The paper concerns the measurement of the dependence between economic spatial and also spatio-temporal processes at various levels of data aggregation. The considerations refer to the investigations confirming efficiency of the so-called quasi-congruent spatial model as a tool of the measurement...

This paper develops a criterion of opportunity equalization, that is consistent with theoretical views of equality of opportunity. Our analysis rests on the characterization of inequality of opportunity as a situation where some groups in society enjoy an illegitimate advantage. In this context,...

This paper develops a criterion to assess equalization of opportunity that is consistent with theoretical views of equality of opportunity. We characterize inequality of opportunity as a situation where some groups in society enjoy an illegitimate advantage. In this context, equalization of...

The article presents the problem of the application of the spatial weigh matrix based on economic distance in spatial analysis of the unemployment rate. The spatial weight matrix expresses potential spatial interactions between the re-searched areas and forms a basis for the instruments applied...

The article discusses an essential problem of spatial econometrics which is the construction of a spatial weight matrix. This matrix expresses potential spatial interactions between the researched areas and forms the basis for spatial analyses. The objective of the paper was to consider various...

This paper investigates GCC countries' trade integration. The gravity equation is estimated using Panel Zero-Inflated Negative Binomial specification and COMTRADE aggregate and disaggregated flows. Results confirm GCC countries' integration deficit on exports side, while being integrated to some...

This paper investigates the effects of horizontal acquisitions on the productive efficiency of target firms in the 1990s. Using French manufacturing firm-level data, we implement appropriate difference-in-difference estimation techniques associated to a matching propensity score procedure. We...
