This study explores the conditional version of the capital asset pricing model on sentiment to provide a behavioural intuition behind the value premium and market mispricing. We find betas (β) and the market risk premium to vary over time across different sentiment indices and portfolios. More importantly, the state β derived from this sentiment-scaled model provides a behavioural explanation of the value premium and a set of anomalies driven by mispricing. Different from the static β–return relation that gives a flat security market line, we document upward security market lines when plotting portfolio returns against their state βs and portfolios with higher state βs earn higher returns. 相似文献
This study investigates the effect of international coproduction on the performance of cultural products in the global markets. As a result of institutional barriers and cultural distances, coproduction, which allows a foreign producer to partner with the local firms, has emerged as a way of increasing cultural product performance in the global markets. Using the data on the Chinese movie market from 2012 to 2018, the authors find that international coproduction can promote movie performance and that the coproduction effect is mainly explained by the institutional variables. They further examine the heterogeneous effects and find that coproduction effect is stronger for culturally sensitive movies, and that the magnitude of the coproduction effect increases with the level of cooperation. They also confirm that the results are robust to different measurements of performance.
This paper analyzes productivity and efficiency of English professional football clubs from 1981–1982 to 2010–2011, using a random coefficient stochastic distance frontier (SDF) model. Our Bayes factor analysis indicates that this model is strongly favored over the commonly used fixed coefficient SDF model. Our empirical results show that clubs in our sample operate at different levels of technical efficiency and technical change. Our further analysis using ordered logistic regression suggests that technical efficiency is more important than technical change in predicting whether clubs in our sample are promoted or relegated. 相似文献
