Does corruption affect firm growth? New evidence from Mozambique

Abstract This paper estimates the effect of corruption on firm growth; specifically, in the context of Mozambique. Using instrumental variable estimation to address potential problems of endogeneity and measurement error, the paper finds that corruption has a robust negative effect on sales and productivity growth. The effect is not constant but declines as firm performance drops and corruption increases. This means corruption is most damaging to high-performance firms, meaning firms with higher sales and productivity growth rates, and to firms with lower bribe rates. For low-performance firms and firms with higher bribe rates, the effect gradually approaches zero. The paper contributes to the literatures in two ways. First, it offers a more nuanced understanding of the relationship between corruption and firm growth by showing that the effect of corruption is conditional on firm-specific factors. Second, the paper extends the empirical research on corruption and firm growth to Southern Africa, which has previously been excluded from the literature.
