We analyze the impact of option trading and margin rules on the behavior of informed traders and on the microstructure of stock and option markets. In the absence of binding margin requirements, the introduction of an options market causes informed traders to exhibit a relative trading bias...

We test several hypotheses on how takeover premium is related to investors’ divergence of opinion on the target’s equity value. We show that the total takeover premium, the pre-announcement target stock price runup and the post-announcement stock price markup are all higher when investors...

This paper investigates the design of privatization mechanisms in emerging market economies. We identify an emerging market economy by the political constraints that limit the set of viable privatization mechanisms. Our objective is to explain the striking diversity of privatization mechanisms...

This paper shows that illiquid growth opportunities crucially impact the agency costs of risky debt. If the value of these growth opportunities is sufficiently high, they reverse riskshifting incentives into risk-avoidance incentives, creating a new agency cost of debt. They can also eliminate...
