This paper demonstrates howadditional rents are generated in a fisherycharacterized by intraseasonal variation infish characteristics, including size,condition, and composition. Based on anexpanded conceptual model of the optimalharvest rule, fish characteristics affect preand post harvest production yields and outputprices. A dynamic empirical model, which uses asystem of quality characteristics and anhedonic equation, illustrates the complexrelationships and management choices associatedwith internalizing seafood qualitycharacteristics in a hake fishery. The modelretains the regulated open access managementsystem, but controls intertemporal andintersectoral quotas, production portfolios,and total allowable catch. Results demonstratethat including revenue-side effects frominternalizing fish quality can generatesignificantly greater rents and reduce therelative benefits of increased productionyields. If excluded, bioeconomic models canunderestimate the level of regulatory rentdissipation and overemphasize managementobjectives such as full utilization, whichcould misdirect processing decisions and resultin a suboptimal resource management plan.Implications for data collection,multidisciplinary analysis, and improvements inmarine resource management are discussed.  相似文献

The first objective of this article is to clarify which model best captures the structure and trend of the influence of social origin on children's education. The second objective is to analyse how general conclusions on historical trends in educational reproduction change if we add mother's status background to the model. Six contrasting hypotheses are derived fromthe body of literature dealing with models on families' socioeconomic status. All hypotheses are translated into empirical models and their explained variance is compared. A pooled data set is used that contains data from the Netherlands, West Germany, and the USA. The Modified Dominance Model, that distinguishes the influence of the highest from thelowest status parent, has the best model fit. Regarding the second objective we see that adding the mother's influence to that of the father's does not change general conclusions on trends in educational reproduction. Over time the influence of both parents decreases continuously. However, the influence of the mother's education and occupational status on children's educational attainment is substantive.  相似文献

The evidence presented in the paper rejects the twin deficit hypothesis for the Austrian current account balance during the last two decades. The results are based on an estimate of a vector error correction model including quarterly data for the current account balance and potentially relevant variables driving its dynamics. We compute the variance decomposition of the current account's forecast error and its generalized impulse responses to shocks in the innovations of the system. The results in favor of intertemporal expenditure reallocation cannot be reproduced within a second analysis including the current account and a measure of net output, however. The estimated implicit current account balance, interpreted as the discounted expected change in future net output, does not follow the actual behaviour of the current account.

Brand managers exhibit considerable effort to define intended brand associations to anchor in consumers' minds. They follow a credo deeply rooted in branding literature: intended brand associations drive consumer response and brand equity. This article investigates the benefits of a strong overlap of actual consumer brand associations and management-intended brand associations (brand association match). The article presents results from two large-scale studies (3353 and 1201 respondents) involving one consumer goods and one service brand with multiple operationalizations of consumer response (attitudinal and behavioral). The results show that consumers with high brand association match show more positive brand response. However, after accounting for the valence of associations match does not add explanatory power. This outcome challenges a key foundation of brand management. The discussion identifies reasons why match may not be necessary to achieve response and provides arguments why the results do not imply free play for brand managers.  相似文献

The reorientations of energy policy, and in particular the promotion of renewables, have changed the market conditions for energy companies significantly. Over recent years, the resulting challenges put the energy companies’ financial ratios under severe stress. As the need to invest remains urgent, energy firms seek to broaden and diversify their sources of funding. Against this backdrop, the article addresses an innovative form of securities-based debt financing for energy companies, which explicitly links the financing transaction to the investing of funds in renewable energy projects. Due to the early stage of development of so called green (project) bonds, an initial disambiguation is essential. Thereafter, current market processes, structures and rules are considered. Based hereupon, it is possible to discuss the new opportunities that green project bonds afford energy companies.  相似文献

Mobil im Alter     
Selbstst?ndigkeit f?rdern - Mobilit?t ist die F?higkeit, sich in seiner Umgebung frei zu bewegen und die Aktivit?ten des t?glichen Lebens unabh?ngig auszuführen. Im Alter ist sie eine wichtige Voraussetzung für ein selbstst?ndiges Leben. Oft entscheidet gerade die Mobilit?t darüber, wie sich für den betagten Menschen die weitere Lebenssituation gestaltet.  相似文献

The information contained in a large panel dataset is used to date historical turning points and to forecast future ones. We estimate groups of series with similar time series dynamics and link the groups with a dynamic structure. The dynamic structure identifies a group of leading and a group of coincident series. Robust results across data vintages are obtained when series‐specific information is incorporated in the design of the prior group probability distribution. The forecast evaluation confirms that the Markov switching panel with dynamic structure performs well when compared to other specifications. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

This paper is concerned with the growth and development of two fields of study which are customarily separated in both theory and practice. Those who specialize in one area, whether as students, teachers or research workers, are not necessarily familiar with, or required to learn, the state of knowledge in the other, although, as we shall show, there is a considerable commonality of interest. To some extent, this situation is an accident of history and the first part of this paper deals with the events and influences leading to the emergence of each field of study. In the second part, common strands and factors leading to the convergence of the two fields are considered. The third section examines the “state of the art” and evaluates current strengths and weaknesses. Finally, an appraisal is made of the direction of likely future trends.  相似文献
