In social media, acceptance equals propagation, as the act of sharing posts exposes a larger number of users to the preferred content of their peers. As users select or discard content, they collectively highlight facets of events or issues as to promote a particular interpretation. In this article we take on the challenge of analyzing how social media users frame political events by selectively sharing content that is cognitively congruent with their beliefs. We exemplify the proposed theory with a study of recent protest events in Argentina.

Recent experiences with market reform in democratizing countries have generated interest in how structural and institutional factors contribute to the political viability of the reform process. This article thus examines the electoral dynamics of market reform in Argentina between 1989 and 1995, and provides insights into the way that economic differentiation and the territorial distribution of political resources can shape

Politicians can bene…t by ensuring that public sector positions requiring political services are occupied by partisans. We study a model in which this political screening is achieved by varying the amount of required political services and associated com-pensation in otherwise similar positions. Past vote shares reect the population share of partisans, and we predict a U-shaped relationship between an employee's current salary and the incumbent politician's vote share at the time of hiring. We test for this e¤ect using individual data from a large national income survey from Argentina, a country with widespread political patronage. The results are consistent with the model, showing that political conditions at the time of hiring have long-lasting e¤ects on public employees'wages. seminar participants at the University of Houston, Rice University, SEA 2009, MIEDC 2010, APET 2011, and the Institute of Economics (Hungarian Academy of Sciences) for comments and suggestions.

This paper presents the first study on the impact of alternative electronic voting technologies on election outcomes in multi-party elections, analyzing data from a large-scale voting experiment conducted in the 2005 congressional election in Buenos Aires, Argentina. In order to control for in-sample differences between treatment groups, we use a smooth coefficient vector generalized model to estimate the effect of different e-voting devices on the support for the parties competing in the election. Our empirical approach allows improving covariate balance while mitigating model-dependent inference, providing a useful strategy for causal inference in research designs combining categorical treatments and multivariate outcomes. Our substantive findings indicate that voters are extremely receptive to information effects embedded in different voting technologies and associated ballot designs, and that particular voting devices have a significant impact on voter choice, systematically fav...

Using data from an e-voting experiment conducted in the 2005 Congressional Election in Argentina, we estimate the effect of different e-voting technologies on the likelihood that citizens cast their vote for different parties for the National Congress and the Legislature of Buenos Aires. Our results indicate that voters are extremely receptive to the information cues provided by the different voting technologies and associated ballot designs, and that particular voting devices have a significant impact on voter choice, systematically favouring some parties to the detriment of others. We conclude that the choice of alternative electronic voting devices might have considerable effect on electoral outcomes in multi-party electoral systems.
