“  I am working on various issues in corporate finance: capital structure; investment efficiency; innovation; payouts and cash holdings; and corporate social responsibility. In particular, I am interested in strategic interactions between firms and the interaction between stock markets and corporate decisions. I am also interested in evaluating various policy issues (e.g. business taxation and fiscal policies).  ”
