HOW DO RATING AGENCIES’ DECISIONS IMPACT STOCK MARKETS? A META‐ANALYSIS

The purpose of this study is to examine how credit rating agencies’ decisions impact the stock market using a systematic and quantitative review of existing empirical studies. Specifically, we employ a meta‐regression analysis (MRA) to investigate the extent and nature of the effect of rating agencies’ decisions on the stock market. We survey 62 studies published between 1978 and 2015. Our first finding is that the cumulative average abnormal returns calculated from this empirical literature are affected by publication bias. After controlling for publication bias, the main findings of our meta‐analysis indicate that negative rating decisions cause statistically significant negative abnormal returns. This evidence suggests an informational effect. Our results also indicate that positive rating decisions do not have a significant effect. Finally, the MRA results reveal the importance of several factors related to primary study design, as well as to the nature of the data.     

Physicians and the risk of medical malpractice: The role of prior litigation in predicting the future

This article examines the role of a physician’s prior experience in medical malpractice litigation in the resolution of current malpractice claims. We first use probability theory to show that if physicians are heterogeneous in the quality of care they practice, then a record of malpractice liability makes it more likely that the physician provides care of relatively low quality, and that if a malpractice claim is filed, it is more likely that the physician was in fact negligent in this case, and that the claim will be paid. We then show that this last result, which is testable, holds up when we analyze the resolution of medical malpractice claims filed in Michigan over the period 1982 to 1989. We find that malpractice liability, whether from an out-of-court settlement or through verdict of a court or arbitration panel, is significantly more likely when the defendant has a poor prior litigation record. The defendant’s litigation record is also positively and significantly related to the amount of a settlement payment, but not to an award made through trial or arbitration.     

Central banks’ interest rate projections and forecast coordination

We apply a simple test to study the effect of the publication of central banks’ interest-rate projections on the coordination of private-sector interest-rate forecasts. Our results indicate that the publication of interest-rate projections does not lead private-sector forecasters to coordinate their forecasts. In fact, private-sector forecasters rather seem to anti-coordinate, that is, they scatter their forecasts around a consensus forecast or around a central bank's interest-rate projections.     

ALCOHOL MARKETING,ADOLESCENT DRINKING AND PUBLICATION BIAS IN LONGITUDINAL STUDIES: A CRITICAL SURVEY USING META‐ANALYSIS

Abstract This paper presents a meta‐analysis of prospective cohort (longitudinal) studies of alcohol marketing and adolescent drinking, which accounts for publication bias. The paper provides a summary of 12 primary studies of the marketing–drinking relationship. Each primary study surveyed a sample of youth to determine baseline drinking status and marketing exposure, and re‐surveyed the youth to determine subsequent drinking outcomes. Logistic analyses provide estimates of the odds ratio for effects of baseline marketing variables on adolescent drinking at follow‐up. Using meta‐regression analysis, two samples are examined in this paper: 23 effect‐size estimates for drinking onset (initiation); and 40 estimates for other drinking behaviours (frequency, amount, bingeing). Marketing variables include ads in mass media, promotion portrayals, brand recognition and subjective evaluations by survey respondents. Publication bias is assessed using funnel plots that account for ‘missing’ studies, bivariate regressions and multivariate meta‐regressions that account for primary study heterogeneity, heteroskedasticity, data dependencies, publication bias and truncated samples. The empirical results are consistent with publication bias, omitted variable bias in some studies, and lack of a genuine effect, especially for mass media. The paper also discusses ‘dissemination bias’ in the use of research results by primary investigators and health policy interest groups.     

Migrants Encounter Migrants in the City: the Changing Context of ‘Home’ for Second‐Generation Greek‐American Return Migrants

This article looks at the ‘return’ migration of second‐generation Greek Americans to their parents’ homeland, Greece. It is based on interviews with, and written accounts supplied by, 40 participants in the research, all now living in the Athens region. The article addresses two main sets of questions. First, why do they relocate to Greece, what are they looking for, and how do they cope with difficulties and disappointments? Second, and more specifically, how do they react to the fact that Greece is no longer a homogenous hellenistic society, but has become in recent years a de facto multicultural one due to the presence of hundreds of thousands of immigrant workers and their families? Three hypotheses are proposed for this inter‐migrant encounter: returnees, shocked by the ‘new immigration’, view it negatively as upsetting the ‘pure Greek’ homeland they had hoped to find; returnees are more sympathetic because of their own families’ history as immigrants in multicultural America; and returnees differentiate themselves as ‘good’ migrants from Greece’s immigrants who are constructed as ‘bad’ migrants. Evidence from the migrants’ testimonies is found to support all three hypotheses; however, there is more support for the second one. In addition, a fourth outcome was voiced: that of discrimination against Greek Americans who are made to feel, in certain circumstances, outsiders by the ‘true’ Greeks. Suggestions are made for further comparative research.     

