Early, the convergence theory was suggestively expressed in the Solow model. This can be shown in line with the fact that while economic development is advancing (expressed by the income per capita growth), on long run there is a general convergence process among countries. Generally, empirical...

There are evidences that the actual global crisis affected the convergence process in EU. Generally, just new adhered countries were more affected by the actual crisis. Today all forecasts are suffering by uncertainty. Last time, economists, with their methods and models, are invoked for actual...

The purpose of this study is to investigate the relation between regional convergence inside of countries in EU and overall economic growth, and, based on it, to establish some relevant behavioural regimes. As data sources we are using the available dataset NUTS 2 from EUROSAT for the period...

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...
