Der vorliegende Abschlussbericht entstand im Rahmen des Forschungsprojektes "Plattformökonomie und soziale Sicherung: Arbeits- und Sicherungsorientierungen digitaler Selbstständiger zwischen De- und Re-Institutionalisierung". Das Kooperationsprojekt zwischen dem Institut Arbeit und...

This document is part of a series presenting information and lessons learned on policy approaches at national, regional or local level supporting a just transition to a climate-neutral economy. The Just Transition Platform (JTP) assists EU Member States and regions to unlock the support in this...

As digital platforms continue to evolve, they facilitate the exchange of information and create opportunities for innovation-driven growth and introduce new challenges for enterprises navigating research and development-driven transformation. In the study, we used the Probit model, IV-Probit...

We collect observations on how power constitutes itself in decentralized digital platform constellations that position themselves as alternatives to platforms operated by big tech (which we coin "hyperledgers"). We then compare these forms of power to the incumbent structures, the so called...

In this special issue, we refer to "content moderation" as the multi-dimensional process through which content produced by users is monitored, filtered, ordered, enhanced, monetised or deleted on social media platforms. This process encompasses a great diversity of actors who develop specific...

This paper introduces modern readers to ‘banking theory’, that is, to the understanding of the banking system that was held by academics and practitioners in the early years of the twentieth century. This theory contrasts with the theoretic framework that views banks as intermediaries that...

Online platforms have evolved into powerful programmable architectures that enable heterogeneous groups of autonomous but interdependent users to interact. Based on a stratified sample of 1,380 companies from a newly developed enterprise survey in Austria, the analysis aims to reduce the lack of...

We consider a market in which a platform hosts third-party monopolistic complementors. Users are segmented into single-use and multi-use consumers, and services exhibit network externalities. In the agency model, the presence of multi-use consumers leads complementors to set inefficiently high...

This paper introduces a novel mechanism by emphasizing benefits for firms through participation in buyer networks among firms that source the same locally produced inputs. In a first step, we utilize register-based data from Denmark to generate a firm-specific buyer network variable which relies...

We study the welfare effects of a merger between ad-funded platforms facing elastic consumer demand. We show that advertising fees as well as quality investment levels by the platforms fall post-merger. Interestingly, despite the lower advertising fees, advertisers may be worse off when their...

Market definition is essential for antitrust analysis, but challenging in settings with network effects, where substitution patterns depend on changes in network size. To address this challenge, we conduct an incentivized experiment to measure substitution patterns for TikTok, a popular social...

A paradox arises in platform-based open innovation, wherein digital Multi-Sided Platform (MSP) firms with little initial co-creation ability can successfully adopt an open innovation strategy that typically requires a high level of co-creation capacity. This study aims to fill this gap by...

This study investigates a novel challenge within the digital economy: scrounging, which entails the exploitation of false identities to capitalize on benefits offered by digital platforms, such as sales promotions and new user incentives. As a form of fraud, scrounging can substantially affect...

The process of the liberalisation of services of general economic interest (SGEI) in the EU adopted the universal service (US) regulatory model. The objectives of the process were to strengthen free competition and improve social welfare. SGEIs have the characteristic of networked services and,...

In this paper, we advance the network theory of aging and mortality by developing a causal mathematical model for the mortality rate. First, we show that in large networks, where health deficits accumulate at nodes representing health indicators, the modeling of network evolution with Poisson...
