The Private Production of Safe assets (with M. Kacperczyk and G. Vuillemey) EFA 2018, AFA 2019, R&R Journal of Finance

Do claims on the private sector serve the role of safe assets? We answer this question using high-frequency panel data on prices and quantities of certificates of deposit (CDs) issued in Europe. We find that only very short-term private securities benefit from a premium for safety. Further, we show that the issuance of short-term CDs strongly responds to measures of safety demand. Our identification strategy uses a combination of (1) exclusion restrictions in a structural model of demand/supply equations, and (2) an instrumental variables approach. The private production of safe assets is stronger for issuers with high creditworthiness, and breaks down during episodes of market stress even though the market does not freeze. We conclude that even very short-term private assets are sensitive to changes in the information environment.

What if Dividends Were Tax-Exempt? Evidence from a Natural Experiment (with D. Isakov and J.P. Weisskopf)

We study the effect of dividend taxes on the payout and investment policy of publicly listed firms. To do so, we exploit a unique setting in Switzerland where some, but not all, firms were suddenly able to pay tax-exempt dividends to their shareholders following the corporate tax reform of 2011. Using a difference-in-differences specification, we show that treated firms permanently increase their payout by around 30% compared to control firms after the tax cut. The rise in dividends is not compensated by an equally-sized reduction in share repurchases. In the cross-section, the impact on payout is much less pronounced in firms where the controlling shareholders have more voting rights than cash-flow rights. However, reducing dividend taxes does not boost investment. The tax-inelasticity of investment is due to a significant drop in retained earnings and to the fact that equity issuances do not surge after the tax cut. Overall, we interpret our findings as evidence for the distortive effect of dividend taxes on the allocation of capital across firms.
