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 Child behavioral outcome is assessed by classmates for antisocial, prosocial, and withdrawn behavior and by parents and teachers for externalizing and internalizing problem behavior.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

Judicial deference to the other branches of government has become a common judicial technique in cases arising under the Human Rights Act. The author outlines the current approach of British courts in deciding when to defer, arguing that it is flawed and unprincipled. The author goes on to argue that a principled approach to deference is necessary, and offers examples of when and how courts should defer to the other branches of government when considering constitutional claims. 相似文献

The issue discussed is whether policies of imposing increasingly lengthy prison sentences on serious criminal offenders reduce crime. The empirical evidence for the deterrence and incapacitation effects of incarceration is first examined and found to be of limited help in answering the question whether lengthy prison sentences reduce crime. Conceptual and normative analysis of deterrence and incapacitation suggest that we have little reason to believe that the general use of lengthy prison terms produces more good than harm for society, especially if the burdens of and alternatives to such prison terms are taken into account. 相似文献
