Explaining Lawmaking in the United States, 1877–1994
This chapter turns to lawmaking and shows that legislative productivity varies considerably by policy issue area. Specifically, it illustrates that the key determinants of legislative productivity differ by policy substance. It also provides empirical evidence that questions the benefits of pooling legislation when such aggregation often obscures empirical findings related to understanding the mechanisms of lawmaking. The chapter aims to determine whether pooling policies (using an overall aggregate measure of all legislation) is potentially inappropriate. This multivariate analysis draws on data using two different thresholds of significance. The highest threshold uses the top 500 enactments; while the second threshold uses the top 3,500 enactments. This threshold captures landmarks for very important legislation.
