This paper deals with the estimation of the risk-return trade-off. We use a MIDAS model for the conditional variance … and allow for possible switches in the risk-return relation through a Markov-switching specification. We find strong … evidence for regime changes in the risk-return relation. This finding is robust to a large range of specifications. In the …

This paper considers the problem of estimating a linear model between two heavy-tailed variables if the explanatory variable has an extremely low (or high) value. We propose an estimator for the model coefficient by exploiting the tail dependence between the two variables and prove its...

We employ a wavelet approach and conduct a time-frequency analysis of dynamic correlations between pairs of key traded assets (gold, oil, and stocks) covering the period from 1987 to 2012. The analysis is performed on both intra-day and daily data. We show that heterogeneity in correlations...

During the recent crisis, lags in the transmission mechanism of economic shocks, together with monetary and fiscal policy, made it difficult to assess the evolving dynamics of creditworthiness. As such, developments in financial markets became a key guide for investors and policymakers in...

We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances. In so doing, we provide an exact distribution-free method to test uniform linear restrictions in multivariate linear...
