Essays in Political Economy

Sammanfattning: This thesis consists of an introduction and three stand-alone essays. In the introduction I discuss the commonalities between the three essays. Essay I charts the the main political cleavages among 59 Swedish unions and business organizations. The main conclusion is that there appear to exist two economic sources of political cleavage: The traded versus the nontraded divide and the labor versus capital divide. Essay II suggests a political rationale for why strikes have been more common in those OECD countries where the legislature is elected in single member districts (e.g. France, Great Britain) than where it was elected by proportional representation (e.g. Sweden, Netherlands). In Essay III I present a theoretical model of political support for different types of labor market regulations. From it I recover two implications: Support for industrial relations legislation that enables unions to bid up wages should be inversely related to the economy's openness, while support for employment protection legislation should be positively related to the size of the unionized sector. Empirical evidence from a cross-section of 70 countries match my theoretical priors.
