We develop a new method to measure economic policy uncertainty and test its dynamic relationship with output, investment, and employment. We find that, since 2008, economic policy uncertainty in the United States has been at a level approximately two tim
We are pleased to host the Energy-Related Uncertainty Indexes (EUI) created by Tam Hoang-Nhat Dang, Canh Phuc Nguyen, Gabriel S. Lee, Binh Quang Nguyen and Thuy Thu Le for their article on "Measuring the Energy-Related Uncertainty Index" in Energy Economics, 2023....
ensemble learning techniques [ensemble linear regression (LM), random forest], as well as two gradient boosting techniques [Gradient Boosting Decision Tree and Extreme Gradient Boosting (XGBoost)] to scrutinize the possibilities of enhancing the predictive accuracy of Economic Policy Uncertainty (EPU) ...
This study aims to test the symmetric and asymmetric impact of economic policy uncertainty (EPU) on economic growth for the time period 2011M1–2020M5
The first and most flexible component quantifies newspaper coverage of policy-related economic uncertainty.

The impact of policy uncertainty on China's economic activity has received considerable attention. To appraise the role of economic policy uncertainty (EPU) in China's economic downturns, we estimate the predictive distribution of China's GDP growth as a function of EPU from 1996Q1 to 2020Q2, ...
We examine the impact of government economic policy uncertainty (GEPU) on corporate innovation and identify a cost-of-capital transmission channel. We find that GEPU increases firms’ cost of capital, which translates into lower innovation. As economic policy uncertainty rises, firms with more exposur...
Moreover, investor sentiment plays a mediation role between economic policy uncertainty and voluntary disclosure. Furthermore, for state-owned, high bankruptcy risk, and low growth firms, the positive effect of EPU on the timeliness and sufficiency of voluntary disclosure becomes larger....
As the continuous changes in environmental regulations have a non-negligible impact on the innovation activities of micro subjects, and economic policy uncertainty has become one of the important influencing factors to be considered in the development of enterprises. Therefore, based on the panel data...
