From the article: "To extend the lifetime of products, an agent is connected to the product. This agent has several roles. It depends on the phase of the lifecycle what these roles will be. One of the roles in the usage or recycling phase is to negotiate for buying spare parts in case a part of the product is broken. The same agent can also decide to offer spare parts to other agents to reuse working parts of a broken product. To accomplish this idea, a marketplace for agents has to be set up, where the auctions can take place. To support this concept, blockchain technology has been used. Blockchains are a new type of technology, known from bitcoins, but there are other cases where blockchains can be used. Blockchain is known for its decentralisation, transparency and for making trustful transactions. In this paper the working of different types of blockchains will be briefly explained and determined if they can be useful for online auctions by agents. A prototype of the marketplace using blockchains has been built."

Consumer concern for animal welfare is currently not fully reflected in the market share of welfare-enhanced meat. A possible solution is developing marketing strategies that emphasize personally relevant benefits such as taste and curiosity, instead of having a sole focus on sustainability-related benefits, since existing research indicates that the former are more appealing to most consumers. This study tests strategies positioning welfare-enhanced meat as personally relevant in a real-life experiment and how consumer attitudes towards eating meat influence reactions to the positioning strategies. The study conducts experimental auctions with 101 Dutch university students, manipulating the positioning strategy and a certified animal welfare label and measuring participants’ willingness to pay (WTP) for a lunch meal with chicken meat. Results indicate that all manipulations significantly increase consumer WTP, with higher WTP for certified labels than for the positioning strategy, and the highest WTP for the combination of both elements (without providing evidence for an interaction effect). This implies that companies should combine positioning strategies that emphasize personally relevant benefits with certified labels. Since the effectiveness of such strategies may be limited for consumers with conflicting feelings towards meat, some care should be taken when designing awareness campaigns about the effects of meat consumption

Concerns about the negative consequences of the excessive underpricing of the current arrangement in the initial public offering (IPO) market for the provision of entrepreneurial finance—book building—have led to research into the viability of auctions for IPO pricing and allocation. IPO firms face a trade-off between the benefit of accurate and reliable IPO price discovery and the cost of underpricing. The main aim of this paper was to gain new scientific knowledge about this trade-off by measuring the impact of two key variables on this trade-off: capacity restraint and discount on the auction clearing price. Using controlled experiment methodology in multi-unit uniform price auctions we found that the most capacity-restricted auctions that also offer investors a discount are likely to produce the most accurate and reliable price discovery and consequently, the most predictable auction outcome. There are indications that a discount of 8% may suffice to incentivize investors to reliably contribute to price discovery. The resulting underpricing (and its variability) of these auctions is likely to be significantly lower than if book building would be used to price and allocate IPOs. Technological innovation in the IPO market through the application of recent advances in data science, experimental economics and artificial intelligence allows for the optimization of IPO mechanisms and crowdfunding platforms which in turn improves the access to equity required for entrepreneurial finance.

This study proposes a systematic value chain approach to helping businesses identify and eliminate inefficiencies. The authors have developed a robust framework, which food-sector entrepreneurs can use to increase profitability of an existing business or to create new profitable opportunities. The value chain approach provides win-win opportunities for players within the value chain. To test the robustness of the framework, the authors use food waste as an example of a critical inefficiency and apply it to two different food sector business cases, each operating in diverse conditions. Because the suggested framework addresses the core elements and parameters for the existence and competitiveness of a business, the model can be adapted to other sectors.

The benefits of collaborative purchasing are many, yet in the healthcare sector, in particular at hospitals, it is still uncommon. In this paper we identify major impediments for collaborative purchasing, resulting in a first component of our proposed collaborative e-purchasing model for hospitals; as a second component it contains a collaborative purchasing typology. After analysis of a first validation round with hospital purchasing professionals, the results show four applicable purchasing types and fourteen collaborative purchasing impediments that are perceived as important for hospitals. The model is further extended by possible IT solutions, identified by experts, addressing the specific fourteen impediments. We conclude that the collaborative e-purchasing model can be used by healthcare consortia, branche organizations, partnering healthcare institutes and multi-site healthcare institutes as a means to help identifying strategies to initiate, manage and evaluate collaborative purchasing practices.

