ABSTRACT. We reexamine the price structures and their welfare implications in three pricing regimes (mill, uniform and discriminatory) for a monopoly. We show that spatial price discrimination could provide the highest social welfare and, when consumers tastes are heterogeneous enough, also the highest consumer surplus. The superiority of spatial price discrimination is partially due to the larger output produced and partially due to differential treatment for consumers with heterogeneous tastes. 相似文献

This paper examines the diversity of uses of Adam Smith’s ideas in nineteenth-century American debates about the tariff. Legislative debates about American trade policy ran almost uninterrupted from the 1820s to the end of the century; as a result, they provide an abundance of examples of the ways in which legislators marshaled economic ideas to shape political discourse and influence policy. Smith’s causal ideas about free trade and its effects were referenced in policymaking, and Smith’s intellectual authority was often invoked as a legitimating device for partisan ideology. These uses, I argue, contributed to the sloganizing of Smith as the ‘apostle of free trade’ and his enduring popularity as a political icon in American politics. 相似文献

由于多视角影像三维重建具有数据采集方便灵活、硬件成本低、操作简单、自动化程度高的特点,因此,选用多视角影像三维重建技术对张家界市博物馆明代铜佛像进行三维建模。通过描述佛像立面与空心底部的影像采集,再应用Agisoft PhotoScan软件进行三维重建的过程;从控制点的三维坐标与误差数值、模型成像与影像图的误差分析,得出佛像三维模型的精度误差微小的结论,证明该技术具有操作简单、模型成像清晰的特点。与三维激光扫描技术相比较,多视角影像三维重建技术具有成本费用低、工作流程高效简捷的优势,更适合在文物工作中推广运用。 相似文献

Sir William Chambers was one of the most important English architects in the eighteenth-century, but both in his day and later his international recognition was closely connected with his admiration for and promotion of Chinese art, particularly Chinese landscaping. Between 1757 and 1773, Chambers published three treatises praising the ingenious mixture of nature and art in a Chinese pleasure ground, criticizing the then influential English gardener Lancelot (Capability) Brown, and trying to goad English garden design into the direction of China. He did not achieve his purposes mainly because he mixed what he knew as genuine about the Chinese gardening art with what he fantasized about it. While recent scholarship has focused on his fantasy, this article examines what Chambers knew or imagined about Chinese landscaping, what he and his detractors were for and against, and how the fiasco of his 1772 and 1773 treatises, which he brought upon himself, nevertheless helped to usher in a new phase in the English reception of Chinese landscaping ideas. 相似文献

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity. 相似文献
