Fussing and fuming over Fannie and Freddie: how much smoke, how much fire?

The roles of Fannie Mae and Freddie Mac have become increasingly controversial in the modern world of residential mortgage finance. The authors describe the special features of these two companies and their roles in the mortgage markets and then discuss the controversies that surround the companies and offer recommendations for improvements in public policy.

Technological change, financial innovation, and diffusion in banking

This paper discusses the technological change and financial innovation that commercial banking has experienced during the past twenty-five years. The paper first describes the role of the financial system in economies and how technological change and financial innovation can improve social welfare. We then survey the literature relating to several specific financial innovations, which we define as new products or services, production processes, or organizational forms. We find that the past quarter century has been a period of substantial change in terms of banking products, services, and production technologies. Moreover, while much effort has been devoted to understanding the characteristics of users and adopters of financial innovations and the attendant welfare implications, we still know little about how and why financial innovations are initially developed.Technological innovations

Empirical studies of financial innovation: lots of talk, little action?

This paper reviews the extant empirical studies of financial innovation. Adopting broad criteria, the authors found just two dozen studies, over half of which (fourteen) had been conducted since 2000. Since some financial innovations are examined by more than one study, only fourteen distinct phenomena have been covered. Especially striking is the fact that only two studies are directed at the hypotheses advanced in many broad descriptive articles concerning the environmental conditions (e.g., regulation, taxes, unstable macroeconomic conditions, and ripe technologies) spurring financial innovation. The authors offer some tentative conjectures as to why empirical studies of financial innovation are comparatively rare. Among their suggested culprits is an absence of accessible data. The authors urge financial regulators to undertake more surveys of financial innovation and to make the survey data more available to researchers.Financial modernization ; Banks and banking ; Patents ; Securities

Emerging competition and risk-taking incentives at Fannie Mae and Freddie Mac

This paper examines two major forces that may soon increase competition in the U.S. secondary conforming mortgage market: (1) the expansion of Federal Home Loan Bank mortgage purchase programs and (2) the adoption of revised risk-based capital requirements for large U.S. banks (Basel II). The authors argue that this competition is likely to reduce the growth and relative importance of Fannie Mae and Freddie Mac and hence their franchise values and effective capital. Such developments could, in turn, lead to more risky behaviors by these two GSEs. It is this last consequence that warrants greater regulatory awareness.

The Federal Home Loan Bank system : the "other" housing GSE.

Founded in 1932, the twelve Federal Home Loan Banks (FHLBs) have historically provided long-term funding to specialized mortgage lenders. But legislative changes in the wake of the 1980s’ thrift crises spurred the FHLBs to expand in both size and scope. For example, FHLB balance sheets now also include a substantial investment in mortgages and mortgage-backed securities, and the attendant interest rate risk has created financial and accounting difficulties at some of the FHLBs. ; Like Fannie Mae and Freddie Mac, the FHLB System is a government-sponsored enterprise that funds itself largely with federal agency debt obligations that investors perceive to be implicitly guaranteed by the U.S. government. This article identifies some differences in risk-taking incentives between the cooperatively owned FHLB System and investor-owned Fannie Mae and Freddie Mac. ; Cooperative ownership itself does not reduce FHLB risk-taking incentives because, unlike many mutuals, the FHLB System does not bundle its equity and debt claims. Also, the joint-and-several liability provision in the FHLBs’ consolidated debt obligations and a lack of equity market discipline may heighten FHLB risk-taking incentives. However, the FHLBs cannot avail themselves of equity-based managerial compensation, which create high-powered risk-taking incentives in investor-owned firms. Thus, it is unclear whether the FHLBs’ risk-taking incentives are necessarily weaker than Fannie Mae’s and Freddie Mac’s.Federal home loan banks

From the "high ground" of policy to "the swamp" of professional practice: the challenge of diversity in teaching labour studies

This case study examines the development the diversity management skills of Higher Education students, in the context of the authors' motivation for exploring diversity and an examination of material developed by academics and practitioners from both the United Kingdom and USA. Four elements of the focus course are then presented: student development, learning methods, assessment and student performance. Data from student questionnaires and quotations from students’ reflections on their learning are then analysed. This demonstrates that they can operate with a dual perspective, by both "dissolving differences" and "valuing differences" as an effective means of managing diversity

From bench to bedside: Tracing the payback forwards from basic or early clinical research – A preliminary exercise and proposals for a future study

