This dissertation addresses the effect of informality on three key dimensions: social policypreferences, partisan attachments, and citizen-politician linkages. Many Latin Americanlabor markets have large informal sectors where workers are not covered by formal laborarrangements and earn meager wages, as well as truncated social security systems thattarget benefits to the well-off at the expense of the poor.I first analyze how economic informality conditions voters preferences regarding the redistributive role of the state (Chapter 3). I examine the effect of labor informality on individual preferences over contribution-based programs (such as social security and public health insurance) and means-tested programs (such as CCTs). The analysis of micro-level data for both Latin America and Mexico suggests that, counterintuitively, voters in the informal sector are no more likely to support increased spending in social security and welfare institutions. On the contrary, labor market outsiders tend to favor only social programs with no eligibility requirements.In the second part of the project, I study patterns of party identication among citizensin the informal sector (Chapter 4). I argue that the low utility derived from social policiesand the obstacles to class identity formation contribute to depress partisan attachments.The findings indicate that economic informality weakens ideological attachments betweenvoters and political parties. Results also show that outsiders trust less in political parties.Finally, I analyze how economic informality conditions linkages between citizens andpoliticians (Chapter 5). I theorize that given the characteristics of the members in theinformal sector, political parties will have incentives to approach them usingclientelistic offers and vote-buying strategies. I find that voters in the informal sector are particularly sensitive to some types of clientelistic offers. Furthermore, labor market outsiders seem to be more likely to switch their vote toward candidates offering private benefits.
