    Addressing oil spills and agricultural productivity. Evidence of pollution in Nigeria
    (2021) Manotas Hidalgo, Beatriz; Ekonomia; Institute for Advanced Research in Business and Economics - INARBE; Economía
    This paper examines how the pollution generated by oil operations in Nigeria can affect agricultural total factor productivity. I analyze oil spills, which are the main ecological disaster in Nigeria and lead to major environmental, economic, and social problems. Following a consumer-producer household framework, and applying a difference-and-difference approach, I estimate an agricultural production function. I find that farmers located less than 10 kilometers from oil spills suffer a relative reduction in agricultural output of around 2.73%. I also examine alternative mechanisms and find that oil-spill pollution can explain my results. I detect less owner-occupied land and a drop in labor income in urban areas close to oil spills, which could also be explained by a decrease in the labor productivity component. This study highlights an externality through which the oil industry affects living conditions in rural areas and stresses the importance of clean-up in areas close to oil spills.

    The role of ethnic characteristics in the effect of income shocks on African conflict
    (Elsevier, 2021) Manotas Hidalgo, Beatriz; Pérez Sebastián, Fidel; Campo-Bescós, Miguel; Ekonomia; Ingeniaritza; Institute for Advanced Research in Business and Economics - INARBE; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Economía; Ingeniería
    This paper disentangles the ethnic drivers of the effect of food-related income shocks on African conflict employing geo-localized information. We consider diversity and political ethnic variables and several conflict definitions. We find that differentiating between organized armed-force and non-organized conflict can be more informative than between factor and output conflict. We show evidence that conflict is driven by the opportunity cost and state capacity mechanisms. Furthermore, ethnic cleavages have a large role in the transmission process of income shocks on organized armed-force conflict; whereas their role in non-organized violence is more limited. The sensitivity to ethnic heterogeneity for producer-price and droughts shocks is much larger than for consumer-price changes.
