Does corruption serve as an economic lubricant?

=== === The new study introduces a new perspective on the role of corruption in economic growth and provides quantitative estimates of the impact of corruption on the growth and importance of the transmission channels. In our ordinary least squares estimations, we find that a 1% increase in the corruption level reduces the growth rate by about 0.72% or, expressed differently, a one-unit increase in the corruption index reduces the growth rate by 0.545 percentage points. The most important channel through which corruption affects economic growth is political instability, which accounts for about 53% of the total effect. We also find that corruption reduces the level of human capital and the share of private investment.
