Optimal internal control regulation: Standards,penalties, and leniency in enforcement

To protect investors, regulators increasingly rely on regulating firms’ internal controls over financial reporting, but they punish noncompliance only if an internal control weakness enabled accounting manipulation. In other words, enforcement is manipulation-contingent. We develop an economic model with a manager who sequentially chooses internal control quality and manipulative effort, and a welfare-maximizing regulator who determines an internal control standard, the penalty size for internal control weaknesses, and when to invoke such a penalty. Internal control regulation under manipulation-contingent enforcement not only provides incentives to invest in internal controls, but also improves manipulation deterrence when there are internal control weaknesses. The optimal regulation takes advantage of this additional deterrence effect by using a very strict internal control standard and an intermediate penalty that is only levied in the event of accounting manipulation. Overall, we rationalize why the commitment to lenient enforcement of internal control regulation is optimal.

Statistical Arbitrage and Securities Prices

This article introduces the concept of a statistical arbitrageopportunity (SAO). In a finite-horizon economy, a SAO is a zero-costtrading strategy for which (i) the expected payoff is positive,and (ii) the conditional expected payoff in each final stateof the economy is nonnegative. Unlike a pure arbitrage opportunity,a SAO can have negative payoffs provided that the average payoffin each final state is nonnegative. If the pricing kernel inthe economy is path independent, then no SAOs can exist. Furthermore,ruling out SAOs imposes a novel martingale-type restrictionon the dynamics of securities prices. The important propertiesof the restriction are that it (1) is model-free, in the sensethat it requires no parametric assumptions about the true equilibriummodel, (2) can be tested in samples affected by selection biases,such as the peso problem, and (3) continues to hold when investors'beliefs are mistaken. The article argues that one can use thenew restriction to empirically resolve the joint hypothesisproblem present in the traditional tests of the efficient markethypothesis.
