We evaluate the impact of firm-specific export subsidies on exports in Colombia. Using a two-stage Heckman selection procedure, we obtain firm-specific predicted subsidy amounts that can be explained by the characteristics that determine the firms' eligibility for the government support and its...

This paper develops an estimator for higher-order spatial autoregressive panel data error component models with spatial autoregressive disturbances, SARAR(R,S). We derive the moment conditions and optimal weighting matrix without distributional assumptions for a generalized moments (GM)...
