14080. LEGISLATIVE POLITICS. Drawing on the work of political science theorists in the field of legislative decision-making, this paper examines three analytical models or approaches used to study and explain legislative policymaking: 1) principal-agent; 2) rational expectations (with reference to the rational choice model as its precursor); and 3) coalition analysis. The investigation considers the pros and cons of each of the three appraches and looks at the kinds of problems in legislative policymaking for which each of the models has most often been used, considering the applicability of the other two models to these types of problems. A concluding section makes a summary comparison of the three models. 18 pages, 34 footnotes, 13 bibliographic sources.
