Two interesting articles from the newest number of the Journal of Development Studies:
Why were So Many Social Scientists Wrong about the Green Revolution? By Orr. Most social scientists once took a negative view of the socio-economic consequences of the Green Revolution. Events have since proved them wrong. Using Bangladesh as an example, we offer three reasons why social scientists were mistaken. One is the focus on village studies at the expense of nationally representative surveys. Another is insufficient appreciation of the technical limits of the new rice technology. The third is a misleading model of agrarian change. The inability of village studies to validate generalisations, the reluctance to abandon the historical model of de-peasantisation, and opposing beliefs about how to evaluate socio-economic consequences created a Rashomon Effect that made the controversy hard to resolve.
Mobile Phones and Economic Development in Rural Peru. By Beuermann, McKelvey & Vakis.
We estimate the effects of mobile phone coverage on different measures of economic development. We exploit the timing of mobile coverage at the village level merging it with a village-level panel dataset for rural Peru. The main findings suggest that mobile phone expansion has increased household real consumption by 11 per cent, reduced poverty incidence by 8 percentage points and decreased extreme poverty by 5.4 percentage points. Moreover, those benefits appear to be shared by all covered households regardless of mobile ownership.
Unfortunatelly I did not find the full papers online. The abstracts are self-explanatory.
