Since Mandelbrot's seminal work (1963), alpha-stable distributions with infinite variance have been regarded as a more realistic distributional assumption than the normal distribution for some economic variables, especially financial data. After providing a brief survey of theoretical results on...

This paper considers Bayesian regression with normal and doubleexponential priors as forecasting methods based on large panels of time series. We show that, empirically, these forecasts are highly correlated with principal component forecasts and that they perform equally well for a wide range...

Mixed-data sampling (MIDAS) regressions allow to estimate dynamic equations that explain a low-frequency variable by high-frequency variables and their lags. When the difference in sampling frequencies between the regressand and the regressors is large, distributed lag functions are typically...

Density forecasts have become quite important in economics and finance. For example, such forecasts play a central role in modern financial risk management techniques like Value at Risk. This paper suggests a regression based density forecast evaluation framework as a simple alternative to other...

Under the symmetric á-stable distributional assumption for the disturbances, Blattberg et al (1971) consider unbiased linear estimators for a regression model with non-stochastic regressors. We consider both the rate of convergence to the true value and the asymptotic distribution of the...

This study examines differences in the interest rate response to an ECB policy impulse in the euro area, the new EU-member states, and in the other non-eurozone EU countries in order to gauge the degree of interest rate alignment in Europe. To this end, PANIC, a Panel Analysis of...

Based on the concept of covered interest parity it is shown that the money markets in Poland, the Czech Republic, Hungary, and the Slovak Republic meanwhile display a high degree of international integration with the euro area. Integration has strengthened continuously in the review period of...

A test of speculative efficiency on the foreign exchange markets of Poland, the Czech Republic, Hungary and the Slovak republic was unable to identify a cointegration relationship between forward and spot rates against the euro for the period between 1999 and mid-2002. Econometric studies...

Im Rahmen eines Tests der spekulativen Effizienz auf den Devisenmärkten Polens, der Tschechischen Repubik, Ungarns und der Slowakei kann für den Beobachtungszeitraum von 1999 bis Mitte 2002 keine Kointegrationsbeziehung zwischen Termin- und Kassakursen gegenüber dem Euro nachgewiesen werden....
