The aim of this paper is to illustrate how the stability of a stochastic dynamic system is measured using the Lyapunov exponents. Specifically, we use a feedforward neural network to estimate these exponents as well as asymptotic results for this estimator to test for unstable (chaotic)...

This study investigates the impact of new information on the volatility of exchange rates. The impact of scheduled US and European macroeconomic news on the volatility of USD/EUR 5-minute returns was tested by using the Flexible Fourier Form method. The results were consistent with earlier...

This paper investigates the dependence of average stock market volatility on the timescale or on the time interval used to measure price changes, which dependence is often referred to as the scaling law. Scaling factor, on the other hand, refers to the elasticity of the volatility measure with...

No consensus has emerged on how to deal with overnight returns when calculating realized volatility in markets where trading does not take place 24 hours a day. This paper explores several common volatility applications, investigating how the chosen treatment of overnight returns affects the...

This article empirically studies the linkages between financial variable downturns and economic recessions. We present evidence that real asset prices tend to lead real cycles, while loan-to-GDP and loan-to-deposit ratios lag them. Using a probit analysis, we document that downturns in real...

In this article we provide a summary of empirical results obtained in several economics and operations research papers that attempt to explain, predict, or suggest remedies for financial crises or banking defaults, as well as outlines of the methodologies used. We analyze financial and economic...

This paper investigates the extent to which euro area monetary policy has responded to evolving economic conditions in individual member states as opposed to the euro area as a whole. Based on a forward-looking Taylor rule-type policy reaction function, we conduct counterfactual exercises that...

In this paper we incorporate the term structure of interest rates into a standard inflation forecast targeting framework. Learning about the transmission process of monetary policy is introduced by having heterogeneous agents – ie central bank and private agents – who have different...

In this paper we analyse disinflation policy in two environments. In the first, the central bank has perfect knowledge, in the sense that it understands and observes the process by which private sector inflation expectations are generated; in the second, the central bank has to learn the private...

Using recently developed modelling methodology of Economic Tracking Portfolios (ETP), we find that it is possible to forecast future values of inflation and changes in industrial production in the United States and at least three core euro countries – Italy, France and Germany – utilising...
