Can Taxes Tame The Banks
Michael P. Devereux, Niels Johannesen, John Vella: Can taxes tame the banks? Evidence from European bank levies, EPRU Working Paper Series 2013-05, 2013
In the wake of the financial crisis, a number of countries have introduced levies on bank borrowing with the aim of reducing risk in the financial sector. This paper studies the behavioral responses to the bank levies and evaluates the policy. We find that the levies induced banks to borrow less but also to hold more risky assets.The reduction in funding risk clearly dominates for banks with high capital ratios but is exactly offset by the increase in portfolio risk for banks with low capital ratios. This suggest that while levies have reduced the total risk of relatively safe banks, they have done nothing to curb the risk of relatively risky banks, which presumably pose the greatest threat to financial stability.
