaction between durability, recycling, and market power are compared. The two differ according to the ability of the seller to credibly commit to a given sales strategy. This article takes the standard durable goods monopoly model, extends it to allow for depreciation, and compares the monopoly markup with Swan's predicted markup for a recycled good. The difference between the two models is shown to reduce to a single parameter in the markup equation. 相似文献

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

This paper contributes to the understanding of the executive team dynamic managerial capabilities by developing theory about the interplay between the firm's dominant logic and dynamic managerial capabilities (including managerial human capital, social capital, and cognition). We underscore the criticality of the two key CEO‐level functions: configuration and orchestration of senior executive team dynamic capabilities. We develop theory on how these functions create and sculpt the management team's absorptive capacity, which in turn shapes the team's adaptive capacity. We present theory about the distributed nature of efforts for organizational renewal where CEO's dynamic managerial capabilities in concerto with senior executive managerial capabilities will drive top management's ability to revitalize the firm's dominant logic and to achieve evolutionary fit.

With the changing way people live, communicate, and work, enterprises are striving to shift their existing business model into a “self‐tuning” one. Enterprises are becoming more agile, adaptive, and ambidextrous in order to boost innovation in the current digital transformation era. Nowadays, “digital innovation” is closely associated with Industry 4.0 enablers and smart enterprises. Prior research has shown that while multinational enterprises—across many sectors—have already embraced the aforementioned advancements, their adoption by small and‐medium‐sized enterprises (SMEs) has so far taken place mainly in the manufacturing sector. Thus, based on a sample of 280 self‐tuned smart manufacturing SMEs and having utilized the structural equation modeling (SEM), this study was aimed to investigate how digital innovation is influenced by the three pillars of self‐tuning models—agility, adaptation, and ambidexterity. Our paper has focussed on the digital systems in which SMEs, spurred by networking and open innovation solutions, operate and innovate in response to external triggers, displaying a balance between exploration and exploitation, and a strong agile capacity. 相似文献
