他们为什么出去?又为什么回来?他们都在哪儿?过着什么样的日子?上个世纪90年代出国的“海归”中,他们学历普遍是博士以上,现在更多的人是在做研究;而新世纪出国的“海归”,外面闯荡的经历则更多的给了他们创业的动力和激情。相同的是,他们都被济南特有的文化所吸引。  相似文献

Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.  相似文献

Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless.  相似文献

The United States (US) exports more than US$6 billion in agricultural commodities to the European Union(EU) each year, but one issue carries the potential to diminish this trade: use of biotechnology in food production. The EU has adopted more stringent policies towards biotechnology than the US. Understanding differences in European and American policies towards genetically modified (GM) foods requires a greater understanding of consumers’ attitudes and preferences. This paper reports results from the first large‐scale, cross‐Atlantic study to analyse consumer demand for genetically modified food in a non‐hypothetical market environment. We strongly reject the frequent if convenient assumption in trade theory that consumer preferences are identical across countries: the median level of compensation demanded by English and French consumers to consume a GM food is found to be more than twice that in any of the US locations. Results have important implications for trade theory, which typically focuses on differences in specialization, comparative advantage and factor endowments across countries, and for on‐going trade disputes at the World Trade Organization.  相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment.  相似文献

We argue that the standard Constitutional Political Economy defence of constitutionalism, that derives from an argument relating to the shift from narrowly self-interested motivations in the in-period context to relatively general-interest decision making in the constitutional context, is flawed precisely because it is intended to relate to essentially political settings where decision making must be construed as collective in nature. We suggest an alternate account of expressive constitutionalism that points to a specific defence of constitutional conventions that are insulated from popular voting.  相似文献
