Credit bureaus and financial constraints do corruption matter? حسب Mohamed Sami Ben Ali (14152038)

"…Our findings suggest that curbing corruption creates more efficient credit bureaus that, in turn, decrease financial constraints for firms. The subsample estimations confirm these findings and show that the higher and longer-term corruption in MENA countries than in Eastern European countries make credit bureaus’ less effective, imposing more financial constraints. …"
