Most of the countries of South America experienced two notable institutional phenomena during the 1990s: the reform or rewriting of constitutions and the emergence of direct democracy mechanisms. This paper examines the latter process through a cross-national comparison. The introduction of direct democracy mechanisms is typically driven by traditionally excluded political interests. It takes two forms, both involving the failure of representative democratic institutions. In most cases, these traditionally excluded interests win control over the constitutional reform and rewriting process, although this is not a necessary condition for the emergence of direct democracy. Drawing illustrations from 12 cases of constitutional reform, this paper links arguments about direct democracy in the United States and Western Europe, institutional change, neopopulism, and the decline of the party system in Latin America.

Over the past decade, drug consumption has increased in Colombia and Mexico, countries traditionally concerned with drug production and trafficking. Governments and observers have associated this growth with spikes in violence. Drawing on drug consumption surveys and fieldwork in four cities, this study argues that contrary to this perception, there is no automatic connection between domestic drug markets and violence. Violence depends on whether large drug-trafficking organizations (DTOs) control low-level street dealers and on whether those DTOs have a market monopoly at the local level. When dealers are independent, violence might be sporadic, but when DTOs control dealers, violence can explode (given competition between DTOs) or implode (if one organization holds a monopoly). Control over dealers provides DTOs not only income but also informants and armed muscle. This article also shows that domestic drug markets are not new, and have grown incrementally in the past two decades.

Despite a strengthening of collective labor rights in Latin America over the last 15 years, most labor movements in the region have lost power because neither the content nor the enforcement mechanisms associated with the labor reforms fully took into consideration the challenges presented by economic restructuring. Reforms facilitating union formation did not strengthen unions but instead increased union fragmentation. Collective bargaining structures did not respond to the exigencies of international outsourcing; and the initial round of reforms in the 1990s did not contemplate the need to strengthen labor law enforcement mechanisms at a time when heightened international competition created a need for greater state vigilance of labor standards. Recent reforms or proposed reforms hold more promise for labor, but truly union-friendly labor relations regimes require deeper changes. A review of several Latin American cases is followed by a closer examination of Brazil and El Salvador.

Why do politicians in Mexico switch parties? The party-switching literature suggests that politicians generally switch parties for office-seeking or policy-seeking motives, whereas literature on the Mexican party system suggests that switching may be related to party system realignment during the democratic transition. Using data on party switching across the political careers of politicians who served as federal deputies between 1997 and 2009, this study argues that party switching in Mexico can primarily be explained by the office-seeking behavior of ambitious politicians. Only in rare instances do politicians switch parties because of policy disagreements, and party system realignment fails to explain a large number of party switches. This article also suggests that the ban on consecutive re-election encourages party switching; after every term in office, Mexican politicians have the opportunity to re-evaluate their party affiliation to continue their careers.

This article examines the internet's potential to democratize gender equality advocacy in Latin America. Based on field research in Argentina, Brazil, and Mexico, it challenges the assumption that the internet's horizontal organization and widespread dissemination inherently or inevitably lead to greater democratization. It advances two interrelated arguments. First, the internet's potential to foster democratic relations and effective strategies in civil society depends on the consciousness with which advocates adopt, share, and deploy the technology. Second, the internet is a critical resource for marginalized or socially suspect groups and subjects, providing a unique means to express and transmit often ostracized ideas and identities.

Literature on the Guatemalan Civil War has debated whether or not state violence was triggered by rebel activities. Did the government respond to each insurrection caused by the rebels, or did it blindly target regions where antigovernment antipathy and movements had historically prevailed? Because state violence was extensive during the civil war period, the dynamism of the war could have been the reason for its occurrence. Relying on the threat-response model of state violence, this article argues that human rights violations occurred when the government perceived a rebel threat that would have seriously degraded its capability in future counterinsurgencies. The article employs propensity score matching to address the problem of confounding in empirical analysis, and reveals that rebel attacks, particularly those targeting security apparatus and resulting in human injury, increased the likelihood of state violence in the Guatemalan Civil War.

The process of political transition in Mexico has fostered several institutional transformations in the political system. Such changes do not modify the system's design, but they do reactivate some basic institutions and forgotten powers that affect the operation of the political system as a whole. The state governors have undergone one of the most relevant transformations: they have gained more autonomy and have forged a new relationship with the federal executive. This essay analyzes the different actions governors have taken depending on their partisan origin. While the PAN governors focus on administrative and financial issues, the PRI governors have developed the most important political challenges to the president's authority.

This article examines the prospects for an interamerican “paradigm of democratic solidarity.” Although the region has seen genuine progress in the promotion and defense of democracy, a significant deficit in collective and national leadership hinders the consolidation of hemispheric prodemocracy activism. As illustrated by a number of recent cases, including the controversy over Peru's May 2000 election, these impediments are not only situational but structural. This article concludes with a discussion of ways to move beyond these problems and to buttress the democratic solidarity doctrine.

I am very pleased to start a dialogue with Samuel Valenzuela, although, because he reveals that he was one of the anonymous reviewers of my article, I have to point out that he was the only one out of five who disagreed with the editor’s decision to publish it. I hope that the dialogue might extend to other interested readers who can find my approach more helpful and challenging from the beginning.
