ESG, liquidity, and stock returns
Full text linkWe examine the effect of environment, social, and governance (ESG) score on stock returns in the United Kingdom (UK). Consistent with Hong and Kacperczyk (2009), Bolton and Kacperczyk (2021), and Pedersen et al. (2021), firms with lower ESG earn higher returns than those with higher ESG. The environment and social premiums are more pronounced than the ESG premium. To understand the premium, we show that the ESG premium is significant for low liquidity securities but not for high liquidity securities, which suggests that ESG is likely associated with stock liquidity
Financial constraints, stock liquidity, and stock returns
Full text linkThis paper examines stock liquidity in explaining the mixed relations between financial constraints and stock returns and the pricing of stock liquidity across financially constrained and unconstrained firms. We find a negative relation in liquid portfolios and a positive relation in illiquid portfolios. Financially constrained firms have higher liquidity risk and earn a higher illiquidity premium than unconstrained firms. Financial constraints cannot be independently priced in stock returns and can only be priced in conjunction with stock liquidity in bad economic times. Stock liquidity is independently priced for financially constrained firms or in good times, but not for unconstrained firms
Investor sentiment, limited arbitrage and the cash holding effect
Full text linkWe examine the investor sentiment and limits-to-arbitrage explanations for the positive cross-sectional relation between cash holdings and future stock returns. Consistent with the investor sentiment hypothesis, we find that the cash holding effect is significant when sentiment is low, and it is insignificant when sentiment is high. In addition, the cash holding effect is strong among stocks with high transaction costs, high short selling costs, and large idiosyncratic volatility, indicating that arbitrage on the cash holding effect is costly and risky. In line with the limits-to-arbitrage hypothesis, high costs and risk prevent rational investors from exploiting the cash holding effect
Increase in cash holdings of U.S. firms: The role of healthcare and technology industries
Full text link© 2020 Elsevier Inc. We examine whether the high cash ratio and the secular increase in cash holdings of U.S. firms are driven by healthcare and technology industries. We find that these two industries have significantly increased their cash holdings from 1980 to 2015. It is only in these two industries that firms with riskier cash flow, financially constrained firms, R&D firms, low-efficiency firms, and firms with low institutional ownership and high board size dramatically increase their cash holdings. Similar firms in other industries do not substantially accumulate cash reserves. The explanatory powers of firm characteristics, industry characteristics, and industry competition on cash holdings in healthcare and technology industries are stronger than in other industries. Moreover, we find a causal effect of the 2008 financial crisis on the difference in cash holdings between healthcare and technology industries, and other industries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Liquidity risk and the beta premium
No full textAs opposed to the "low beta low risk'' convention, we show that low beta stocks are illiquid and exposed to high liquidity risk. After adjusting for liquidity risk, low beta stocks no longer outperform high beta stocks. Although investors who ``bet against beta'' earn a significant beta premium under the Fama--French three- or five-factor models, this strategy fails to generate any significant returns when liquidity risk is accounted for. Our work helps understand the beta premium from a new liquidity-risk perspective, and draws useful implications for both fund and corporate managers
