Abstract
Investors dislike ambiguous news when its quality is hard to judge, and then make trading decisions based on a worst-case belief of information quality. We provide empirical evidence on the cross-sectional pricing implications of ambiguity-averse theory induced by poor information quality. Using news-based monetary policy uncertainty (MPU) index in China, we find that stocks with high MPU exposure earn lower average returns compared to stocks with low MPU exposure. This negative MPU effect is asymmetric and stronger in periods of bad MPU news than in periods of good MPU news. The premium for bearing MPU is not common risk compensation, nor is it explained by the well-known firm characteristics.
期刊介绍:
Research in International Business and Finance (RIBAF) seeks to consolidate its position as a premier scholarly vehicle of academic finance. The Journal publishes high quality, insightful, well-written papers that explore current and new issues in international finance. Papers that foster dialogue, innovation, and intellectual risk-taking in financial studies; as well as shed light on the interaction between finance and broader societal concerns are particularly appreciated. The Journal welcomes submissions that seek to expand the boundaries of academic finance and otherwise challenge the discipline. Papers studying finance using a variety of methodologies; as well as interdisciplinary studies will be considered for publication. Papers that examine topical issues using extensive international data sets are welcome. Single-country studies can also be considered for publication provided that they develop novel methodological and theoretical approaches or fall within the Journal''s priority themes. It is especially important that single-country studies communicate to the reader why the particular chosen country is especially relevant to the issue being investigated. [...] The scope of topics that are most interesting to RIBAF readers include the following: -Financial markets and institutions -Financial practices and sustainability -The impact of national culture on finance -The impact of formal and informal institutions on finance -Privatizations, public financing, and nonprofit issues in finance -Interdisciplinary financial studies -Finance and international development -International financial crises and regulation -Financialization studies -International financial integration and architecture -Behavioral aspects in finance -Consumer finance -Methodologies and conceptualization issues related to finance