Regulatory barriers to entry in the healthcare industry: the case of alternative medicine

To the extent that alternative medicine offers a substitute for mainstream physician services, physicians’ incomes are reduced by the incursion of alternative providers into the medical marketplace. State regulations restricting the practice of alternative medicine create rents for physicians whose incomes are protected from competition with alternative providers. Focusing on homeopathy as representative of an alternative therapeutic that potentially substitutes for conventional medicine, a cross-state empirical analysis reveals that mainstream physicians’ incomes are higher in states with more restrictive regulations governing the practice of homeopathy. This finding suggests that regulatory barriers to alternative medicine are motivated more by the interests of orthodox physicians in seeking protection from competition than by the interests of consumers in quality assurance.     

Waiting Lists and Patient Selection

We develop a positive model of waiting lists for public hospitals when physicians are able to divert patients from the public to the private sector. Public treatment is free but rationed, i.e., only cases meeting some medical criteria are admitted. Private treatment has no waiting time but entails payment of a fee. Physicians and patients take into account that each patient treated in the private practice reduces the waiting list for public treatment. We show that physicians do not necessarily end up treating the mildest cases from the waiting list. Our analysis is valid for a wide class of doctors' utility functions.     

Managed activism: two union organising campaigns in the not‐for‐profit sector

Two union recognition campaigns are contrasted: one focusing on developing workplace activism but with little sectoral focus (a ‘bottom‐up’ campaign), and the other with a sectoral strategy and less emphasis on workplace campaigning (a ‘top‐down’ campaign). The outcomes indicate the need for approaches, which allow both a strong workplace activism and a clear sectoral strategy as both the ‘top‐down’ and ‘bottom‐up’ strategies present difficulties. Although there are positive outcomes in both campaigns, the cases show that unions seeking to represent the interests of previously unorganised groups of workers need influence at both the sectoral and workplace levels if they are to demonstrate their effectiveness.     

SOCIO‐ECONOMIC STUDIES ON SUICIDE: A SURVEY

Abstract In this paper, we review economic theories and empirical studies on the socio‐economic aspects of suicide. Through our survey, we would like to emphasize the importance of studying suicide by employing a ‘rational’ approach that complements the medical perspective on suicide. We first introduce major economic theories of suicide and then present a summary of a variety of empirical studies from the socio‐economic perspective. To shed light on the mixed empirical evidence, we employ a meta‐regression method to investigate how the existing empirical results vary. We have identified a publication bias, not highlighted previously, in the existing literature with respect to several commonly employed socio‐economic factors. Several characteristics of existing studies have been identified as influencing the qualitative outcome. We then discuss the recent developments in economic studies on suicide, on the basis of the authors’ ongoing project on suicide. In the concluding section, we point out some issues for further studies.     

Following in Partners’ Footsteps: An Uncertainty‐Reduction Perspective on Firms’ Choice of New Markets

In this paper, we develop a new perspective on what determines firms’ choice of new markets for entry. First, drawing on the open‐system theoretical tradition and literature on inter‐organizational networks, we advance and empirically test the proposition that firms tend to enter new markets to which they are connected by partnership ties. We then show that this network influence is filtered through the structure of firms’ network connections to new markets and firms’ experience. Specifically, we find that multiplicity of connections to new markets, as well as the extensiveness of firms’ experience and its relevance to new markets weaken the effect of network ties on firms’ choice of new markets. The results of this study indicate that firms’ choice of new markets for entry is a nuanced process that is affected by the interplay of firms’ collaborative ties, the structure of their network, and firms’ internal capabilities. We test our hypotheses in the empirical context of the U.S. venture capital (VC) industry using panel data over a 23‐year period and find broad support for them.     

