The purposes of this essay are to describe how federal research and development policy has altered authority relationships and to suggest a new concept of legitimacy in accord with the changed conditions. Research and development (R and D) creates an indeterminate future. Thus, the politics of research and development incorporates an apparent contradiction : political leadership demands that jobs be done which require creative and unpredictable actions on the part of private organizations, while it also demands that contractors be held responsible for fulfilling goals efficiently, avoiding deleterious secondary consequences, and refraining from abuses of power. The paradox can be resolved by creating norms of responsibility that allow for judgments on how a job is done rather than what is to be done. New institutions for technological assessment to check on unintended consequences of projects and citizen review boards to estimate the quality of life engendered by projects may provide such norms of responsibility. 相似文献

Central governments face compliance problems when they rely on local governments to implement policy. In authoritarian political systems, these challenges are pronounced because local governments do not face citizens at the polls. In a national‐scale, randomized field experiment in China, we test whether a public, non‐governmental rating of municipal governments' compliance with central mandates to disclose information about the management of pollution increased compliance. We find significant and positive treatment effects on compliance after only one year that persist with reinforcement into a second post‐treatment year. The public rating appears to decrease the costs of monitoring compliance for the central government without increasing public and media attention to pollution, highlighting when this mode of governance is likely to emerge. These results reveal important roles that nonstate actors can play in enhancing the accountability of local governments in authoritarian political systems. 相似文献

The impact of institutions on the economic vote stands as a well‐established proposition for the advanced democracies of Europe. We know less, however, regarding the institutional effects on the economic vote in the developing democracies of Latin America. Carrying out an analysis of presidential elections in 18 Latin American countries, we offer evidence that the usual Eurocentric conceptualization of the clarity of responsibility is not ideal for understanding the economic vote in this region. There does exist a powerful effect of institutions on the economic vote within Latin American democracies, but one uniquely associated with its presidential regimes and dynamic party systems. Rules for these elections—such as concurrence, term limits, and second‐round voting—suggest that we should reconceptualize the notion of the clarity of responsibility in Latin America, focusing more on individuals in power and their constraints, and less on the political parties from which they hail. 相似文献
