Bayesian learning provides the core concept of processing noisy information. In standard Bayesian frameworks, assessing the price impact of information requires perfect knowledge of news' precision. In practice, however, precision is rarely dis- closed. Therefore, we extend standard Bayesian...

Using the introduction of high-speed rail (HSR) as an exogenous shock to costs of information acquisition, we show that reductions in information-acquisition costs lead to (i) a significant increase in information production, evidenced by a higher frequency of analysts visiting portfolio firms,...

Using the introduction of high-speed rail as exogenous shocks to costs of information acquisition, we show that reductions in information-acquisition costs lead to a significant increase in information production and improvement in output quality, evidenced by higher frequency of analysts...
