Controlling for the Impact of Variable Liquidity in Commercial Real Estate Price Indices 总被引:6,自引:1,他引:6
Liquidity in private asset markets is notoriously variable over time. Therefore, indices of changes in market value that are based on asset transaction prices will systematically reflect intertemporal differences in the ease of selling a property. We define and develop a concept of "constant-liquidity value" in the context of a model that is characterized by pro-cyclical volume of trading. We then present an econometric model that allows for estimation of both a standard transaction-based price index and a constant-liquidity index. Our application to the NCREIF database reveals that, in the case of institutional commercial real estate investment, constant-liquidity values tend to lead transaction-based and appraisal-based indices in time, and also to display greater volatility and cycle amplitude. The differences can be significant for strategic investment policy viewed from a mean-variance portfolio optimization perspective. 相似文献

The computer industry is changing dramatically thanks to new technologies that facilitate departure from the lock-in strategies pursued by the long-term industry leaders. New, highly competent competitors have entered the market with the resulting lower profit margins. Innovations in hardware and software are continuously introduced, and a rapid, successful introduction in the market is essential to gain a foothold before new contenders erode the opportunity. The selection of the most likely buyers is therefore important to direct the marketing efforts optimally. An international and a regional field study were carried out to identify the profile of organizations and individuals most likely to adopt an innovation in the computer field. These findings coupled with data base marketing techniques seem promising for a higher success rate in reaching the early adopters (lead users), making it possible to establish a first-mover advantage. The suggested approach can be used in other industries in rapid change. 相似文献

Unlike other aspects of the American health experience, there is a current void of information on expensive illness experiences. This paper is designed to fill this void and prrsents an analysis of the incidence and cost of catastrophic illness in the United States. Catastrophic illness is defined as an illness episode for which a person incurs $5,000 or more of medical expenses in a calendar year. This information is used to provide a framework for focusing the debate about catastrophic and national health insurance. 相似文献
