This article reviews the regulatory campaign against China’s online platform sector that took place between 2020 and 2022. It focuses specifically on its substantive policy aspects, arguing that this “rectification” both intended to remedy existing perceived problems in the online platform...

Modern software development involves collaborative efforts and re-use of existing software packages and libraries, to reduce the cost of developing new software. However, package dependencies expose developers to the risk of contagion from bugs or other vulnerabilities. We study the formation of...

There is a harmful mismatch between how information published by the government is perceived—as highly trustworthy—and the reality that it is often not. This Article shows that the government frequently collects information from third-party private entities and publishes it with no review or...

We propose a two-sided market entry game and present experiments studying coordination behavior in the game. The two-sided market in the game is operated by an intermediary monopoly platform, serving two sides (i.e., customers and service providers) and featuring asymmetric agents, cross-side...

Banks carry significant exposures to nonbanks from direct dealings, but they can also be exposed, indirectly, through losses in asset values resulting from fire-sale events. We assess the vulnerability of U.S. banks to fire sales potentially originating from any of twelve separate nonbank...

In this paper we empirically address the issue of whether reductions in card payment interchange fees have a significant impact on prices paid by consumers. The answer to this question is at the core of most competition policy cases and regulations that have been applied to card payment markets....

Purpose: This paper addresses a gap in research literature in the fields of blockchain technology (BC), supply chain network dynamics (SC) and network effect phenomena (NE). Extant BC and SC literature describes the potential benefits to be reaped through the adoption of BC technology. While BC...

We decompose the macroeconomic impact of Covid-19 in the US using three production network measures. First, we estimate the aggregate indirect effect of sectoral employment shocks, finding these “network spillovers” to account for ≈72% of the decline in real GDP over the second quarter of...

Platform economies are depicted as the foundation for a new era of economic production. This transpires through the incorporation of digital technologies and algorithmic operations into the heart of economic and financial practices. However, different assumptions are made about the effects of...

Flexibility is recognized as one of the major shifts in the future of work. As emerging forms and structures of work challenge us to rethink how work is organized, specifically through the digitization of work by digital platforms, we are witnessing shifts in workplaces that challenge common...

Modern ICT services are characterized by pervasive connectivity and the need for applications that are always on (24/7); a new way of designing and operating such services is therefore essential. To cope with these requirements, a proper system architecture design and an effective and efficient...

This study examines the impact of technology and network externalities on exchange-listed Initial Coin Offerings (ICOs). Utilising an online database comprising of self-reported ICO characteristics, measures of post-ICO performance, along with information on business social networks, higher...

I analyze how the food delivery market’s indirect network effect and spillover effect influence the spread of food delivery platforms in different counties. This study finds that there is a positive local indirect network effect and a positive spillover effect in the adoption of the platform...

The regulation of digital platforms is frequently framed as a legal and institutional trade-off. Should policy makers “regulate” or should they “break-up” Big Tech? Should they decentralize digital power or should they transform companies like Google into accountable bottlenecks? These...

Digital platforms have become an important part of the digital economy by facilitating transactions between large numbers of users and by fostering innovation on collaborative platforms. In combination with technical platform services, some platform operators have managed to create powerful...

Platform interoperability is considered a powerful tool to promote competition in digital markets when network effects are at play. We study the effect of interoperability on competition between two ad-financed platforms, allowing for endogenous multi-homing of consumers. When the platforms are...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

We study an e-commerce platform’s incentive to enter the credit market and offer loans for vendors’ innovations. The platform earns from both its lending ac- tivity and fees collected on transactions in the marketplace. If the platform does not offer loans, it might find it convenient to...

Information constraints rank high among barriers to agricultural technology adoption among small-scale farmers, particularly for complex bundles of complementary practices that may involve several components for successful implementation. Information communication technologies (ICTs) are...

We develop a model that classifies platforms in the "creator economy"---e.g. Youtube, Patreon, and Twitch---into three broad business models: pure discovery mode (providing recommendations to help consumers search for creators); pure membership mode (enabling individual creators to monetize...

The connections and volatilities of financial institutions are important features in studies on the financial market. Based on the tail-event-driven networks reflecting the risk interdependence between financial institutions, we introduce quantile regression to achieve the dynamic ranking of...
