Synopsis The Neo-classical approach to fisheries management is based on designing and applying bioeconomic models. Traditionally, the
basic bioeconomic models have used pre-established non-linear functional forms (logistic, Cobb–Douglas) in order to try to
reflect the dynamics of the renewable resources under study. This assumption might cause misspecification problems and, in
consequence, a loss of predictive ability. In this work we intend to verify if there is a bias motivated by employing the
said non-linear parametric perspective. For this purpose, we employ a novel non-linear and non-parametric prediction method,
called Genetic Algorithms, and we compare its results with those obtained from the traditional methods. 相似文献

Notwithstanding their common features, hedge funds remain an extremely diverse asset class. Information on fund styles is important for numerous purposes, such as portfolio construction, performance attribution and risk management. With fund self‐declaration being prone to (strategic) misclassification, return‐based taxonomies grouping funds along similarities in realized returns provide a useful alternative. We provide a consistent classification system of homogeneous groups of hedge funds based on self‐organizing maps. Whereas some fund categories such as managed futures are largely consistent in their self‐declared strategies, others, especially so‐called ‘equity hedge’ funds, display no or very limited return similarities. Furthermore, we also find evidence of fund managers performing undisclosed changes of their trading style over time. Those funds that misclassified themselves once are particularly likely to change their trading style again. Although style self‐declaration can, therefore, be quite misleading, our results indicate that hedge funds do not misdeclare their style strategically to improve their relative performance.

This paper measures the degree of concentration and competition in the enlarged European Union (EU) banking environment over the period 1998–2002. In the empirical part we opt for a methodology as proposed by Panzar and Rosse based on a non‐structural estimation of market competition. Our results suggest that European banks were operating under conditions of monopolistic competition and that bank interest revenues in the 10 new EU member states was earned under conditions of higher competition than those that existed in the old EU banking countries. The opposite result was observed for total operating revenues. Smaller banks earn interest income in a less competitive environment than larger banks, while the opposite is observed for total revenues. 相似文献

Policy makers have traditionally considered the macroeconomic relations and the variables that can affect the economic objectives that they pursue, such as prices, employment, balance of payments, and economic growth. Recently, microeconomic behavior has also been considered. To complete the analysis, it is necessary to include those variables that define the firm's evolution and activities, and cash flow could be this kind of variable to be included in the analysis. The main objective of this paper is to show the relationship between cash flow and one of the final economic policy targets, economic growth. This paper considers the relationship between cash flow and applied economics, then develops the effects of cash flow on economic growth. 相似文献

A thematic balanced scorecard format was used to address environmental and social performance evaluation of 13 large companies operating in Portugal. Financial aspects of environmental and social company activities are also included. Companies were categorized as to their actual performance status using a predefined performance framework. Three categories were found: compliance with the law while emphasizing pollution control, pollution prevention and eco‐efficiency. Management tools and procedural matters were found to be most relevant for categorization. Often, reported information did not allow for quantitative evaluation of environmental burden reduction. Use of the thematic balanced scorecard format was useful to better understand the strengths and weaknesses of links between objectives and measurements, initiatives and achievements. Improvement as to environmental performance was found to be paralleled by increased social performance, suggesting that a multi‐level ‘sustainability’ performance categorization of these Portuguese companies is feasible. Driving forces for environmental management initiatives were found to differ by category of performance. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment. 相似文献

This article studies the properties of optimal fiscal policy in a stochastic growth model when the government cannot commit itself beyond the next period's capital income tax rate. We find that the results contrast markedly with those under full commitment. First, capital income tax rates are very high (65% on average versus close to zero on average under full commitment). Second, labor income taxes are rather low on average (about 12% versus a value of around 31% under full commitment). Finally, labor income taxes are quite volatile, whereas under full commitment their standard deviation is essentially zero. 相似文献
