This paper explores the influence of the ESG disclosure regulation (government corporate ESG disclosure and non-government corporate ESG disclosure) on the ranking in 50 largest economies. Applying various statistical methods and techniques, including both parametrical (Student’s t-test, ANOVA analysis) and non-parametrical (Mann-Whitney U test) tests, simple average analysis, OLS with dummy variables method and multiple linear regression analysis, as well as correlation analysis and Granger causality test, several hypotheses are tested. The hypotheses stipulate whether or not ESG disclosure regulation differs in developed and emerging countries and whether or not ESG disclosure regulation influences the country’s SDGI ranking, as well as the ranking of the country among 50 largest economies. According to the results, the differences in ESG disclosure regulation are statistically significant in developed and emerging countries. The level of ESG disclosure compliance is higher in developed countries. ESG disclosure regulation influences the position of the country in SDGI and 50 largest economies rankings. The more country complies with ESG disclosure criteria, the better position in rankings is. Incorporation of ESG criteria is an important evolutionary step in economic development of the country. It allows increasing position of the country in 50 largest economies and SDGI ranking. Thus, ESG disclosure regulation is vital for the development of the country in the modern world.

Corporate social responsibility, disclosed in sustainability reporting, influences the financial performance of companies. As a result, traditional stock market indices (TI) are expanded with the social responsible stock market indices (SRI). The aim of this study was to establish whether there are any differences in the behavior of the TI and SRI. To do this, the authors analyzed their efficiency. They used R/S analysis to calculate the Hurst exponent as a measure of persistence (long-term memory property). The presence of persistence was evidence in favor of less efficiency. According to empirical results, SRI has lower efficiency, in particular the Dow Jones Sustainability Index. Lower efficiency was also observed in the emerging markets with a responsible investment segment, compared to the traditional stock market indices. Further standardization and a common methodological approach to corporate sustainability reporting disclosure are proposed.

This paper investigates persistence in financial time series at three different frequencies (daily, weekly and monthly). The analysis is carried out for various financial markets (stock markets, FOREX, commodity markets) over the period from 2000 to 2016 using two different long memory approaches (R/S analysis and fractional integration) for robustness purposes. The results indicate that persistence is higher at lower frequencies, for both returns and their volatility. This is true of the stock markets (both developed and emerging) and partially of the FOREX and commodity markets examined. Such evidence against the random walk behaviour implies predictability and is inconsistent with the Efficient Market Hypothesis (EMH), since abnormal profits can be made using trading strategies based on trend analysis.
