Necessary and sufficient restrictions for existence of a unique fourth moment of a univariate GARCH(p,q) process

Zadrozny, Peter A. (contributor) - 2005

A univariate GARCH(p,q) process is quickly transformed to a univariate autoregressive moving-average process in squares of an underlying variable. For positive integer m, eigenvalue restrictions have been proposed as necessary and sufficient restrictions for existence of a unique mth moment of...

Structural vector autoregressions : checking identifying long-run restrictions via heteroskedasticity

Lütkepohl, Helmut; Velinov, Anton - 2014

Long-run restrictions have been used extensively for identifying structural shocks in vector autoregressive (VAR) analysis. Such restrictions are typically just-identifying but can be checked by utilizing changes in volatility. This paper reviews and contrasts the volatility models that have...

Corporate debt, hybrid securities and the effective tax rate

Panteghini, Paolo (contributor) - 2008

In this article we use contingent-claim analysis to calculate the effective tax rate (ETR) under corporate debt finance. In particular, we deal with both pure debt and two of the most well-known hybrid securities, i.e., convertible, and reverse convertible bonds. We show that: 1) effective...
