Risk perceptions are important to the policy process because they inform individuals’ preferences for government management of hazards that affect personal safety, public health, or ecological conditions. Studies of risk in the policy process have often focused on explicating the determinants of risk perceptions for highly salient, high consequence hazards (e.g., nuclear energy). We argue that it is useful to also study more routinely experienced hazards; doing so shows the relevance of risk perceptions in individuals’ daily lives. Our investigation focuses on the impact perceived risk has on citizens’ preferences over hazard management policies (as distinct from identifying risk perception determinants per se). We use a recursive structural equation model to analyze public opinion data measuring attitudes in three distinct issue domains: air pollution, crime, and hazardous waste storage and disposal. We find that citizens utilize perceived risk rationally: greater perceived risk generally produces support for more proactive government to manage potential hazards. This perceived risk–policy response relationship generally holds even though the policy options respondents were asked to consider entailed nontrivial costs to the public. The exception seems to be when individuals know less about the substantive issue domain. 相似文献

While state governments have enjoyed greater control over regulating local telephone service providers since 1984, movement toward efficiency-based policy reform (e.g., adoption of competitive markets) has proceeded slowly. We investigate this pattern by addressing how the degree of policy discretion held by state public utility commissions (PUCs) affects reform of local telephone exchange regulation. Using precise measures of both PUC discretion and state policy changes over time, we find that states with "stronger" PUCs (more policymaking authority) are significantly more likely to move toward efficiency-based policy regimes and away from traditional rate-of-return regimes. Greater PUC discretion systematically related to state adoption of efficiency-based reforms over time suggests that regulators are using updated information about policy impacts to inform their policymaking activities. Our findings contradict a common presumption that regulatory bureaucracies are simply motivated by a desire to increase their control over policymaking. Instead, state PUCs are a key source of telecommunications policy reform in the states. 相似文献

From 'industrial districts' to 'knowledge clusters': a model of knowledge dissemination and competitive advantage in industrial agglomerations 总被引:6,自引:0,他引:6

This paper integrates knowledge-based theories of the firm withgeograph-ical studies of industrial agglomeration to producea model that helps explain the competitive advantages enjoyedby proximate firms located in geographical clusters. We proposea hierarchy of specialized knowledge stocks at both firm andcluster levels and suggest that the comparative advantage conferredby knowledge resources at each level is protected, in part,by asymmetries in knowledge flows from level to level. The paperargues that codified component knowledge is more easily spreadthan firm-specific architectural knowledge. Nevertheless, overtime, agglomerations may develop a cluster-specific form ofarchitectural knowledge that facilitates the rapid disseminationof knowledge throughout the cluster by increasing the learningcapacity of proximate firms and thereby conferring cluster-specificcompetitive advantages. 相似文献
