Dynamics of Representation: The Case of US Spending on Defence

The representation of public preferences in public policy is fundamental to most conceptions of democracy. If representation is effectively undertaken, we would expect to find a correspondence between public preferences for policy and policy itself. If representation is dynamic, policy makers should respond to changes in preferences over time. The integrity of the representational connection, however, rests fundamentally on the expectation that the public actually notices and responds to policy decisions. Such a public would adjust its preferences for ‘more’ or ‘less’ policy in response to what policy makers actually do, much like a thermostat. Despite its apparent importance, there is little research that systematically addresses this feedback of policy on preferences over time. Quite simply, we do not know whether the public adjusts its preferences for policy in response to what policy makers do. By implication, we do not fully understand the dynamics of representation. This research begins to address these issues and focuses on the relationships between public preferences and policy in a single, salient domain.
