We model the impact of public and private ownership structures on firms' incentives to invest in innovative projects. We show that it is optimal to go public when exploiting existing ideas and optimal to go private when exploring new ideas. This result derives from the fact that private firms...

We provide new evidence on the role of real money balances in terms of explaining equity risk premia by using a rich cross-section of average stock returns (associated with 11 major CAPM anomalies). By estimating Euler equations associated with a cash-in-advance (CIA) model, we find that such...
