We show that a combined bet at the bookmaker and at the bet exchange market yields a guaranteed positive return in 19.2% of the matches in the top five European soccer leagues. Moreover, we find that all considered bookmakers frequently offer arbitrage positions, and that they experience, on average, negative margins from these postings. Our findings indicate that bookmakers set prices not only by optimizing over a particular bet, but also by taking the future trading behaviour of their customers into account. We discuss the implications for the literature on the relationship between betting market structure and informational efficiency.
Firms generate new knowledge that leads to innovations by recombining existing knowledge sources. A successful recombination depends on both the availability of a knowledge stock (human capital pool) that contains innovation-relevant knowledge and the regulation of the knowledge flow through the application of human resource management practices. However, while human resource theory expects complementarities between both the human capital pool and the human resource management system it does not explicitly address their implications for knowledge exchange. Moreover, empirical approaches neglect the complexity of complementarities between the two factors. This study analyzes complementarities within and between the human capital pool and the human resource management system and shows their implications for knowledge exchange. We empirically analyze these complementarities by applying fsQCA to identify taxonomies that explain superior innovation performance. We show that firms can achieve superior innovation performance through multiple and complex pathways. Our results show four taxonomies that substantially differ in terms of human capital diversity, application of human resource management practices and the environmental dynamism of the firm.
The YouTube platform reduces fixed entry costs for local artists but also lowers the cost of access to international superstars. The net effect is an empirical question. We study the effect of YouTube on the market for music, focusing on converging tastes for international hits. We consider Austria and Germany, which share a common culture and technological development but differ in access to music videos on YouTube. Exploiting a contract dispute that has blocked official music videos in Germany since 2009, we find that YouTube increases the number of US hits on European charts. We further find evidence that YouTube speeds the hit-making cycle and brings more unique titles to top charts. Although the superstar effect dominates, the magnitude of estimated effects are modest, suggesting that YouTube will not drive out the market for local music.
Existing evidence shows that decision-makers’ social ties to internal co-workers can lead to reduced firm performance. In this paper, we show that decision-makers’ social ties to external transaction partners can also hurt firm performance. Specifically, we use 34 years of data from the National Basketball Association and study the relationship between a team's winning percentage and its use of players that the manager acquired through social ties to former employers in the industry. We find that teams with “tie-hired-players” underperform teams without tie-hired-players by 5 percent. This effect is large enough to change the composition of teams that qualify for the playoffs. Importantly, we show that adverse selection of managers and teams into the use of tie-hiring procedures cannot fully explain this finding. Additional evidence suggests instead that managers deliberately trade-off private, tie-related benefits against team performance.
Using representative and geocoded data from the Swiss Household Panel and the Swiss Business Census, we estimate the effect of sports activity on health care utilization and health. Because sports activity is likely correlated with unobserved determinants of health care utilization and health, we use the number of sports facilities within 6 miles of the individual’s residence as an instrument. We find that doing sports at least once a week significantly reduces the number of doctor visits, overweight and sleeping problems. The magnitudes of these effects are larger in the IV estimations than in OLS estimations, which are biased toward zero due to reporting errors in sports activity and an omitted variable bias. To know the magnitudes of the causal effects is crucial for any kind of cost-benefit analysis of promoting individual sports activity.
We study the corruption control strategies at three Multinational companies (MNC) before, during, and after the disclosure of corruption scandals and the initiation of legal procedures. In particular, we want to explore why some MNCs after a corruption scandal exceed regulatory expectations, choose proactive strategies, and influence their environment as institutional entrepreneurs that define best practices and new industry standards. Other companies, by contrast, act in a more incremental and self-referred way. We build on the concept of legitimacy in institutional theory, distinguish four strategies to regain legitimacy: decoupling, isomorphic adaptation, moral reasoning, and substantial influence, and explain the choice and sequence of these strategies. While all three case firms managed to (eventually) adapt to the compliance requirements imposed by external regulatory authorities, we found that only very distinct constellations of scandal and reintegration process characteristics, such as the presence of a strong legitimacy shock and the necessity to react both radically and instantly, forces the company into the role of an institutional entrepreneur. In cases where such legitimacy shocks are lacking, companies have more time to react and hence rather choose to gradually adapt their organizational processes to regulatory expectations. Rather than acting as institutional entrepreneurs, these companies rely almost exclusively on participating in moral reasoning activities to safeguard their new anti-corruption strategy. However, if change processes occur rather reluctantly after the disclosure of a big scandal, we found that externally imposed monitors may exercise severe pressure forcing the transgressor to eventually install a leading set of corruption controls.
This study investigates the efficacy of public R&D support. Compared to most existing studies, we do not stop at substitution effects or general innovation outcome measures, but we are interested in knowing where the policy effect is highest: on innovation close to the market (i.e. incremental innovation) or on innovation that is still far from the market and hence more risky and radical. Using firm level data from the period 1999 to 2011, we find that the policy hits where the market failure is highest, that is, for radical innovation. Taking into account that the Swiss funding agency encourages collaboration, we find no evidence that the impact
of the policy is positively effected by various R&D collaboration patterns.
