In this paper we proposed a model deriving from physics laws, which are associated to the investments impact upon the economic system potential. Defining several physics fundamental dimensions and starting from a series of assumptions, we tried to find their possible economic meaning and...

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...

Coming from standard economic growth theory and empirical evidences, we concentrated on the convergence process as a result of structural changes in economy. We investigate the differences among countries in EU in terms of the share in total economy of main sectors. Then, based on the spatial...

Empirical data show during the historical process of economic development profound structural changes in economy. One of the most important movements is from stages where the so-called tangible investments are predominant to those where intangible investments become predominant. Applying some...

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...

The study focused on the early stage of Romania’s transition to the market economy during 1990-1992, based on statistical data available at that time. Because of the inherited structural distortions, the persistence of strong forces of inertia and the incoherence of economic and monetary...

A balanced economic development is essentially based on self-financing of investment cycle. The efficient use of energy resources and raw materials could rise by increasing the renewal of fixed capital, which is meaning also a shift to a higher technological level. From this correlation is...

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 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 structure of a national economy is generally correlated with the stage of economic development. In economic history, it was demonstrated a trend from a first stage when agriculture predominated to last stage when the sector of services is the largest. In this context, the complex...
