The article by Theodore J. Lowi, titled "Four Systems of Policy, Politics, and Choice," published in *Public Administration Review* in 1972, explores the relationship between policy, politics, and choice in American governance. Lowi argues that the traditional political science vocabulary is insufficient for understanding the complexities of government functions and policies. He proposes a taxonomy of policies to better analyze and predict political behavior. Lowi identifies four types of policies: distributive, regulatory, redistributive, and constituent. Each type of policy has distinct characteristics and implications for politics. For example, distributive policies, which focus on sharing resources, often involve strong congressional dominance, while regulatory policies, which aim to control behavior, tend to be more influenced by the executive branch. The article also examines the impact of these policy types on presidential power. Strong Presidents, such as Franklin D. Roosevelt, can exert significant influence, but their effectiveness is shaped by the policy environment. Roosevelt's New Deal policies, for instance, transformed politics by introducing a multiplicity of regulatory and redistributive policies, which in turn influenced the political landscape. Lowi's analysis is supported by case studies of various policy areas, including the Rivers and Harbors Act, the Airports Aid Act, and the Social Security Act. These cases illustrate the varying degrees of presidential and congressional influence, and the importance of understanding the context in which policies are formulated. The article concludes with implications for policy choice and prediction. It suggests that a better understanding of policy types can help political scientists develop more accurate models of political behavior and guide policy decisions. The framework proposed by Lowi aims to provide a systematic approach to analyzing and predicting political outcomes, emphasizing the importance of context and the interplay between different policy types.The article by Theodore J.
