Even though a majority of the world's countries have proportional election systems, most of the quantitative methods are developed for majoritarian election systems. The purpose of this project is to develop quantitative methods for better understanding proportional elections systems.
Both from a theoretical and empirical perspective we know surprisingly little about how various factors affect politics in proportional election systems. This is because most of the theoretical models and empirical methods have been developed for majoritarian election systems. The purpose of this project is to develop empirical methods for answering some of the main questions for proportional elections systems. One of these questions is how party representation affects policy outcomes. For example, does increased representation for anti-immigration parties lead to more restrictive immigration policies? Other questions that this project aim to address is determinants of a political party’s bargaining position and how electoral reforms affect political outcomes. To answer these questions, municipal data from Sweden and Norway is used, together with data from national parliaments. Many of the studies within the project are collaboration with researchers from other countries.
