David Easton and the Invisible Hand

This article demonstrates that, despite David Easton's assertions to the contrary, economic conceptions play a crucial role in his version of systems theory. A comparison between Easton's model of the political system and the classical economic model of Adam Smith reveals that they share the notions of system, scarcity, allocation, competition, maximization, self-regulation, homeostatic equilibrium, goal-seeking, and feedback. This comparison of Smith and Easton not only illuminates the logical and unacknowledged historical foundations of Easton's framework, it also clarifies some common misconceptions concerning systems analysis (e.g., the idea that it is static or that it is tautological) and underscores a number of important limitations on the utility of Easton's model as a tool for political analysis (i.e., the model requires a given pattern of behavior, a particular cultural environment and a specifiable institutional complex for its operation).