Rapports de propriété, ségrégation et pratiques de l'espace résidentiel

The aim of the authors is the theoretical reformulation of the question of segregation. In order to do this, they examine in turn psycho-sociological theories, morphological and semiological theories as well as theories of residential location. The authors show how all of these approaches can only define classificatory processes and propose an analysis beginning from those social relations which structure residential consumption; that is, relations of property in housing. Starting from a definition of segregation as a process of exclusive practices of residential space, the authors show how relations of residential property determine two types of segregation: one ‘by antagonism’, based on the valorization of property capital, and one ‘by incongruence’ based on conditions of real appropriation of housing.     

‘Sameness’ and ‘Difference’ Revisited: Which Way Forward For Equal Opportunity Initiatives?

Recent interest in ‘managing diversity’ has reopened debates about forms of equality in the workplace. Approaches to equality developed in the 1970s and 1980s have been characterized as an attempt to ensure that if individuals bring the same abilities to work, or perform in the same way, they should receive the same access to jobs and employment benefits, regardless of social group membership. Managing diversity appears to be about a more positive valuing of difference. Benefits are seen to derive from different perspectives and approaches and these should be nurtured and rewarded rather than suppressed. Feminists have long argued about the extent to which women are the same as, or different from, men, and about the political consequences of adopting these positions. Recent theoretical developments have led to some novel solutions to this dilemma. These include asserting claims to both ‘sameness’ and ‘difference’, the deconstruction of ‘difference’, and the reconstruction of ‘sameness’ on women's terms. This paper explores approaches to equal opportunities through both established and novel theoretical perspectives. It argues that existing practice cannot be fitted neatly into the conventional distinctions between ‘sameness’ and ‘difference’, and explores the potential characteristics and strengths and weaknesses of equality initiatives based on the new theoretical perspectives.     

The ‘New Competition’ and Working Time

Jill Rubery, who is Senior Lecturer at the Manchester School of Management, and Sara Horrell, Lecturer in the Faculty of Economics, University of Cambridge, draw on a study for the Equal Opportunities Commission to discuss the significance of the competitive conditions said to lie behind changes in working time. They argue that the existing approaches to understanding these changes – they are ‘determined’ by the ‘market/technology’ or relate to a redefinition of power relations within the workplace – are both inadequate. What is required, they suggest, is a more complex analysis of competition which takes into account both the factors that shape market conditions and the factors inside the organisation that influence responses to them.     

Factor MIDAS for Nowcasting and Forecasting with Ragged‐Edge Data: A Model Comparison for German GDP*

In this article, we merge two strands from the recent econometric literature. First, factor models based on large sets of macroeconomic variables for forecasting, which have generally proven useful for forecasting. However, there is some disagreement in the literature as to the appropriate method. Second, forecast methods based on mixed‐frequency data sampling (MIDAS). This regression technique can take into account unbalanced datasets that emerge from publication lags of high‐ and low‐frequency indicators, a problem practitioner have to cope with in real time. In this article, we introduce Factor MIDAS, an approach for nowcasting and forecasting low‐frequency variables like gross domestic product (GDP) exploiting information in a large set of higher‐frequency indicators. We consider three alternative MIDAS approaches (basic, smoothed and unrestricted) that provide harmonized projection methods that allow for a comparison of the alternative factor estimation methods with respect to nowcasting and forecasting. Common to all the factor estimation methods employed here is that they can handle unbalanced datasets, as typically faced in real‐time forecast applications owing to publication lags. In particular, we focus on variants of static and dynamic principal components as well as Kalman filter estimates in state‐space factor models. As an empirical illustration of the technique, we use a large monthly dataset of the German economy to nowcast and forecast quarterly GDP growth. We find that the factor estimation methods do not differ substantially, whereas the most parsimonious MIDAS projection performs best overall. Finally, quarterly models are in general outperformed by the Factor MIDAS models, which confirms the usefulness of the mixed‐frequency techniques that can exploit timely information from business cycle indicators.     

‘Thinking Before Acting’ or ‘Acting Before Thinking’: Antecedents of Individual Action Propensity in Work Situations

We introduce the concept of ‘individual action propensity’ to examine the approach of individuals towards solving situations for which they lack knowledge and/or experience about what to do. We focus on a naturally contrasting pair of responses: ‘thinking before acting’ or ‘acting before thinking’, and associate low action propensity with thinking one's way into understanding how to act, and high action propensity with acting one's way into understanding such situations. We build on regulatory mode theory – with its dimensions of locomotion and assessment and the trade‐off between speed and accuracy – to examine individual characteristics as predictors of individual action propensity. We find that individual action propensity is associated with being a woman, having fewer years of formal education, not relying on help‐seeking behaviours, and having a positive attitude towards spontaneity. Our findings shed light on why individuals take action, or not, and provide implications for research on organizational action propensity.     

