    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.

    Spatial inequality, civil conflict and cells: a dynamic spatial probit approach
    (2021) Ríos, Vicente; Manotas Hidalgo, Beatriz; Gianmoena, Lisa; Economía; Ekonomia
    This study examines the link between spatial income inequality and civil conflict in Africa. To that end we extend traditional empirical models of conflict to account for both endogenous and exogenous spatial interaction effects in the process of conflict by means of modern spatial econometric techniques. Using a geographically disaggregated annual high-resolution cell data for a sample of African countries during the period 1998 to 2013, we quantify the effect of spatial inequality on the probability of conflict incidence. Estimates show the existence of a positive and statistically significant relationship between spatial income inequality and conflict in African regions. This is partly due to the role played by spatial spillovers induced by spatial inequality in neighboring regions. The observed link is robust to the inclusion in the analysis of different explanatory variables that may affect both conflict and spatial inequality such as the level of economic development, the endowment of natural resources, infrastructures, geographical conditions, population density, fractionalization, polarization, social exclusion, or the share of urban population. The observed positive effect does not depend on the the level of data disaggregation, the type of conflict, the spatial inequality metric used in the analysis and the econometric specification employed to capture the nature of spatial spillovers.

    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.
