Indirect news coverage and economic policy uncertainty
利用新闻的语义指纹衡量各国新闻强度，通过DCC-GARCH模型发现新闻强度与经济不确定性正相关，且影响不确定性与通胀、产出增长的相关性。
This paper uses semantic fingerprints of news to measure news intensity for countries. Estimation results from DCC-GARCH models show that correlations between news intensity and economic uncertainty are mostly positive throughout time. The more relevant news about a country are published, the higher is the economic uncertainty in that country. News intensity also has a negative impact on correlations between uncertainty and inflation, and a positive impact on correlations between uncertainty and output growth.
