We compare testing strategies for Granger noncausality in vector autoregressions (VARs)that may or may not have unit roots and cointegration. Sequential testing methods are examined; these test for cointegration and use either a differenced VAR or a vector error correction model(VECM), in which to...

Government, business R&D organizations are currently publishing many short-, medium- and long-term forecasts. Herewith, the consumers of such information, as a rule are not aware of the way the estimates were made. As a result, when making a choice, which forecast should the most trustful, the...

This paper estimates ordered logit models for bank ratings which include a country index to capture country-specific variation. The empirical findings support the hypothesis that the individual international bank ratings assigned by Fitch Ratings are underpinned by fundamental quantitative...

We explore how the ECB sets interest rates in the context of policy reaction functions. Using both real-time and revised information, we consider linear and nonlinear policy functions in inflation, output and a measure of financial conditions. We find that amongst Taylor rule models, linear and...

This paper studies optimal real time monetary policy when the central bank takes the volatility of the output gap and inflation as proxy of the undistinguishable uncertainty on the exogenous disturbances and the parameters of its model. The paper shows that when the uncertainty surrounding a...

The degree of exchange rate pass-through to domestic goods prices has important implications for monetary policy in small open economies with floating exchange rates. Evidence indicates that pass-through is faster to import prices than to consumer prices. Price setting behaviour in the...

Pornind de la faptul ca colinearitatea genereaza distorsiuni atat ale valorilor estimate cat si ale testelor statistice, la inceputul prezentei lucrari sunt inventariate consecintele respectivelor distorsiuni si este construita o metoda de identificare a tipurilor de colinearitate, avandu-se in...

We consider a nonlinear vector model called the logistic vector smooth transition autoregressive model. The bivariate single-transition vector smooth transition regression model of Camacho (2004) is generalised to a multivariate and multitransition one. A modelling strategy consisting of...

El presente estudio contrasta la hipótesis de una relación no lineal entre la inflación y el crecimiento de la actividad económica del Perú con datos que cubren el periodo enero 1993 - junio 2012. Se usa una familia de modelos dicotómicos que enfatizan la relación entre las fases de...
