Moral entrepreneurship is the fine art of recycling evil into good by taking advantage of situations given or constructed as crises. It should be seen as the ultimate generalisation of the entrepreneurial spirit, whose peculiar excesses have always sat uneasily with homo oeconomicus as the constrained utility maximiser, an image that itself has come to be universalised. A task of this essay is to reconcile the two images in terms of what by the end I call ‘superutilitarianism’, which draws on the lore of both superheroes and utilitarianism. After briefly surveying the careers of three exemplars of the moral entrepreneur (Robert McNamara, George Soros and Jeffrey Sachs), I explore the motives of moral entrepreneurs in terms of their standing debt to society for having already caused unnecessary harm but which also now equips him with the skill set needed to do significant good. Such a mindset involves imagining oneself a vehicle of divine will, which would be a scary proposition had it not been long presumed by Christians touched by Calvin. In conclusion, I argue that moral entrepreneurship looks most palatable – and perhaps even attractive – if the world is ‘reversible’, in the sense that every crisis, however clumsily handled by the moral entrepreneur, causes people to distinguish more clearly the necessary from contingent features of their existence. This leads them to reconceptualise past damages as new opportunities to assert what really matters; hence, a ‘superutilitarian’ ethic that treats all suffering as less cost than investment in a greater sense of the good.  相似文献

This paper focuses on recent British experience with telematics-based Demand Responsive Transport (DRT) services in rural areas. In recent years, the ability of DRT concepts to provide efficient, viable transport services has been greatly enhanced by the use of transport telematics as demonstrated in a variety of environments across Europe. The success of British local authorities in winning substantial funding under the Rural and Urban Bus Challenge programmes for the implementation of DRT has resulted in widespread interest in flexible forms of transport. It is thus timely to evaluate the impact of this substantial investment. Drawing on the experience of a number of UK schemes, the paper assesses the reasons for the new-found success of what is becoming a relatively well-accepted mode by concentrating on a variety of factors including: service characteristics (particularly route flexibility, flexibility of booking method and pre-booking regime), emerging markets and the overall contribution of DRT to increased social inclusion and intermodality. Impediments to the development of DRT services are highlighted. The paper also discusses current research into the next generation of DRT services and concludes by identifying some key issues for policy-makers concerned with the future implementation of DRT services.  相似文献

Soil water and nutrients are critical drivers of crop production for smallholders of southern Africa. A three-year study was conducted to assess the effect of integrating single and double ploughing, ripping and planting basins with nitrogen fertilizer (0, 10 and 20?kg?N?ha–1) on soil water dynamics and maize (Zea mays L.) yields. The experimental design was factorial with four tillage methods and three nitrogen levels as treatment factors. The study was conducted under semi-arid conditions of Zimbabwe. Tillage methods had similar soil water patterns in the profile and no tillage?×?N interaction effects were observed on soil water dynamics. Soil water penetrated deeper into the profile under ripper and basin methods than conventionally ploughed treatments. Nitrogen increased maize yields (14–96%) and rainwater-use efficiency (20–92%) regardless of tillage methods and growing season quality. However, more studies are required to explore complementary techniques that can improve rainwater capture and prolong soil water storage, and improve soil fertility.  相似文献

Intermediaries play a crucial role in the functioning of agricultural and food markets in developing countries through linking production, imports and storage with consumption. We analyse how competition in the intermediary sector and alternative forms of intermediaries determine the incentives for storage and market outcomes more generally. We apply this framework to the Egyptian wheat sector as an illustrative case study, a country where food security is a priority, where both forms of intermediaries co-exist and undertake storage but where issues of reforms to the role of intermediaries have been raised. Through stochastic simulation, we analyse two changes in government policy: first, the effects of changing the policy instruments with both types of intermediaries undertaking storage; second, relating to market reforms where the private sector replaces the storage function of the parastatal. These issues have wider significance for addressing the interaction between food security and a wide range of policy reforms including de-regulation of parastatals in developing countries.  相似文献

This paper reviews what has been learned from experiences of African agriculture and hence what policy lessons may be. Views of African agriculture over the last 130 years have changed from optimism to pessimism and at least halfway back again as the performance of the sector has fluctuated. Fortunately it seems the deep pessimism about agricultural prospects expressed in the 1980s and 1990s has receded. The performance of African agriculture since 1990 suggests that neither those who doubt that any significant advances are taking place, nor those who see advances in some remarkable but perhaps isolated cases of rapid transformation of farming and agricultural supply chains, have sufficient evidence – either from national data or small‐scale studies – to support their positions. Hence policy has to rely largely on general principles and historic lessons, rather than more clearly proven propositions. Policy debates over African agricultural development may sharply divide on some topics, but there is little debate over the importance of basic conditions for agricultural development of an enabling investment climate and the provision of rural public goods. Beyond these basics, the challenge is to remedy the failings of markets that deny most smallholders access to inputs, financial services and insurance. Here opinion divides between whether to return to public provision, as with fertiliser subsidies, or whether private and collective institutional innovations will be sufficient. Recent initiatives to test and scale up the latter look promising, but most have yet to be evaluated. If agricultural development is first and foremost about establishing the basic conditions for growth, then most countries in Africa may be better placed than they have been in the past. Given the many examples that show African smallholders investing and innovating when they have the chance, then there are reasons to hope that the modest growth of production and productivity seen in the last two decades may accelerate in the future – thereby allowing African countries to make the transition from agrarian to urban economies.  相似文献

A recent innovation in management accounting is the practice of reporting unused capacity costs. This experimental study examines factors that affect when this practice improves decisions and when it impairs decisions. Reporting unused capacity costs uniformly leads experimental participants to cut unused capacity resources. Such cuts improve overall profitability when demand exhibits a negative trend. However, the cost savings from capacity reduction are more than offset by the increased opportunity cost of foregone demand when demand exhibits a positive trend. As such, this study suggests that explicit capacity cost reporting can be detrimental to growing companies.  相似文献

Using references in Swedish patent data, we examine technology sourcing in Swedish multi‐national enterprises (MNEs) and non‐multinational small and medium‐sized enterprises (SMEs). The results show that both types of firms are more likely to make references to countries with large patent stocks and to countries that are located close to Sweden. Trade and FDI also seem to facilitate the transfer of foreign technology to Sweden. However, trade contacts seem to be more important for technology sourcing in SMEs than in MNEs. Outward Foreign Direct Investment (FDI) is a channel for the diffusion of foreign technology to both home‐country MNEs and SMEs.  相似文献
