The purpose of this paper is to estimate athletic performance profiles over time, to establish that diminishing returns is a characteristic of performance functions, to measure the rate of the marginal decline, and to measure the upper (lower) bound or limit of performance. The empirical results yield estimates of the limiting value of athletic performance and the frontier maximum (minimum) record. Since lower bounds in the running events have been shown to be sensitive to choice of the nonlinear model, logistic and an exponential model for the men's running and distance events are estimated as a cross-check on my differential equation model. The issue of the gender gap (whether women will ever catch men) in athletic performance is also explored. 相似文献

A macroeconomic model is developed in which the psychological concept of loss aversion is incorporated into workers' preferences. The impact of monetary policy in the presence of loss aversion depends on the specification of the reference wage. The plausible specification that a worker's reference wage is the real wage she was paid in the previous period is considered in detail. Specifying the reference wage in this way, we show that an unanticipated change in monetary policy has a permanent, real effect when short term labour contracts are written in nominal wages. 相似文献

This note is a reply to Professor Kennedy's criticism of the specification of my model on taxation and economic growth and my testing of the degree of homogeneity of the growth-generating function in an earlier paper in this journal. I find that the model relating the pattern in the growth rate to the pattern in the division of the share of output is not affected by incorporating factor inputs into the model, that the function is homogeneous of degree one, and that the growth-maximizing tax rate of about 20 percent of GDP stands, as in the original paper. 相似文献

Student Workload and Assessment: Strategies to Manage Expectations and Inform Curriculum Development
AbstractThis study reports the results of a survey of student study times and perceptions of workload in undergraduate and graduate accounting courses at a large Australian public university. The study was in response to student feedback expressing concerns about workload in courses. The presage factors of student workload and assessment in Biggs’ 3P model are used because these factors can influence students' approaches to learning and therefore course improvements based on these factors could bring the greatest benefits. The findings suggest that the workload is not too heavy but that student perceptions of workload can be improved by clearer communication of teacher expectations and targeted course review to implement constructively aligned curricula. Initiatives implemented in assessment and to better match workload expectations between student and teacher are discussed and could be generalized to most courses. Areas for further research in student workload management are proposed. 相似文献
