Previous mortgage prepayment and valuation models assume that two mortgage pools with the same observable characteristics should behave indistinguishably. However, even pools with apparently identical characteristics often exhibit markedly different prepayment behavior. The sources of this heterogeneity may be unobservable, but we can infer information about a pool from its prepayment behavior over time. This article develops a methodology for using this information to calculate pool-specific mortgage-backed security prices. Knowledge of these prices is important both for portfolio valuation and for determining the cheapest pool to deliver when selling mortgagebacked securities. We find that unobservable heterogeneity between mortgage pools is statistically significant, and that pool-specific prices, calculated for a sample of outwardly identical mortgage pools between 1983 and 1989, may differ greatly from any single representative price.  相似文献

To adduce empirical evidence of the benefits of board diversity to investors, we examine the relation between board age-diversity and firm value. We examine different factors that are known to influence firm value both in the short-term and long-term horizons:  cumulative abnormal returns, real earnings management, firm innovative activities, and analyst coverage. Our proxy for board diversity is the board age diversity. We find that board age-diversity enhances firm value through different mechanisms; increased firm innovative activities and curtailed real earnings manipulation. We find that board age-diversity has (no) effect on firm value in the long (short) term horizon. Overall, our results emphasize the long-term benefits of board diversity to investors.  相似文献

This article has two objectives. One is to offer a theoretical model to study how the difference in commission structures affects the performance of agents at full-commission firms (e.g., RE/MAX agents) relative to other agents. The other is to provide an empirical test of the relative performance of full-commission agents. We predict that in equilibrium the selling price and the expected time it takes to sell a listing through a full-commission agent are the same as they are with a traditional agent. Our theoretical predictions are supported by our empirical results.  相似文献

Recent contributions to the literature have resulted in a standard modelling of office markets. The models provide considerable insight into the working of office markets. • Nonetheless, a major difficulty is the use of data for a single city or aggregate data for the U.S. The latter implicitly assumes that model structure is invariant across cities. In this article we test for structural differences in office markets by size class. Rental data from REIS Reports for twenty-one metropolitan areas for the time period 1981 to 1990 are used to model office market behavior. Results suggest market outcomes vary by city size, larger markets are better modelled using standard procedures, and Manhattan behaves quite differently from the other markets.  相似文献

Previous studies suggest that a proper fit between business strategy and human resource management can enhance a firm's financial performance. Building on prior findings, this study proposes that an ideal match could occur on the choice of international adaptation strategy and immigrant effect (IE). This match would have a significant effect on firms’ financial performance. The proposed framework is examined using the experience of 121 firms operating across the Greater China region in the home–host and cross-market scenarios. It is found that the extent of adaptation strategy is positively associated with the choice of IE in both home–host and cross-market scenarios and that IE has significant direct and indirect effects on market share and profitability in the cross-market scenario. This study proposes a new strategy–human resource management-performance framework. The findings established provide some implications for researchers and managers.  相似文献

It is documented in the literature that resource deficiency constitutes a barrier to firms’ internationalization. However, small- and medium-sized firms' (SMEs) perceptual barriers to internationalization have received little attention. By highlighting the importance of managerial perceptions in strategic decisions and integrating the resource-based view and the technology acceptance model, this study examines the role of perceived resource deficiency in SMEs’ internationalization. The major finding of this study suggests that perceived resource deficiency in knowledge-based resources constitutes a major perceptual barrier to SMEs’ internationalization. Particularly, perceived resource deficiency in knowledge-based resources has more negative impact on internationalization than does that in other firm-specific resources.  相似文献
