We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data. Then, time-varying MPR are estimated from the cross-section of returns and betas. We prove the consistency and asymptotic normality of the estimators. We also perform Monte Carlo simulations for the conditional version of the three-factor model of Fama and French (1993) and show that nonparametrically estimated betas outperform rolling betas under different specifications of beta dynamics. Using return data on the 25 size and book-to-market sorted portfolios, we find that the nonparametric procedure produces a better fit of the three-factor model to the data, less biased estimates of MPR and lower pricing errors than the Fama–MacBeth procedure with betas estimated under several alternative parametric specifications.  相似文献

The total cost of employee absence for many employers is high, and the correlation between employee health and disability is clear. This article reviews several challenges employers face in managing employee health and absence in a well-integrated manner. Although such an undertaking is not easy, the additional cost national health care reform may bring makes the interrelationship between employer profitability and employee absence, health and disability more crucial than ever for employers to recognize and manage.  相似文献

We develop and present an ethics case dealing with an uncertain tax position. The case can be used to assess professional ethics as part of an assurance-of-learning (AOL) plan as well as a component of a course grade. We present data on student performance on this case over a 5-year period. Students consider existing ethical frameworks to identify and frame the potential ethical “dilemmas” they might face in addressing whether to countenance a client’s suggested treatment and disclosure of an uncertain tax position. In addition, students evaluate the AICPA guidance and U.S. Treasury standards on taking and reporting uncertain tax positions in the tax return and the FASB and PCAOB standards on reporting and auditing uncertain tax positions in the financial statements. The case allows faculty to assess students’ ability to frame potential ethical dilemmas when clients engage in aggressive tax behavior, to recognize with whom and with what professional reference documents they should consult when an uncertain tax position arises, and to choose among alternative actions when faced with client/preparer conflicts.  相似文献

There is a clear trend in corporate governance toward increased attention to the environmental and social impacts of business operations. Major consulting firms are advising Fortune 500 companies on how to become more environmentally sustainable, private equity and “impact” investors are measuring environmental, social, and governance (ESG) factors, and voluntary reporting and shareholder resolutions on issues of environmental sustainability are on the rise. While traditional corporate forms allow companies to embrace social and environmental responsibility with some measure of success, various real and perceived risks encourage directors to focus on short‐term profitability. Even if a company has a strong social mission at inception, founders often have difficulty “anchoring their mission” over time. And the lack of required disclosure of social and environmental performance makes it more difficult for investors to evaluate and compare companies. Many believe that the institutionalized mispricing of natural resources and the continued failure to price externalities, combined with the progressive nature of climate change, require the transformation of both business and law. This article discusses social and environmental sustainability within the traditional corporate form and then explores three emerging alternatives that are now being used by businesses in California: limited liability corporations (LLCs); benefit corporations (B corps); and flexible purpose corporations (FPCs). Of these three alternatives, FPCs—a corporate form that requires shareholders to agree on one or more social missions with management and the board—may be best suited to meet the needs of the many small private firms (as well as some large public companies) that, whether for purely economic or altruistic reasons, plan to integrate ESG into their operations.  相似文献

We examine investment in bank branches on the Indian subcontinent in 1939 and 1946. In 1947, the states of India and Pakistan were created from the erstwhile colony of British India. Partition was destabilizing to both economies. We use branch expansion as a proxy for entrepreneur's pre‐partition predictions of the future of these regions. Our results indicate there were no premonitions of economic dislocation. Banks tended to deepen their presence in regions which were already developed. But controlling for the level of 1931 development, branch placement was highest in exactly those regions, Bengal and the Punjab, which were to experience the greatest negative consequences from political division. After 1947, multiple banks failed; most failing banks were registered in the Punjab or Bengal region. In United India, businessmen saw as much promise in regions which were to become Pakistan as in regions which were to become India. After partition, the Pakistan regions were immediately more economically fragile. This event provides a general lesson. Economic integration had intensified over the years of British rule. The abrupt stop to integration harmed especially the smaller, less diversified region. Politicians should be wary of politically dividing regions which have evolved to function as integrated economic units.  相似文献

This study investigates the associations between self‐assessed adverse labor market events (experiencing problems with coworkers, employment changes, financial strain) and health. Longitudinal data are obtained from the National Epidemiological Survey of Alcohol and Related Conditions. Our findings suggest problems with coworkers, employment changes, and financial strain are associated, respectively, with a 3.1 percent (3.3 percent), 0.9 percent (0.2 percent), and 4.5 percent (5.1 percent) reduction in mental health among men (women). Associations are smaller in magnitude and less significant for physical health.  相似文献

We focus on the impact of three of Hofstede’s cultural dimensions, power distance, uncertainty avoidance, and individualism, on the results of analytical procedures conducted by entry-level auditors in Mexico and the U.S. Analytical procedures are ideal for this research as they require auditors to use professional judgment and appropriate levels of professional skepticism, abilities related to all three cultural characteristics. We find no other study investigating the impact of culture on the application of auditing procedures similar across the studied cultures.We find cultural characteristics do not affect the participants’ abilities to predict income statement balances, but they may influence the ability to predict changes in balance sheet accounts. We also find culture is associated with differences in risk assessments. Our results indicate that participants rarely differentiate accounts that change according to expectation from those that change contrary to expectation, but rather alter their risk assessments to match the direction of balances that increase or decrease.  相似文献

In the digital age, open innovation is increasingly organized around platform ecosystems. This paper investigates how firms can coordinate open innovation as a platform strategy for the development of complementary products by independent third parties. We draw on a qualitative case study of Philips Hue – a connected lighting platform for consumers with its variety of complementary products. We identify three increasingly complex ways in which independent complements connect to a focal platform. Our findings show that managing these connections requires a hybrid open innovation approach that combines arm’s length coordination, with a large number of complementors through open interfaces, and intensive bilateral collaboration, with a selected number of partners. Our findings demonstrate that complex interconnections across digital platforms and products lead to the management challenge of navigating an ‘ecology of platforms’, which warrants future research.  相似文献

The Health Insurance Portability and Accountability Act (HIPAA) is a standard for the healthcare industry mandating, in part, use of the EDI X12 protocol set for data exchanges among industry members. The motivation underlying this change was the view that lack of a standard format for healthcare data created significant inefficiencies, resulting in increased costs within the industry. With regulators’ supposition that the standard would improve data exchange performance, we set out to determine the actual performance implications of HIPAA.Using data on transactions occurring over 106 months from 1998 to 2004, we study the impact of the HIPAA standardization requirement on transaction performance in the form of transaction delivery time and transaction quality measured as percentage errors. Performance is expected to deteriorate immediately following HIPAA compliance, due to system disruption, before a longer-term trend toward improved performance. Transaction performance immediately following HIPAA compliance shows deterioration in transaction delivery time, as expected, but a surprising improvement in transaction quality. The longer-term trends associated with HIPAA compliance for both transaction quality and transaction delivery time show that both are trending toward improvement. However, when we compare performance three, six, and 12 months before and after HIPAA compliance, we find that neither delivery time nor quality has improved. The implications for practice and theory are discussed.  相似文献
