Replacement brood cows are among the most significant investments for cow-calf operations, thus crucial to profitability. Many cow-calf producers find it cost effective to purchase replacements from a reliable replacement heifer seller, though by doing so they increase risk of reproductive inefficiency due to unknown characteristics of the heifers. When important information about a product is missing to buyers, a seller can build a reputation over time that acts as signal for quality. Previous work has explored reputation effects in feeder cattle markets, but to our knowledge we are the first to explore reputation effects in bred replacement cattle markets. Using data from an annual replacement heifer sale, we analyze the values of heifer characteristics and test for premiums from reputation development. After controlling for reproductive practices, breed, and other characteristics, we find reputation does not play the role that Shapiro theorized. In this sale, the lot order is strategically chosen and may indicate bred heifer quality to buyers, replacing the need for reputation as a signal. This study highlights the importance of quality signals and regional preferences in bred replacement cattle marketing and lays the empirical groundwork for future studies to test Shapiro's theory.  相似文献

PLANNING AND TACTICAL FACTORS IN THE PROJECT IMPLEMENTATION PROCESS   总被引:1,自引:0,他引:1  
It has been a well-recognized axiom in project management research that the project implementation process can be greatly facilitated by addressing a variety of project critical success factors. It is argued here that critical factors often fall into two distinct sub-groups: those related to initial project planning and those concerned with subsequent tactical operationalization. A field study was conducted to explore changes in the perceived importance of project planning and tactical factors across four stages in the project life cycle. The sample consisted of 408 managers currently involved in projects. It was found that the relative importance of planning and tactical factors varies across the project life cycle. Further, the perceived importance of these factors is contingent upon the type of success measure employed. When an efficiency success measure is used, planning factors are initially perceived to be of high importance but are overtaken by tactical issues as the project progresses through its life cycle. When ‘external’ success measures (perceived value of the project and client satisfaction) are employed, project planning factors dominate tactics throughout the project's life cycle. Finally, implications for managers are developed and directions for future research are discussed.  相似文献

How are unemployment and output affected if wages are set on the sector level rather than firm level? We take a new look at this question, allowing for heterogeneous firms and rent‐sharing motives. Without these motives, employment and output are lower under sector‐level wage‐setting due to higher wage markups. With rent‐sharing motives, however, firm selection is higher under sector‐level wage‐setting, which tends to increase employment and output, thus counteracting the markup effect. Simulations show that the firm‐selection effect decreases the difference between the two unionization structures substantially but it does not change the signs of the effects on output and employment.  相似文献

Managerial capacity builds over the years and the accumulated knowledge/practice affect the outcome of the period that follows, with long‐run/permanent effects on inefficiency. Therefore, predictions of the influence of managerial capacity on the time‐varying inefficiency, regularly estimated as overall efficiency, may be biased. This study analyzed the influence of farm management practices on both the persistent and residual efficiency, and evaluated how conclusions drawn about the effect of management practices are assessed if overall efficiency, instead of permanent and residual efficiency, is evaluated. Farm‐accounting data of Swedish pig producers and information from a survey related to managerial practices were used. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

According to the last report “Women FTSE 2009” developed by Cranfield School of Management and the IE Business School and sponsored by Pricewaterhouse-Coopers, Sainsbury, Enlivens, HSBC and Pearson, the number of European companies with women in positions of executive direction has been reduced from 16 to 15 and the number of women in the board meetings from 39 to 37 has fallen. Moreover, there has been a decrease in the number of total of businesses with women in their counsels, since 1 of each 4 businesses has an exclusively male counsel. The study, reveals a pessimistic panorama for women from the analysis of the number of guidelines that work in the companies that belong to FTSE 100, the British index that includes the 100 main values of the London stock market. The study also reflects a descent in the number of women that occupy key positions in the businesses of the FTSE 100. In the year 2008 there were only 5 women CEOs and 3 regional executive directors. In the 2009 only there were 4 CEOs. The purpose of this article is to see if the origin of this situation is a direct consequence of businesswomen confronting more difficulties than the businessmen upon putting in common its professional and personal life or if by contrast this corresponds to an stereotyped perception of gender inequality. With this end we conducted a study using a sample of businesswomen and men with experience analyzing its motivations to create business, difficulties that they find, and the solutions to improve the conciliation of its professional and personal lives. The results show that there are no significant gender differences in the motivations, regardless of who the head of the family is (bearing main responsibility for the house and children). On the other hand, we show that businesswomen diverge from businessmen in the perception of motivations and challenges they have. Indeed, businessmen agree with businesswomen in the motivations and difficulties that these have, and consider that they give to them more importance than women themselves.  相似文献

We analyze normalized productivity differences for 15 developing Latin American countries and four firm types: National Domestic, National Exporter, Foreign Domestic, and Foreign Exporter. There are no productivity thresholds for viability, export activity, or multinational activity, but we do find a clear size productivity premium and development productivity premium in the manufacturing sectors. We also find a clear foreign-ownership productivity premium, both for domestic firms and for exporting firms and both for manufacturing sectors and services sectors. In contrast, we only find an export productivity premium for national firms in the manufacturing sectors.  相似文献

This paper examines the role of media coverage and investor attention on the outcomes of seasoned equity offerings (SEOs). I use an archive of Thomson Reuters news articles to proxy for firm visibility and investor attention. I find that the volumes of news articles prior to the offerings are positively associated with the offer price discounts of SEOs. Furthermore, the volumes of news articles are negatively associated with the cumulative abnormal returns three days around the SEOs. I conclude that the costs of equity increase with media coverage prior to SEOs. Overall, the evidence is consistent with the hypothesis that media coverage affects investors' information processing in SEOs. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.  相似文献
