Central European Journal of Economic Modelling and Econometrics

Opis

The Central European Journal of Economic Modelling and Econometrics (CEJEME) is a quarterly international journal. It aims to publish articles focusing on mathematical or statistical models in economic sciences. Papers covering the application of existing econometric techniques to a wide variety of problems in economics, in particular in macroeconomics and finance are welcome. Advanced empirical studies devoted to modelling and forecasting of Central and Eastern European economies are of particular interest. Any rigorous methods of statistical inference can be used and articles representing Bayesian econometrics are decidedly within the range of the Journal's interests.

1 Consensus Seeking: How Juror Exclusion Shapes Strategic Incentives in the Borda Count

Central European Journal of Economic Modelling and Econometrics | 2025 | No 2 | 87-110 | DOI: 10.24425/cejeme.2025.156672

Abstrakt

We examine incentives and strategic behavior in a voting game using a new modification of the Borda count in which the score of the juror with the largest deviation from the mean score vector is excluded. We show that introducing juror exclusion has a strong effect on incentives. In particular, it motivates jurors to align with the mean. When jurors' preferences are closely aligned - that is, when the subjective component of the evaluation is small relative to the objective one - excluding the outlier's score is likely to reduce manipulation. However, when jurors' preferences differ significantly, the method may actually increase misreporting compared to the standard Borda count without juror exclusion.

2 Oil Rents and Income Inequality: The Moderating Role of Institutional Quality in Oil-Rich Developing Countries

Kahina Mehidi , Kamal Oukaci

Central European Journal of Economic Modelling and Econometrics | 2025 | No 2 | 111-130 | DOI: 10.24425/cejeme.2025.156673

Słowa kluczowe: oil rent income inequality institutional quality panel data

Pobierz PDF Pobierz RIS Pobierz Bibtex

Abstrakt

The purpose of this study is to analyze the impact of oil rent on income inequalities. To this end, we selected a sample of 22 oil-rich developing countries and Norway as a benchmark country. The methodology employed in this work involves the use of a dynamic panel data specification over the period 2000-2022. The econometric results show the existence of a non-linear (inverted U-shaped) relationship between oil rent and inequality. Specifically, oil rent increases inequality in the short term. This effect diminishes as oil revenues increase. Another important finding is that the reduction of income inequality due to the increase in oil rent is closely related to the quality of the institutional framework.

3 A Note on Some Extensions of the Matrix Angular Central Gaussian Distribution

Abstrakt

In this paper, we extend the concept of a matrix angular central Gaussian (MACG) distribution to the complex domain. First, we consider a normally distributed random complex matrix (Z) and demonstrate that its orientation exhibits a complex MACG (CMACG) distribution. We then discuss the distribution of the orientation of the linear transformation of the random matrix, the orientation of which has a CMACG distribution. Finally, we examine the family of distributions that leads to the CMACG distribution.
