We use high resolution satellite data on the proportion of buildings in a 250x250 meter cell to study the evolution of human settlement in Ghana over a 40 year period. We find a strong increase in built-up area over time, mostly concentrated in the vicinity of roads, and also directly on the coast. We find strong evidence of agglomeration effects both in the static sense—buildup in one cell predicts buildup in a nearby cell—and in a dynamic sense—buildup in a cell predicts buildup in that cell later on and an increase in buildup in nearby cells. These effects are strongest over a 3 to 15 Km radius, which corresponds to a natural hinterland for a population without mechanized transportation. We find no evidence that human settlements are spaced more or less equally either over the landscape or along roads. This suggests that arable land is not yet fully utilized, allowing rural settlements to be separated by areas of un-farmed land. By fitting a transition matrix to the data, we predict a sharp increase in the proportion of the country that is densely built-up by the middle and the end of the century, but no increase in the proportion of partially built-up locations.
The power of large internet platforms to amplify or silence certain voices at a scale that can alter major political outcomes poses a grave threat to democracy.
Many studies document low rates of financial literacy and suboptimal levels of participation in financial markets. These issues are particularly acute among women. Does this reflect a self-reinforcing trap? If so, can a nudge to participate in financial markets generate knowledge, confidence, and further increase informed participation? We conduct a large field experiment that enables and incentivizes working-age men and women---a challenging group to reach with standard financial training programs---to trade stocks for four to seven weeks. We provide no additional educational content. We find that trading significantly improves financial confidence, as reflected in stock market participation, objective and subjective measures of financial knowledge, and risk tolerance. These effects are especially strong among women. Participants also become more self-reliant and consult others less when making financial decisions.
This article examines the AKP’s youth politics in the aftermath of the 2013 Gezi Protests. It focuses on a seemingly mundane cultural practice of essay writing and student essay competitions to investigate the party’s message and methods in addressing young people. In particular, it examines the politics of history and emotional politics in the party's effort to construct and administer youth publics. The article argues that the AKP’s power is embedded in and reproduced by the articulation of political differences and mobilization of emotions, which play a significant role in the party’s broader bid to reorganize society, redefine collective identity, and control dissent.
An assessment of Russia that suggests that we should look beyond traditional means of power to understand its strength and capacity to disrupt international politics.
We measure the effects of a network of heroes in legitimizing and diffusing extreme political behaviors. Exploiting newly-declassified intelligence files, novel voting data and regimental histories, we show the home municipalities of French line regiments arbitrarily rotated through Philippe Petain's command during the heroic WWI battle of Verdun, though similar before WWI, increasingly espouse Petain's authoritarian political views thereafter, raising 7% more active Nazi collaborators per capita during the Petain-led Vichy regime (1940-44). The effects are similar across joining Fascist parties, German forces, paramilitaries hunting Jews and the Resistance, and collaborating economically.
After generations of foreign policy failures, the United States can finally try to make the world safer―not by relying on utopian goals but by working pragmatically with nondemocracies.
