Bereits 1947 wurde im Rahmen der Havanna-Charta eine Initiative zur Schaffung einer internationalen Wettbewerbsordnung unternommen, auf die sich jedoch die internationale Staatengemeinschaft nicht einigen konnte. Die handelspolitischen Vertragsentwürfe wurden dann Basis für das General...

In this article we derive conditions which ensure the non-negativity of the conditional variance in the Hyperbolic GARCH(p,d,q) (HYGARCH) model of Davidson (2004). The conditions are necessary and sufficient for p=1 and sufficient for p=2 and emerge as natural extensions of the inequality...

This paper examines the link between inflation, output growth and their respective variabilities. We employ a bivariate GARCH model, which incorporates mean and level effects, to investigate in a unified empirical framework all the possible interactions between the four variables. We show that...

In this paper we model the adjustment process of European Union Allowance (EUA) prices to the releases of announcements at high-frequency controlling for intraday periodicity, volatility clustering and volatility persistence. We find that the high-frequency EUA price dynamics are very well...

This paper considers a formulation of the extended constant or time-varying conditional correlation GARCH model which allows for volatility feedback of either sign, i.e., positive or negative. In the previous literature, negative volatility spillovers were ruled out by the assumption that all...

We investigate the impact of the European Central Bank’s monetary policy communication during the press conference held after the monthly Governing Council meeting on the EUR-USD exchange rate in high-frequency. Based on the method of Content Analysis we construct communication indicators for...

In this paper we develop an asymptotic theory for the Quasi-Maximum Likelihood Estimator (QMLE) of the parametric GARCH-in-Mean model. The asymptotics is based on a study of the volatility as a process of the model parameters. The proof makes use of stochastic recurrence equations for this...
