The role of network embeddedness across multiple social networks: Evidence from mobile social network games

This article examines peer influences from network relationships within a social network game (i.e., embeddedness) and across such games (i.e., multiplexity). Drawing on social influence theory, we develop a bivariate Poisson model of users’ repeated visits and latent attrition that accommodates peer interaction after controlling for homophily. We estimate the model using data from two social network games with considerable overlap among network members. We find that friends who are only multiplex across games exert greater peer influence on users’ game visits than members who are embedded within a single game. We also determined that ignoring network multiplexity across games may lead firms to mistarget users due to biased peer influences of embedded friends. This result provides an unresearched explanation—strength of peer influence—for the mixed findings in previous literature on network embeddedness. We utilized our results to conduct several scenario analyses to demonstrate how firms can effectively manage users’ engagement and target users in multiple social network games.

Debtor-in-possession financing

Several recent papers have documented the benefits of debtor-in-possession (DIP) financing in the restructuring of firms in Chapter 11. However, the view on benefits is not unanimous and some legal scholars have raised doubts about DIP financing's effects on debt-holders and the possibility of expropriative wealth transfers. In this paper we address this issue by analyzing both stock and bond price data for a comprehensive sample of DIP loans and find significant positive abnormal stock and bond returns at the announcement of DIP loans. Also, we do not find evidence of wealth transfers from junior to senior debt-holders. Further, we examine the DIP loan process in detail and we document important institutional features of DIP loans such as maturity, covenants, fees and interest charges. We find evidence of intense monitoring using covenants. We also find higher fees and charges associated with DIP loans. We argue that overall the results are consistent with the information processing role of financial intermediaries.     

The effect of interfirm dependence structures on governance mechanisms

Despite recent developments regarding the study of interdependence structures, previous research has rarely investigated the simultaneous effect of both interdependence magnitude and interdependence asymmetry on governance mechanisms among exchange parties. A survey of manufacturing companies has been used to test a theory about the interactive effect of buyer dependence and supplier dependence on inter-firm governance. The analysis of the survey supported the proposition that both buyers and suppliers that are highly dependent on each other (high interdependence magnitude and low interdependence asymmetry) may choose to rely on monitoring and the norm of information sharing. However, when a buyer's dependence is low regardless of the supplier's dependence level, the buyer does not rely on the norm of information sharing (buyer's relative interdependence advantage, buyer's relative interdependence disadvantage, and low interdependence magnitude). On the other hand, when the supplier's dependence on the buyer is low, the buyer relies on monitoring regardless of its dependence level (buyer's relative interdependence disadvantage and low interdependence magnitude). However, this study did not empirically measure performance. Further research should be done on the effect of congruence between the governance mechanism and its antecedents on buying performance.     

Timing of environmental inspections: survival of the compliant

Environmental inspection agencies have limited resources. A natural response to this shortage of resources is targeting and this targeting policy leads to higher compliance than random inspections. This paper uses individual inspection data on the inspection policy of the environmental agency for the textile industry in Flanders (Belgium). We distinguish between three types of inspections and use a survival model to show that the environmental agency inspects firms in a non-random way. Even though the agency solves most environmental problems, it can increase compliance by using the deterrence effect of more stringent inspections and sanctions.

Environmental regulatory enforcement with “green” consumers

We consider a standard probabilistic model of random monitoring to analyze the interactions between a firm and a monitoring agency in the presence of “green” consumers when compliance payoffs are contingent on monitoring and monitoring costs are shared by the monitoring agency and the firm. When the amount paid by the firms if monitored is exogenously fixed, we find that full compliance is implemented with a finite fine. If there is an upper bound for the fine and the regulator determines endogenously the fine and the amount paid by the firms if monitored, we find that full compliance is also achieved, although the optimal fine is now set at its maximum level. The optimal amount paid by the firms if monitored is lower than the environmental premium the compliant firm gets.The author thanks two anonymous referees for their useful comments and suggestions     

Collaboration, peer review and open source software

Open source software development may be superior to proprietary development because the open source organizational form naturally minimizes transactions costs associated with privately distributed information. This manifests itself in the ability of open source communities to encourage critical peer review and the sharing of ideas. When these activities are important, the open source organizational form may do better than a proprietary organizational form. My results suggest why open source is particularly powerful when maintainability of software is critical, and also suggest that the founder of a software project may be more likely to choose open source if there is an existing dominant proprietary software project.

A prospective analysis of labour market status and self-rated health in the UK and Russia

Comparing prospective data from the UK and Russia, this paper analyzes whether the association of labour market status, and particularly unemployment, with subsequent health varies by the level of state protection provided to the unemployed. While the UK's unemployment welfare regime is classified as providing minimal protection, the Russian regime is sub-protective. Employing Cox duration analysis upon data from the Russian Longitudinal Monitoring Survey and the British Household Panel Survey for the period 2000–2007, this study finds that labour market status and economic circumstances independently predicted individual-level declines in self-rated health and, contrary to expectations, the associations of unemployment with health decline were similarly sized in the two countries.
