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...

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...

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...

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 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...

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...

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...

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, fully-structural model. Our model embeds a state-of-the-art hedonic demand system, endogenizes firms' markups 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)...

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...

The Digital Services Act (DSA) marks a paradigmatic shift in platform governance, introducing mechanisms like the Statement of Reasons (SoRs) database to foster transparency and observability of platforms' content moderation practices. This study investigates the DSA Transparency Database as a...

We investigate how new land releases affect the pricing of nearby parcels in a standardised virtual real estate market. Using 9920 secondary-market transactions from The Sandbox on the Ethereum blockchain, we implement a difference-in-differences design around expansion announcements. Nearby...

The article presents the uptake and development of instant payments across countries representing various geographies with diverse economic and social backgrounds. It identifies the critical success factors for the rapid adoption of instant payments.This study features five country cases where...

In many industries, platforms compete with incumbents that are open to all consumers, whereas platforms require user affiliation. Consequently, platforms face two layers of competition: for the market, to attract users, and in the market, to compete with incumbents. We develop a dynamic model...

The decision delivered by the European Court of Justice in Android Auto may represent a watershed moment in competition policy for digital markets. By requiring dominant platforms to accommodate third-party requests to enable interoperability, the judgment could significantly affect their design...

We incorporate the endogenous feedback loop at the core of the seminal Schelling (1969) model of segregation into a dynamic model of neighborhood choice and use it to study the forces that shaped racial and income segregation in the San Francisco Bay area from 1990 to 2004. Such an analysis...