EXECUTIVE SUMMARY Chapter 1 : Introduction • The members of the research team from HERG and the Wellcome Trust have conducted previous studies showing that it is possible both to assess the payback from applied health research, and to use bibliometrics to trace the links between generations of research and clinical guidelines. In another of the team’s studies, however, it proved difficult to replicate the major study by Comroe and Dripps (1976) that had identified clinical advances and then worked backwards to show that they had relied on earlier basic research. Therefore, the study reported here sets out to use the methods developed in our previous studies of payback to undertake analysis that starts with more basic or early clinical research and traces the research lines forwards to clinical applications. Whilst this preliminary study involved preparation for a future large-scale study, it was hoped that it would also provide an interesting case study. • Starting with the research outputs of one team 20 years ago, called the 1st generation papers, the preliminary study has three main elements: standard bibliometric analysis through several generations of papers; categorisation of the citations; and qualitative analysis using questionnaires, critical pathway analysis and interviews to trace the impact of the 1st generation of research. • Diabetes and cardiology were suggested as possible topics on which to base the study. Initial reviews identified two bodies of research in diabetes as being potentially suitable for reasons such as the continuing activity of key members of the team. • The research into diabetes conducted in 1981 by George Alberti and his team at Newcastle, and collaborators elsewhere, was selected to provide the case study for this preliminary stage for several reasons. It was thought to have been important science and there was a belief that some of it had made a contribution to clinical practice. Chapter 2 : Bibliometric analysis • An original plan to look at publications produced over a three year period was changed to looking at the output of just one year, 1981, because in that year alone Alberti and colleagues published 29 articles. These form the 1st generation papers and the average number of citations they received is high. Identifying the citations given to these 29 papers resulted in 799 2nd generation papers and 12,891 3rd generation papers. The numbers involved meant that it was impractical to go beyond the 3rd generation. Within the high overall average, the variation in the number of citations per paper was iii considerable going from 76 to just one. Similarly, the half-lives of the 29 papers, ie the time taken for an article to receive 50% of its citations, ranged from two years to 11. • Articles can be given a Research Level (ie one of four levels from clinical observation to basic) based on the journals in which they appear. Such analysis demonstrates the breadth of Alberti’s work because the 29 articles are spread across all four Research Levels. Crucially, there was not a shift from basic to more clinical levels across the generations. The higher than average number of authors and addresses per paper is testimony to Alberti’s extensive collaborations. • The funding acknowledgements reveal the high proportion of papers supported, at least partially, by one funder: the British Diabetic Association, now Diabetes UK, which provided core support for Alberti’s Newcastle team. Chapter 3 : Categorisation of citations • Traditional citation analysis does not allow identification of the importance of the cited article to the citing article, and therefore limits the ability to use citation analysis to trace the impact of basic or early research on later research. We conducted a review of the literature of the meaning of citations. • From this review, a template was devised that allowed the location, nature and importance of citations to be recorded as well as the type of research (basic or clinical) described in the paper. This was used by six assessors on a sample of papers and inter-rater reliability was tested. Further work is required to refine the template and its definitions, and to improve its consistency in application. • Nevertheless, for initial analysis, it was applied to 623 out of the 799 2nd generation papers. A four point scale was used for the importance of the cited paper to the citing paper. In just 9% of cases was the cited 1st generation paper thought to be in one of the top two categories, ie of Considerable or Essential importance to the citing paper. • Statistical analysis revealed no relationship between the number of citations a paper received and the proportion of citations where the cited paper was classified as being of high (ie. Considerable or Essential) importance to the citing paper. Self-citations, however, were shown to be significantly more likely to be in this category. • The classification of the type of research (basic or clinical) by our analysis of each paper broadly agreed with the classification of the journals by Research Level. • The time constraints involved in applying the template, plus the lack of any overall pattern in terms of correlations between number and importance of citations, might point to the desirability of adopting a more selective approach, guided by qualitative analysis. In any selective approach, however, it is likely that self-citations should feature. iv Chapter 4 : Qualitative analysis • Given the number of co-authors, it seemed appropriate to send them a questionnaire rather than attempt to interview them. Therefore the interviewing was rather more concentrated than originally intended. Only one formal critical pathway was created, but it was undertaken by an expert in the field who worked with Alberti at Newcastle. • Some problems emerged in taking 1981 as the starting point for the study. Alberti identified 10 selected papers from the 1970s and 1980s that he felt had had most impact on clinical practice. These helped to give us both a better understanding of the payback from our 1st generation, or 1981, papers, and provided further material for analysis. • Attempting to describe the impact from the 1981 body of work, and from the 10 selected papers, underlines the complex reality of how science advances and influences clinical practice. If they make a contribution at all, most studies make a small, incremental one. • A few papers, however, have been shown to have a considerably greater impact. A possible key to the level of payback indicated is the enormous breadth of Alberti’s contacts, and fields and methods of working, to which various references were made. This is well illustrated in the account of how the idea for subcutaneous pumps came about. Similarly, the ability to produce the very important guidelines on treating diabetics during surgery, and diabetic coma, partly resulted from the application to clinical problems of the understandings gained from some of the basic/early clinical studies. It is significant that the key papers on these issues, all of which come from the list of 10 selected papers from the 1970s and 1980s, were having an impact on the 1981 work. • How far the collection of papers from 1981 have been drawn upon in similar ways is less clear. Nevertheless, papers on treating diabetics during open heart surgery, and on bolus delivery of insulin at meal times, were key parts of these wider streams, despite variable citation levels. Furthermore, various papers, including on acarbose, on portal infusion of insulin, and on semi-human insulin, were important steps in bodies of work in their respective areas. The complexity was illustrated by a paper that helped debunk the Chlorpropamide alcohol flushing hypothesis, and thus end a line of scientific enquiry: there was payback in stopping an incorrect line of inquiry, but nothing on which to build. • Each technique in the qualitative study produced information about the successful subsequent careers followed by many researchers trained through working with Alberti. • Historical perspectives, and insider expert opinions, were important in the qualitative analysis. Overall, the qualitative methods highlighted some limitations in the bibliometric approach but also showed how aspects of the citation analysis can complement the opinions expressed, for example about the importance of the breadth of Alberti’s work. v Chapter 5 : Lessons learnt and the way forward • Lessons learnt: a variety of methods can be used successfully to gather considerable data about the payback from a body of research undertaken 20 years ago. Traditional citation analysis alone, however, is not sufficient: the importance of the surgery papers despite their relatively low citation rates illustrates this. The qualitative methods are important and much of the analysis is strengthened by drawing on multiple approaches. Several problems remain, including: identifying a coherent starting point for the analysis; coping with the enormous number of papers involved in later generations; and refining the template for categorising citations and developing ways of fully utilising the results from applying it. • Preparing for the large-scale study: this preliminary study provides a basis on which to attempt to undertake the larger study we envisaged. Issues now being addressed include identification of the level of bibliometric/citation analysis necessary to complement any qualitative studies. To provide confidence in the findings from an eventual large-scale study, we will need to expand the focus. The study will need to cover at least four sets of case studies. Ideally, each set should focus on a number of research groups working in a country in the same field. We hope there will be sets of case studies in two or three fields and in at least two countries. The issues to be explored will include ones highlighted by this study such as breadth of work, level of collaboration, and the role of core funding. • Methods for the large-scale study: for each case study we now propose to employ two methodological elements based on the qualitative and quantitative techniques adopted in the preliminary study. They will work in parallel but the quantitative bibliometric analysis would be applied selectively to parts of ‘research lines’ (ie discrete themes of research) identified in the qualitative studies as being important in influencing clinical practice. • Presenting the findings: each research line could be written-up in a standardised document that would use the HERG payback model and categories to describe the impact of that research. We shall use the qualitative and quantitative data to compare and contrast the ‘payback’ of research lines by country and disease, and then identify common factors that correlate with the translation of basic or early clinical research. • Concluding comments: in the era of ‘evidence based policy’, research funders are looking for value for money in the research they support and for evidence on the effectiveness of different research strategies. In this study we have begun developing a methodology that will allow us to understand the complexity of research development over a series of generations. The utility of the policy research we propose here will only be realised when it is scaled up to cover a number of different fields in different settings.NHS Executive, London Regio

