A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate alternative management interventions. Data were collected from the Food Animal Health Resource Management System (FAHRMX), Today's Electronic Planning (TELPLAN), Today's Electric Farm Accounting (TELFARM) databases and secondary sources at Michigan State University. A case study of cystic ovaries was analysed using the model. The results showed that it is more economical to treat cystic ovaries than not to treat, and treatment with Gonadotropin Releasing Hormone (GNRH) was superior to Human Chrionic Gonadotropin (HCG). Four to five lactations were the optimum for keeping a dairy cow to replacement and it was estimated that there is a loss of US$0.45 per day of extended calving interval (days open beyond the optimal 70 days). 相似文献

All prestigious or highly-paid occupations in Britain are dominated by men: this is as true of the public sector as it is of industry. This article examines the evidence for discrimination in the public sector. It deals with both the situation at work and the one at home. It looks at various explanations as to why this is the case, as well as the evidence on how men and women deal with the inequality. The author concludes that there are good reasons why men and women do not see or confront the issues discussed in her article. Unless men and women wake up to the fact that we live in an unequal society and wish to see the glass ceiling well and truly broken, little is likely to change. 相似文献

Little is known about the differences in the relation between risk and return in large economies such as the U.S. compared with smaller, less studied, markets. In this paper, Sweden serves as a representative for small open economies. The price of risk on the Swedish stock market is estimated using a conditional asset pricing model that allows for time variation in the risk. Four different GARCH-M models are used in the econometric specification. The estimates of the price of risk are invariably positive and significant, and we conclude that there exists a time-varying risk premium in the Swedish stock market. Our results show that there are small differences in the preferences towards risk of representative investors in small and large economies. 相似文献

In this comment we identify the key features of the Frantz and Walker (1997) game theoretic model that drive the non-disclosure equilibrium result in their paper. We argue that, although technically correct, their model fails to capture certain aspects of real-world wage bargaining that will be important in determining optimal disclosure strategies in practice. However, Frantz and Walker's paper illustrates the potential of analytical techniques to contribute to the employee disclosure debate. 相似文献

Sustainable debt has become the key issue in rating of private as well as sovereign debtors. The problem of how to estimate sustainable debt has also been at the center of the debate over the Asian 1997–1998 financial crisis. If the external value of the currency depends on the external debt of a country, it is necessary to estimate the creditworthiness of the country. This paper studies credit risk and sustainable debt in the context of a dynamic model. For a dynamic growth model with an additional equation for the evolution of debt, we demonstrate of how to compute sustainable debt and creditworthiness. The model is estimated by employing time series data for the core countries of the Euro-area. The computations show that the Euro-area has large external assets. Using time series methods, the sustainability of external debt (assets) is estimated for those core countries of the Euro-area. Those estimations show that the Euro will be a stable currency in the long-run. 相似文献

The purpose of the Harvard Business School-Journal of Financial Economics conference was to reexamine the role of clinical work in our profession. Clinical research–empirical work that examines a relatively small number of events intensively–accounts for a very small fraction of published work in the field. The pieces in this conference volume are case studies of different “clinical” research techniques that are used to develop, test, apply and communicate theory. 相似文献

The present contribution analyzes the implications of two central factors influencing the asset allocation decision of (German) life insurance companies, the development of the equity market on one hand and the interest rate guarantees included in traditional life insurance products on the other. The adverse development of share prices in 2000–2002 implies the necessity to consider not only ?normal“ volatility but also worst case-developments for the purpose of risk control. Formally this is done by using the risk measures value-at-risk and conditional value-at-risk. The specific ?myopic“ nature of interest rate guarantees in German life insurance products, which are granted on a yearly basis implies — beyond the general control of the shortfall risk with respect to the guaranteed interest rates — the necessity to per-form the asset allocation on a yearly basis to be in conformity with the time horizon of the liabilities.On the basis of a quantitative approach corresponding model calculations are performed. Thereby not only a pure market valuation is considered but also institutional peculiarities (hidden reserves, accounting norms) of German life insurance companies. The possibility of a riskless one-year investment, either based on market values or on balance sheet values, is revealed to be crucial for giving interest rate guarantees on a yearly basis. 相似文献

This paper explores and investigates the role of branding within financial services. Specifically, the study aims to assess the importance of branding and its associated elements including brand image and brand experience in the relationships that exist between consumers and their financial brands. It aims to achieve this through research, which identifies gaps between the managerial and consumer perspectives on branding in relationships in retail financial services. It is well established that the characteristics of services are different from those of manufactured goods and that service personnel play a central role in the services experience. Moreover, the concept of relationship marketing within services proclaims the importance of one-to-one relationships between businesses and customers as well as relationships between consumers and their brands. Drawing from the fields of brand management, relationship marketing and services marketing, this research aims to investigate the perceptional differences between consumers and suppliers in relation to the importance of branding in financial service relationships. The research findings indicate that brand experience appears to be far more salient than brand image in shaping and building meaningful and lasting brand perceptions and promoting customer retention. 相似文献

The focus of this discussion is on the empirical implications of Yee (2004, this issue). Yee's key contribution is the introduction of belief dependency into the model developed in Ohlson (1995), Feltham and Ohlson (1995, 1996), and Ohlson and Zhang (1998). Yee's primary conclusion is that accruals that do not incorporate beliefs about unobservable information lead to contemporaneous accounting data that are not sufficient for valuation but often belief-free accruals can lead to forward earnings that may be valuation sufficient. Yee (2004) provides an alternative theoretical model of the relation between firm value, trailing earnings, and forward earnings. This model may be used (1) to re-interpret the results of numerous empirical studies of the relation between market metrics, trailing earnings, and forward earnings, and (2) as the basis for framing further hypotheses and empirical studies. 相似文献
