There is increasing scientific evidence that natural systems are now at a level of stress globally that could have profound negative effects on human societies worldwide. In order to avoid these effects, one, or a number of technological transitions will need to take place through transforming processes of eco-innovation, which have complex political, institutional and cultural, in addition to technological and economic, dimensions. Measurement systems need to be devised that can assess to what extent eco-innovation is taking place. Environmental and eco-innovation have already led in a number of European countries to the establishment of substantial eco-industries, but, because of the general absence of environmental considerations in markets, these industries are very largely the result of environmental public policies, the nature and effectiveness of which have now been assessed through a number of reviews and case studies. The paper concludes that such policies will need to become much more stringent if eco-innovation is to drive an adequately far-reaching technological transition to resolve pressing environmental challenges. Crucial in the political economy of this change will be that eco-industries, supported by public opinion, are able to counter the resistance of established industries which will lose out from the transition, in a reformed global context where international treaties and co-operation prevent the relocation of environmentally destructive industries and encourage their transformation. 相似文献

This article presents analyses of the National Assessment Program – Literacy and Numeracy (NAPLAN) data and data on other indicators that are made available through the My School website. There are large differences across states and types of schools (independent, Catholic and government) in the Year 3 NAPLAN outcomes, though the differences across states tend to diminish as outcomes for later years of study are examined. Some schools are shown to consistently have academic outcomes better than their characteristics would otherwise indicate; conversely, other schools are shown to consistently have academic outcomes below the levels their characteristics would otherwise indicate. Few of these differences are statistically significant. 相似文献

Regulation and welfare: evidence from paragraph IV generic entry in the pharmaceutical industry 下载免费PDF全文

This article estimates welfare effects of accelerated generic entry via Paragraph IV challenges. Using data from 2000–2008 for hypertension drugs in the United States, we estimate demand using a random‐coefficients logit model. We find consumers gain $42 billion whereas producers lose $32.5 billion from entry. This modest $9.5 billion gain in social welfare is consistent with our observation that overall consumption does not increase after entry—generic sales displace branded sales, shifting surplus downstream from producers to consumers, insurance companies, and retailers. We demonstrate significant cross‐molecular substitution and discuss challenges in determining what fraction of downstream surplus actually goes to consumers. 相似文献

AbstractUnsignalized intersections in developing countries experience many serious conflicts between cross-traffic due to indiscipline traffic manoeuvrability. Historically, Post Encroachment Time (PET) has gained attention as a proximal indicator to analyze crossing conflicts. However, identifying an appropriate PET threshold to classify critical conflicts for highly heterogeneous traffic scenario is still an unexplored area. Consequently, this study proposes a novel approach of PET threshold identification with proof of application by collecting data from ten intersections located on four-lane intercity highways in the National Capital Region (NCR), India. Both crossing conflicts and right-turn related crash data (for the left-hand drive) are collected. Their correlations are thoroughly studied for each PET threshold using a quantitative technique considering all and individual vehicle categories. Finally, a qualitative analysis is done by ranking the sites based on cumulative PET and related crashes to verify the proposed quantitative technique. A PET threshold of 1?s is obtained from both the techniques which can be used to identify critical conflicts for unsignalized intersections located on four-lane intercity highways. The proposed methodology will serve as an alternative, faster and effective tool to evaluate the hazardousness of unsignalized intersections located on intercity highways under highly heterogeneous traffic condition. 相似文献

Poland has been and continues to be the leader of the transition economies of Eastern Europe. This study provides an in‐depth look at the ongoing economic, legal, and administrative policies of the Polish government in laying the ground‐work for a free‐market society. With the smaller business in mind, we first examine how the government of Poland moved decisively to lay the cornerstone for a private‐sector economy. Next, we demonstrate how Poland redirected its political and legal processes for long‐term global business. Finally, we describe what the U.S. government is doing to help Poland become a better trading partner and what this means to interested American firms. While there are many deep‐seated positive changes throughout Poland as it becomes a more significant global business player, there also are many challenges that must be understood by interested U.S. businesses if their investments in Poland are to be successful. © 2004 Wiley Periodicals, Inc. 相似文献

U.S. banking regulators have proposed a bifurcated system of capital regulation where the largest, internationally active
banking organizations would be subject to significantly more risk sensitive regulatory capital requirements than are currently
in place, while most others would remain subject to the current rules. The proposed new capital regime has the potential to
affect the competitive landscape among banking institutions, particularly in the area of residential mortgage lending. We
analyze the potential competitive effects of the proposed, bifurcated regulatory capital system on competition in the residential
mortgage market from the perspective of the theory of regulatory capital arbitrage. We then apply the theory and available
evidence to perform some benchmark calculations that suggest a significant, potential shift of market share and income to
the largest banking institutions in the mortgage market.
