This paper describes the different forces that shape the market structure of four different "online platform ecosystems" and the competition between them. The paper focuses on the following categories of platforms, which represent a wide scope of online activities: (i) e-commerce marketplaces;...

The aim of this paper is to explain evidence of unfair practices by online platforms towards business users, particularly SME's. First, using survey data, we show that sellers operating with four different categories of platforms multi-home (marketplaces, app stores, social networks and online...

This report presents evidence on the relationship between online platforms and businesses using these platforms to reach consumers or conduct their operations. First, we review the literature on vertical relationships both from a classic approach and from a multi-sided market perspective....

We present a novel generic theoretical framework to analyze the incentives agents have to engage in n-way data sharing or 'data pooling' and the factors affecting those incentives. Based on the results obtained, we provide policy recommendations aimed at fostering health data pooling. Section 1...

We investigate three alternative but complementary indicators of market power on one of the largest online labour markets (OLMs) in Europe: (1) the elasticity of labour demand, (2) the elasticity of labour supply, and (3) the concentration of market shares. We explore how these indicators relate...

Recent literature has shown that the existence of supply and demand-side non-generic complementarities ("demand-side linkages") within ecosystems raises questions about the pertinence of defining a single relevant market comprising substitute products ("substitutability approach"). However,...

This paper presents a legal and economic analysis of business-to-business (B2B) data markets. It starts from the economic characteristics of data and explores to what extent private B2B data markets result in a socially optimal degree of data sharing, or whether there are market failures in data...

Despite the rapidly growing volume and economic importance of data in the digital economy, the legal framework for data ownership, access and trade remains incompletely defined in the EU and elsewhere. De facto data ownership dominates and often leads to fragmentation or anti-commons problems in...

We analyse survey data to investigate the main barriers to European cross-border e-commerce. We investigate the determinants of selling online, as well as the frequency and determinants of cross-border e-commerce, and the role of barriers. Large firms, which are part of a group, are more likely...

Data and information are fundamental pieces for effective evidence-based policy making and provision of public services. In recent years, some private firms have been collecting large amounts of data, which, were they available to governments, could greatly improve their capacity to take better...
