Measuring Geopolitical Risk

Dario Caldara, Matteo Iacoviello

Summary: This paper presents a news-based measure of adverse geopolitical events and their risks. The geopolitical risk index is particularly high during significant historical events such as world wars, the Korean War, the Cuban Missile Crisis, and after 9/11. Higher geopolitical risk leads to lower investment and employment, as well as increased probability of disasters and larger downside risks. This risk is driven by both the threat and occurrence of adverse geopolitical events. Industry- and firm-level indicators also show that investment declines more in industries exposed to geopolitical risk, and higher firm-level geopolitical risk is associated with lower investment.

Aggregate Confusion: The Divergence of ESG Ratings*

Florian Berg, Julian F. Kolbel, Roberto Rigobon

Summary: This paper investigates the divergence in ESG ratings among six prominent rating agencies.

The analysis also identifies a rater effect where the overall view of a firm influences the measurement of specific categories. The findings emphasize the importance of understanding the data generation process underlying ESG ratings.

The impact of clean energy consumption on economic growth in China: Is environmental regulation a curse or a blessing?

En-Ze Wang, Chien-Chiang Lee

Summary: Using a finite mixture model to estimate the production function, this research examines the interrelationships among environmental regulation, clean energy consumption, and economic growth. The findings show that environmental regulation enhances the positive impact of clean energy consumption on economic growth, while ignoring measurement error and misspecifying the production function can bias estimation results. Moreover, traditional frameworks may underestimate the significance of clean energy consumption's impact on economic growth compared to accounting for heterogeneity and using clean energy production data.

How does fiscal policy uncertainty affect corporate innovation investment? Evidence from China's new energy industry

Huwei Wen, Chien-Chiang Lee, Fengxiu Zhou

Summary: This study examines the relationship between fiscal policy uncertainty and corporate innovation investment in Chinese A-share listed companies in the new energy industry from 2007 to 2019. The findings suggest that fiscal policy uncertainty significantly reduces innovation investment, largely due to the decline in government support incentives. Product market competition, however, mitigates the adverse effects of fiscal policy uncertainty on innovation investment. Bank credit constraint serves as the mechanism through which fiscal policy uncertainty restrains innovation investment.
