内容简介:

How do global and domestic investors process institutional signals in emerging markets? We construct a high-frequency measure of marketization surprises by comparing China's refined-oil price adjustments with formula-implied benchmarks, yielding an objective indicator of reform intensity from 2013 to 2025. Using event-study approaches with Kalman-filter decomposition, we document three new facts. First, observable marketization surprises generate opposite responses across markets: a 1% marketization surprise triggers $3 billion in equity outflows and $1 billion in bond outflows from international investors, while domestic stock-index futures prices rise (e.g., CSI 300 by 0.06%). Second, latent institutional signals exhibit distinct information-processing structures: international flows load on two unobservable factors---a bond-dominant and a passive-dominant factor---whereas domestic markets load on a single factor, with near-zero cross-market correlation. Third, international responses amplify over quarterly horizons, while domestic effects dissipate immediately. Together, these results uncover persistent cross-market segmentation in how institutional reforms are interpreted and highlight the role of heterogeneous information processing in emerging-market asset pricing.
