Market power on each side of a multisided platform, whether in the form of increasing prices or decreasing quality, is constrained by the risk of losing sales on the other sides. That tends to weaken market power on each side and encourages platforms to keep prices lower and quality higher than...

In the economic literature on market competition, firms are often modelled as individual decision makers and the internal organization of the firm is neglected (unitary player assumption). However, as the literature on strategic delegation suggests, one can not generally expect that the behavior...

We provide a new rationale for bi-sourcing, which refers to the situation where a final goods producer buys an input from an outside supplier and also produces it in-house. We also show the effects of the product market competition and the implications of different and common outside input...

Many online businesses, including most of the largest platforms, seek and provide attention. These online attention rivals provide products and features to obtain the attention of consumers and sell some of that attention, through other products and services, to merchants, developers and others...

After decades of theoretical inquiry, a burgeoning empirical literature now debates how ownership patterns, governance choices, and executive compensation structure affect firms' competitive behavior. An often-made assumption in the debate is that relative performance evaluation (RPE) of top...

This paper examines the interaction between venture risk, product market competition and entrepreneurs' choice between bank financing and venture capital (VC) financing. Under bank financing, a debt-type contract emerges as optimal, which allows the entrepreneur to retain full control of the...

From the angle of competition policy, Voice over IP looks like a panacea. It not only brings better service, but it also increases competitive pressure on former telecommunications monopolists. This paper points to the largely overlooked downside. In a pure world of Internet telephony, there...

The theoretical relationship between market structure (number of firms) and conduct (pricing behavior) of the generic drug industry was investigated. The effects of qualitative variables such as therapeutic category, duration of use, popularity, and market entry aggressiveness on the...

In this paper, we study how the presence of a news aggregator affects competition among (horizontally differentiated) newspapers in the Internet. For this purpose, we build a model of multiple issues which allows each newspaper to choose quality on each issue. Our model provides a micro...

Recent claims that online platforms have secured permanent monopolies, protected by barriers to entry from network effects and stockpiles of data, and should be the focus of intense antitrust and regulatory scrutiny, are inconsistent with the economics, technology, and history of online...
