Information salience,investor sentiment,and stock returns: The case of British soccer betting

Soccer clubs listed on the London Stock Exchange provide a unique way of testing stock price reactions to different types of news. For each firm, two pieces of information are released on a weekly basis: experts' expectations about game outcomes through the betting odds, and the game outcomes themselves. The stock market reacts strongly to news about game results, generating significant abnormal returns and trading volumes. We find evidence that the abnormal returns for the winning teams do not reflect rational expectations but are high due to overreactions induced by investor sentiment. This is not the case for losing teams. There is no market reaction to the release of new betting information although these betting odds are excellent predictors of the game outcomes. The discrepancy between the strong market reaction to game results and the lack of reaction to betting odds may not only be the result from overreaction to game results but also from the lack of informational content or information salience of the betting information. Therefore, we also examine whether betting information can be used to predict short-run stock returns subsequent to the games. We reach mixed results: we conclude that investors ignore some non-salient public information such as betting odds, and betting information predicts a stock price overreaction to game results which is influenced by investors' mood (especially when the teams are strongly expected to win).     

Addendum to L. Lauwers and L. Van Liedekerke, “Ultraproducts and aggregation” [J. Math. Econ. 24 (3) (1995) 217–237]

This addendum fills a minor gap in the key lemma of a paper by Lauwers and Van Liedekerke [Lauwers, L., Van Liedekerke, L., 1995. J. Math. Econ. 24 (3), 217–237].     

Retweet if you please! Do news factors explain engagement?

Stakeholders’ engagement with corporate messages is crucial for companies that want to increase their social media coverage. However, our understanding of the content-related factors that drive stakeholders’ engagement is still poor. Drawing from the literature on news selection and distribution, this paper explores whether the relevant news values that are already found in corporate messages could also explain greater engagement in social media. In particular, six news factors were examined in a sample of 2331 tweets that were posted by the Euro Stoxx 50 companies. The results show that four news factors (in particular, Prominence, Entertainment, Immediacy, and to a lesser extent Human interest) play a role in the drive of content sharing through retweets and favorites. Additionally, the inclusion of hashtags and media content helps increase retweets and favorites. Finally, we observe differences among industries. In particular, firms operating in business-to-business industries obtain less reach through sharing. The implications of these results are relevant for social media strategists as they suggest avenues to increase followers’ engagement with company-produced content.     

A century of corporate takeovers: What have we learned and where do we stand?

This paper reviews the vast academic literature on the market for corporate control. Our main focus is the cyclical wave pattern that this market exhibits. We address the following questions: Why do we observe recurring surges and downfalls in M&A activity? Why do managers herd in their takeover decisions? Is takeover activity fuelled by capital market developments? Does a transfer of control generate shareholder gains and do such gains differ across takeover waves? What caused the formation of conglomerate firms in the wave of the 1960s and their de-conglomeration in the 1980s and 1990s? And, why do we observe time- and country-clustering of hostile takeover activity? We find that the patterns of takeover activity and their profitability vary significantly across takeover waves. Despite such diversity, all waves still have some common factors: they are preceded by technological or industrial shocks, and occur in a positive economic and political environment, amidst rapid credit expansion and stock market booms. Takeovers towards the end of each wave are usually driven by non-rational, frequently self-interested managerial decision-making.     

More than energy transformations: a historical transition from organic to industrialized farm systems in a Mediterranean village (Les Oluges,Catalonia, 1860–1959–1999)

The analysis of energy efficiency of agroecosystems from a sociometabolic perspective is a useful way to assess the sustainability of farm systems. In this paper we examine the transition of a Mediterranean agroecosystem from an organic farm system in the mid nineteenth century to an industrialized one at the end of the twentieth century by means of the technologies and ideology of the Green Revolution. Given that many of the world’s agricultural systems have experienced, or are currently experiencing this transformation, our results are relevant for building more sustainable agricultural systems in future. Our results highlight the relevance of livestock density, and the flows of biomass reused and unharvested biomass as key elements affecting the sustainability of the agroecosystem not only from a socioeconomic perspective, but also from an agroecological point of view. Additionally, from a biocultural perspective our investigation sustains the relevance of the study of traditional farm systems for the development of a sustainable agriculture.     

Entrepreneurial orientation in family firms: the moderating role of technological intensity and performance

This paper examines how socio-emotional factors can influence family firms’ commitment to entrepreneurially- oriented activities, and how their level of commitment is moderated by the technological intensity of the sector and firm performance. We find that, while family firms are less entrepreneurially-oriented than non-family firms, this gap closes with increasing technological intensity of the sector. We find no evidence, however, to suggest any change in entrepreneurial orientation in family firms resulting from a drop in firm performance.
