Livestock form key components of the livelihood strategies of many of the world's poorest people. However, despite the potential to alleviate poverty and improve food security through livestock development interventions, the lack of smallholders' participation in the planning and design of breeding programs has often been a major cause of the failure of such programs. Particularly in developing countries where livestock production is still mostly subsistence-oriented and livestock fulfil manifold functions a considerable number of livestock breeding programs have failed. The development of adequate tools to characterise these functions, bearing in mind that these are expressed only rarely in properly functioning markets, is therefore important.This paper seeks to advance the application of such methodologies to the smallholder pig sector in Vietnam. A choice experiment was applied across 140 households involved in pig breeding in order to assess farmers' preferences and the trade-offs for a list of adaptive and productive traits. These included growth, reproduction, disease resistance, feed requirements and appearance.The findings indicate that smallholders highly value both adaptive and performance traits, particularly in resource-driven (i.e. subsistence) production systems. Performance traits were more highly valued in the demand-driven (i.e. market-oriented) systems. These findings have implications for breeding program breed choice and breeding objectives.  相似文献

Using two unique confidential datasets summarizing the cross‐border lending of banks in France and the UK, we examine whether recipient‐country prudential policies can help to reduce the spillover effects of euro‐area (EA) monetary policy. We address this question from a novel angle, focused on the role of international financial centres, by considering differences in bank size and location (lending from French headquarters vs. from French affiliates located in the UK). For small French banks that lack a presence in international financial centres, the response of direct cross‐border lending from France to EA monetary policy is partially offset by recipient‐country prudential policy. For larger banks, however, the offsetting effect applies only to lending that passes through foreign affiliates located in London. This suggests the existence of a “London Bridge”: banks adapt their flows to the UK conditional on EA monetary policy and global prudential policies; and from their UK affiliates to third‐party countries in a manner that depends on local prudential settings.  相似文献

ABSTRACT 1 : A wide ranging set of reforms is being introduced into the English National Health Service (NHS). They are designed to increase the market‐like behaviour of providers of care with a view to improving efficiency, quality and responsiveness of services. This paper is concerned with one aspect of those reforms: namely the policy to increase the diversity of types of providers of care to NHS patients. In this context, increasing diversity means that providers will not all be standard publicly owned NHS organizations. They can be publicly owned but autonomous, or independent (both in for‐profit and not for profit). The paper discusses the wide range of organizational forms available, analyzing their governance structures It then discusses the small amount of evidence currently available about the performance of diverse providers of health care.  相似文献

Countries with intermediate levels of institutional quality suffer larger output contractions following sudden stops of capital inflows than less developed nations. However, countries with strong institutions seldom experience significant falls in output after capital flow reversals. We reconcile these two observations using a calibrated DSGE model that extends the financial accelerator framework developed in Bernanke, Gertler and Gilchrist (1999). The model captures financial market institutional quality with creditors' ability to recover assets from bankrupt firms. Bankruptcy costs affect vulnerability to sudden stops directly but also indirectly by affecting the degree of liability dollarization. Simulations reveal an inverted U-shaped relationship between bankruptcy costs and the output loss following sudden stops.  相似文献

Abstract.  This paper provides a model of involuntary unemployment by combining the insights of the sticky wage theory and the efficiency wage theory. It implies that employed workers tend to supply more effort in response to economic downturns. Thus, a negative shock to an economy has intriguing impacts on the unemployment. The model also shows that a negative demand shock may have a relatively small effect on output since changes in work effort serve to partially mitigate the effects of the shock. Moreover, it yields some implications that complement the existing 'work sharing' literature.  相似文献

We examine how offering digital content affects demand for print magazines. Using a searchable website archive, we measure the digital content offered by a sample of US consumer magazines from 1996 to 2001. We find strong evidence that digital content cannibalizes print sales. On average, a magazine’s print circulation declines about 3–4% when it offers a website. However, the effect varies with the type of digital content offered. Offering digital access to the entire contents of the current print magazine reduces print sales by about 9%. We find no evidence that digital content complements print magazines. These results are robust to including controls for unobserved magazine, category, and time effects, as well as controls for the impact of contemporaneous price changes and other factors.  相似文献

The rise of China is challenging the international financial architecture in a number of ways. This paper highlights three that are of critical importance: the challenge of absorbing massive Chinese savings; the incorporation of China into a cohesive global financial safety net; and the organisation of China's participation in funding the demand for international investment projects. The global financial architecture needs to be reformed. But what role should China play? The paper defines the options open to China and the opportunities and barriers it will face. We argue that China can work with the established economic powers in reforming the existing architecture. At the same time, China seeks cooperation in building new institutions and organisations that fill gaps in the existing arrangements. But no matter how international financial diplomacy plays out in the near term, deep financial and economic reform at home will alone deliver China a central role in the international financial architecture. Domestic reform could also attend to some of the challenges that currently plague China's impact on the system. The success or failure of these domestic reforms will be at the crux of the strength or fragility of the international financial architecture in the years ahead.  相似文献
