In this paper, we revisit a frequently employed simplification within the WACC approach that company cost of capital kV is supposed to be invariant to the debt ratio and therefore equal to the unlevered cost kU . Even though we know from Miles and Ezzell (1980) that kV formally differs from kU ,...

In this paper, we analyze how tail risk impacts both asset prices and the optimal asset allocation. For this purpose, we consider an equilibrium model with investors exhibiting an empirically well-justifiable decreasing relative risk aversion (DRRA) and different investment horizons. In contrast...

This paper analyzes the funding advantage of green bonds and the determinants of what is referred to as the “greenium” (the “green” premium). To this end, we first separate the greenium from a simultaneously prevailing liquidity premium in empirical yield spreads. For green German...

In this study, we analyze whether model complexity improves accuracy of CoCo pricing models. We compare the out-of-sample pricing ability of four models using a broad dataset that contains all CoCos which were issued between January 1, 2013 and May 31, 2016 in euros. The regarded models include...

The paper revisits the two major concepts for average historical returns, i.?e., the arithmetic mean and the geometric mean, in order to clarify which approach must be used for which application. Conducting a rigorous derivation with a geometric Brownian motion, we can explain that the...
