Frictions, Heterogeneity and Optimality in Mortgage Modeling   总被引:1,自引:0,他引:1  
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework.  相似文献

In Italy, public expenditure reduction is achieved through a revision of social security and health care programs. In particular, public health expenditure control has been implemented through a reform that imposes more stringent budget rules to local governments and a considerable reduction in grants-in-aid from the central government. This paper investigates empirically whether the response to this decrease in categorical lump-sum grants from the central to local governments results in an asymmetric response to intergovernmental grants. Hard budget and soft budget constraint hypotheses are estimated by using a sample of cross-sectional and time observations covering the 20 Italian regions over the period 1989–1993. The main finding is the existence of a standard and a super flypaper effect in both models. The introduction of the soft-budget constraint hypothesis results in a stronger effect of grants and a lower response of own resources which shows that local governments prefer to incur some deficit instead of reducing health care expenditure.  相似文献

The motorcycle industry in Italy offers fertile ground for anyone interested in developing a better understanding of the role innovation plays in enhancing a firm's competitive position. This industry includes both domestic and Japanese firms, with companies ranging from high-volume manufacturers to specialty or niche producers. Firms trying to gain a competitive edge in this crowded field must contend with not only advances in product and process technology, but also the whims of fashion. In a survey of top-level marketing and product development managers from eight leading firms in the Italian motorcycle industry, Moreno Muffatto and Roberto Panizzolo explore the innovation models these firms employ to enhance their competitive position. Their study has the following objectives: categorizing the various competitors in terms of their product and market strategies and their product development and innovation strategies; highlighting differences between the methods of Italian and Japanese firms competing in this market; analyzing the relationships between firms, as well as the roles suppliers play in the various innovation strategies; and identifying the various organizational models employed by the firms in this industry. Different product and market strategies are identified on the basis of three variables: total production volume, the number of different products offered, and the number of different engine capacities offered. Using these variables, the companies in the study are categorized as volume producers, specialists, or niche specialists. The firms are further differentiated on the basis of the relative emphasis each places on product technology and design, product innovation, product variety, and time-based competition. In the firms studied, partnerships play a key role in new product development. Nearly every firm participates in joint projects, most often involving development of either an entire vehicle or an engine. Other partnerships involve firms in countries that offer emerging markets for the motorcycle industry. Organizational structures and strategies employed by the volume producers in this study include: the large product leader, who oversees concept definition and product planning; the project leaders group, which coordinates all phases of development, including activities assigned to external groups; the project managers matrix, a matrix organizational structure with a strong product orientation; and the business unit program manager, who oversees all projects within an independent business unit.  相似文献

The American corporate financing system, unlike that of most other countries, has not been organized around a set of “universal banks” that perform a variety of functions for their clients. Indeed, the distinguishing feature of American financial history is the number and variety of financial intermediaries, and their relationships with corporations (and one another). Besides commercial banks, there are investment banks, insurance companies, venture capitalists, commercial paper dealers, mutual funds, and many others. The economic role of such intermediaries is to reduce market frictions such as “asymmetric information” and “agency problems” that otherwise raise the cost of outside capital for U.S. companies. This article views the changing menu of such intermediaries and their networks as the driving force behind the evolution of American corporate finance. U.S. financial history is seen as a series of institutional and financial innovations designed in large part to work around costly restrictions on relationships–particularly, limits on the scale and scope of U.S. banks–that do not exist in most other countries. In terms of its success in reducing the information and control costs of corporate finance, the history of the American financial system includes periods of significant progress as well as major reversals. Three relatively successful periods– the early 19th-century in New England, the “incipient” universal banking of the 1920s, and modernday financial capitalism–are separated by periods of drastic reductions in the menu of financial relationships– particularly the Great Depression and its 20-year aftermath. Besides new financial claims like preferred stock and new intermediaries such as venture capitalists, another important innovation is new forms of cooperation among intermediaries– especially among banks, venture capitalists, trusts, pensions, and investment banks–that have enabled the U.S. financial system to provide some of the key advantages of universal banking systems. Some of the largest U.S. commercial banks today can be viewed as positioning themselves to play a central coordinating role in these new coalitions of intermediaries. In so doing, they may become the platform for a distinctively American universal banking system.  相似文献

