Research on executive‐legislative relations in Latin America has focused on the impact of minority presidents and multiparty legislatures on legislative productivity. But an additional deadlock scenario, the blocking of a majority president by a minority through filibustering, has been understudied. This article analyzes filibustering in Costa Rica and explains the legislative paralysis in the wake of the nation's transition to a multiparty system in 2002. Legislative paralysis is seen as a product of the interaction between increased legislative fragmentation and polarization and the legislature's preexisting rules of procedure, which enable legislators easily to block bills they oppose, even when those bills are supported by supermajorities. This argument is tested through a comparison of major economic reforms in the 2000s to the reforms tackled in the 1990s. The role of filibustering, well acknowledged in U.S. politics, should also be studied in comparative politics.  相似文献

This article seeks to explain why electoral support for the Venezuelan opposition has increased substantially, using Venezuelan public opinion survey data from LAPOP and an opt‐in sample collected through the online vote advice application Brújula Presidencial Venezuela. It analyzes why Venezuelans who had either voted for Chávez or abstained in 2006 defected and started to support the opposition in subsequent elections. It proposes several reasons: negative voter evaluations of the economy, concern for public safety, and dissatisfaction with Venezuelan democracy. While the finding that negative policy evaluations boost support for the opposition aligns with theoretical expectations, this study finds a strong relationship between having different evaluations of the quality of democracy and supporting Chávez, which shows that the advocacy of two competing visions of democracy by the incumbent and the opposition also affects voting patterns in Venezuela.  相似文献

Agroecology has played a key role in helping Cuba survive the crisis caused by the collapse of the socialist bloc in Europe and the tightening of the US trade embargo. Cuban peasants have been able to boost food production without scarce and expensive imported agricultural chemicals by first substituting more ecological inputs for the no longer available imports, and then by making a transition to more agroecologically integrated and diverse farming systems. This was possible not so much because appropriate alternatives were made available, but rather because of the Campesino-a-Campesino (CAC) social process methodology that the National Association of Small Farmers (ANAP) used to build a grassroots agroecology movement. This paper was produced in a ‘self-study’ process spearheaded by ANAP and La Via Campesina, the international agrarian movement of which ANAP is a member. In it we document and analyze the history of the Campesino-to-Campesino Agroecology Movement (MACAC), and the significantly increased contribution of peasants to national food production in Cuba that was brought about, at least in part, due to this movement. Our key findings are (i) the spread of agroecology was rapid and successful largely due to the social process methodology and social movement dynamics, (ii) farming practices evolved over time and contributed to significantly increased relative and absolute production by the peasant sector, and (iii) those practices resulted in additional benefits including resilience to climate change.  相似文献

The regulatory regionalism approach has increasingly claimed that a new mode of regional governance is emerging globally. Regional policy regimes, developed in broad social and economic territorial areas, affect the internal transformation of the state. The authors plan to provide comprehensive empirical evidence about the emergence of worldwide regulatory regionalism by identifying how regulatory agencies have diffused very successfully within the regional level in recent decades. The paper aims to identify, using an original methodological design, the ways in which such diffusion of agencies occurred, as this may have theoretical relevance for the study of regulatory regionalism. The authors' hypothesis suggests that transnational political interactions in each regional cluster triggered agency diffusion, contributing to the development of the regulatory state within the countries of each region. To test this hypothesis, the authors employed a data set of regulatory agencies including the OECD (Organisation for Economic Co-operation and Development), and most Asian and Latin American countries (+59) from 1950 to 2007, for 15 sectors related to finance, risks, utility and competition. Bayesian data analysis was used to estimate the parameters of interest.  相似文献

International residential tourism is a recent phenomenon in the Andean area. However, in places where it has been established, rapid changes in social and economic structures have occurred. The Municipality of Cotacachi (Northern Ecuador) is paradigmatic. Having become a destination for American retirees, residential tourism has generated a sharp increase in the price of rural land and has decelerated a land market that once allowed young farmers to continue agricultural activities. Residential tourism has promoted land exchange value while sacrificing use value, threatening peasant reproduction mechanisms.  相似文献
