We propose a new method to identify the impact of a change in the tax burden on mutual fund inflows, exploiting a switch from an accrual-based to a realisation-based tax regime. We use quasi-experimental data from Italy where, starting from July 2011, the tax regime for domestic mutual funds was changed from an accruals basis to a realisation basis, while the taxation of foreign funds remained on a realisation basis. We find that the reform has had a positive effect on net inflows of Italian funds (the treated group) with respect to foreign funds (the control group). The effect is both economically and statistically significant. Moreover, we find no evidence that the increase in the demand for Italian funds came at the expense of foreign funds.

We study the effects on the stock market of a securities transaction tax (STT). In particular, we focus on the recent introduction of a STT in Italy. Indeed, a peculiarity of the Italian STT is that it only concerns stocks of corporations with a market capitalization above 500 million euros. We exploit this feature via a differences-in-differences approach (comparing taxed and non-taxed stocks both before and after the introduction of the new tax). We ?find that the new tax widened the bid-ask spread and increased volatility, while it left transaction volumes and returns substantially unaffected. Results are broadly similar using a regression discontinuity design, in which we confront the performance of stocks just above the threshold with those just below.

We study the effect of counterparty risk on the ability of Italian banks to access the foreign unsecured interbank market during the sovereign debt crisis in the second half of 2011. With the onset of the crisis, interest rates in the Italian interbank market soared and foreign lending decreased significantly. To isolate the effect of the rise in counterparty risk, we compare the funding of Italian banks with that of foreign banks’ branches and subsidiaries in Italy, which were presumably unaffected by the sovereign crisis insofar as they could count on the actual or potential support of their parent bank. We find that the rise in counterparty risk substantially decreased the probability of obtaining funds from foreign banks. When the analysis is restricted to Italian and foreign banks with relatively comparable asset compositions, the result holds. In addition, where safer banks or more stable lending relationships are involved the effect is attenuated.
