The environmental Kuznets curve (EKC) hypothesis conjectures a nonlinear relationship between pollution and economic growth, such that pollution per capita initially increases as countries economically develop, but then reaches a maximum point before ultimately declining. Much of the EKC literature has focused on testing this basic hypothesis and, in studies that find evidence of an EKC, estimating the “turning point” level of development at which the per capita pollution‐growth relationship changes sign. This approach has not emphasized the policy relevance of specification issues or the potential role of policy variables. This research explores a modified EKC specification which conditions the pollution‐growth relationship on a country's level of debt and degree of democratization. These variables turn out to be significant, implying that different political and economic contexts can shift EKCs and their turning points. These findings suggest that policies to relieve debt burdens and institute political reform, in addition to their usual justifications, also could be used as a strategy to reduce carbon emissions from developing countries. © 2008 by the Association for Public Policy Analysis and Management. 相似文献

自从1979年中国实行改革开放以来,菲中两国的经济关系持续发展。菲律宾对华贸易要比它与世界其他国家的贸易增长得更快。近几年来,我们可以看到,由于菲律宾比素对人民币的比值相对较低,菲律宾对华出口骤增。尽管中国在菲律宾外贸总额中所占的份额已经由80年代的2%增长到现在的4%,但总的来说仍然偏少。 当前的菲中贸易结构以工业制成品为主体。正如其整体贸易结构一样,菲律宾的对华出口贸易以半成品为主。中国的工业制品则包含更多的制成品——电子产品、金属制品和建筑材料。近几年,在中国对菲律宾出口中消费品、食品及食… 相似文献

In this introduction, we review the literature on intellectual property rights and access to medicines, identifying two distinct generations of research. The first generation analyzes the origins of new intellectual property rules, in particular the World Trade Organization’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the significance of TRIPS to developing countries. The second generation examines national-level experiences, as countries adjust their laws and practices to conform to TRIPS. Based on the insights provided by the articles in the special issue, we contribute to the second generation by considering a pair of overarching sets of issues. First, we highlight the domestic political challenges that affect how countries go about implementing their new obligations under TRIPS. We argue that alliances and coalitions are necessary to underpin the use of policy instruments designed to conform to TRIPS while taking into account local conditions and needs, and we present insights that allow us to understand why alliances and coalitions are difficult to construct and sustain in this area. Second, we explain why policies that many countries adopt in response to TRIPS often do not generate their desired or intended outcomes. In the last section of the introduction, we review the articles that appear in this special issue. 相似文献
