Recently, “platform ecosystem” has received attention as a key business concept. Sustainable growth of platform ecosystems is enabled by platform users supplying and/or demanding content from each other: e.g. Facebook, YouTube or Twitter. The importance and value of user data in platform ecosystems is accentuated since platform owners use and sell the data for their business. Serious concern is...

The mobile telecommunications industry is undergoing a rapid change, which is increasing the interdependency of firms in the sector. This trend increases the likelihood that mobile information and entertainment services will be delivered through inter-organisational networks of firms. These networks are the topic of this research. In particular we examine service networks and the possible influ...

States producing gas and oil have long levied severance taxes at the point of extraction, commonly placing most revenues into general funds. These taxes have assumed new meaning in many states amid the expansion of gas and oil production accompanying the advent of hydraulic fracturing. We reviewed all major statutes and constitutional amendments related to severance taxes that were enacted at t...

Along with substantial progress made recently in designing near-optimal mechanisms for multiitem auctions, interesting structural questions have also been raised and studied. In particular, is it true that the seller can always extract more revenue from a market where the buyers value the items higher than another market? In this paper we obtain such a revenue monotonicity result in a general s...

In combinatorial auctions using VCG, a seller can sometimes increase revenue by dropping bidders. In this paper we investigate the extent to which this counter-intuitive phenomenon can also occur under other deterministic dominant-strategy combinatorial auction mechanisms. Our main result is that such failures of “revenue monotonicity” can occur under any such mechanism that is weakly maximal—m...

The paper examines government IT outsourcing polices. The paper critiques the concept of ‘the Contract State’, and suggests how more disciplined uses of outsourcing can assist the creation of public value, more broadly conceived. Within the context of international developments, we study the United Kingdom Inland Revenue (IR), Customs and Excise (HMRC) and Department of Social Security (DSS) an...

Daily-deal business model is a type of performance-based advertising wherein a publisher provides advertising space to a merchant who pays a proportion of revenue generated on the website to the publisher. We develop a two-period model to capture the strategic interaction between a publisher and a merchant where consumers are heterogeneous in their willingness to pay for quality and awareness a...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...

In this paper, we analyze cost sharing problems arising from a general service by explicitly taking into account the generated revenues. To this cost-revenue sharing problem, we associate a cooperative game with transferable utility, called cost-revenue game. By considering cooperation among the agents using the general service, the value of a coalition is defined as the maximum net profit that...
