A statistically optimal inference about agents' ex ante price expectations within the US broiler market is derived using futures prices of related commodities along with a quasi‐rational forecasting regression equation. The modelling approach, which builds on a Hamilton‐type framework, includes endogenous production and allows expected cash price to be decomposed into anticipated and unanticipated components. We therefore infer the relative importance of various informational sources in expectation formation. Results show that, in addition to the quasi‐rational forecast, the true supply shock, future prices, and ex post commodity price forecast errors have, at times, been influential in broiler producers' price expectations.

We evaluate the appropriateness of regulation within the Canadian cable television industry by applying both parametric and non-parametric approachesto measure scale efficiency. Although we begin with a sample offering adequatedegrees of freedom for parametric estimation, important policy issues lead us toconsider further estimation over sub-samples. Since some of these sub-samplesare small enough that parametric models cannot guarantee reliable estimates, weobtain production characteristics non-parametrically through data envelopmentanalysis. The nonparametric results for scale efficiency support the parametricresults. We find evidence against a natural monopoly argument that might havejustified continuation of the mandated monopolization of Canadian cable televisionservice. By the end of the sample period, there were no longer substantial economiesof scale in most relevant markets. 相似文献

The pensions pillarisation agenda envisages a reduction in the role of social insurance while simultaneously advocating the parallel expansion of fully funded private sector, occupational and personal retirement contingencies. Widespread perception of looming state failure in the field of pensions delivery highlights the inherent limitations of current pension delivery arrangements. However, moves to de-emphasise the provision afforded by, predominantly, monopillar state-mandated pension systems by expanding private privision represent short-term palliative responses to deep rooted structural and demographic problems. Multipillar systems appear no more capable of guaranteeing system funding in the face of demographic ageing and structural unemployment than existing monopillar systems. Moreover, a diminished role for social insurance will leave the low paid and unemployed significantly more vulnerable in old age. Consequently, this paper argues for a pension reform agenda which, in terms of levels of income substitution, will secure an adequate social insurance element into the future. 相似文献

Previous research on unit management buyouts, UMBs, has shown that selling firms benefit from the selloff transaction. The current research demonstrates that when the selling firm has either poor liquidity or poor earnings, selling firm shareholders do not benefit as much. We hypothesize that the unit managers have knowledge about the selling firm's difficulties so they do not pay as large a premium for the assets. Since the unit managers technically are employed by the selling firm shareholders, their bargaining to achieve a better price is an agency cost. Finally, selloff frequency does not affect seller abnormal returns. 相似文献

This article examines the effects of high school athletic participation on the future wages of black males. Our evidence suggests that former black male athletes receive significantly greater wages than their otherwise comparable counterparts. Data from the National Longitudinal Survey of Youth was used for the analysis and allows for comparisons of the athlete premium to be made at different points in time. Both the human capital and signaling models are discussed. There appears to be a once and for all enhancement to human capital that accrues to black males who participated in high school athletics. The article adds to the literature on determinants of black male wages and on the earnings effects of athletic participation. 相似文献

One can determine the nature of something by asking what it is for. For example one understands what a chair is when one understands it is for sitting on. This involves understanding its purpose. One type of corporation is the for-profit-corporation. This seems to indicate that this type of corporation, the business corporation, has as its purpose to make a profit. Is that as obvious as it first appears? The favorite way for philosophers to arrive at the "purpose" of anything is to ask the question "Why?" But there are at least two answers to the question "Why"? when addressed to a social practice such as business. One might be asking for a psychological account (explanation) of "Why" a person does business, and this is primarily answered by discovering the motives behind business activity; or one might be asking for a justificatory reason (justification) for the practice – what purpose legitimates business as a human activity. These two answers are often conflated and thus the purpose of business is often considered to be answered by giving the psychological account of the self-interested profit-making motive. This paper will attempt to highlight the importance of making the distinction between motive and purpose clearly, show what confusions arise when the distinction is ignored, and hint at some of the structural philosophical reasons why the distinction got blurred in the first place. 相似文献

The relationship between the number of employees in a firm, their rank, and the level of professionalism among firm members is evaluated in 19 accounting firms, involving 325 accountants engaged in public practice. Professionalism is measured using five individual traits plus a composite. Results indicate that one trait (i.e. a belief that the profession provides a service to society) and the composite were inversely related to firm size. Rank or position in the firm hierarchy demonstrated an even stronger, independent effect on three professionalism traits and the composite, with higher member rank associated with higher levels of professionalism. Issues related to the future study of professionalism among accountants are discussed. 相似文献
