The main theories of the thriving field of study of public policies have been formulated at institutions of developed countries, mostly by the American academy, based on the particular conditions of policy-making processes of their own country. However, its heuristic premises are considered, initially, as universal and are used extensively in teaching and academic studies around the world. This paper examines the complexities derived from the application of such predominant theoretical approaches to the study and teaching of public policies that are implemented in Latin American countries. Based on an extensive use of specialized literature, 10 public policy variables are identified and organized into two dimensions, one institutional and the other procedural. It is argued that the values of these variables in the countries of this region differ significantly from those observed in the United States, which reveals the explanatory shortcomings of those approaches to account for the particular modalities of public policymaking in these countries.
