We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. We also show that variance decompositions define weighted, directed networks, so...

The aim of this paper is to demonstrate how the change in actual and potential market risks in the Dow Jones Industrial Average (DJIA) during the two-year period 2007-2008 can be analyzed with the help of-analysis. In the empirical analysis, the average of the Lyapunov exponents for the dynamic...

In this paper we discuss some statistical pitfalls that may occur in modeling cross-dependences with copulas in financial applications. In particular we focus on issues arising in the estimation and the empirical choice of copulas as well as in the design of time-dependent copulas.

This paper argues that observations of non-stationary choice behavior need notnecessarily imply specific properties of the individual’s discount function. As weshow, the observed “anomalies” in intertemporal choice can alternatively be explained by an individual’s perception of the risk...

The aim of this paper is to study the impact of bankruptcy law on financing, investment, default and liquidation decisions of firms. We build a model in which a firm can finance its investment by issuing debt. The investment is risky. Because of risk, the firm may default. The firm manager takes...
