At the beginning of the transition period, the public debt in Romania was insignificant. However, during the following years, the accumulating process accelerated. Although the indebtedness degree continues to be smaller than registered levels in other European countries, more dangerous could be...

In order to obtain plausible scenarios of economic development in Romania up to the 2015 horizon, we used a mix of forecasting models, from ones classified as “medium-term” to those covering longer forecasting periods. Based on the analysis of the economic transition period we mainly used...

As asserted in standard literature, there is an implicit circular relationship between the productivity growth and the potential level of production (and, consequently, the estimation of the natural rate of unemployment is also altered). In order to avoid such emerging impediment in any...

The paper analyses the dynamics and structure of GDP in Romania during the transition period. Starting from the classical Cobb-Douglas production model, the paper investigates different scenarios for the Romanian economy on the basis of different assumptions regarding the model’s parameters....

The collapse of former communist regime in Central and Eastern Europe opened the transition period from centrally planned to market oriented economies. Thus, the exploration of economic systems in the special situation of transition has become an interesting research topic. The exposition plan...

Economic theory tells that a command system allocates resources poorly because of the impossibility of economic calculation. Therefore, once prices are freed and start to operate at quasi-equilibrium (market-clearing) levels, the hidden inefficiencies come into the open and a massive resource...

In this paper we compute performance indices like those from Mereuta et all. (2007) using the eigenvalues and the eigenvectors of the variance-covariance matrix of these indices. The eigenvalues are used in this paper to give natural weights to the performance indices in order to compute the...

The paper aims to model the underground economy using two different models: one based on the labor supply method and a generalized model for the allocation of time. The model based on the labor supply method is conceived as a simulating one in order to determine some reasonable thresholds of the...

There is a long period since the problem of public debt sustainability captures the attention of economists. However, there is no unanimity concerning an adequate unique sustainability indicator or function generally accepted. Just in this line of elaborating new models and improving...

The study concentrated on demonstrating how non-linear modelling can be useful to investigate the behavioural of dynamic economic systems. Using some adequate non-linear models could be a good way to find more refined solutions to actually unsolved problems or ambiguities in economics. Beginning...
