This paper is a substantially revised version of our earlier working paper, "Truth and Robustness in Cross-country Growth Regressions." The most important revisions concern the handling of missing observations in the cross-country data set. In the earlier paper, these had been handled through...

The work of Levine and Renelt (1992) and Sala-i-Martin (1997a, b) which attempted to test the robustness of various determinants of growth rates of per capita GDP among countries using two variants of Edward Leamer's extreme-bounds analysis is reexamined. In a realistic Monte Carlo experiment in...

In this study a composite indicator is constructed to rank macroeconomic performance of countries and a separate composite indicator is constructed to rank countries by inequality using the TOPSIS methodology of Multiple Criteria Decision-Making Analysis. The intuitive idea of TOPSIS is to...

The paper discusses the socio-economic challenges and their systemic features in the conditions of the COVID-19 pandemic as in the context of global as individual countries. The significant effect, such as increasing socio-economic uncertainty is analyzed. The research shows that in the...

The main purpose of the study presented in the paper is to reveal some important macroeconomic and cultural features of the economic crisis caused by the COVID-19 pandemic. The study used the methods of system analysis and modeling. Since the source of the crisis was not the economy but the...

The research perspective of gold is either as a commodity or as a financial asset in most previous research. This paper initially examines the double nature of the price of gold both as a commodity and money from 1969 to 2014 by a statistics model, namely the Ensemble Empirical Mode...

This paper proposes a composite indicator designed to summarise in a single statistic a variety of different facets of macroeconomic performance and assesses relative performances of countries with respect to six macroeconomic variables, viz., the growth rate of real GDP, real per capita GDP,...

This paper initially analyzes the constitution of gold price by Ensemble Empirical Mode Decomposition (EEMD) with a data span of 1969-2014. We decompose and categorize the change of the gold price by time frequency into three aspects: high frequency portion, low frequency portion and trend...
