Do Remittances Diminish Social Violence?

This paper represents the first attempt to formalise the relationship between remittances and social violence by developing a model that predicts that migrants’ remittances lead to the reduction of social violence in the recipient economy under the condition that remittances increase the average product of labour. Using homicide data as an indicator of social violence, we tested our model’s prediction. Controlling for the endogeneity problem with appropriate instruments, we found that remittances tend to reduce social violence. We performed sensitivity analysis on remittances in the empirical specification and found it robust with an unchanged negative sign.     

Do African Manufacturing Firms Learn from Exporting?

We use firm-level panel data for the manufacturing sector in four African countries to investigate whether exporting impacts on efficiency, and whether efficient firms self-select into the export market. Based on simultaneous estimation of a production function and an export regression, our preferred results indicate significant efficiency gains from exporting, which can be interpreted as learning by exporting. We show that modelling unobserved heterogeneity by a flexible approach is important for deriving this conclusion. A policy implication of our results is that Africa would gain from orientating its manufacturing sector towards exporting.
