There is a growing policy focus in Australian higher education on quantitative research performance assessment. However, most of the analysis has addressed aggregate performance at the institutional level, an approach inconsistent with recent policy emphasis on diversity among universities and one that ignores performance variations across disciplines. Using averaged and all available data for 2000–2004, cluster analysis is used to classify Australian Commerce Faculties into groups that exhibit similar research performance, measured by publication, PhD completion and secured competitive research grant funding. We also use factor analysis to generate full-multidimensional rankings within the resulting two or three clusters. It is found that in terms of total research output, with the exception of Adelaide all the Group of 8 (Go8) members plus University of Technology, Sydney and Griffith always belong to ‘Clusters A’. However, when research performance is expressed in per academic staff terms, an additional 11 universities join this same cluster. Our results additionally show that eight Australian faculties of Commerce not only possess low total research output but their per capita performance is also poor. 相似文献

Idea Competitions (ICs) are becoming a popular mechanism chosen by firms to perform Open Innovation. They are a way to engage with external sources of knowledge such as individual entrepreneurs and small firms who are asked to submit ideas and compete for a prize. However, little is known about the success of ICs as acquisition mechanisms. The researchers conducted interviews in five multinational companies to evaluate the effects of using ICs as an acquisition mechanism. Although still preliminary, the results of this study show that the success of ICs as an acquisition mechanism remains uncertain because their output (i.e. the number of ideas acquired) is often low compared to the input (i.e. the number of ideas submitted) and effort required to run them (e.g. to vet ideas). Across the cases observed, ICs appear to be more successful at identifying and acquiring early-stage ideas, particularly those outside the current business focus. The study shows that ICs deliver other functional benefits such as improved intelligence and public relations and that these need to be considered as part of the evaluation of the IC's success. The paper concludes by discussing the conditions in which ICs are implemented and the implications for Open Innovation theory. 相似文献

Financial frictions distort the allocation of resources among productive units—all else equal, firms whose financing choices are affected by such frictions face higher borrowing costs than firms with ready access to capital markets. As a result, input choices may differ systematically across firms in ways that are unrelated to their productive efficiency. We propose an accounting framework that allows us to assess empirically the magnitude of the loss in aggregate resources due to such misallocation. To a second-order approximation, the framework requires only information on the dispersion in borrowing costs across firms, which we measure—for a subset of U.S. manufacturing firms—directly from the interest rate spreads on their outstanding publicly-traded debt. Given the observed dispersion in borrowing costs, our approximation method implies a relatively modest loss in efficiency due to resource misallocation—on the order of 1 to 2 percent of measured total factor productivity (TFP). In our framework, the correlation between firm size and borrowing costs has no bearing on TFP losses under the assumption that financial distortions and firm-level efficiency are jointly log-normally distributed. To take into account the effect of covariation between firm size and borrowing costs, we consider a more general framework, which dispenses with the assumption of log-normality and which implies somewhat higher estimates of the resource losses—about 3.5 percent of measured TFP. Counterfactual experiments indicate that dispersion in borrowing costs must be an order of magnitude higher than that observed in the U.S. financial data, in order for misallocation—arising from financial distortions—to account for a significant fraction of measured TFP differentials across countries. 相似文献

