Economic openness, policy uncertainty, and the dynamics of government support

Does globalization affect popular support for national governments? This article contends that exposure to the world economy obscures mass-elite linkages in developed democracies. Market interdependence, I argue, sends a signal to citizens that the policymaking environment has become more complex. As a consequence, publics are less certain of how to evaluate policymaker performance when exposure to the world economy increases. Informed by research on the role of uncertainty in public evaluations, I test this proposition by modeling the volatility of aggregate government popularity as a function of economic openness in four advanced industrial democracies. Results show that globalization increases the volatility-and, hence, the uncertainty-of public assessments of government performance. The implications for the political economy of advanced capitalist democracies and for models of collective public opinion are discussed. (C) 2007 Elsevier Ltd. All rights reserved.
