Public Choice theory has attempted to explain, "Why Government Grows?" by applying the logic of economics (individual choice, marginal decision making, the weighing of costs and benefits, the pursuit of profitable opportunities, etc.). Compare the political scientist's view of government and economic policymaking and the Public Choice conception of politicians, bureaucrats and special interest groups in the political process. Which do you consider to be more realistic for understanding the political process, and for thinking about economic policy issues? Why?
