Do words hurt more than actions? The impact of trade tensions on financial markets
用机器学习量化中美贸易紧张程度，发现贸易紧张主要冲击中国和新兴市场股市及汇率，而美国市场除涉华企业外基本不受影响。
Summary We use machine learning techniques to quantify trade tensions between the United States and China. Our measure matches well‐known events in the US‐China trade dispute and is exogenous to the developments on global financial markets. Local projections show that rising trade tensions leave US markets largely unaffected, except for firms that are more exposed to China, while negatively impacting stock market indices and exchange rates in China and emerging markets. We complement these findings with additional evidence suggesting that the US‐China trade tensions have been interpreted as a negative demand shock for the Chinese economy rather than as a global risk shock.
