We construct a model where the reputational concern of the long-run player to look good in the current period results in the loss of all surplus. This is in contrast to the bulk of the literature on reputations where such considerations mitigate myopic incentive problems. We also show that in models where all parties have long-run objectives, such losses can be avoided.

We use a simple model to outline the conditions under which corporate investment is sensitive to nonfundamental movements in stock prices. The key prediction is that stock prices have a stronger impact on the investment of “equity-dependent” firms—firms that need external equity to finance marginal investments. Using an index of equity dependence based on the work of Kaplan and Zingales, we find support for this hypothesis. In particular, firms that rank in the top quintile of the KZ index have investment that is almost three times as sensitive to stock prices as firms in the bottom quintile.
