This paper proposes an estimate of the Hungarian real exchange rate=20 misalignments using fractionally integrated threshold models (FI-STARMA and=20= FI-TARMA=20 processes). This allows us to simultaneously take into account two types of=20 persistence: a long memory behavior due to the...

The episodes of stock market crises in Europe and the U.S.A.since the year 2000,and the fragility of the international stock markets,have sparked the interest of researchers in understanding and in modeling the markets’ rising volatilities in order to prevent against crises.Portfolio managers...

In recent years, wavelets have become widely used in physics, engineering, and mathematics. They have been used for signal processing, image processing, numerical computation, and data compression. Wavelets have not, however, been used very much in the fields of Economics, Econometrics, and...

We consider mean-reverting stochastic processes and build a self- consistent model for forward price dynamics and their applications in power industries. This model with stochastic volatility of the forward price is built using the ideas and equations of stochastic differential geometry in order...

We present several Markov chain Monte Carlo simulation methods that have been widely used in recent years in econometrics and statistics. Among these is the Gibbs sampler, which has been of particular interest to econometricians. Although the paper summarizes some of the relevant theoretical...

The essential idea of equilibrium search models of labour market behaviour is that wage policy matters. In contrast, the stylized neoclassical competitive model predicts that firms paying a wage above the competitive equilibrium will disappear; those offering less will attract no workers. The...
