We study the relationship between VARMA and factor representations of a vector stochastic process. We observe that, in general, vector time series and factors cannot both follow finite-order VAR models. Instead, a VAR factor dynamics induces a VARMA process, while a VAR process entails VARMA...

This paper proposes a measure of the extent to which a financial sector is connected to the real economy. The Measure of Connectedness is a measure of the composition of assets, namely the share of credit to the non-financial sectors over the total credit market instruments. The aggregate...

The recent crisis has revealed the potentially dramatic consequences of allowing the build-up of an overstretched leverage of the financial system, and prompted proposals by bank supervisors to significantly tighten bank capital requirements as part of the new Basel 3 regulations. Although these...

In this paper we identify and measure the effects of credit shocks in a small open economy. To incorporate information from a large number of economic and financial indicators we use the structural factor-augmented VARMA model. In the theoretical framework of the financial accelerator, we...

We propose a measure of the extent to which a financial sector is connected to the real economy. The Measure of Connectedness is the share of credit market instruments represented by claims whose direct counterpart belongs to the non-financial sectors. The aggregate U.S. Measure of Connectedness...

Temporal aggregation in general introduces a moving average (MA) component in the aggregated model. A similar feature emerges when not all but only a few variables are aggregated, which generates a mixed frequency model. The MA component is generally neglected, likely to preserve the possibility...
