Circular economy (CE) and sharing economy (SE) are much discussed concepts but potential links between them have not been examined systematically so far. The concepts’ popularity coupled with a lack of definitional consensus may hinder their potential to advance sustainability transitions. Hence, the first comparative bibliometric study of these two concepts was carried out. It was found that they share notable links in the fields of sustainability, business models, sustainable consumption and governance. Business model literature reveals links mostly in the realms of platform- and service-based activities. The field of SE has a strong consumer focus but, unlike CE, barely addressed rebound effects so far. Governance literature shows a general top-down dynamic driving CE, while SE is considered to be bottom-up. SE is conceptualized as a subset of CE which opens possibilities for mutual enrichment. The findings aim to provoke more dialogue between the CE and SE communities.@en

This paper relates the cost-benefit analysis (CBA) results of transportation policy proposals in the Netherlands with the decision to implement or abandon the proposal. The aim of this study is to explore the relation between the CBA results and decision-making. Multinomial logit regression models and Latent Class Analysis are used in this paper as the statistical tools to identify associations between CBA results and decisions and to reveal unobservable classes underlying the CBA results and the decisions for projects. Analysis was carried out on 106 Netherlands CBA reports (2000–2012) containing 454 observations. Each observation is a CBA result of a transport project variant. In line with most of the international literature, this study cannot find a significant association between Net Present Values (NPVs) and the variants chosen in political decisions (after controlling for other relevant variables). However, a positive NPV does keep variants ‘pending’, preventing a negative decision.@en

Faced with ever-increasing pressure to innovate, firms consider universities to be significant sources of knowledge. Such knowledge flow can take place in a variety of ways such as academic publications and contract research, but also in more collaborative modes such as joint research projects. This paper focuses on a specific collaborative model, in which firms and universities are involved together in a PhD project. We analyze the effects of project management, communication, and supervision characteristics on the success of such PhD projects using a survey conducted at Eindhoven University of Technology, the Netherlands. We conclude that management decisions, supervision and communication characteristics have a significant impact on the ultimate success of a project. Among other things, the choice of university supervisor plays a pivotal role. Success is more likely if there is joint decision-making by both university and partner. We believe our findings help universities and firms to collaborate successfully.@en
