In recent years, the world economy has also witnessed the rise in economic and policy uncertainty due to Brexit, the deceleration of growth in the Chinese economy, the Trump administration's trade policy. There are now more massive uncertainty shocks of the COVID-19 in every aspect of the economic system. Both developed and developing economies are experiencing risks and uncertainties due to the significant effects of the COVID-19. This Research Topic aims to understand the consequences of uncertainty shocks related to the COVID-19. The main objective of this Research Topic is to try to provide different aspects and consequences of the COVID-19 pandemic. The Research Topic contains 26 papers.

This Research Topic includes several papers on the determinants and the outcomes of the COVID-19 pandemic. Gorain et al. discuss the fighting strategies against the COVID-19 pandemic at the global level. Meng observe the different country clusters for the measures of the COVID-19 outcomes in the G20 economies. Jiang et al. find that the health levels in the United States and the United Kingdom are not significantly affected by the COVID-19-related shocks. Zhai et al. observe that conflicts are the main driver of the mortality risk of the COVID-19 in 120 countries. Wang et al. show that the COVID-19 pandemic causes geopolitical risks in 18 emerging economies. Fang et al. use the trend analysis data from the Baidu search engine to predict the pattern of the COVID-19 pandemic in China.

The Research Topic also covers several papers on the economic effects of the COVID-19 pandemic. Wu finds that pandemics-related uncertainty, measured by the Pandemic Uncertainty Index, negatively affects household consumption in 138 countries. Li and Liang observe that uncertainties related to the COVID-19, measured by the World Pandemic Uncertainty Indices, are positively related to fiscal support in 129 countries. Li Y. et al. discuss the efficiency of monetary policy implications in Brazil, China, India, Japan, and the United Kingdom during the pandemics. Chen, Lau et al. show that the pandemics-related uncertainty is positively related to the income inequality in 34 OECD economies, but the impact is negative in 107 non-OECD countries. Regarding China, where the COVID-19 pandemic first hit the economy, Shen et al. observe the significant divergence of the trend of disposable income across the Chinese cities during the COVID-19 pandemic. Li J. et al. also predict that the monthly income of migrant workers in China will be reduced due to the COVID-19 pandemic.

This Research Topic also includes several papers on the effects of the COVID-19 pandemic on financial markets. Liu and Guo show the positive impact of inclusive finance on public health in the Chinese regions during the pandemics. Pan et al. examine the possible determinants of tourism stock returns in China during the COVID-19 era. Ye et al. compare different models to estimate the equity performances of the health insurance companies in China during the COVID-19 pandemic. Meng et al. observe that the confirmed cases cause public searches for the COVID-19 tests, which also causes fluctuations in the infectious disease equity market volatility tracker in the United States. Wang et al. also find that the United States Dollar (USD) and the volatility indices (VIX) decrease the S&P 500 equity returns during the COVID-19 crisis. However, the newspaper-based infectious disease equity market volatility tracker is positively associated with stock market returns in the United States.

Su and Zhou use the case of Chongqing (China) to discuss the ecological livability of tourist towns with the outbreak of the COVID-19 pandemic. Limei and Wei take online travel booked by consumers as an example and consider Guangzhou Baiyun International Airport (China) data to analyze the influence of reviewers' creditworthiness on consumer purchase intention. Determinants of purchase intention provide several implications to be used during the COVID-19 pandemic.
