Abstract: This Feature presents a critical evaluation of the existing literature regarding pro-competitive regulation of digital platforms and contributes to the literature by bringing out the implications for India and South Korea. These countries provide a unique example of the presence of large domestic digital platforms alongside large multinational ones. The implications of regulation of digital platforms for jurisdictions like India and South Korea require a nuanced understanding of the trade-offs involved in such regulations. This Feature works out two important trade-offs for regulators in India and South Korea which can guide the decision-making process around digital market regulations and offers a unique core market approach for regulators to avoid the pitfalls of a threshold-based identification of dominant large digital platforms.
