We study interdependent risks in security, and shed light on the economic and policy implications of increasing security interdependence in presence of reactive attackers. We investigate the impact of potential public policy arrangements on the security of a group of interdependent organizations, namely, airports. Focusing on security expenditures and costs to society, as assessed by a social planner, to individual airports and to attackers, we first develop a game-theoretic framework, and derive explicit Nash equilibrium and socially optimal solutions in the airports network. We then conduct numerical experiments mirroring real-world cyber scenarios, to assess how a change in interdependence impact the airports' security expenditures, the overall expected costs to society, and the fairness of security financing. Our study provides insights on the economic and policy implications for the United States, Europe, and Asia. 相似文献

Many of the tasks encountered in image processing can be considered as problems in statistical inference. In particular, they fit naturally into a subjectivist Bayesis framework. In this paper, we describe the Bayesian approach to image analysis. Numerical examples are not included but references are given. It is argued that the Bayesian approach, still in its infancy, has considerable potential for future development. 相似文献

VII. Conclusion The number of immigrants now coming to the United States is proportionally only a fraction of the number that came in earlier
years, and there is nothing in those numbers to suggest a difficult absorption burden. Immigrants, both legal and illegal,
more than pay for the services they use with the taxes they pay, leaving a considerable net surplus that benefits American
citizens. Immigrants raise productivity and do not cause an observable amount of unemployment of citizens. Admitting far more
immigrants into the country than the law now allows would have positive effects on the incomes of citizens, and would enhance
the continuing vitality of the United States. 相似文献

Standard decision theoretic models disregard the phenomenon of interpersonal dependency of preferences. In this paper it is argued that interpersonal dependency of preferences is a serious challenge for standard utility theory. First we sketch the more philosophical aspects of the problem and then, using a simple, formal model for the two-person case, we show that interpersonal dependency of preferences generally results in indeterminacy of preferences (resp. of subjective utility). 相似文献

This study reviews recent sociological scholarship on empire and colonialism. The new 'imperial–colonial studies' in sociology is not a fully fledged subfield but an emerging space of inquiry that examines social forms, processes, and relations associated with imperialism and colonialism. This study sketches the main features of the new scholarship. It also situates the new sociological studies within a larger history of sociological inquiry and interdisciplinary context. Finally, it suggests that the future of sociology's new imperial–colonial studies lies not in 'sociologizing' the study of empire and colonialism but in deploying analyses of empire and colonialism to help critically reorient some of traditional sociology's limiting lenses and assumptions. 相似文献

Discrimination reduces the matching probability and output in the skill‐intensive differentiated‐product sector so that discrimination‐induced comparative advantage may overshadow technological comparative advantage in determining the pattern of trade. Trade liberalization generates a decrease in the skilled‐worker wage gap in the country that is an exporter of goods from the simple sector but increases it in the country that is a net exporter of differentiated products. Trade liberalization has an opposite effect on firms. In the country that is an exporter of simple goods, trade liberalization reduces the profits of the nondiscriminatory firms by more than those of the discriminatory firms. (JEL F16, F66, J71) 相似文献
