Foreign aid and growth: A Sp P-VAR analysis using satellite sub-national data for Uganda

We develop a measurement strategy for the impact of foreign aid based on a regional spatial panel vector-autoregressive model (Sp P-VAR). We illustrate the strategy using Ugandan districts. Data for the regional units (ADM2) is assembled combining satellite sources for socio-economic activity, geo-located aid disbursements, and traditional household surveys. We find statistically significant positive and persistent effects of aid shocks on nighttime luminosity. Mapping nightlights to economic activity, the results suggest that the economic magnitude of these effects is small, but significant - with a multiplier between 4 and 5 in the long-run. The VAR addresses endogeneity concerns associated with non-random aid assignment.
