An American specialist on the Soviet and Russian military-industrial complex examines the economic, social and political tensions within one of the most important, closed nuclear cities in Russia. Based on an intensive examination of the city's daily newspaper, not heretofore available in the West, the author explores the implications of the current situation for prospective nuclear accidents or proliferation.

The Conditional Nature of Political Risk: How Home Institutions Influence the Location of Foreign Direct Investment 下载免费PDF全文
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