AbstractAims: This trial-based economic evaluation (EE) assesses from a societal perspective the cost-effectiveness of an intensive 3-day cognitive theory-based intervention (CDT), compared to care-as-usual, in patients with relapsing remitting multiple sclerosis (RRMS) and low disability (Expanded Disability Status Scale [EDDS] score < 4.0).Materials and methods: The trial of the EE was registered in the Dutch Trial Register: Trial NL5158 (NTR5298). The incremental cost-effectiveness ratio (ICER) was expressed in cost on the Control sub-scale of the Multiple Sclerosis Self-Efficacy Scale (MSSES) and the incremental cost-utility ratio (ICUR) in the cost per Quality Adjusted Life Years (QALY) using the EQ-5D-5L. Bootstrap, sensitivity, and sub-group analyses were performed to determine the robustness of the findings.Results: The two groups of 79 patients were similar in baseline characteristics. The base case ICER is situated in the northeast quadrant (€72 (40.74/€2,948)) due to a higher MSSES Control score and higher societal costs in the CDT group. The ICUR is situated in the northwest (inferior) quadrant due to losses in QALY and higher societal costs for the CDT group (?0.02/€2,948). Overall, bootstrap, sensitivity, and sub-group analyses confirm the base case findings. However, when the SF-6D is used as a study outcome, there is a high probability that the ICUR is situated in the northeast quadrant.Limitations: The relative short follow-up time (6?months) and the unexpected increase in MSSES Control in the control group.Conclusions: When using the EQ-5D-5L to calculate a QALY, CDT is not a cost-effective alternative in comparison to care as usual. However, when using self-efficacy or SF-6D as outcomes, there is a probability that CDT is cost-effective. Based on the current results, CDT for patients with RRMS clearly show its potential. However, an extended follow-up for the economic evaluation is warranted before a final decision on implementation can be made. 相似文献

Film and television have been influential in the remaking of the American self since the traumas of Vietnam. We undertake readings of class, gender, ethnicity and race focusing on the roles of Martin Sheen and his two ‘crews’ in Apocalypse Now Redux and in the television series The West Wing. We argue that despite the appearance of a more progressive America as represented by the Bartlet White House it remains within a long tradition that represents the US in discourses of innocence and pureness of will and is largely blind to the kind of violence perpetrated by Willard and his crew in Apocalypse Now Redux. We suggest that the capacity of the US repeatedly to ‘forget’ its use of certain kinds of violence marks the limits of self-sacrifice of the American self and provides the discursive possibility for the eternal return of innocence. 相似文献

The effects on consumer welfare of requiring a utility facing cost or demand risk to use either a fixed retail price or marginal cost pricing are assessed. With marginal cost pricing and cost volatility an efficient futures market allows consumer welfare to be at least as high in every state as with the fixed price. With demand risk marginal cost pricing can benefit the consumer in every state without harming the firm if the profit difference is transferred to the consumer. A futures market can act as a partial replacement for the transfer. 相似文献

In an overlapping generations model with Cournot competition on the goods market it is shown that a continuum of stationary states and perfect foresight trajectories exists with unemployment at arbitrary low wages. Decisive for this is the influence that different forecast functions have on the objective demand curve, even though they are consistent with perfect foresight. With an example it is shown that simple adaptive and constant memory forecast rules generate such unemployment equilibria. The corresponding temporary equilibrium dynamics may display stable unemployment and unstable full employment equilibria.Journal of Economic LiteratureClassification Numbers: D43, D51, E24 相似文献

There are wide discrepancies in bilateral trade data compiled by China and by its trading partners, particularly the United States. This paper investigates the main reasons, notably the role of Hong Kong as an entrepôt, and develops a methodology to provide more accurate estimates for these trade flows. It extends the Sung—Lardy method in recent literature and achieves a reconciliation of the two data sets by China and by its major partners. The method recognizes that both the Chinese and the partners' data are likely to be distorted and demonstrates that a complete picture can he constructed by using data recorded from Hong Kong. A new estimate of the re-export margins in Hong Kong on Chinese exports is presented and used in the data reconciliation exercises, and problems of valuation and transit lag when comparing an export series with its counterpart import series are taken into account by the new method. The effects of using proved data are demonstrated in an application to examine fair market access in China—US bilateral trade undertaken by Tower (1993). 相似文献

By reexamining the effect of unemployment benefits on reemployment probabilities we make two contributions to the literature: first, we estimate separate effects for reemployment in the local or a distant region. Second, we address the problem of incomplete duration within a competing risks model. Our results confirm that missing data problems at first preclude any meaningful result even though we have access to daily individual data on 50 % of the male workforce in Germany. When we impose additional assumptions, we obtain evidence that the treatment effect depends on the household context, the treatment intensity and the destination state. 相似文献
