We study how investability, or openness to foreign equity investors, affects firm value in a sample of over 1,400 firms from 26 emerging markets. We find that, on average, investability is associated with a 9% valuation premium (as measured by Tobin’s q). This significant valuation premium persists in firm-fixed effects regressions, although the magnitude and robustness of the premium is somewhat lower. Analysis of the components of Tobin’s q shows that firms that become investable experience significant increases in both market values and physical investment. These effects are strongest for firms that face country-level or firmlevel financial constraints prior to becoming investable.
