Scholars continue to debate whether economic development affects regime type. This article argues that a clear relationship exists between development and the electoral component of democracy, but not – or at least less so – between development and other components of broader understandings of democracy. This is so because development enhances the power resources of citizens and elections provide a focal point for collective action. The theory is tested with two new datasets – Varieties of Democracy and Lexical Index of Electoral Democracy – that allow us to disaggregate the concept of democracy into meso- and micro-level indicators. Results of these tests corroborate the theory: only election-centred indicators are robustly associated with economic development. This may help to account for apparent inconsistencies across extant studies and shed light on the mechanisms at work in a much-studied relationship. Further analysis shows that development affects electoral democracy by reducing electoral fraud, election violence and vote buying.  相似文献

In 1961 the US Central Intelligence Agency master‐minded a sea‐borne invasion by Cuban exiles aimed at overthrowing the regime headed by Fidel Castro. With minimal logistical support from the USA the attempted counter‐coup launched at the Bay of Pigs was an unqualified disaster: a ‘perfect failure’, in the words of an authoritative contemporary. This essay locates the fiasco in the longer history of US–Cuban relations, concentrating on the Cold War years, the history of US political intervention and subversion in Latin America, and the dictatorship of Fulgencio Batista and the rise of Castro himself—both men offering different models of Latin American caudillismo (the power and cult of military strongmen). The essay concludes with an analysis of Cuba as an issue in US domestic politics and the impact of the Bay of Pigs in consolidating the Cuban revolution and setting the framework for the Cuban Missile Crisis of October 1962.  相似文献

Research on candidate competition has focused on how much context matters in emergence decisions and election outcomes. If a candidate has previously held elected office, one additional consideration that may influence entry decisions is the relative degree of overlap between the candidate's current constituency and the “new” set of voters she is seeking to represent. Using GIS software, we derive a measure of the challenger's personal vote by focusing on constituency congruency between state legislative and congressional districts. Results suggest state legislators are more likely to run for a seat in the U.S. House if constituency congruency is relatively high.  相似文献

Explaining why crime is spatially concentrated has been a central theme of much criminological research. Although various theories focus on neighborhood social processes, environmental criminology asserts that the physical environment plays a central role by shaping people's activity patterns and the opportunities for crime. Here, we test theoretical expectations regarding the role of the road network in shaping the spatial distribution of crime and, in contrast to prior research, disentangle how it might influence offender awareness of criminal opportunities and the supply of ambient guardianship. With a mixed logit (discrete choice) model, we use data regarding (N = 459) residential burglaries (for the first time) to model offender spatial decision‐making at the street segment level. Novel graph theory metrics are developed to estimate offender awareness of street segments and to estimate levels of ambient guardianship, distinguishing between local and nonlocal guardianship. As predicted by crime pattern theory, novel metrics concerning offender familiarity and effort were significant predictors of residential burglary location choices. And, in line with Newman's (1972) concept of defensible space, nonlocal (local) pedestrian traffic was found to be associated with an increase (decrease) in burglary risk. Our findings also demonstrate that “taste” preferences vary across offenders, which presents a challenge for future research to explain.  相似文献
