Summary

We have developed a China Vulnerability Sentiment Index using Big Data

The CVSI index allows us to track the 4 different vulnerability components: SOEs, Shadow Banking, Housing Bubble & FX speculative Robustness Check: “prior” inclusion of Sentiment Indicators is “Posterior” confirmed through Bayesian Model Averaging (BMA) No Systematic Bias between English & Chinese Sentiment in Local and foreign media but transitory deviations can affect market sentiment

Sentiment & Economics: References

Theoretical Literature • Pigou (1927): business cycle fluctuations are driven by expectations and entrepreneurs’ errors of optimism and pessimism are crucial determinants of these fluctuations • Keynes (1936) highlighted the importance of changes in expectations that are not necessarily driven by rational probabilistic calculations, but by “animal spirits” • Shiller (2017) shows “narratives” can explain aggregate fluctuations though epidemic models.

Empirical Literature • Angeletos, Collard and Dellas (2015) find that sentiment shocks account for around 1/2of GDP variance and 1/3 of the nominal interest rate variance at business-cycle frequencies. • Barsky and Sims (2012) found that this informational component forms the main link between sentiment and future activity in international business cycles. • Shapiro, Sudhoff, and Wilson (2017) show how the news sentiment measures outperform the University of Michigan confidence index Tracking Chinese Vulnerability in Real Time.
