Locational competition has intensified in recent years in the wake of globalisation as well as the general development towards
a knowledge- and service-based economy. In this context, newer economic analyses point to a shifting of the locational factors
considered relevant for success in local and regional competition. With respect to these fundamental changes, it is becoming
increasingly relevant to ask how local and regional development processes must be constructed in order for municipalities
and regions in modern industrial countries to maintain the positions they have already achieved. 相似文献

ABSTRACTThe notion of an ‘orthodox core–heterodox periphery’ structure and the extent of interdisciplinary links have been widely discussed, and partially investigated bibliometrically, within economic discourse. We extend this research by applying tools from social network analysis to citation data of three economics departments located in Vienna, two mainstream and one non-mainstream, to assess their relative citation patterns. We show that both mainstream economics departments follow the asserted core–periphery pattern and have a mono-disciplinary research focus, while the citation network of the non-mainstream department has a polycentric structure and is both more heterodox and interdisciplinary. These findings suggest that discussions about the future of heterodox economics should pay more attention to the organizational level and seek allies from other disciplines. 相似文献

Previous studies of the so-called frontier production function have not utilized an adequate characterization of the disturbance term for such a model. In this paper we provide an appropriate specification, by defining the disturbance term as the sum of symmetric normal and (negative) half-normal random variables. Various aspects of maximum-likelihood estimation for the coefficients of a production function with an additive disturbance term of this sort are then considered. 相似文献

On a criterion of minimum asymptotic coefficient bias, it has been shown recently [McCallum (1972), Wickens (1972)] that faced with a choice of using or discarding a (perhaps poor) proxy for an otherwise relevant independent variable which appears in a multiple regression model, one should always use the proxy. In this paper the analysis is expanded to consider variance in addition to bias in the criterion function. Our major finding is that although inclusion of the proxy is not a superior strategy unequivocally, it is recommended over a broad range of empirical situations. 相似文献

Recent economic literature criticises the size and mandate of public broadcasting in Germany. Technological progress has changed the methods of producing and distributing broadcasting content. Traditional broadcasting and print media have converged in a digital environment. Some of the classical arguments for publicly funded broadcasting have become invalid. This article argues that the converging media markets are nonetheless characterised by ongoing market failures, mostly because of positive external effects created by public value content. Markets will underprovide such content, which is why they should be publicly funded. We discuss the scope and form of public broadcasting and conclude that there are still economic reasons for dedicated public service broadcasters to exist. 相似文献