The diffusion of financial innovations: an examination of the adoption of small business credit scoring by large banking organizations

Financial innovation has been described as the “life blood of efficient and responsive capital markets.” Yet, there have been few quantitative investigations of financial innovation and the diffusion of these new technologies. Of the latter, there have been only three prior quantitative studies, and all three used the same data set on automated teller machines! ; This paper makes a significant contribution to the financial innovation literature by examining the diffusion of a recent important innovation of the 1990s: banks’ use of credit scoring for small business lending. The authors examine the responses of 95 large banking organizations to a survey that asked whether they had adopted credit scoring for small business lending as of June 1997 (56 had done so) and, if they had adopted it, when they had done so. The authors estimate hazard and tobit models to explain the diffusion pattern of small business credit scoring models. Explanatory variables include several market, firm, and managerial factors of the banking organizations under study. ; The hazard model indicates that larger banking organizations introduced innovation earlier, as did those located in the New York Federal Reserve district; both results are consistent with expectations. The tobit model confirms these results and also finds that organizations with fewer separately chartered banks but more branches introduced innovation earlier, which is consistent with theories stressing the importance of bank organizational form on lending style. Though the managerial variables signs are consistent with our expectations, none yields significant results.Credit scoring systems ; Financial modernization ; Commercial loans ; Bank loans