Price bubbles provide a unique opportunity to study the financial acumen of shareholders. We focus on the 1720 South Sea episode as experienced by the Royal African Company whose stock was more speculative than other joint stocks. During 1720 the company had a new large stock issue. This paper examines the financial acumen of those women who traded senior and engrafted stock across 1720. We find that depending on the pricing regime, these women at worst broke even on their activities or had positive speculative gains. Our findings are consistent with a growing literature on the positive link between gender, capital gains and financial markets.  相似文献

Prior research over several decades has catalogued many positive motives underlying firms' decisions to engage in joint ventures and other forms of alliances. In this empirical analysis, we investigate whether agency problems brought about by the separation of ownership and control also stimulate the development of firms' joint venture portfolios. By focusing on joint ventures, as opposed to diversification in general or acquisitions, we address the recent debate on agency theory's domain. Results from a sample of U.S. manufacturing firms' alliance portfolios offer supporting evidence, and comparable findings are obtained for international and domestic joint ventures. Agency hazards are also found to bring about extensions of firms' nonequity alliance portfolios in both the international and domestic settings. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

The objective of this paper is to evaluate the impact on bank credit exposures to small- and medium-sized Spanish firms of the current proposal for reform of the 1988 Capital Accord using information from the Spanish Credit Register. Capital requirements for exposures to those firms, according to the various revisions of the proposed capital reform (from the January 2001 consultative document to the April 2003 one), are calculated to analyze whether the existing pattern of bank financing of small- and medium-sized firms might be altered. Finally, the incentives for individual banks to adopt the advanced internal ratings-based approach proposed by Basel II are evaluated.  相似文献

The impact of monetary policy on asset prices   总被引:2,自引:0,他引:2  
Estimating the response of asset prices to changes in monetary policy is complicated by the endogeneity of policy decisions and the fact that both interest rates and asset prices react to numerous other variables. This paper develops a new estimator that is based on the heteroskedasticity that exists in high-frequency data. We show that the response of asset prices to changes in monetary policy can be identified based on the increase in the variance of policy shocks that occurs on days of FOMC meetings and of the Chairman's semi-annual monetary policy testimony to Congress. The identification approach employed requires a much weaker set of assumptions than needed under the “event-study” approach that is typically used in this context. The results indicate that an increase in short-term interest rates results in a decline in stock prices and in an upward shift in the yield curve that becomes smaller at longer maturities. The findings also suggest that the event-study estimates contain biases that make the estimated effects on stock prices appear too small and those on Treasury yields too large.  相似文献

The business models of banks are often seen as the result of a variety of simultaneously determined managerial choices, such as those regarding the types of activities, funding sources, level of diversification, and size. Moreover, owing to the fuzziness of data and the possibility that some banks may combine features of different business models, the use of hard clustering methods has often led to poorly identified business models. In this paper we propose a framework to deal with these challenges based on an ensemble of three unsupervised clustering methods to identify banking business models: fuzzy c‐means (which allows us to handle fuzzy clustering), self‐organizing maps (which yield intuitive visual representations of the clusters), and partitioning around medoids (which circumvents the presence of data outliers). We set up our analysis in the context of the European banking sector, which has seen its regulators increasingly focused on examining the business models of supervised entities in the aftermath of the twin financial crises. In our empirical application, we find evidence of four distinct banking business models and further distinguish between banks with a clearly defined business model (core banks) and others (non‐core banks), as well as banks with a stable business model over time (persistent banks) and others (non‐persistent banks). Our proposed framework performs well under several robustness checks related with the sample, clustering methods, and variables used.  相似文献
