This thesis consists of four essays: The first essay entitled “Tax Effects on Asset Pricing – New Evidence from Tax Reform Announcements in Germany”, co-authored with Michael Overesch, Chair of Business Taxation at the University of Cologne, not only presents price effects for German shares given rumors about lowering the German corporate tax rate but also shows price effects for bonds following a substantial cut in the German personal interest tax rate. The second essay “Capital Income Taxes and the Ex-Day Premium – New Evidence from a Cross-Country Analysis”, again co-authored with Michael Overesch, presents new evidence on the tax status of the marginal investor and whether the ex-day price drop equals the dividend payment. The third essay “Corporate Tax Planning and the Payout Ratio of Firms – Is the Dividend Penalty Linked to ETRs?”, co-authored with Pia Olligs, doctoral research assistant at the University of Cologne, sheds light on the question whether corporate tax avoiding firms do also react more sensible to their shareholders’ personal dividend tax rates. The concluding essay “Capital Market Reaction to Tax Avoidance: Evidence from LuxLeaks”, co-authored with Birgit Hüsecken, doctoral research assistant at the University of Cologne, and Michael Overesch, shows robust evidence that the revelation of corporate tax avoidance, when there is no threat of back taxes or penalties, does increase firm value.
