In the other presentation titled “Country-by-Country Reporting Data and Locations of European Banks: Profits Shifted to Tax Havens, Turnover and Employees Elsewhere?”, he presented some preliminary results for banks and profit shifting and discussed the usefulness of the recently published country-by-country reporting data.
