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...

Whether foreign direct investment (FDI) is beneficial to host country growth or not is a question debated since a long time. This paper provides a survey of the literature on FDI, export and growth, and empirically investigates the causal relationship between economic growth, export and FDI for...

In this article, we used a stochastic frontier model to estimate the cost efficiency of cooperative banks and savings banks from nine countries over the period 2005 to 2011. In addition, we analyzed the influence of certain variables that quantify the risk and performance of cooperative banks...

With the collapse of the socialist system in Eastern Europe and the advancement of the European Union integration process of the formerly communist countries, many of which are increasingly likely to join the single European market in the foreseeable future, the informal sector in transitional...

The current paper attempts to describe the labor market parameter dynamics using a different method, namely the semi-Markovian processes. This method allows for the labor market study without the large fluctuations that occurred at a certain moment in time impinging upon the results of the...

In the last years it seemed that the Romanian economy leading up to access to the EU was going to enter a new stage, evolving more and more in line with the standard theory. Based on more accurate statistical data for the last years, we try to verify some hypotheses used in the standard economic...

This article presents alternative scenarios of macroeconomic dynamics for Romania. The author starts by presenting the structure of the model used for simulations. Two scenarios are developed for the 2003-2010 period. The first one, the desirable scenario, embodies performances envisaged in the...

Risk has become an important variable in many areas of research. Measures of risk have been included in research on corporate products diversification, international geographic diversification, vertical integration, business strategy and industry characteristics, organizational process and...

We develop Dobrescu’s ideas (2011, 2013) to discover the main characteristics of an economic or social system. Many classifications of models, based on different dissimilarity measures, were taken into consideration. Also a practical example, which analyzes the relations among some indicators...

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...
