    Abstract: Supply of fresh food is of vital importance to feed Europe in a healthy way, while Europe has also an important role in feeding the world. Food products and other perishables such as flowers impose very challenging demands on the management of its supply chains. Food networks are struggling with an integrated usage of information and communication technology (ICT) that enables the heterogeneous stakeholders in the food chain to exchange information in real-time and control workflows based on requirements with respect to quality, costs and schedule. Innovative ICT systems that are addressing such challenges are currently being developed by a large European initiative, called FIWARE. Within this paper, we will discuss a portfolio of 31 projects that are realising solutions for the food chain in close collaboration with supporting business partners. Diverse food related topics are addressed, such as logistics, transport, planning & control, tracking & tracing, information management as well as new ways to realise e-commerce within the chain as well as for consumers. The FIWARE initiative is accelerating startups and supporting SME type technology developers that are realising solutions for real world business cases, which are serving as reference customers and test cases to assure an end-user acceptance and valid business models. This paper discusses the main food chain related topics and innovation potentials that are addressed as well as outlining the related methodological and technological approaches that are used to facilitate the realisation of impact and growth for commercial exploitation.

    Abstract: Local interactions and network structures appear to be a prominent feature of many environmental problems. This paper discusses a wide range of issues and potential areas of application, including the role of relational networks in the pattern of adoption of green technologies, common pool resource problems characterized by a multiplicity of sources, the role of social networks in multi-level environmental governance, infrastructural networks in the access to and use of natural resources such as oil and natural gas, the use of networks to describe the internal structure of inter-country relations in international agreements, and the formation of bilateral “links” in the process of building up an environmental coalition. For each of these areas, we examine why and how network economics would be an effective conceptual and analytical tool, and discuss the main insights that we can foresee.
    Keywords: networks; environmental externalities; technological diffusion; gas pipelines; common-pool-resources; multi-level governance; coalitions

    Abstract: Reputation is critical to foster trust in online marketplaces, yet leaving feedback is a public good that can be under-provided unless buyers are rewarded for it. Signaling theory implies that only high quality sellers would reward buyers for truthful feedback. We explore this scope for signaling using Taobao's "reward-for-feedback" mechanism and find that items with rewards generate sales that are nearly 30% higher and are sold by higher quality sellers. The market design implication is that marketplaces can benefit from allowing sellers to use rewards to build reputations and signal their high quality in the process.

    Abstract: Online marketplaces have proliferated over the past decade, creating new markets where none existed. By reducing transaction costs, online marketplaces facilitate transactions that otherwise would not have occurred and enable easier entry of small sellers. One central challenge faced by designers of online marketplaces is how to build enough trust to facilitate transactions between strangers. This paper provides an economist’s toolkit for designing online marketplaces, focusing on trust and reputation mechanisms.
