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 ,...

Die Bestimmung der Kapitalkosten von verschuldeten Unternehmen ist ein in der Literatur vielfach behandeltes und diskutiertes Forschungsgebiet. Dies ist insoweit kaum verwunderlich, da spätestens seit der weithin gebräuchlichen Anwendung von DCF-Verfahren zur Unternehmensbewertung die...

In this paper, we analyze the consequences of bank regulation on the size of the real sector. In particular, we address the question whether exogenous shocks on the return-risk characteristics of the technology and on the equity of the real sector are intensified or damped by a value-at-risk...

Who Should Merge with Whom? Financial Benefits and Costs from Mergers and Acquisitions Mergers and acquisitions are prominent forms of transactions that combine two firms in a way that one unit with a new asset and a new liability side arises. Since both the equity and the debt positions of the...

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...

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...

Correlated defaults and systemic risk are clearly priced in credit portfolio securities such as CDOs or index CDSs. In this paper we study an extensive CDX data set for evidence whether correlated defaults are also present in the underlying CDS market. We develop a cash flow based top-down...

In this paper, we apply Markowitz's approach of portfolio selection to government bond portfolios. As a main feature of our analysis, we use term structure models to estimate expected returns, return variances, and covariances of different bonds. Our empirical study for the German market shows...
