What determines whether countries' institutions attract or deter investment? Although existing theories predict that multinational enterprises (MNEs) avoid locations where institutions cannot constrain public and private actors' opportunistic behavior, we argue host institutions' attractiveness depends on firms' home environment. Home country institutions shape firms' practices and capabilities, thus helping to determine the environments that firms are best prepared to face abroad. We test our predictions using multiple data sets at different levels of analysis: firm‐level data on MNEs' foreign subsidiaries, data on bilateral foreign direct investment (FDI) positions, and longitudinal data on bilateral FDI flows. We find that states with independent judiciaries are particularly attractive to investment from countries also possessing independent courts. Similarly, countries with low judicial independence disproportionately send FDI to countries lacking independent judiciaries. These findings' implications challenge conventional wisdom: “Good” institutions may not attract all investors, and “bad” institutions may not always deter, as current research suggests.  相似文献

Youth violence in America has grown to insurmountable levels. Homicide is now the third leading cause of death for youth ages 5–14, the second leading cause of death for those ages 15–24 and the number one cause of death among black males ages 15–34. With increased levels of violence and senseless killings across the nation, there is a need to explore behavioral and environmental causes of high risk behavior and various types of interventions to decrease antisocial behavior. Violence prevention should be approached comprehensively from a myriad of approaches and levels of prevention and intervention that should infiltrate individuals, homes, schools, communities and systems.

Numerous types of theories are being designed, implemented and evaluated to decrease and prevent unhealthy behaviors. While there is a need to continue to refine intervention and containment strategies, a preventative approach to addressing root causes of antisocial behaviors needs to be considered as we comprehensively look at interventions for violence prevention. The purpose of this article is to add to the body of research a theory, the Priority/ Consequence model, which depicts interrelated dynamic behavioral and societal variables that can influence, positively or negatively, attitudes, values and beliefs that establish prioritized behaviors that produce consequences.  相似文献

This article provides the first detailed study of the origins of staggered Senate terms, which typically have been interpreted as part of the framers’ intent to create an insulated, stable, and conservative Senate. I draw upon three sources of evidence—the meaning and application of “rotation” in revolutionary America, the deliberations and decisions at the Constitutional Convention, and the arguments during Ratification—to show that the origins of and intentions behind staggered terms offer little support for the dominant interpretation. Instead, staggered terms, a mechanism to promote “rotation” or turnover of membership, were added to the Constitution as a compromise to offset, not augment, the Senate's longer terms by exposing a legislative chamber with long individual tenure to more frequent electoral influence and change.  相似文献
