Blockchains are the most well-known example of a distributed ledger technology (DLT). Unlike classic databases, the ledger is not maintained by any central authority. The integrity of the ledger is maintained automatically by an algorithmic consensus process whereby nodes vote and agree upon the...

We discuss the effect of pricing strategies by two firms on the total firm revenue, consumer and total welfare using simulation and numerical analysis. We consider pricing decisions for mixed bundling and where each firm offers two closely related products as well as a bundle. Bundling is a key...

Radio spectrum is a key input for mobile operators and the structure of the industry is strongly related to and influenced by the ownership of spectrum licenses. Spectrum is usually allocated for a limited duration and may or may not be tradable which further complicates the interaction between...

The COVID-19 pandemic has elicited a plethora of responses from health authorities. Even as vaccines have become more readily available, contact tracing has retained a central role (Fetzer & Graeber 2021; Ferguson et al. 2020; Pierucci & Walter 2020). Huge resources have been applied to expand...

Artificial intelligence (AI) techniques for natural language processing have made dramatic advances in the past few years (Lin 2023). Thunström & Steingrimsson (2022) demonstrated that the present generation of AI text engines are even able to write low-level scientific pieces about themselves,...

Artificial intelligence (AI) tools such as ChatGPT and GPT-3 have shot to prominence recently (Lin 2023), as dramatic advances have shown them to be capable of writing plausible output that is difficult to distinguish from human-authored content. Unsurprisingly, this has led to concerns about...

Bundling of broadband access with other services has been a defining characteristic of internet access markets for as long as broadband technologies have been available. Initially, cable television competitors entered telecommunications markets by bundling first voice telephony and subsequently...

The current mobile ecosystem is best understood in terms of a monopolistic competition model, characterised by heterogeneous producers providing a range of differentiated products for consumers with heterogeneous preferences. Product differentiation offers producers some market power, ultimately...
