This study provides a comprehensive examination of recent mutual fund performance by analyzing a large set of both mutual funds and fund attributes in an effort to link performance to fund-specific characteristics. The results indicate that the hypothesized relationships between performance and the explanatory variables are generally upheld. After taking into consideration general market conditions and fund investment objective, the characteristic variables that relate to fund popularity, growth, cost, and management also explain performance. Finally, after controlling for survivorship and benchmark error as well as fund-specific factors, the results refute the performance persistence phenomenon. 相似文献

This paper investigates quantitatively how initial wealth holding differences across households are propagated through time in a one sector growth model economy. A key feature of the model is that household consumption cannot fall below a positive level each period. The existence of a minimum consumption requirement implies that the Intertemporal Elasticity of Substitution not only differs across households but also changes differently over time. This model is calibrated to match some key aggregate statistics of the U.S. economy. We find that, as in the data, the wealth distribution in our benchmark model economy exhibits a (brief) period of increasing inequality, a short period in which inequality diminishes and a steady level of inequality along the balanced growth path. However, our model illustrates that the evolution of inequality is very sensitive to the length of the transition path. Additionally, our model predicts an upsurge in wealth inequality following the productivity slowdown in the 1970s. 相似文献

Galí and Gertler [1999. Inflation dynamics: a structural econometric approach. Journal of Monetary Eonomics 44(2), 195-222] developed a hybrid variant of the New Keynesian Phillips curve that relates inflation to real marginal cost, expected future inflation and lagged inflation. GMM estimates of the model suggest that forward-looking behavior is dominant: the coefficient on expected future inflation substantially exceeds the coefficient on lagged inflation. While the latter differs significantly from zero, it is quantitatively modest. Several authors have suggested that our results are the product of specification bias or suspect estimation methods. Here we show that these claims are incorrect, and that our results are robust to a variety of estimation procedures, including GMM estimation of the closed form, and nonlinear instrumental variables. Also, as we discuss, many others have obtained very similar results to ours using a systems approach, including FIML techniques. Hence, the conclusions of GG and others regarding the importance of forward-looking behavior remain robust. 相似文献

So far relatively little is known about the situation of Ph.D. students in media and communication research. The main purpose of this study is, therefore, to shed light on the employment and working conditions for young scholars on their way to their doctoral degrees. We conducted a survey of 281 Ph.D. students in Germany, Switzerland and Austria. The results show that, on the one hand, young scholars are intrinsically highly motivated to do their jobs. On the other hand, they perceive an academic career as a very uncertain venture with many obstacles. Furthermore, several types of Ph.D. students can be distinguished: idealists, careerists and waverers. It is shown that only the idealists conform to the concept of a productive and interested scholar. The results are discussed in terms of their importance for the future development of the field. 相似文献

The adoption of information technology in the sales force 总被引:1,自引:0,他引:1

The purpose of this article is to explain why salespeople adopt information technology. The results from a cross-sectional study of 229 salespeople indicate that putting sales technology to use strongly depends on salespeople's perceptions about the technology enhancing their performance, their personal innovativeness and organizational efforts in terms of user training. Throughout the adoption process companies also need to target sales line managers-next to end users-because salespeople clearly comply with the expectations of their supervisors. Finally, the threat from competing sales professionals or peers who use similar sales technology seems to be of secondary importance for individual sales technology adoption. 相似文献

This study examines the contribution of Raymond J. Chambers to the British inflation accounting debate in the early‐to‐mid 1970s, from the perspective of the reception of his book, Securities and Obscurities: A Case for Reform of the Law of Company Accounts, published in 1973. To structure the empirical narrative, drawing on previously unpublished documents from the R. J. Chambers Archives, we employ Czarniawska and Joerges’ ( 1996 ) notion of the ‘travel of ideas’, and Mumford’s ( 1979 ) observation of the existence of ‘inflation accounting debate cycles’. The result is a narrative that traces the environmental and material circumstances that led to Chambers’ book having a lesser impact on the British inflation debate than one would expect based on the international exposure of his ideas, his influence at the time, and the empirical rigour of his proposal. The purpose of this exercise is to assess how contextual factors, such as the choice of publisher, use of promotional material, and distribution methods, can be as (or more) important than the substance of the proposed ideas, arguments, and solutions. 相似文献
