This empirical study analyzes market and currency risk premia during financial and political crises within the theoretical framework of the international asset pricing model of Adler and Dumas (1983). The econometric specification extends the multivariate GARCH approach of De Santis and Gerard...

We investigate the consequences for value-at-risk and expected shortfall purposes of using a GARCH filter on various mis-specified processes. In general, we find that the McNeil and Frey (2000) two step procedure has very good forecasting properties. Using an unconditional non filtered tail...

This paper shows that in financial markets with endogenous asset supply and demand, both rational and noise traders do coexist in the long run. The finding implies that financial markets are neither informationally nor allocationally efficient. While rational traders have a consistently higher...

This paper analyzes the effects that uncertainty about economic fundamentalshas on aggregate trading volume. First, the trading volume of an investor facinga standard consumption portfolio choice problem is derived. It is found that if theparameters describing the investment opportunity set...

The estimation of multivariate GARCH models remains a challenging task, even in modern computer environments. This manuscript shows how Independent Component Analysiscan be used to estimate the Generalized Orthogonal GARCH model in a fraction of the time otherwise required. The proposed method...

No, not really. Responding to lingering concerns about the reliability of SVARs, Christiano et al (NBER Macro Annual, 2006, “CEV”) propose to combine OLS estimates of a VAR with a spectral estimate of long-run variance. In principle, thiscould help alleviate specification problems of SVARs in...

Stylized facts on output and interest rates in the U.S. have so far proved hard to match with business cycle models. But these findings do not acknowledge that the economy might well be driven by different shocks, and by each in different ways. I estimate covariances of output, nominal and real...

Prospect theory has found an increasing attention in many fields of economics. However, it has scarcely been addressed in a macroeconomic growth model. In an earlier paper we introduced prospect theory into a stochastic growth model. This paper focuses on linking the Euler equation induced by...

We introduce a new approach on shape preserving estimation of cumulative distribution functions and probability density functions using the wavelet methodology for multivariate de- pendent data. Our estimators preserve shape constraints such as monotonicity, positivity and integration to one,...

This paper is about contagion and interdependence among Central European economies. It investigates the extent to which country-specific shocks spread across these countries beyond the normal channels of interdependence, taking into account common external shocks. To model such shocks, we make...
