In tests of the relative performance evaluation (RPE) hypothesis, empiricists rarely aggregate peer performance in the same way as a firm’s board of directors. Framed as a standard errors-in-variables problem, a commonly held view is that such aggregation errors attenuate the regression coefficient on systematic firm performance towards zero, which creates a bias in favor of the strong-form RPE hypothesis. In contrast, we analytically demonstrate that aggregation differences generate more complicated summarization errors, which create a bias against finding support for strong-form RPE (potentially inducing a Type-II error). Using simulation methods, we demonstrate the sensitivity of empirical inferences to the bias by showing how an empiricist can conclude erroneously that boards, on average, do not apply RPE, simply by selecting more, fewer, or different peers than the board does. We also show that when the board does not apply RPE, empiricists will not find support for RPE (that is, precluding a Type-I error).  相似文献

This study examines whether sanctions imposed by the China Securities Regulatory Commission (CSRC) against individual auditors result in greater auditor conservatism. Using a difference-in-differences research design, we find that clients of sanctioned individual auditors have lower discretionary accruals in the post-sanction period than in the pre-sanction period when compared to a matched control group of clients audited by individual auditors who were not sanctioned. Our findings suggest that sanctions imposed by the CSRC on individual auditors can lead to improvements in audit quality by increasing the conservatism of the sanctioned auditors. That is, individual auditors are more likely to resist their clients’ income-increasing accounting manipulations after being sanctioned by the CSRC.  相似文献

Growing concern that a dollar peg exposes East Asian economies to fluctuations in the dollar–yen exchange rate has stimulated research on currency basket regimes as alternatives for these economies. However, existing studies have mostly ignored an important characteristic of East Asia, i.e., most of its international trade is invoiced in the U.S. dollars. This paper investigates how the preponderance of dollar invoicing affects optimal currency basket regimes for East Asian economies. I develop a three-country center-periphery sticky-price dynamic stochastic general equilibrium model for the analysis. The model is solved numerically by taking second-order approximations to the policy functions with the expected lifetime utility of households chosen as the welfare criterion. Contrary to the conjecture of existing literature, I show that predominance of dollar invoicing implies that the dollar should receive a smaller weight than suggested by bilateral trade shares between emerging markets in East Asia and the United States. The results hinge on the interaction of different degrees of pass-through implied by the choice of invoice currency and endogenous responses of monetary policies in the center countries.  相似文献

Background: Sacubitril/valsartan reduces cardiovascular death and hospitalizations for heart failure (HF). However, decision-makers need to determine whether its benefits are worth the additional costs, given the low-cost generic status of traditional standard of care.

Aims: To evaluate the cost-effectiveness of sacubitril/valsartan compared to enalapril in patients with HF and reduced ejection fraction, from the Singapore healthcare payer perspective.

Methods: A Markov model was developed to project clinical and economic outcomes of sacubitril/valsartan vs enalapril for 66-year-old patients with HF over 10 years. Key health states included New York Heart Association classes I–IV and deaths; patients in each state incurred a monthly risk of hospitalization for HF and cardiovascular death. Sacubitril/valsartan benefits were modeled by applying the hazard ratios (HRs) in PARADIGM-HF trial to baseline probabilities. Primary model outcomes were total and incremental costs and quality-adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER) for sacubitril/valsartan relative to enalapril

Results: Compared to enalapril, sacubitril/valsartan was associated with an ICER of SGD 74,592 (USD 55,198) per QALY gained. A major driver of cost-effectiveness was the cardiovascular mortality benefit of sacubitril/valsartan. The uncertainty of this treatment benefit in the Asian sub-group was tested in sensitivity analyses using a HR of 1 as an upper limit, where the ICERs ranged from SGD 41,019 (USD 30,354) to SGD 1,447,103 (USD 1,070,856) per QALY gained. Probabilistic sensitivity analyses showed the probability of sacubitril/valsartan being cost-effective was below 1%, 12%, and 71% at SGD 20,000, SGD 50,000, and SGD 100,000 per QALY gained, respectively.

Conclusions: At the current daily price sacubitril/valsartan may not represent good value for limited healthcare dollars compared to enalapril in reducing cardiovascular morbidity and mortality in HF in the Singapore healthcare setting. This study highlights the cost-benefit trade-off that healthcare professionals and patients face when considering therapy.  相似文献

This article explores the relationship between culture and cyberloafing. A survey measuring individuals’ propensity to engage in cyberloafing in the workplace was conducted with people from 17 countries representing a wide range of cultures. Tests were performed to explore relationships between participants’ propensity to cyberloaf and the cultural dimension ratings for their individual countries of origin. The results show that some types of cyberloafing activity relate significantly with culture. This has potential implications for multinational organizations. Employees from different cultures may have different workplace tendencies.  相似文献

Using trade and quote data from the NYSE, we examine the relation between dealer attention, dealer revenue, and the probability of informed trade. We find that dealer revenue net of losses to better-informed traders in NYSE stocks is positively related to the speed at which quotes adjust to full information levels. The speed of quote adjustment is faster for stocks with greater dealer attention, as measured by a stock’s relative prominence at its post and panel location on the NYSE floor. The level of dealer attention in turn is positively related to a stock’s probability of information-based trading. The results are consistent with a theoretical model we derive in which dealers trade multiple securities and must optimally allocate their limited attention to monitoring order flow to minimize losses to better-informed traders.  相似文献

Although new investment can be viewed as a decision to pursue projects from a wide number of growth opportunities with easily discernible (and presumably preferable) risk profiles, downsizing (e.g., through layoffs, plant closings, asset divestitures, etc.) is a dichotomous choice to either abandon or continue an existing project where the relative risk between these options is not clear. Our evidence suggests that vega in the pre-downsizing period is associated with risky investment that necessitates future downsizing. We further find that contemporaneous vega is associated with a greater likelihood of downsizing. On the other hand, our evidence suggests that delta is a significant impediment to downsizing. We examine the influence of behavioral factors in the decision-making process and find downsizing decisions are discouraged by managerial overconfidence but encouraged by managers’ aversion to ambiguity. Finally, we investigate whether equity incentives and behavioral factors lead to better downsizing decisions. We find that downsizing firms with high ambiguity perform better after downsizing relative to their matched pair with lower ambiguity.  相似文献

In a recent article, Jacobson (2015) provides an invaluable economics job market guide for economics Ph.D. candidates from “non‐top‐tier” programs in the United States. Her treatment is detailed and, to a large extent, thorough. However, Jacobson fails to discuss the development of effective lead teaching experience in graduate school as a (potentially central) aspect of job market preparation. In the present comment, we develop and summarize a job posting and placement data set that focuses on Ph.D. candidates from non‐top‐tier programs. The data strongly suggests that the development of lead teaching experience in graduate school, rather than an optional line on one's vita, is an often pivotal element of realized job placement for Ph.D. candidates of non‐top‐tier programs. These findings corroborate with List's (2000) finding that, “a candidate's teaching portfolio was highly influential in the academic market” (p. 197). We also discuss the acquisition of lead teaching experience and benefits of early teaching experience that may extend beyond first job placement.  相似文献
