This article draws on investigations of worker response to two factory closures to develop recent discussions around mobilization theory. With many shared characteristics between the factories, both located in the garment manufacturing sector, and with similar workforces and union organization, certain key distinguishing features between the two provide insights into why worker protest became effectively mobilized and sustained in one case but failed to materialize in the other. The findings point to the value of assigning greater weight in studies of worker mobilization to the impact of prior existing social structures within a population, and the interaction between that population, its leaders and wider society.  相似文献

This paper studies the symmetric equilibria of a two-buyer, two-seller model of directed search in which sellers commit to information provision. More informed buyers have better differentiated private valuations and extract higher rents from trade. When sellers cannot commit to sale mechanisms, information provision is higher under competition than under monopoly. In contrast, when sellers commit to both information provision and sale mechanisms, I identify simple conditions under which sellers post auctions and provide full information in every equilibrium, ensuring that all equilibrium outcomes are constrained efficient. Sellers capture the efficiency gains from increased information and compete only over non-distortionary rents offered to buyers.  相似文献

Abstract

We estimate the increased mortality and term life insurance costs for women who have a family history of breast or ovarian cancer. Using data from the medical literature on age-specific and family history-specific incidence rates, we develop double-decrement models to evaluate the actuarial impact of breast cancer and ovarian cancer in the family. We also calculate the increased mortality and term insurance costs for women who test positive for the BRCA1 or BRCA2 gene mutation. We find that the type of affected relative and her age at onset of the disease are key underwriting factors. We find substantial mortality increases (up to 100%) for women with two relatives with cancer and women with a first-degree relative who developed cancer at an early age. Mortality increases for women with the BRCA gene mutation reach 150%. While some females with a family history of cancer can be accepted at standard rates, others may need to be quoted substandard rates, depending on the underwriting policy of the company. Females with the gene mutation can possibly be accepted at a rate that incorporates a severe mortality surcharge.  相似文献

We examine the relation between institutional investors and management discipline over the last several decades to better understand how CEO turnover has increased. Using a sample of forced and voluntary turnovers, we investigate the changing roles of activism and exit among institutional investors between 1982-1994 and 1995-2006. We find evidence of activist investors throughout the sample period and their impact is consistently significant in multivariate analysis. In contrast, voting with their feet has declined to the point where it no longer affects turnover outcomes. Nonetheless, activism is fairly uncommon and does not explain the higher turnover observed over time. Block holdings of known activists have increased and are linked to improving target firms. However, other blocks merely reflect the increasing size of institutional money managers. Going forward, the increasing size of institutional investors seems likely to inhibit voting with their feet while activism remains an important vehicle for change.  相似文献

Abstract

Little systematic research has investigated differences in expressed attitude as a function of the manner in which probability information is communicated to a decision maker. The purpose of this paper is to investigate differences in expressed attitude when insurance coverage is introduced in a known-risk situation (the probability of loss is known), an uncertain situation (there is no prior information on the probability of loss) or an ambiguous (the information provided is vague). The experiments reported in this paper have been developed and tested in the classroom with undergraduate students. Unlike the vast majority of previous work dealing with lotteries and laboratory gambles, this study examine the behavior of people when facing a purchase decision on a well-known consumer good, i.e. a bottle of wine. The comparative results provide some evidence on the risk-taking behavior of consumers for small losses. Within an insurance context, people prefer the more familiar option of a known-risk situation and contrary to expectations, the results do not provide support to ambiguity aversion but to ambiguity seeking.  相似文献

This article by the former chairman of the FASB and the founder and executive director of the new Sustainability Accounting Standards Board (SASB) presents the rationale for and mission of the SASB. As the authors point out, both the Securities and Exchange Commission, which was created in 1934, and the Financial Accounting Standards Board, set up in 1973, emerged during times of low investor confidence to restore trust in the capital markets. And the institutional changes brought about by the creation of both the SEC and the FASB succeeded in eliciting new information for investors and in raising the standards by which such information was reported. But as the authors go on to argue, we now live in a different world, one in which the management of environmental, social, and governance issues is increasingly viewed as critical to the long‐run value creation of companies. And because today's corporate reporting fails to account in a systematic way for material non‐financial issues, it's time once again for the capital markets to evolve. The SASB aims to meet this need by creating sustainability accounting standards for use by public companies in disclosing a minimum set of material sustainability impacts for companies in over 80 different industries. As part of a natural evolution in disclosure, the SASB aims to achieve the same goal the SEC and FASB started with: to protect investors and the public.  相似文献

Following up on the publication of the Walker Report ( 2009 ) in the United Kingdom, international organizations such as the Basel Committee ( 2010 ), the OECD ( 2010 ), and the European Union ( 2010 ) have proposed guidelines to improve bank corporate governance and, more specifically, risk governance. These international reports vary widely on what the prime objective of bank corporate governance should be, with one group recommending a shareholder‐based approach, and the other a stakeholder‐based one. Moreover, the focus of these reports is exclusively on risk avoidance, with little guidance as to how an acceptable level of risk should be defined. Drawing on insights from economics and finance, this paper is intended to contribute to the debate on bank corporate governance. Our four main conclusions are as follows. Firstly, the debate on bank governance should concern not only the boards but also the governance of banking supervision with clearly identified accountability principles. Secondly, since biases for short‐term profit maximization are numerous in banking, boards of banks should focus on long‐term value creation. Thirdly, board members and banking supervisors should pay special attention to cognitive biases in risk identification and measurement. Fourthly, a value‐based approach to risk taking must take into account the probability of stress scenarios and the associated costs of financial distress. Mitigation of these costs should be addressed explicitly in the design of bank strategy.  相似文献

Risk-neutral compatibility with option prices   总被引:1,自引:0,他引:1  
A common problem is to choose a “risk-neutral” measure in an incomplete market in asset pricing models. We show in this paper that in some circumstances it is possible to choose a unique “equivalent local martingale measure” by completing the market with option prices. We do this by modeling the behavior of the stock price X, together with the behavior of the option prices for a relevant family of options which are (or can theoretically be) effectively traded. In doing so, we need to ensure a kind of “compatibility” between X and the prices of our options, and this poses some significant mathematical difficulties.  相似文献
