An End to the Fourth Wave of Terrorism?

It is widely believed that the current wave of religiously inspired terrorism will persist for the foreseeable future. Is this necessarily the case? This article asserts that this present wave may be cresting, much like previous waves in the modern history of terrorist violence. Further, the article goes on to forecast not an end to terrorism in general, but the likely emergence of still new manifestations of terrorist violence.     

掠夺性定价的经济学及法律分析——美国和欧盟的经验与趋势

掠夺性定价一般表现为企业为排挤、制约竞争对手或阻碍竞争对手进入市场而在相当长的一段时期内故意将价格设置于其成本之下。其目的是为将竞争对手逐出市场并随后设定高于竞争水平的价格,以收回前期降价的损失。《中华人民共和国反垄断法》以及其他相关的法律法规都包含了禁止掠夺性定价的规定。然而,对于掠夺性定价中的一些具体问题还没有相应的法制规章提供指引和解读,再加上此类案件法院判决的先例在中国现阶段还属少见,因此,本文将详细讲解近年来美国和欧盟的经济学家、反垄断机构以及法院对此类经典案件(如Wanadoo案等)的审理分析经验与趋势,以供借鉴。     

A deadly return. Tuberculosis

Fueled by poverty, homelessness and AIDS, a disease we almost wiped out is back in a dangerous new form. Its resurgence is neither fluke nor mystery, but a tragic social failure.     

Natalist Policies in the United States

This retrospective reviews the policies that affect the fertility of American women, both policies designed to alter fertility intentionally as well as those that change childbearing unintentionally. Becker's seminal work on the economics of fertility serves as the theoretical foundation for this literature. After describing Becker's economic model, we review the empirical literature on fertility responses to social welfare policies, tax policies, the mandated health care coverage of infertility treatments, abortion policies, and government‐sponsored family planning services. We also address several Supreme Court cases that have played an important role in the interpretation of these policies. Where relevant, this retrospective describes the distributional effects of these natalist policies. We also discuss the limitations of this literature and identify important gaps. Unlike most developed countries that have created strategies to increase fertility to support their ageing population, the United States spends considerably less time and thought on this issue. Our reading of the literature suggests that we have many public policies that have affected and continue to influence the fertility choices made by families in the United States and that this is a topical area that deserves more attention in policy debates.
