This paper reviews the theoretical and empirical foundations of peer and network effects, aiming to bridge insights from both literatures. We first analyze the microfoundations of peer effects through linear-quadratic network games, linking equilibrium behavior to network centrality and...

Digitalization is increasingly central to economic growth strategies, yet robust macro-level evidence on the role of SME-led e-commerce remains limited. Drawing on the Resource-Based View, this study examines how SME digitalization, internet finance, and platform-based activities influence...

The US dollar (USD) has long been the dominant international currency. The euro (EUR), UK pound (GBP), Japanese yen (JPY), and other advanced economy (AE) currencies have played complementary roles to the USD as international currencies, while emerging market and developing economy (EMDE)...

ndustrial policy has returned to the centre of economic governance, particularly in the high-tech sectors where positive network externalities in demand make market dominance self-reinforcing. This paper studies the welfare effects of an industrial policy targeting a sector with network...

We present a new dynamic model of corporate investment in imperfectly-competitive product markets, extending the neoclassical (Q) theory of capital to a multi-firm, multi-product, fullystructural model. Our model embeds a state-of-the-art hedonic demand system, endogenizes firms' markups and...

Despite extensive research on migrants and the platform economy, few systematic comparisons exist between migrant and non-migrant workers across diverse migrant groups and types of platform work. This article draws on representative survey data from 14 European Union Member States, which shows...

This study examines how organizational models are evolving beyond post-Fordism in the context of digitalization, platformization, and new forms of labor governance. Using a bibliometric analysis of 1573 Web of Science publications, the article maps the intellectual genealogy, disciplinary...

We study competition between a welfare-maximizing public platform and a profit-maximizing private platform in a two-sided payment market. We characterize the public platform's optimal pricing and show that it balances the benefits of increased competition against the welfare costs of network...

This paper explores how the evolving platform economy is reshaping the economic landscape across Asia and the Pacific, and how countries in this diverse region are navigating emerging opportunities and challenges. It situates platform work within the broader context of the region's economic...

Online ratings emerge from a multi-stage process that can systematically distort their informational content. We develop a unified framework decomposing the rating process into distinct components: experienced quality (driven by intrinsic quality, seller effort, and price), expectations formed...

Platforms that provide product recommendations to consumers, such as marketplaces like Amazon or online travel agencies like Expedia, govern a substantial part of transactions in many markets. In addition to selling via platforms, most firms, however, also operate a direct channel. This paper...

The rapid development of network technology and live-streaming sales has facilitated the emergence of artificial intelligence digital human (AI) live-streaming technology, posing new challenges to traditional key opinion leader (KOL) live-streaming, particularly in highly competitive market...

The digital divide between large enterprises and SMEs (Small and Medium-sized Enterprises) within industrial clusters poses a significant challenge to achieving collective digital transformation, exacerbated by the quasi-public goods, attributes of digital inclusion ecosystems, and the...

In December 2025, Australia became the first country to ban youth under 16 years old from holding accounts on major social media platforms, a policy now under consideration in more than a dozen countries and in numerous states. Because social media use is inherently social, the effectiveness of...

Online platforms connecting physicians and patients are increasingly common and often operate in heavily regulated contexts. We consider a platform that provides cost-reducing services for physicians and quality-enhancing services for patients. The platform also improves the matching between...

This article critically analyses the enforcement framework of the EU Digital Markets Act (DMA), with a focus on its early operational phase. The DMA establishes a new regulatory regime that addresses entrenched platform power through ex ante obligations on designated gatekeepers. Building on the...

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...

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...

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...

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 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...

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...

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...

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...
