Although sell-side analysts privately forecast revenues and expenses when producing earnings forecasts, not all analysts choose to provide I/B/E/S with earnings forecasts disaggregated into revenues and expenses. We investigate the role of reputation in explaining this decision. We find that analysts without established reputations are more likely than reputable analysts to issue disaggregated earnings forecasts to I/B/E/S, consistent with I/B/E/S exposure benefits accruing to analysts seeking to establish a reputation. Among less reputable analysts, those with high ability are more likely to disaggregate, consistent with this group reaping greater benefits from the exposure I/B/E/S provides. Additional tests support our primary hypotheses. Among less reputable analysts, those who disaggregate are more (less) likely to be promoted (demoted or terminated). The stock market responds similarly, with more weight assigned to earnings forecast revisions provided by analysts who disaggregate their earnings forecasts.  相似文献

We examine how the different mix of informed and liquidity trading in the market for ETFs affects the nature of inter-market competition. We find that both the characteristics of the securities and the structures of the competing markets jointly determine the nature of inter-market competition. Given the superior execution quality on the ECNs and the low adverse selection costs in the ETF market, anonymous market such as the ECNs, attract both liquidity and informed traders. We also find that markets compete in a subset of ETFs. In addition, we find that quotebased competition is prevalent in the market for ETFs.  相似文献

The critical state of the hospital industry, as previously described, generates a difficult decision environment for the materiel manager and those in the purchasing function. The unique life- and death circumstances of hospitals impose a further onus on those who manage them. In the name of saving lives, they can find a convenient excuse to disregard all moral principles, forgetting the Socratic dictum \"it is not enough that one lives, but that one lives well.\" Without the moral \"right stuff,\" they can easily give in to the seductions of momentary gains and glory through ethical short-cuts. There is wisdom and consolation in the words that \"nice guys may appear to finish last, but usually they're running in a different race.\" Studies have established a direct relationship between corporate excellence and ethical values. The reality of competition in the hospital industry dictates that the integration of ethics into the life of the organization should happen by design and not by accident. This is what is meant by strategy. If hospitals would strive for excellence to survive and grow, they should have a strategy with a mission statement that also embodies its moral values and moral agenda. Such an approach does not guarantee that an organization will become immune to moral contamination, but it does provide an antidote.  相似文献

Resource economists are often asked to value a proposed change at one, and only one, recreational site; the model we develop and estimate is applicable for those cases. The application is valuing the elimination of fish consumption advisories on a large bay on Lake Michigan. The model is minimal but complete: complete in that the choice set is not restricted, minimal in that only two conditional indirect utility functions are estimated. It is utility-theoretic and one does not have to collect characteristic data on all of the other fishing sites in the region. Data include the number of trips each individual currently takes to Green Bay, answers to "would you prefer to fish Green Bay under conditions A or B?" and how often each angler says they would fish Green Bay under different sets of conditions.  相似文献

This article examines how companies can harness virtual reality (VR) technology to help make themselves more innovative. VR has some unique characteristics which, taken together, can help companies to develop three features common to many innovative organisations: a capacity to experiment in depth; involvement of all in the innovation process; and an ability to capture ideas generated in the innovation process. However, some obstacles need to be overcome before VR fulfils this potential.  相似文献

The outcome of the Common Agricultural Policy, with its “managed” market for farm products, has been high prices and surplus production, the disposal of which incurs a heavy expenditure on market support. At the same time, structural changes have been relatively insignifcant in the absence of a coherent E.E.C. programme, and, farms remain predominantly small and uneconomic. Financial and social pressures have compelled the Comission of the E.E.C. to admit that the Common Agricultural Policy needs to be radically re-appraised. In December 1968, far-reaching proposals, the so-called “Mansholt Plan”, were put forward by the Comission. This paper outlines and compares the structural policies of E.E.C. member States, and considers their impact upon the structure of farming. An assessment is also made of the measures included in the Mansholt Plan and in subsequent Community proposals designed to raise farmers' living standards and to reduce the cost of the Common Agricultural Policy.  相似文献

We investigate the impact of a potential new sports venue on residential property values, focusing on the National Football League's Dallas Cowboys' search for a new host city in the Dallas-Fort Worth area. We find that residential property values in the city of Dallas increased following the announcement of a possible new stadium in the city. At the same time, property values fell throughout the rest of Dallas County, which would have paid for the proposed stadium. These patterns reversed when the Dallas stadium proposal was abandoned. Subsequently, a series of announcements regarding a new publicly subsidized stadium in nearby Arlington, Texas, reduced residential property values in Arlington. In aggregate, average property values declined approximately 1.5% relative to the surrounding area before stadium construction commenced. This decline was almost equal to the anticipated household sales tax burden, suggesting that the average expected amenity effect of hosting the Cowboys in Arlington was not significantly different from zero.

This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students.  相似文献
