We examine the acquisition and joint venture strategies of U.S. banks from 1980 to 1998 to diversify into non-banking sectors. We find that the market responds favorably to both types of expansions, with the gains being shared between acquiring banks and their targets and venture banks and their non-bank partners, respectively. Acquisitions expose acquiring banks to significant increases in nonsystematic, market, and total risk, while joint ventures result in significant decreases in the nonsystematic and total risk measures for participating banks. Our results suggest that product-market expansions, in general, provide U.S. banks with value-enhancing opportunities, and that joint ventures may improve both the return and risk characteristics of the partner banks.  相似文献

This article deals with the status of consumer research after nearly twenty years of emphasis. There is a brief history of the subject, an analysis of the number and type articles being published, and an assessment of the direction consumer behavior may take in the future. *** DIRECT SUPPORT *** A00BV020 00002  相似文献

Adjoint methods have recently gained considerable importance in the finance sector, because they allow to quickly compute option sensitivities with respect to a large number of model parameters. In this paper we investigate how the efficiency of adjoint methods can be exploited to speed up the Monte Carlo-based calibration of financial market models. After analyzing the calibration problem both theoretically and numerically, we derive the associated adjoint equation and propose its application in combination with a multi-layer method, for which we prove convergence to a stationary point of the underlying optimization problem. Detailed numerical examples illustrate the performance of the method. In particular, the proposed algorithm reduces the calibration time for a typical equity market model with time-dependent model parameters from over three hours to less than ten minutes on a usual desktop PC.   相似文献

This study examines the effect of firm-level corporate governance on the cost of equity capital in emerging markets and how the effect is influenced by country-level legal protection of investors. We find that firm-level corporate governance has a significantly negative effect on the cost of equity capital in these markets. In addition, this corporate governance effect is more pronounced in countries that provide relatively poor legal protection. Thus, in emerging markets, firm-level corporate governance and country-level shareholder protection seem to be substitutes for each other in reducing the cost of equity. Our results are consistent with the finding from McKinsey's surveys that institutional investors are willing to pay a higher premium for shares in firms with good corporate governance, especially when the firms are in countries where the legal protection of investors is weak.  相似文献

We show that individual investors over‐extrapolate from their personal experience when making savings decisions. Investors who experience particularly rewarding outcomes from 401(k) saving—a high average and/or low variance return—increase their 401(k) savings rate more than investors who have less rewarding experiences. This finding is not driven by aggregate time‐series shocks, income effects, rational learning about investing skill, investor fixed effects, or time‐varying investor‐level heterogeneity that is correlated with portfolio allocations to stock, bond, and cash asset classes. We discuss implications for the equity premium puzzle and interventions aimed at improving household financial outcomes.  相似文献

Abstract:  Prior research documents that US firms write off large in-process research and development charges (IPRD) for acquisitions, possibly overstating the current period expense to inflate future earnings. Consequently, in 1998, the US Securities and Exchange Commission (SEC) began scrutinizing IPRD charges. We use pre-acquisition R&D expenses of 144 target firms as a benchmark for assessing whether IPRD charges are appropriate. Overall, the results suggest that most firms during our sample period were not overly aggressive in expensing IPRD–especially for acquisitions subsequent to the SEC's scrutiny. The results also indicate that the SEC's intervention reduced the frequency of overstated IPRD charges.  相似文献

Marketing decisions are particularly vulnerable to legal rulings made in both the courts and the legislatures. The effective management of those legal implications challenges the modern marketing professional. Grasping marketing’s overall legal environment, including its governing case law, regulatory statutes and future trends, is essential. This review will provide analysis of recent court cases and legislation with particular emphasis on creatively assisting the marketer’s management of the legal factor.  相似文献