Peer-to-peer (P2P) energy trading has been recognized as an important technology to increase the local self-consumption of photovoltaics in the local energy system. Different auction mechanisms and bidding strategies haven been investigated in previous studies. However, there has been no comparatively analysis on how different market structures influence the local energy system’s overall performance. This paper presents and compares two market structures, namely a centralized market and a decentralized market. Two pricing mechanisms in the centralized market and two bidding strategies in the decentralized market are developed. The results show that the centralized market leads to higher overall system self-consumption and profits. In the decentralized market, some electricity is directly sold to the grid due to unmatchable bids and asks. Bidding strategies based on the learning algorithm can achieve better performance compared to the random method.

Horizontal collaborative purchasing (HCP) has often been cited as a way for hospitals to address the challenges of the rising healthcare costs. However, hospitals do not seem to utilize horizontal collaborative purchasing on any large scale, and recent initiatives have had mixed results. Focusing on Dutch hospitals, in this paper we present major impediments for collaborative purchasing, resulting in a first component of our proposed electronic horizontal collaborative purchasing model for hospitals; as a second component it contains a collaborative purchasing typology. A first validation round with hospital purchasing professionals, described separately in Kusters and Versendaal (2011), confirmed four applicable purchasing types and fourteen salient collaborative purchasing impediments. The model is operationalized by including possible information technology (IT) solutions that address the specific fourteen impediments. This model is validated through methodological triangulation of four different validation techniques. We conclude that IT has the potential to support, or overcome, the impediments of HCP. The validation also reveals the need to distinguish between more processrelated, as opposed to social-related, obstacles; the immediate potential for IT solutions is greater for the process-related impediments. Ultimately, we conclude that the collaborative epurchasing model (e-HCP) and implementation roadmap can be used by healthcare consortia, branche organizations, partnering healthcare institutes and multi-site healthcare institutes as a means to help identifying strategies to initiate, manage and evaluate collaborative purchasing practices

The Dutch greenhouse horticultural industry is characterized by world leadership in high-tech innovation. The dynamics of this playing field are innovation in production systems and automation, reduction in energy consumption and sharing limited space. However, international competitive advantage of the industry is under pressure and sustainable growth of individual enterprises is no longer a certainty. The sector's ambition is to innovate better and grow faster than the competition in the rest of the world. Realizing this ambition requires strengthening the knowledge base, stimulating entrepreneurship, innovation (not just technological, but especially business process innovation). It also requires educating and professionalizing people. However, knowledge transfer in this industry is often fragmented and innovation through collaboration takes up a mere 25-30% of the opportunities. The greenhouse horticulture sector is generally characterized by small scale, often family run businesses. Growers often depend on the Dutch auction system for their revenues and suppliers operate mainly independently. Horizontal and vertical collaboration throughout the value chain is limited. This paper focuses on the question: how can the grower and the supplier in the greenhouse horticulture chain gain competitive advantage through radical product and process innovation. The challenge lies in time- to-market, in customer relationship, in developing new product/market combinations and in innovative entrepreneurship. In this paper an innovation and entrepreneurial educational and research programme is introduced. The programme aims at strengthening multidisciplinary collaboration between enterprise, education and research. Using best practice examples, the paper illustrates how companies can realize growth and improve innovative capabilities of the organization as well as the individual by linking economic and social sustainability. The paper continues to show how participants of the programme develop competencies by means of going through a learning cycle of single-loop, double-loop and triple loop learning: reduction of mistakes, change towards new concepts and improvement of the ability to learn. Furthermore, the paper discusses our four-year programme, whose objectives are trying to eliminate interventions that stimulate the innovative capabilities of SME's in this sector and develop instruments that are beneficial to organizations and individual entrepreneurs and help them make the step from vision to action, and from incremental to radical innovation. Finally, the paper illustrates the importance of combining enterprise, education and research in networks with a regional, national and international scope, with examples from the greenhouse horticulture sector. These networks generate economic regional and national growth and international competitiveness by acting as business accelerators.
