F65 - Economic Impacts of Globalization: FinanceNávrat zpět

The United Nations Sustainable Development Goals (SDGs) emphasize the importance of energy by making affordable and clean fuel access the focus of Goal 7. Energy poverty is a widespread issue globally, particularly in developing countries. Thus, this investigation inspects the drivers of energy poverty in Brazil using data from 1997Q1 to 2022Q4. The study introduces the wavelet Zivot-Andrews (WZA) unit root test, which modifies the traditional Zivot-Andrews (ZA) test by incorporating wavelet analysis, allowing decomposition of the time series into different time scales (short-term, medium-term and long-term). This enables the WZA test to capture structural breaks and unit roots more effectively across various time scales. In addition, the study employs wavelet quantile-on-quantile regression. The results show that across all quantiles and time scales, an increase in financial globalization and economic policy uncertainty increases energy poverty. The study also shows that female political participation increases energy poverty in the short and long term. In contrast, in the medium term and across all quantiles, female political participation decreases energy poverty. Lastly, an increase in financial development decreases energy poverty across all quantiles and periods. Based on these findings, policies are suggested.

Due to progressing globalisation and deepening integration of global financial markets, the topic of relations between individual markets has got into the centre of attention of many economists. Especially on the stock markets, we can observe a tendency of the more developed markets to affect developments on the less developed markets. This is also valid for stock markets of the Central and Eastern European (CEE) countries, the V4 countries included. In the case of returns and volatilities of the V4 stock markets, it is possible to expect a strong influence of the German stock market. We follow this influence using the Granger causality. Our analysis shows that in the period 1999-2018, the German DAX stock index was Granger-causing the development of the Czech (PX), Hungarian (BUX) and Polish (WIG 20) stock indices, while this relation was not confirmed for DAX and the Slovak stock index SAX. However, the analysis of two sub-periods (1999-2007 and 2010-2018) shows slightly different results.
