We find a U-shaped relation between industry concentration and innovation. The relation is driven by neck-and-neck industries where firms operate with similar productivity. When industry concentration is low, innovation intensity decreases as concentration increases. However, when industry...

We examine how retailers discount the prices of product systems versus their constituent components. The topic is important because such systems are ubiquitous in our daily lives. In particular, many high-tech markets revolve around complex multi-component systems – e.g. a camera system...

The problem of managerial agency costs dominates debates in corporate law. Many leading scholars advocate reforms that would reduce agency costs by forcing firms to allocate more control to shareholders. Such proposals disregard the costs that shareholders avoid by delegating control to managers...

Scholars and antitrust enforcers have raised concerns about anticompetitive effects that may arise when institutional investors hold substantial stakes in competing firms. Their concern rests on empirical evidence that such common concentrated ownership is associated with higher prices and lower...

Partial ownership of stock in multiple competing firms is an important scholarly and policy topic in both corporate and antitrust law. Until now, the discussion has focused on ownership. This essay shifts the debate from a focus on common ownership to a focus on common control. No prior work has...

Minority shareholdings have been on the regulatory agenda of competition authorities for some time. Recent empirical studies, however, draw attention to a new, thought provoking theory of harm: common ownership by institutional investors holding small, parallel equity positions in several...

A phenomenon known as “Common Ownership” arises when shareholders hold substantial stakes in competing firms. Although recent empirical evidence has illustrated how common concentrated owners are associated with higher product market prices and lower output, scholars remain divided as to the...

The paper argues that the major existing economic theories of nonprofit organisation are most suitable to those nonprofits which are protecting and promoting private rather than public interests. These theories therefore do not offer an adequate explanation why some nonprofits do directly serve...

Horizontal shareholding exists when significant shareholders have stock in horizontal competitors. (It is often imprecisely called "common shareholding," but that term can also apply when shareholders own stock in two noncompeting corporations. It differs from "cross-shareholding," which...

This Article shows that new economic proofs and empirical evidence provide powerful confirmation that, even when horizontal shareholders individually have minority stakes, horizontal shareholding in concentrated markets often has anticompetitive effects. The new economic proofs show that,...
