Some small-holders are able to generate reliable and substantial income flows through small-scale dairy production for the local market; for others, a set of unique transaction costs hinders participation. Cooperative selling institutions are potential catalysts for mitigating these costs, stimulating entry into the market, and promoting growth in rural communities. Trends in cooperative organization in east-African dairy are evaluated. Empirical work focuses on alternative techniques for effecting participation among a representative sample of peri-urban milk producers in the Ethiopian highlands. The variables considered are a modern production practice (cross-bred cow use), a traditional production practice (indigenous-cow use), three intellectual-capital-forming variables (experience, education, and extension), and the provision of infrastructure (as measured by time to transport milk to market). A Tobit analysis of marketable surplus generates precise estimates of non-participants' 'distances' to market and their reservation levels of the covariates — measures of the inputs necessary to sustain and enhance the market. Policy implications focus on the availability of cross-bred stock and the level of market infrastructure, both of which have marked effects on participation, the velocity of transactions in the local community and, inevitably, the social returns to agroindustrialization.  相似文献

This edited volume makes a large and welcome contribution toour understanding of the history of entrepreneurial financein the United States. The focus of the volume is on innovationby both corporations and entrepreneurs. It examines all theimportant forms of financing, including wealthy individuals(who we now call angels), venture capital, government financingand debt. Scholars of many disciplines, including economics,finance, entrepreneurship, business history, and organizationalnetworks will find this volume to be of interest and the essayscan be read either selectively or globally. Lamoreaux and Sokoloff's introduction is a significant chapterin itself, providing a rich historical analysis of the riseof the U.S. patenting system. The editors also provide a  相似文献

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

Previous theoretical work suggests that it is appropriate to adjust the CAPM for information contained in analysts' earnings forecasts. This paper uses non-parametric statistical methods to test the relation between estimation risk and security returns. The evidence supports the theory that neglected firms earn abnormally high risk adjusted returns.  相似文献

Laser scanning is a very efficient way to generate realistic, high-resolution digital models of 3-D geological outcrops. This paper discusses the methodologies involved in the creation and analysis of virtual outcrops, based on laser scanner data. The visualisation of the laser scanner data as a photorealistic 3-D object is described. Geological features picked out on the virtual outcrop (e.g. fractures, faults or bedding planes) can be extrapolated outward, into space, and inward, into the subsurface, using tension surfaces.  相似文献

In this paper we examine the importance of systematic equity market factors in explaining the cross-sectional variation in yield spreads on corporate debt. Based on a sample of 1771 corporate bonds over the period from January 1985 to March 1998, we find that once the default-related variables are controlled for, bond betas or sensitivities to aggregate equity market risks have very limited explanatory power. This is in contrast to [Elton, E.J., Gruber, M.J., 2001. Explaining the rate spread on corporate bonds. Journal of Finance 56, 247–277] who find that market factors tied to expected returns are predominantly important, but who do not control for these variables (i.e. the relevant variables from structural models), possibly biasing their estimates. On the other hand, our finding that the systematic factors exhibit some limited explanatory power suggests that the standard contingent claims approach may not fully apply. This finding is consistent with previous research that bond betas are not completely irrelevant once market frictions are introduced. Overall, the evidence provides empirical support for the proposition that structural models capture important elements of corporate bond yield spread determination and equity market systematic factors are by no means predominant.  相似文献

Multinational Activity and CEO Compensation: Preliminary Evidence from Large UK Firms. — Since the early 1980s the rate of growth in executive remuneration has consistently outpaced that of average earnings. This phenomenon has been widely assumed to be part of an internationalization of the executive labor market. This paper starts from the premise that the multinational enterprise will be a major agent in such a market and presents some preliminary tests for the impact of multinational activity in general, and specific regional effects in particular, on CEO remuneration using a sample of large UK firms. Surprisingly, we find no evidence to support our conjecture that CEO pay will be positively related to firm involvement in the United States. However, multinational activity does generate a significant premium over purely domestic activity.  相似文献

The secularization of science, by analogy with the separation of Church and state, would divest all science funding from the state, except where it bears directly on matters of public policy. I argue for an intensification of this tendency, which is already occurring across the Euro-American world. I then explore the policy implications in some detail, including historical precedents in New Deal attitudes toward the role of science in public policy. I begin by reviewing the secularization of Christendom, which turns out to be intimately tied with the social ascendency of the natural sciences. I then explore more recent conditions that contribute to the secularization of science itself, during which I claim that the Cold War's scaling up of state support for scientific research should be regarded as a historical aberration that we are currently getting over. However, I still reserve a very strong role for the state in the public distribution of already existing knowledge, the primary vehicle for which will remain the university.  相似文献
