In this paper we present a multi-disciplinary analysis of the potential impacts of undertaking similar environmental actions on multiple farms in a small geographic area, using organic farming as a proxy for a co-ordinated approach. Recent papers have called for more co-ordinated efforts between farmers in terms of their environmental actions, but there has been limited applied research demonstrating the environmental benefits or the economic and social implications to farmers of this approach. Comparative analysis of biodiversity, soil and water, and farm profitability were undertaken in England on 32 matched farms in areas of low and high organic farming concentration; qualitative interviews were also conducted with 48 farmers living in two of the eight areas. Findings demonstrate higher overall levels of biodiversity on organic farms (particularly in “hotspot” areas) but this was not universal across the species groups investigated. Higher water infiltration rates were found in organic grasslands, which could prove to be a useful measure to combat flooding. In terms of the technical efficiency of producing these environmental gains, conventional and organic farms in hotspot areas demonstrated equivalent efficiency from a financial perspective. Socio-cultural research identified the different amounts of trust farmers have in their neighbours, based in part on their performance as ‘good farmers’. We discuss the neighbourhood effect with a multi-disciplinary approach and conclude that encouraging local farmer co-ordination can have clear environmental benefits without high economic cost, but must be undertaken with caution - specifically regarding the trade-offs between benefits, local geophysical and social characteristics, and assumptions made about inter-farmer trust.  相似文献

This paper studies systemic risk in the Chinese debt market stemming from inter‐corporate loan guarantees using field data from Zhejiang Province. We apply a weighted and directed network model to analyse the implications for default contagion and systemic risk under different stress testing scenarios. The empirical results indicate that the topology of the loan guarantee network is close to a ‘scale‐free’ structure, which is known to be robust against accidental failures but vulnerable to coordinated attacks. Hence, the network is able to cope with idiosyncratic shocks resulting from single company failures, but can easily suffer from more widespread contagion if a group of systemically important companies are hit by a targeted shock. We further demonstrate that within our sample of small and medium‐sized enterprise (SME) companies, increasing leverage reduces network stability and exacerbates the effects of contagion. More lenient bank lending policies increase the survival rate of sample companies and thereby reduce the losses from default contagion.  相似文献

In view of high and persistent unemployment in the European industrialised countries there is growing consensus that more flexibility is needed with regard to both the legal and institutional conditions governing the labour market (external flexibility) and the management of human resources within individual firms (internal flexibility). This article examines the interaction between internal and external flexibility with special reference to wages, working time and job security.  相似文献

Die demografischen Ver?nderungen beeinflussen das Arbeitsangebot in den Regionen Deutschlands. Wie wird sich die Bev?lkerung nach Regionen differenziert bis 2020 entwickeln? Durch welche Faktoren wird die Arbeitsnachfrage beeinflusst? Welche Perspektiven ergeben sich daraus bis 2020 für die Raumordnungsregionen? Prof. Dr. Ulrich van Suntum, 52, ist Leiter des Instituts für Siedlungs- und Wohnungswesen der Universit?t Münster; Karsten Rusche, 26, Dipl.-Volkswirt, ist dort wissenschaftlicher Mitarbeiter.  相似文献

Drawing from research on strategic choice, this study investigates the relationship between market turbulence and firms’ sustainable behavior, in the context of sustainability-related institutional adversity. It argues that the relationship between market turbulence and sustainability is mediated by network embeddedness, and this mediating role in turn is moderated by a firm’s innovative orientation. Data collected from a sample of Ontario restaurants inform predictions about firms’ propensity to adopt local wines in their portfolios, despite the limited market and normative support that these wines receive compared with imported wines. The study shows that market turbulence enhances sustainable firm behavior, through the development of strong network relationships. Furthermore, the mediating effect of network embeddedness is particularly salient among firms that exhibit a stronger innovative orientation. These findings reveal how and when turbulent market conditions can contribute to a firm’s sustainable behaviors in the presence of limited institutional support for such behaviors.  相似文献

A questionnaire survey has found that most fund managers rely on the strategies of buy-&-hold, momentum and contrarian trading. These strategies are typically applied mutually. Their use is rooted in the attributes and beliefs of the respective fund managers: buy-&-hold traders are fundamentally oriented, risk averse and are less (over)confident than others. Momentum traders appear as the least risk-averse professionals, going aggressively with the trend. Contrarian traders, however, show signs of overconfidence and peculiar risk aversion, both indicating difficulties in successful strategy implementation. The behavioural patterns revealed are not easily reconciled with efficient markets.  相似文献
