We analyse the effect of failing reinsurance cover on the stability of Dutch insurers. As insurers often reinsure themselves with other (re)insurers, a firm's loss could spread contagiously through the sector. Using a unique and confidential data set on reinsurance exposures, we gain insight into the reinsurance market structure and perform a scenario analysis to measure contagion risks. Considering entities on a standalone basis, we find no evidence of systemic risk in the Netherlands, even if multiple reinsurance companies fail simultaneously. At group level our analysis points to the contagion risk of in-house reinsurance structures, given that such in-house reinsurance parties are generally not higher capitalised than other group members. 相似文献

Improving the sustainability of farms often incurs additional costs for farmers. These costs come from allocating land to the maintenance of the ecological processes (energy and material flows, natural population regulation) required for the agroecosystem to function. Since these costs are not recovered on the markets, farmers see a fall in profits, the financial viability of their farms is compromised, and they suffer the consequences of the environmental services they are providing. All this makes it essential to implement government policies designed to compensate farmers for their efforts. The issue of how to assess sustainability has generated widespread debate within ecological economics, specifically as to whether it is possible to place a monetary value on it and if so, how this should be done. In a previous article we showed that agrarian sustainability involves a land cost, therefore this cost can be translated into monetary values. The purpose of this study is to develop this concept in practical terms by applying it to organic farming. We calculated the land cost of agrarian sustainability (LACAS) in order to compare organic versus conventional management in olive farming, as this crop is grown extensively in Spain and other Mediterranean countries. The results show that the agro-environmental subsidy is not enough to encourage olive growers to make the conversion from conventional to organic methods, because the land cost of sustainability is not adequately offset. They also show that improving agroecosystems can allow the land to take on more functions without increasing the land cost. In our case, encouraging the multifunctionality of the land has permitted a reduction in this cost. The LACAS could be a useful tool, not only for drawing up government policies designed to support organic farming, but also for improving the sustainability of the agrarian sector. 相似文献

The purpose of this essay is to provide an alternative approach to studying the rhetoric of policy-oriented economics suggesting that the range of economic-policy possibilities is conditioned by the rhetoric of economics. To this end, Martin Feldstein's pro-privatization rhetoric will be compared to that of President Bush. In doing so, we will aim at showing that just as the political rhetoric of Social Security invokes the authority of "ideographs" such as personal ownership to draw on a society's ideological and cultural repertoire, economic rhetoric undertakes a similar task by employing "economic ideographs" like deadweight loss to resonate with fellow economists through an appeal to the implicit normative premises embedded in the language of economics. 相似文献

Emergency plans are the tangible result of the preparedness activities of the emergency management lifecycle. In many countries, public service organizations have the legal obligation to develop and maintain emergency plans covering all possible hazards relative to their areas of operation. However, little support is provided to planners in the development and use of plans. Often, advances in software technology have not been exploited, and plans remain as text documents whose accessibility is very limited. In this paper, we advocate for the definition and implementation of plan management processes as the first step to better produce and manage emergency plans. The main contribution of our work is to raise the need for IT-enabled planning environments, either at the national or organization-specific levels, which can lead to more uniform plans that are easier to evaluate and share, with support to stakeholders other than responders, among other advantages. To illustrate our proposal, we introduce SAGA, a framework that supports the full lifecycle of emergency plan management. SAGA provides all the actors involved in plan management with a number of tools to support all the stages of the plan lifecycle. We outline the architecture of the system, and show with a case study how planning processes can benefit from a system like SAGA. 相似文献

"Fragmentation", the relocation of processes or functions across countries in response to cost and other differences, has important implications for development. We discuss the drivers of fragmentation and map it for electronics and automotives in East Asia (EA) and Latin America. For technical reasons, electronics is fragmenting faster world-wide than the auto industry. Electronics networks are more advanced, widespread and integrated in EA than Latin America and the Caribbean (LAC), and are largely responsible for EA's rapid export growth. The auto network is more advanced in LAC but is slower growing and is not integrated into a regional system. Apart from Mexico, LAC lacks an electronics network, partly accounting for the region's weak export performance. We offer insights into the following: Why do industries fragment differently? How can fragmentation be measured? Why does fragmentation in developing countries concentrate on EA and LAC? Why has fragmentation evolved differently in these two regions? Can other developing regions attract and benefit from fragmentation? 相似文献

Value chains linked to urban markets and agro-industry present new opportunities for adding value and raising rural incomes. Small farmers, who produce small volumes, struggle to enter these markets. A lack of trust among value chain actors increases transaction costs and short-circuits innovation. This paper explores how multi-stakeholder platforms have been used to address these problems in potato-based value chains in Bolivia, Peru and Ecuador. It uses the Institutional Analysis and Development (IAD) framework to understand how platforms work. Differences in characteristics of the value chains, the participating actors and institutional arrangements have led to the emergence of two types of platforms. The first type brings traders, processors, supermarkets and others together with farmer associations and research and development (R&D) organizations to foster the development of new market opportunities through commercial, institutional and technological innovation. The second type is structured around geographically delimited supply areas, meshing farmers and service providers to address market governance issues in assuring volumes, meeting quality and timeliness constraints and empowering farmers. Evidence from these cases indicates that platforms that bring stakeholders together around value chains can result in new products, processes, norms and behaviours that benefit poor farmers, which could not have been achieved otherwise. 相似文献

A double‐hurdle partial observability model of hire‐purchase lending is specified and estimated to test for racial discrimination by retailers of consumer durables during apartheid. ‘Discrimination’ is defined as supplying no loans or less desirable loans to certain borrowers, who do not differ from more successful borrowers with respect to creditworthiness but who do differ with respect to race. There is strong evidence of discrimination. In particular, black households are 13 percentage points more likely to desire a hire‐purchase loan but not to have one supplied to them than are other households equivalent in all ways except race. Although the statistical test cannot determine whether race affected lending because lenders were bigoted or because race is correlated with unobserved characteristics correlated in turn with creditworthiness, increased access to formal loans for all South Africans could be promoted by relaxing the Usury Act and by removing from loan applications information that could reveal an applicant's race. 相似文献
