We combine the issues of dealing with variables sampled at mixed frequencies and the use ofreal-time data. In particular, the repeated observations forecasting (ROF) analysis of Stark andCroushore (2002) is extended to an autoregressive distributed lag setting in which the regressorsmay be...

With the development of real-time databases, N vintages are available for T observations instead of a single realization of the time series process. Although the use of panel unit root tests with the aim to gain in efficiency seems obvious, empirical and simulation results shown in this paper...

This paper compares two approaches towards the empirical inertia of inflation and output. Two variants that produce persistence are added to a baseline DSGE model of sticky prices: 1) sticky information applied to firms, workers, and households; and 2) a backward-looking inflation indexation...

By distinguishing between discretionary and non-discretionary fiscal policy, this paper analyses the stability of fiscal rules for EMU countries before and after the Maastricht Treaty. Using both Instrumental Variables and GMM techniques, it turns out that discretionary fiscal policy remains...

The purpose of this paper is to propose a new measure of contagion. Our approach to testing contagion is based on the frequency analysis of causality developed recently by Breitung and Candelon (2004). This approach handles, in a unified framework, several of the statistical problems identified...

Empirical evidence shows that government spending crowds in private consumption, a Keynesian phenomenon. The current state of the art, New Keynesian models based on optimising households and _rms, is not able to predict such a result. We show with a graphical framework as well as a formal model...

This paper proposes a new testing approach for panel unit roots that is, unlike previously suggested tests, robust to nonstationarity in the volatility process of the innovations of the time series in the panel. Nonstationarity volatility arises for instance when there are structural breaks in...

It is well known that cointegration between the level of two variables (labeled Y_{t} and y_{t} inthis paper) is a necessary condition to assess the empirical validity of a present-value model (PVand PVM, respectively, hereafter) linking them. The work on cointegration has been so prevalentthat...

We propose an approach for checking the data admissibility of non-stationary multivariate time series models (VAR or VARMA) through that of their implied individual ARIMA specifications. In particular we show that the presence of different kinds of common cyclical features restrictions, leading...
