This paper presents a new method to examine the performance evaluation of mutual funds in incomplete markets. Based on the no arbitrage condition, we develop bounds on admissible performance measures. We suggest new ways of ranking mutual funds and provide a diagnostic instrument for evaluating the admissibility of candidate performance measures. Using a monthly sample of 320 equity funds, we show that admissible performance values can vary widely, supporting the casual observation that investors disagree on the evaluation of mutual funds. In particular, we cannot rule out that more than 80% of the mutual funds are given positive values by some investors. Moreover, we empirically demonstrate that potential inference errors embedded in existing parametric performance measures can be of important magnitude. 相似文献

This paper focuses on the organization of new product development in large, R&D‐intensive firms. In these firms, research and development activities are often separated. Research is conducted in dedicated research projects at specialized research labs. Once research results are achieved by research projects, they are transferred to business units for further development and commercialization. We investigate the speed whereby research projects transfer their first research results to business units (hereafter: transfer speed). In particular, we analyze the antecedents and performance implications of transfer speed. Based on data of 503 research projects from a European R&D intensive manufacturing firm, our results suggest that a fast transfer speed (as measured by the time it takes for a research project to develop and transfer its first research result to business units) is associated with a better research performance (as measured by the total number of transfers the research project generates). Moreover, we find that different types of external R&D partners—science‐based and market‐based partners—play distinct roles in speeding up project first research transfers. While market‐based partnerships (i.e., customers and suppliers) generally contribute to a faster transfer of first research results, science‐based partnerships (i.e., universities and research institutions) only speed up first research transfers of technologically very complex projects. Our results also show that early patent filings by research projects accelerate first research transfers. 相似文献

We examine whether the quality of restating firms’ management guidance differs in periods before and after restatement announcements. While characteristics of restating firms and the consequences of restatement have been a central topic in accounting and auditing research, the quality of management guidance around restatements is less well understood. We consider two competing characterizations of the link between management forecast accuracy and bias and restatement (an event that tends to signal poor financial controls): “Forecast–Opportunism Explanation” and “Forecast–Ability Explanation”. Under the Forecast–Opportunism Explanation, pre‐restatement weaknesses in financial controls enable managers to manipulate earnings toward forecasts and to meet or exceed opportunistically biased forecasts, and the post‐restatement strengthening of financial controls constrains opportunistic behavior. Under the Forecast–Ability Explanation, pre‐restatement weaknesses in financial controls impede managers’ ability to issue accurate forecasts, and post‐restatement improvements remove impediments so that the accuracy of forecasts improves; forecast bias remains unaffected. Evidence indicates that before a restatement, restating firms’ forecasts are more accurate and relatively more downwardly biased than control firms’ forecasts. Post‐restatement, restating firms have less accurate and less downwardly biased management guidance. Our overall results are consistent with the Forecast–Opportunism Explanation. 相似文献

Loss firms are an economically significant and growing segment of the population of publicly traded corporations. Relatively little is known about the tax positions of loss firms because the firms are typically dropped from tax avoidance studies. We develop a new measure of corporate cash tax avoidance that is meaningful for all observations and reflects the extent to which a firm is tax-favored. We examine the extent to which inferences about corporate tax avoidance over the past twenty-seven years change when we examine the full population of firms, as opposed to a profitable and/or taxable subsample. In contrast to prior research findings, our results suggest that on average firms are tax-disfavored, by which we mean cash taxes paid exceed the product of the firm’s pre-tax book income and the statutory tax rate. In addition, many industries that appear to be tax-favored in profitable subsamples are tax-disfavored when the entire population is examined. We also find that the extent to which firms are tax-disfavored is increasing over time, and that domestic firms are more tax-disfavored than multinationals. 相似文献

On the basis of historical data aggregated over the period 1973 to 2000, we have experimented with four different approaches to estimate the synthetic euro's equilibrium exchange rate. Using a number of competing models with the same data set, variable definitions and sample period offers the possibility to assess the uncertainty surrounding such equilibrium levels, both from an empirical (different estimates) and a theoretical viewpoint (different specifications). In this exercise, the 'Rest of the World' is proxied by the US, the UK, Japan and Switzerland, aggregated on the basis of trade weights.
We employed reduced form co–integration models, a structural VAR, a NATREX model (estimated in structural form) and the ECB's small–sized euro area wide macro–econometric model. In this order the approaches feature an increasing degree of 'structure', in the sense of the constraints based on economic theory embedded in the econometric models that were estimated. The results confirm the high likelihood for the euro having been undervalued in Q4 2000, while stressing the significant empirical and theoretical uncertainty with respect to the equilibrium exchange rate level. 相似文献
