The paper interprets the dynamics of the underground economy in a transforming environment by highlighting the role of institutions in enforcing the rules of the game and the phenomenon of strain. A basic idea is that the underground economy emerges as a means for the system to diffuse its...

In this paper we classify competitive markets using a new form of normalized Herfindahl index and the degree of dominance of the leader. For this purpose we use the notion of copula, which connects two or more random variables with given marginals. The parameters of the two marginals (which are...

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...

Having in view the three main methods for the estimation of the informal economy's size, the study focuses in the first part on data and methodological problems, trying at the same time to outline a few behavioral aspects by using only simple simulation models. Thus, based on a 288-sample and...

Using a Romanian household survey, we analyse the structure of households’ income by sources: main job, secondary job, and informal activities. We began the study by focusing on data and methodological problems, certain clarifications being necessary. Then we estimated the size of informal...

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...

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...

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...

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...

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...
