The relationship between natural resource wealth and civil conflict remains unclear, despite prolonged scholarly attention. Conducting a meta-analysis—a quantitative literature review—can help synthesize this broad and disparate field to provide clearer directions for future research. Meta-analysis tools determine both the aggregate effect of natural resources on conflict and whether any particular ways in which variables are measured systematically bias the estimated effect. I conduct a meta-analysis using sixty-nine studies from sixty-two authors. I find that there is no aggregate relationship between natural resources and conflict. Most variation in variable measurement does not alter the estimated effect. However, measuring natural resource wealth using Primary Commodity Exports and including controls for mountainous terrain and ethnic fractionalization all do significantly impact the results. These findings suggest that it may be worth exploring more nuanced connections between natural resources and conflict instead of continuing to study the overall relationship.

The relationship between increased tourism and increasing regional autonomy is quite nuanced and understudied. This article hypothesizes that only an increase in both regional air traffic and international tourism will impact the level of regional autonomy. Using the period after 10 countries were admitted to the European Union in 2004 as an example of a dramatic tourism increase, the article finds that countries with increased tourism, but without regional airports, did not experience a sudden increase in their regional autonomy. In Poland, however, the large number of growing regional airports and increased tourism did provoke regions to argue with the central government for more regional autonomy. These findings contribute to a better understanding of how international interventions impact regional decentralization preferences.

Previous models of individuals’ preferences for decentralization have focused on either economic- or identity-based motivations. In some cases, however, elites in rich regions with high inequality prefer decentralization contrary to their economic preferences. This paper proposes a model to explain these instances by focusing on the preferences of self-interested elites who manipulate a strong regional identity for personal gain. I develop the hypothesis that a strong regional economy, combined with a regional identity, provides the incentive for and the mechanism by which elites prefer decentralization. I test this hypothesis using the puzzling case of Ajara, Georgia, a rich region with high inequality and a strong regional identity where elites, contrary to expectations, pushed for decentralization. Results suggest that regional identities are used by elites in order to seize on a strong economy for personal gain. This motivates future study on the interaction between regional economies and identity.

What can researchers do to address anomalous survey and experimental responses on Amazon Mechanical Turk (MTurk)? Much of the anomalous response problem has been traced to India, and several survey and technological techniques have been developed to detect foreign workers accessing US-specific surveys. We survey Indian MTurkers and find that 26% pass survey questions used to detect foreign workers, and 3% claim to be located in the United States. We show that restricting respondents to Master Workers and removing the US location requirement encourages Indian MTurkers to correctly self-report their location, helping to reduce anomalous responses among US respondents and to improve data quality. Based on these results, we outline key considerations for researchers seeking to maximize data quality while keeping costs low.
