Ownership, Governance and Investment
Abstract
The US business sector has under-invested relative to Tobin's Q since the early 2000s; and the under-investment appears to be explained by decreasing competition (due to both increasing concentration and common ownership) and tight or short-termist governance [Gutiérrez and Philippon, 2016]. In this paper, we use a combination of natural experiments and instrumental variables to establish a causal relationship between increased quasi-indexer institutional ownership and decreased investment. In particular, we use the Russell index threshold as a natural experiment, and lagged quasi-indexer ownership as an IV. We find that higher quasi-indexer ownership leads to higher buybacks and less investment. We then study the interaction between governance and competition in causing under-investment and find contrasting results. At the firm-level, governance matters most for firms in non-competitive industries: they tend to buyback more shares and invest less. At the industry-level, anti-competitive effects of common ownership disproportionately affect industries that 'appear' competitive according to traditionalmeasures but actually are not (due to common ownership).
