With remarkable success, Latin Americans have sought to impose their free trade policy agenda on a very reluctant and internally fractious United States. They have an ally in President George W. Bush, whose senior appointments notably support hemispheric trade integration even as political pressures sometimes have yielded protectionist outcomes. Bush's trade negotiator, Robert Zoellick, pursues a doctrine of competitive liberalization while accepting some linkage between trade and social and political goals. In negotiating the Free Trade Area of the Americas (FTAA), the administration will have to balance many domestic pressures without alienating Latin America. Ultimately, FTAA ratification will signal a new Western Hemisphere economic-security alliance for the twenty-first century. 相似文献

Traditional views of dualistic development emphasize differences in behavior between the traditional and modern sectors. In
this article it is argued that a better distinction concerns market networks. A traditional sector is characterized by a lack
of market integration. Such market integration can be achieved only through dramatic growth of a domestic market for basic
agricultural goods. This will most likely involve the simultaneous protection and taxation of the agricultural sector. Thus,
protectionism was an appropriate strategy of development, but most nations protected the wrong sector (industry) at the wrong
time in the process of long-run development.

This paper analyzes the competitive significance of advance price announcements. In the model, advance price announcements are used by firms to communicate private information on demand or cost. By so sharing the information, the firms are able to set their prices at more profitable levels. When the advance price announcements resolve demand uncertainty, profits rise and consumer surplus falls. Interestingly, when the advance price announcements resolve cost uncertainty, both profits and consumer welfare rise. Finally, we examine U.S. antitrust policy regarding price announcements. 相似文献

This study tests a model of the effects on child behavioral outcome of the child's exposure to partner violence and child abuse, in children who have experienced the two forms of victimization either separately or together. Recognizing that family contextual factors play an important role in influencing child outcome, an ecological model is proposed that designates family stress as the principal exogenous factor, with effects on child outcome mediated through caretaker distress, partner violence, and child abuse. The sample consists of 100 confirmed cases of physically abused New York City schoolchildren, ages 9 to 12 years, and their families, and 100 nonmaltreated classmates, matched for gender, age, and, as closely as possible, for race, ethnicity, and socioeconomic status, and their families. Child behavioral outcome is assessed by classmates for antisocial, prosocial, and withdrawn behavior and by parents and teachers for externalizing and internalizing problem behavior. Results are generally consistent with the hypothesis that partner violence and caretaker distress, both associated with family stress, increase the risk for child abuse and thereby raise the child's risk for poor outcome. Implications of differences among raters for the model's applicability, and implications of the results for clinical intervention, are discussed. 相似文献
