We study the identification and estimation of panel dynamic simultaneous equations models. We show that the presence of time-persistent individual-specific effects does not lead to changes in the identification conditions of traditional Cowles Commission dynamic simultaneous equations models....

Hierarchical analysis is considered and a multilevel model is presented in order to explore causality, chance and complexity in financial economics. A coupled system of models is used to describe multilevel interactions, consistent with market data: the lowest level is occupied by agents...

This paper considers the implications of the permanent/transitory decomposition of shocks for identification of structural models in the general case where the model might contain more than one permanent structural shock. It provides a simple and intuitive generalization of the influential work...

The ordinary least square method (OLS) is frequently used for the parameters estimation of different functional relationships. Having in view a series of properties revealed by the author, this paper presents the factors that determine the size of the estimated parameters and coefficients of...

This paper proposes likelihood-based procedures for determining the number of cointegrating vectors in the presence of constraints on the cointegration rank. The tests can be applied when a priori information suggests a lower bound on the number of common stochastic trends in the system. The...

In recent years, in Italy, the analysis of economic disparities at a regional level received much attention. In spite of this, improvements in quantitative analyses have not been adequately supported by new data releases. Adopting a procedure firstly developed by Di Fonzo [21], Italian main...

Monte Carlo simulation methods are used to generate independent series with short memory in volatility. Partial sums of there short memory series are formed and the volatilities of these partial sums are tested for long memory. Aggregating series with short memory valatilities results in indices...
