Can managers influence the liquidity of their shares? We use plausibly exogenous variation in the supply of public information to show that firms seek to actively shape their information environments by voluntarily disclosing more information than is mandated by market regulations and that such efforts have a sizeable and beneficial effect on liquidity. Firms respond to an exogenous loss of public information by providing more timely and informative earnings guidance. Responses are greatest when firms lose local information producers and appear motivated by a desire to communicate with retail investors. Liquidity improves as a result of voluntary disclosure.Key words: Liquidity; Voluntary disclosure; Earnings guidance; Information production; Management communication; Investor relations; Analyst coverage; Retail investors.
JEL classification: G12, G24, M41.Improved liquidity raises a firm's market value by lowering its discount rate (see Amihud and Mendelson (1986, 1989), Brennan and Subrahmanyam (1996), and Amihud (2002)). While liquidity is often viewed as resulting from market makers' and investors' actions in an exogenously specified information environment, we examine if corporate managers can actively influence the liquidity of their shares. An important channel through which they might do so is voluntary disclosure. Theoretical models such as Diamond (1985) and Diamond and Verrecchia (1991) show that managers may voluntarily disclose more information than is mandated by market regulations in order to reduce information asymmetry among their investors. Consistent with this, recent survey evidence suggests that managers provide voluntary disclosure to "reduce the information risk that investors assign to our stock" (Graham, Harvey, and Rajgopal (2005)).Whether managers can indeed affect their information environments, and thereby their liquidity and cost of capital, remains an open question. The main challenge is that voluntary disclosure is voluntary: Managers choose to disclose more information for reasons that could well affect their firm's liquidity directly. For example, empirical studies suggest that firms tend to disclose more when their earnings are easier to predict (Chen, Matsumoto, and Rajgopal (2011)); but lower earnings uncertainty would reduce information asymmetry, and so increase liquidity, independently of disclosure. Thus, showing that disclosure affects liquidity causally, and by how much, has proved challenging. This endogeneity problem leads Leuz and Schrand (2009) to conclude that "the empirical evidence … is far from conclusive."We use plausibly exogenous variation in the supply of public information to show that firms seek to actively shape their information environments through voluntary disclosure and that such efforts improve their liquidity. The former result confirms the central assumption made in theoretical models of disclosure. The latter result contributes to our understanding of liquidity in financial markets, by showing that managers can actively influen...
