This article is an examination of the candidate preferences of 2008 superdelegates and of their role in determining the eventual Democratic nominee. Multivariate analysis suggests that female superdelegates were less likely to support Obama than were men; African-Americans, in contrast, were more likely to support his candidacy. A higher percentage of the popular vote received by Obama in the p…
International institutions lack the independent ability to punish non-compliance, but states sustain cooperation because they can target one another for punishment. In contrast, international criminal courts and tribunals (ICTs) can enforce rulings once suspects are in custody, but they lack the independent power of capture, leaving them unable to punish alleged criminals and therefore deter cr…
We report the results of a trust survey and public goods experiment conducted with high school students in rural Thailand and Cambodia that together help clarify the dynamics at work in sustaining economic cooperation within these two third-world communities. We find that standard survey measures of trust employed by the World Values Survey, which form the basis of most macro-empirical investig…
We provide an analysis of a power-maximising model for dictatorial behaviour. In the model, the dictator’s revenues depend on the exports of a single crop. Using export earnings the dictator buys loyalty from the producers of the export crop by setting the domestic producer price. Revenues resulting from the difference between the international and the domestic price of the crop are used to fin…
The ‘mean voter theorem’ implies that candidates should choose identical policy positions in a two-candidate race if voting is probabilistic. This result is in fact an artifact of the assumption that the candidates maximize expected vote share or probability of win, which is not true for many real-world elections. In this paper I analyze a probabilistic voting model in which the candidates have…
Why would a generic parliament have committees with minority party members? If the majority party considers minority party committee members a burden, then it could choose to exclude minority party members entirely from the committee system. This, however, has rarely happened in history. In this paper, I provide an informational rationale for the bipartisan committee system through a simple sig…
The Groseclose and Snyder (1996) model is one of the best-known models of vote buying in legislatures. Although the logic of the model is compelling, it is not clear that its key propositions, derived in a continuous set-up, hold in finite legislatures. This is an important issue because many real-world legislatures are small and should be modeled as finite in order to make predictions on coali…
Followers of law, politics and business commonly relate stories of individuals who appear to predict an expected performance level below what they believe themselves to be capable of. The standard explanation for such rhetoric is that it hedges against the negative consequences of unanticipated failures and takes advantage of unexpected successes. Although the strategy appears highly attractive…
There is an increased focus in comparative politics and international relations on how choices of governments are dependent on choices made by other governments. The authors argue that although the relationship between policy choices across countries is often labeled as either diffusion or competition, in many cases the theoretical mechanisms underpinning these labels are unclear. In this artic…
One of the long-standing criticisms of cross-sectional survey data is that they provide only a contextually driven “snapshot” of attitudes. These attitudes are, the “snapshot critique” contends, highly fragile—subject to significant fluctuation based on events that arise domestically and globally. Although it makes sense that a major event can alter the percentage of people who respond to a giv…
This study presents a new explanation to a puzzle regarding the reluctance of the Japan Socialist Party (JSP) to moderate its hard-liner Marxist platform. The author does so by focusing on the preferences and strategies of individual JSP members, in contrast to previous studies that treat the party as a unitary actor. The author shows that Japan’s electoral system created a unique environment i…
Terrorists attack civilians to coerce their governments into making political concessions. Does this strategy work? To empirically assess the effectiveness of terrorism, the author exploits variation in the target selection of 125 violent substate campaigns. The results show that terrorist campaigns against civilian targets are significantly less effective than guerrilla campaigns against milit…
Lustration is alternately theorized and anecdotally alleged to either undermine or contribute to the democratic transitions in Central and Eastern Europe (CEE) by supporting or undermining trust in public institutions, and by extension trust in national government. Using quantitative data on nine countries in CEE, this study examines the impact of lustration and transitional justice measures on…
Studies evaluating the effects of territorial state organization on the performance of democratic political systems produce ambiguous results. The authors argue that research so far has suffered from insufficiently conceptualizing federalism and decentralization as two distinct dimensions. This article makes use of the advantages of a nested design and detects micro-level causal mechanisms unde…
In this article the authors investigate the relationship between concerns about crime and concerns about immigration. Panel survey data from Germany allow the authors to examine people’s views about immigration as they develop over time, showing that consternation about crime is a significant predictor of anxiety over immigration. Moreover, it has a greater substantive impact than other explana…
Sustained mass media campaigns have been recommended to stem the tobacco epidemic in the United States. Propensity score matching (PSM) was used to estimate the effect of awareness of a national smoking cessation media campaign (EX®) on quit attempts and cessation-related cognition. Participants were 4,067 smokers and recent quitters aged 18–49 in targeted U.S. media markets. Controlling for po…
Background: A small but growing body of research evidence suggests that place-based police interventions generate significant crime control gains. While place-based policing strategies have been adopted by a majority of U.S. police departments, very few agencies make a priori commitments to rigorous evaluations. Objective: Recent methodological developments were applied to conduct a rigorous ex…
Covariate adjustment can increase the precision of estimates by removing unexplained variance from the error in randomized experiments, although chance covariate imbalance tends to counteract the improvement in precision. The author develops an easy measure to examine chance covariate imbalance in randomization by standardizing the average covariate difference between the treatment and control …
Background: In recent years, several states have created mandatory prison-diversion programs for felony drug possessors. These programs have both individual-level goals of reducing recidivism rates and system-level goals of reducing prison populations. Objective: This study examines the individual level and system level impact of Kansas’ Senate Bill 123 (SB 123), which created mandatory probati…
Background and objectives. The majority of environmental education takes place in informal settings, of which so-called free-choice learning is typical. What is understood by this is a kind of learning which is self-determined and driven by the needs and interests of the learner. The voluntariness of participation in interventions and the fact that they take place in turbulent action settings l…
