Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information. 相似文献

In recent decades the interest of academic researchers in the practical aspects of management accounting has waned. This editorial explores some of the reasons of this development. Over the past few decades we have witnessed the establishment of management accounting in academia as a social science. This has increased the credibility of the accounting academics. However, it has also meant that academic researchers have neglected the technical core of their discipline and its problems and issues which have a direct practical relevance. It is concluded that there is a need for academic researchers to have a stronger focus on the technical core of the subject and to harness the findings of empirical research so that they can be used to develop and support practice. 相似文献

Caplan holds that governments are Leviathans, seeking to extend their power by increasing government expenditures beyond the level preferred by voters. We extend Caplan's model by examining the real (percentage) growth rates of government. We also examine whether government size increases at an increasing rate as the minority party weakens. We find evidence that supports and fails to support the original Leviathan hypothesis. We also fail to support our extensions of Caplan's hypothesis. Furthermore, our significant and contrary results have intuitively appealing interpretations. From these results, we conclude that the impact of political party power on government spending is ambiguous. 相似文献

Successful regional products, such as Florida oranges, Idaho potatoes and Parma ham, often have to compete against products passing themselves off as the authentic product using the exact same name. This unfair competition misleads consumers, discourages small‐ and medium‐sized enterprises (SMEs) from marketing products based on their region of origin, and may end up hurting rural economies. To protect consumers, and support SMEs and rural economies, many countries around the world have introduced regulations enabling SMEs to legally protect the names of their regional products. The success of these regulations largely depends on consumers’ appreciation of regional certification labels that inform consumers that the name of the regional product is protected and that it denotes the authentic product. To gain an understanding about consumers’ appreciation of regional certification labels, this paper investigates consumers’ image of these labels and proposes a model that relates this image to consumers’ willingness to buy and pay for protected regional products. The model is tested based on Regulation No. 2081/92 that was introduced by the EEC allowing European SMEs to protect their regional products and market their products with a protected‐designation‐of‐origin (PDO) label. Structural equation modelling results suggest that consumers’ image of regional certification labels consists of a quality warranty dimension and an economic support dimension, which positively relate to consumers’ willingness to buy and pay for the protected regional product. Protecting regional products and marketing them with regional certification labels may be beneficial for SMEs producing and marketing regional products. Policy and managerial implications are discussed. 相似文献

We develop and test an integrative model that examines the fit between compensation schemes, executives' characteristics, and situational factors. We propose that a fit among all three factors is crucial to motivate desirable managerial behaviors. Using a specially designed management simulation, our study demonstrates that the effectiveness of incentive compensation to motivate managerial behaviors depends on executives' core self-evaluation and firm performance. Our results show that, relative to fixed salary compensation, executives with higher core self-evaluation respond to incentive compensation with greater perseverance, competitive strategy focus, ethical behavior, and strategic risk taking during organizational decline. However, these interaction effects are not present during organizational growth. Our theory and empirical evidence provide significant insights into the complex relationships among compensation schemes, executives' characteristics, firm performance, and managerial behaviors.

Entrepreneurship researchers have yet to explore the full range variance that occurs in entrepreneurial value creation because we have focused almost exclusively on financial performance as the dependent variable in our research. However, such arbitrary narrowness is not supported by research, which shows entrepreneurs to not focus exclusively on income maximization. Consistent with calls for an expanded view of the consequences of entrepreneurship, we develop a typology of entrepreneurship dependent variables that supports broadening the scope of entrepreneurship research to include economic, environmental and social value.

Bondholder Wealth Effects in Mergers and Acquisitions: New Evidence from the 1980s and 1990s 总被引:3,自引:0,他引:3
We examine the wealth effects of mergers and acquisitions on target and acquiring firm bondholders in the 1980s and 1990s. Consistent with a coinsurance effect, below investment grade target bonds earn significantly positive announcement period returns. By contrast, acquiring firm bonds earn negative announcement period returns. Additionally, target bonds have significantly larger returns when the target's rating is below the acquirer's, when the combination is anticipated to decrease target risk or leverage, and when the target's maturity is shorter than the acquirer's. Finally, we find that target and acquirer announcement period bond returns are significantly larger in the 1990s. 相似文献
