A High-Frequency Measure of Chinese Monetary Policy Shocks
We develop a daily measure of Chinese monetary policy shocks that incorporates both quantity and interest rate-based policy changes. Our shock measure serves as a sufficient statistic tailored to the Chinese market, addressing the common issue in emerging markets of lacking a key proxy for monetary policy stance due to multi-dimensional objectives and complex toolkits. We validate its effectiveness in capturing unexpected monetary policy changes in China. Shedding light on monetary policy transmission, our shock series reveals that Chinese monetary policy significantly affects the equity and credit risk of non-financial firms and shifts real macroeconomic variables.

The Incident-Driven Green Products
We employ the ChatGPT model to identify green products in the US product markets. Approximately 3.7% of US product announcements from 2002 to 2022 qualify as green products. Using a stacked Difference-in-Differences approach, we find that firms involved in severe environmental incidents launch 40% more green products within two years following the incidents. These incident-driven green products are notably novel, supported by high-quality green patents, and result in substantial environmental improvements for both producers and consumers. In contrast, green products introduced without the impetus of environmental incidents do not demonstrate meaningful environmental gains and often raise concerns of greenwashing.

Gold is a Hedging Asset
While industry investors commonly view gold as a hedging asset, academic studies often find the opposite. We show that gold is a prominent hedging asset via three different approaches: a state-space model, predictive regressions, and principal component analyses. We find that, ceteris paribus, gold prices increase with expected stock market return μₜ and expected dividend growth rate gₜ. In bad times, μₜ rises while gₜ declines. It thus may seem that gold prices fall in bad times and that gold prices insignificantly or even negatively predict stock returns. However, after addressing the omitted-variable-bias introduced by gₜ, we find that gold prices significantly and positively predict stock returns.
