Under the conditions of OLS use in order to perform multiple linear regressions, both the estimated parameters values and also computed values of some statistical tests such as coefficient of determination, Fisher test or Student test are influenced by collinearity1. The respective influence is...

In this paper, we propose a new model with random variance components for estimating small area characteristics. Under the proposed model, we derive the empirical best linear unbiased estimator, an approximation to terms of order and an estimator whose bias is of order for its mean squared...

The paper analyzes the dependencies between the variation in the indices of the exchange rate, electric, thermal power, gas and total energy, as well as the international oil price and their influence on the level of inflation. The series of data refer to the period January 1999 – December...

The paper analyzes the circumstances in which the combination of forecasts yields better results than the use of the forecasts separately. We propose a method of combining forecasts based on their efficiency on long and medium-term using as benchmarks the combination of forecasts based on...

This paper shows that dynamics of fixed capital productivity at macroeconomic level is related to changes in the indicators and relationships which are fundamental to the economic stability (index of gross fixed capital formation, consumption-fixed capital accumulation relationship, and external...

The paper analyzes the monetary policy transmission mechanism in Romania focusing on the exchange rate channel. The analysis is made in the context of an economy described by a mix of institutional and market behaviors illustrated by a SVAR model in which the restrictions imposed on the...

In the present study, we estimate the parameters of the Generalized Hyperbolic Distribution for a series of stock index returns including the Romanian BETC and indexes from other two Eastern European countries, Hungary and the Czech Republic. Using different econometric techniques, we...

Option-implied risk-neutral densities incorporate market expectations with respect to the future course of option underlyings. Under the risk neutrality assumption various methods have been developed. In this paper, we look into two of them: parametric mixture of lognormals method and...

In this paper we utilize a semi-parametric approach with multiplicative adjustment to estimate the distributions for a series of stock index returns including developed and emerging economies. The semi-parametric approach has potential improvements over both pure parametric and non-parametric...

The new (2002) version of the "Pre-Accession Economic Program" has to take into account both the experience accumulated in the implementation of its previous (2001) form, and the changes occurred during 2001-2002 in the domestic and international environment, which have affected the Romanian...
