In many parts of Europe, decades of production subsidies led to the steady intensification of agriculture in marginal areas. The recent decoupling of subsidies from production decisions means that the future of farming in these areas is uncertain. For example, in the uplands of the United Kingdom, an area important both for biodiversity conservation and ecosystem service provision, hill farmers steadily increased stocking densities in response to headage payments but must now reconfigure farm businesses to account for the shift to the Single Farm Payment scheme. We examined hill farming in the Peak District National Park as a case study into the future of marginal agriculture after decoupling. We surveyed 44 farm businesses and from this identified six representative farm types based on enterprise mix and land holdings. We developed linear programming models of production decisions for each farm type to examine the impacts of policy changes, comparing the effects of decoupling with and without agri-environment and hill farm support, and evaluating the effects of removal of the Single Farm Payment. The main effects of decoupling are to reduce stocking rates, and to change the mix of livestock activities. Agri-environmental schemes mediate the income losses from decoupling, and farmers are predicted to maximise take up of new Environmental Stewardship programmes, which have both positive and negative feedback effects on livestock numbers. Finally, removal of the Single Farm Payment leads to negative net farm incomes, and some land abandonment. These changes have important implications for ongoing debates about how ecological service flows can be maintained from upland areas, and how marginal upland farming communities can be sustained.  相似文献

The lineages of the entrepreneurial ecosystem approach   总被引:1,自引:0,他引:1  
In its most abstract sense, an ecosystem is a biotic community, encompassing its physical environment, and all the interactions possible in the complex of living and nonliving components. Economics has always been about systems that explain differential output and outcomes. However, economics has generally ignored the role of entrepreneurship in economic systems, just as entrepreneurship studies have largely overlooked the role of systems in explaining the prevalence and performance of entrepreneurship. The entrepreneurial ecosystem approach has the promise to correct these shortcomings. Its two dominant lineages are the regional development literature and the strategy literature. Both lineages share common roots in ecological systems thinking, providing fresh insights into the interdependence of actors in a particular community to create new value. But studies of both regional development and strategic management have largely ignored the role of entrepreneurs in new value creation. In this paper, we will outline contributions to the entrepreneurial ecosystem approach and conclude with a promising new line of research to our understanding of the emergence, growth, and context of start-ups that have achieved great impact by developing new platforms.  相似文献

American capitalism differs from all other forms of industrial capitalism is its historical focus on both the creation of wealth (entrepreneurship) and the reconstitution of wealth (philanthropy). Philanthropy is part of the implicit social contract that continuously nurtures and revitalizes economic prosperity. Much of the new wealth created historically has been given back to the community, to build up the great social institutions that have a positive feedback on future economic growth. This entrepreneurship-philanthropy nexus has not been fully explored by either economists or the general public. The purpose of this paper is to suggest that American philanthropists – especially those who have made their own fortunes – create foundations that, in turn, contribute to greater and more widespread economic prosperity through knowledge creation. If we do not analyze philanthropy we can understand neither how economic development occurred nor what accounts for American economic dominance.  相似文献

An empirical test is provided of the effect of the degree of obsolescence on the effect of firm size and monopoly profits on a firm's ability to innovate. Recent theory suggests that innovation depends on firm size and monopoly profits only if the firm conducts product improvement as well as new product innovation. This is due to the allocation of limited entrepreneurial attention between improving current products and innovating new products. Current products are subject to obsolescence and innovation requires technological opportunities. The firm conducts product improvement as well as new product innovation only if the degree of obsolescence is sufficiently low relative to the level of technological opportunity. This theory provides an explanation for previously unexplained empirical observations. We find preliminary support for the hypothesis that product improvement reduces the positive effect of firm size on new product innovation and sufficient product improvement may reverse the negative effect of monopoly profits on new product innovations. In addition, product improvement reduces the positive effect of technological opportunity on new product innovation.  相似文献

We develop an endogenous-growth model in which we distinguish between inventors and innovators. This distinction implies that stronger protection of intellectual property rights has an inverted U-shaped effect on economic growth. Intellectual property rights protection attributes part of the rents of commercial exploitation to the inventor that would otherwise accrue to the entrepreneur. Stronger patent protection will therefore increase the incentive to do research and development (R&D) and generate new knowledge. This new knowledge has a positive effect on entrepreneurship, innovation, and growth. However, after some point, further strengthening of patent protection will reduce the returns to entrepreneurship sufficiently to reduce the overall growth rate.  相似文献

We analyze conceptually and in an empirical counterpart the relationship between economic growth, factor inputs, institutions, and entrepreneurship. In particular, we investigate whether entrepreneurship and institutions, in combination in an ecosystem, can be viewed as a “missing link” in an aggregate production function analysis of cross-country differences in economic growth. To do this, we build on the concept of National Systems of Entrepreneurship (NSE) as resource allocation systems that combine institutions and human agency into an interdependent system of complementarities. We explore the empirical relevance of these ideas using data from a representative global survey and institutional sources for 46 countries over the period 2002–2011. We find support for the role of the entrepreneurial ecosystem in economic growth.  相似文献

What is an Entrepreneurial Opportunity?   总被引:3,自引:2,他引:3  
The nature and source of entrepreneurial opportunity are important issues for understanding how markets function and come into being. In addition to describing the forum held on the topic and summarizing the contributions of the articles that appear in the special issue, this article shares a number of lessons learned during the workshop and the editorial process. We explore three of the most important reasons for confusion about the opportunity construct: (1) the “objectivity” of opportunity, (2) the perceived importance of one particular individual in determining the direction of the social world and (3) what distinguishes the sub-class of “entrepreneurial” opportunity from the broader category of opportunity in general. Finally, we offer some directions for future research by illuminating important issues that emerged from the workshop but that remain largely unanswered by the papers of this special issue.   相似文献

A model is presented hypothesizing that the level of small-firm presence in any given industry emanates from the exogenous stock of entrepreneurial talent, a stochastic element of managerial and entrepreneurial talent, entry deterrence, and the entrepreneurial strategy deployed by small firms. Using data newly released by the U.S. Small Business Administration, the hypothesis is tested for a sample of 247 four-digit standard industrial classification industries, spanning the entire spectrum of firm sizes. We find that, consistently for all the measures of small-firm size and for all of the time periods used, the existence of entry deterrence and reliance upon innovative strategy explains a significant proportion of the variation in the presence of small firms.  相似文献
