Exploring the economic impact of regulation in digital markets

The specialized information industry, represented by the Software & Information Industry Association (SIIA), commissioned Oxford Economics to undertake a research program to explore the economic implications of policy interventions in the realm of digital markets.

Digital technologies have risen to prominence as a critical determinant of economic growth, national security, and international competitiveness and this has contributed to an increase in scrutiny for companies in this sector. From an antitrust perspective, this has been amplified by the size that selected digital platforms have achieved.

In this context, this report aims to provide an assessment of the economic impact of existing digital markets regulation in Europe and the United States, drawing upon existing literature, insights from industry leaders, and data analysis to produce a balanced review of the implications of competition policy.

A key theme that emerged from the theoretical review is the existence of trade-offs in digital markets regulation, particularly in relation to how legislation intended to promote small and potential new market entrants might stifle platforms’ incentives and ability to fund frontier innovation.

The objective of this program is to educate readers and interested parties to build awareness and a deeper understanding of the intended and unintended effects of antitrust legislation focusing on digital markets.

Listen to The Business of Information podcast (Episode 9) featuring Alice Gambarin, exploring the economic impact of digital markets regulation.