A perspective on pharmacy training and practice.

The role of the pharmacist is expanding. Pharmacists are being employed now as drug information sources. Physicians are using pharmacists to aid in the proper dosing of aminoglycosides and chemotherapy agents. Many physicians inquire about the proper method to prescribe certain drugs. Nurses and other health personnel rely on the pharmacist to help in special areas of treatment, such as code blue services or patient counseling. As advances in medical treatments are made, each health professional must accept his or her increased responsibility to work with other health professionals to offer the most current and precise medical therapy available. I believe the profession of pharmacy will accept this increased responsibility to serve those in need.     

Making the ‘Invisible’ Visible: Redevelopment‐induced Displacement of Migrants in Shenzhen,China

Gentrification in China is intertwined with urban redevelopment, which causes the large‐scale displacement of rural–urban migrants from ‘villages in the city’ (ViCs). Because of the informality of ViCs, migrant renters have very insecure tenancy and during redevelopment they are treated as a negligible (‘invisible’) social group. As they are very difficult to locate after displacement, they are also literally invisible to researchers. To make the invisible visible, this study traced a sample of displaced migrants from Huangbeiling village in Shenzhen. The focus was on the displacement process and on identifying the consequences for the displaced. We found various forms of displacement during the redevelopment process. Nearby ViCs were prioritized by displaced migrants to minimize as much utility loss as possible. However, they generally suffer from decreased proximity, increased living costs, and the loss of social networks and job opportunities. Remarkably, some choose to return to the gentrifying village, enduring displacement in situ caused by increasing rents, drastic physical neighbourhood changes and declining liveability, in exchange for retaining their original social and economic networks. Large‐scale urban redevelopment is causing the rapid shrinkage of informal housing. Recognizing and addressing the housing needs of this impoverished social group is a matter of urgency.     

The ‘new’ donor: creation or evolution?

The unusual mass of financial capital produced in the late 20th century, complemented by the creative thinking of innovative philanthropists, engendered new ideas for philanthropy. An entrepreneurial focus, greater emphasis on partnerships among business, government and nonprofit sectors, and new wealth as well as new social innovation dramatically affected the philanthropic scene — and therefore nonprofit organisations and fundraising. A publication extolling venture philanthropy stated, ‘Philanthropy may be on the cusp of the greatest revolution in the nonprofit sector since Congress granted tax‐exempt status in 1954’.[Morino Institute (2001) ‘2001 Venture Philanthropy: The Changing Landscape’, prepared for the Morino Institute and Venture Philanthropy Partners, Inc., by Community Wealth Ventures, Inc.] This paper defines the terminology that identifies the new donor, describes new roles and practices in philanthropy, and looks at how the new donor fits into a comprehensive fundraising programme. New approaches to philanthropy versus traditional philanthropy are considered, including whether or not these approaches are actually new or represent an evolution in giving.

Non‐Economic Factors in Economic Geography and in ‘New Regionalism’: A Sympathetic Critique

In the current debate on local and regional development and after several ‘turns’, dominant critical models have found some security in institutional, cultural and evolutionary approaches. Interest today centres on success and competitiveness and how they are reproduced in a few paradigmatic regions. A distinctive feature of these regions and places is the embeddedness of certain non‐economic factors such as social capital, trust and reciprocity based on familiarity, face‐to‐face exchange, cooperation, embedded routines, habits and norms, local conventions of communication and interaction, all of which contribute to a region’s particular success. Although these approaches may not deny the forces of the capitalist space economy, they do not explicitly acknowledge them or take them on board and so they tend to discuss non‐economic factors and institutions as autonomous forces shaping development. This essay provides a critique of these concepts based on their (1) inadequate theorization, (2) depoliticized view of politics and de‐economized use of economics and (3) reduction of space to territory. The essay concludes that we need a far more penetrating renewal of radical critique of the current space economy of capitalism. Old concepts such as uneven development, the social and spatial division of labour, the geographical transfer of value, accumulation and imperialism must be combined with cultural and institutional issues, with those non‐economic factors mentioned above.
