Financial time series analysis has focused on data related to market trading activity. Next to the modeling of the conditional variance of returns within the GARCH family of models, recent attention has been devoted to other variables: first, and foremost, volatility measured on the basis of...

This paper supports the view that the deep roots of the current global crisis, which has taken the form of a mainly financial crisis, are related to a global fundamental unbalance in income distribution. There are two dimensions of the unbalance. The first one is between capital and labour...

The economic collapse of 2007-10 is described as a debt deflation crisis triggered by a speculative bubble. The basic causes are traced back to the policy choices of the great capitalist powers governing globalization. Market liberalization and the TRIPS agreements work as a sort of global...

The performance of tax receipts in Italy during the period 1978-2006 is analysed through the relationship between the growth of revenue and the evolution of the macroeconomic framework. Series of actual tax receipts are adjusted to take account of discretionary measures, transformed into...

Many ways exist to measure and model financial asset volatility. In principle, as the frequency of the data increases, the quality of forecasts should improve. Yet, there is no consensus about a "true" or "best" measure of volatility. In this paper we propose to jointly consider absolute daily...

We analyze several measures of volatility (realized variance, bipower variation and squared daily returns) as estimators of integrated variance of a continuous time stochastic process for an asset price. We use a Multiplicative Error Model to describe the evolution of each measure as the product...
