Guillaume Bernis 《Economic Theory》2002,20(2):295-320
Summary. This paper deals with the existence of equilibrium in a dynamic reinsurance market with short sale constraints, driven by
a marked point process, as studied in Bernis and Jouini (2001). We use the set of reinsurance treaties as consumption set,
which is the positive orthant of some Banach lattice that can be identified to a space of martingales, . The properness of preferences is a key assumption for us to prove the existence of an equilibrium. We provide a sufficient
condition for the preferences to be proper in term of loading factor of the reinsurance premium.

This review essay of Critical Essays on Piero Sraffa's Legacyin economics situates Sraffa's work in relation to the Marshalliantradition and neo-Walrasian general equilibrium theory, andreviews the current state of debate between adherents of thesetraditions on the role of demand, returns to scale, capitaltheory and policy analysis. Other issues considered includethe corn model, Sraffa's critique of Hayek, and the extensionof the capital theory critique to the intertemporal equilibriummodel. 相似文献

Trust and property rights are generally considered to influence farmers' behavior regarding resource use and environmental management. Previous studies show that higher trust levels may enhance contributions to public goods. This paper investigates how trust and (land) property rights security influence the provision of one concrete public good: land protection through the Sloping Land Conservation Program in China. The analysis is based on household survey data from Ningxia Autonomous Region in China. From our questionnaire two trust factors are derived and distinguished, using factor analysis: general trust and kinship trust. Farm households are less likely to contribute to public goods when they perceive more secure land rights, but trust has mixed effects on public goods. The results show that general trust and kinship trust may rely on two opposite effects for influencing public goods provision. On the one hand, high levels of general trust may directly enhance people's willingness to provide contributions to public goods (by reduced likelihood to reconvert forest land) when farmers are aware of the positive environmental effects of the program, that's the public goods effect. On the other hand, general trust may also make it more likely that people invest more in their own private goods to pursue their own welfare (a more likely reconversion of forest land to arable land), that's the private goods effect. The final outcome depends on the size and direction of both effects. Compared to general trust, kinship trust is more inward-looking and self- or group-interested compared to more reciprocal general trust. Thus, unlike general trust, kinship trust may have no significant public goods effect on the provisioning of public goods. 相似文献

T.R. Lakshmanan 《Journal of Transport Geography》2011,19(1):1-12
A major question in Economic Geography relates to the scale and nature of transport infrastructure’s contribution to the broader economy. While Cost-Benefit Analysis (CBA) is the most widely used of the three potential approaches, the recent interest in the wider economic benefits of transport infrastructure has spawned a variety of macroeconomic models. However, the estimates of magnitudes and direction of economic impacts of infrastructure by various macroeconomic models are sharply different, and these models shed little light on causal mechanisms linking transport and the economy. This paper has two aims: first, to highlight the wider economic benefits of transport infrastructure from the observed role of railroads and waterways in economic development, and two by reviewing recent theoretical developments to identify the multiple causal mechanisms which link transport and economic growth such as : market expansion, gains from trade, technological shifts, processes of spatial agglomeration and processes of innovation and commercialization of new knowledge in urban clusters (made possible by transport improvements). Hence the need for developing general equilibrium analyses of transport-economy linkages. 相似文献

Chingem模型是一个中国静态CGE模型.本文在Chingem模型的基础上,分析了2010年中国全面减免东盟原六国关税对中国宏观经济和产业的长期影响.在原模型的基础上,改进了宏观闭合条件.将原来作为剩余量处理的居民消费与居民收入联系起来,使经济增长会作用到居民消费,使模拟结果更加符合实际.研究表明全面减免对东盟的关税有利于我国经济的和谐发展;减少了经济增长对净出口的依赖;促进了进、出口商品结构的升级;促进了服务业的发展,但农业和制造业的一些部门会受到负面影响;制造业的就业会下降,服务业和农业的就业会上升. 相似文献

D.P. Vincent 《Economic Modelling》1985,2(1):17-32
A range of devaluation, monetary and wage policy mixes are analysed for the Chilean economy using a 10 sector comparative static model built along neoclassical lines. The model, while focusing on the real side of the economy, also contains a simple monetary sector. Quantifying the short-run implications of each policy mix for key macroeconomic and sectoral variables enables judgements to be made about the effectiveness of each mix in reaching specified targets and their feasibility. Money wage flexibility downwards is crucial if balance of trade and employment targets are to be achieved with lower domestic inflation and a smaller nominal devaluation. 相似文献
