We present a unified and up-to-date overview of temporal aggregation techniques for univariate and multivariate time series models explaining in detail how these techniques are employed. Some empirical applications illustrate the main issues.

We consider how unit root and stationarity tests can be used to study the convergence properties of prices and rates of inflation. Special attention is paid to the issue of whether a mean should be extracted in carrying out unit root and stationarity tests and whether there is an advantage to...

This work examines how much of the variation in emerging market economies' (EMEs) spreads can be ascribed to 'country-specific' factors rather than to 'common' factors, once the existence of an interaction between the state of macroeconomic fundamentals and global financial conditions is...

In this article, we analyse how much of the reduction in emerging markets spreads can be ascribed to specific factors - linked to the improvement in the 'fundamentals' of a given country - rather than to common factors - linked to global liquidity conditions and agents� degree of risk...

Quantile aggregation (or 'Vincentization') is a simple and intuitive way of combining probability distributions, originally proposed by S. B. Vincent in 1912. In certain cases, such as under Gaussianity, the Vincentized distribution belongs to the same family as that of the individual...

We investigate the relationship between macroeconomic conditions and banks' balance sheets by referring to a modified version of the Bank of Italy Quarterly Model (BIQM), regularly used for forecasting and policy analysis. In particular, we examine how regulatory bank capital and private sector...

This paper analyses the monetary transmission mechanism in the euro area through the use of large scale macroeconomic models at the disposal of the European Central Bank and the National Central Banks of the Eurosystem. The results reported are based on a carefully designed common simulation...

This paper reviews the existing empirical evidence on the short-term impact on prices of fiscal variables and assesses it against new results from harmonised simulations, conducted with six well-established econometric models used by the ECB and five national central banks (NCBs) of the...

The recent empirical evidence documenting the presence of asymmetries in business cycles represents a challenge for the standard equilibrium models of real business cycle. These models successfully explain most first and second moments of the actual time series, but cannot replicate non-linear...

The paper surveys different approaches to the estimation of the underground economy. First, the focus is on the methodologies adopted by the Italian and French Statistical Institutes, respectively based on the exhaustive estimate of the labour input and on tax compliance data. Secondly, we...
