Existing theories advocate the exclusive use of equity-like instruments in executive compensation. However, recent empirical studies document the prevalence of debt-like instruments such as pensions. This paper justifies the use of debt as efficient compensation. Inside debt is a superior...

This paper studies the value of more precise signals on agent performance in an optimal contracting model with endogenous effort. With limited liability, the agent's wage is increasing in output only if output exceeds a threshold, else it is zero regardless of output. If the threshold is...

The informativeness principle demonstrates that a contract should depend on informative signals. This paper studies how it should do so. Signals that indicate the output distribution has shifted to the left (e.g. weak industry performance) reduce the threshold for the manager to be paid; those...

Existing theories of debt consider a single contractible performance measure ("output"). In reality, many other performance signals are also available. It may seem that debt is no longer optimal; for example, if the signals are sufficiently positive, the agent should receive a payment even if...

This paper studies optimal executive pay when the CEO is concerned about fairness: if his wage falls below a perceived fair share of output, the CEO suffers disutility that is increasing in the discrepancy. Fairness concerns do not lead to fair wages always being paid -- to induce effort, the...

This paper studies the effect of stock liquidity on blockholder governance. Conditional upon acquiring a stake, liquidity reduces the likelihood that a blockholder governs through voice (intervention) – as shown by the greater propensity to file Schedule 13Gs (passive investment) than 13Ds...

This paper studies optimal contracting under synergies. We define influence as the extent to which effort by one agent reduces a colleague's marginal cost of effort, and synergy to be the sum of the (unidimensional) influence parameters across a pair of agents. In a two-agent model, effort...

The informativeness principle demonstrates qualitative benefits to increasing signal precision. However, it is difficult to quantify these benefits -- and compare them against the costs of precision -- since we typically cannot solve for the optimal contract and analyze how it changes with...

This paper studies multi-agent optimal contracting with cost synergies. We model synergies as the extent to which effort by one agent reduces his colleague's marginal cost of effort. An agent's pay and effort depend on the synergies he exerts, the synergies his colleagues exert on him and,...

This paper shows that the informativeness principle, as originally formulated by Holmstrom (1979), does not hold if the first-order approach is invalid. We introduce a "generalized informativeness principle" that takes into account non-local incentive constraints and holds generically, even...
