We analyze the role of implicit contracts' (that is, informal agreements supported by" reputation rather than law) both within firms, for example in employment relationships between them, for example as hand-in-glove supplier relationships. We find that the optimal" organizational form is...

Objective measures of performance are seldom perfect. In response, incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures. This paper explores the combined use of subjective and objective performance measures...

We analyze a rational-expectations model of information acquisition and price formation in an intermediate- good market: prices and net supply are non-negative, there are no noise traders, and the intermediate good has multiple potential uses. Several of our results differ from the classic...

We analyze a rational-expectations model of price formation in an intermediate-good market under uncertainty. There is a continuum of dyads, each consisting of an upstream party and a downstream party. Both parties can make specific investments at private cost, and there is a machine that either...

Physicians prescribing drugs for patients with schizophrenia and related conditions are remarkably concentrated in their choice among antipsychotic drugs. In 2007 the single antipsychotic drug prescribed by a physician accounted for 66% of all antipsychotic prescriptions written by that...

Although exercise prices for executive stock options can be set either below or above the grant-date market price, in practice virtually all options are granted at the money. We offer an economic rationale for this apparent puzzle, by showing that pay-to-performance incentives for risk-averse...

The trouble with options is that too many options are granted to too many people. Most options are granted below the top-executive level, and options are often an inefficient way to attract, retain and motivate executives and (especially) lower-level employees. Why, then, are options so...

We employ a certainty-equivalence framework to analyze the cost and value of, and pay/performance incentives provided by, non-tradable options held by undiversified, risk-averse executives. We derive Executive Value' lines, the risk-adjusted analogues to Black-Scholes lines, and distinguish...

Investment decisions require trading off current expenditures against future revenues. If revenues extend far enough into the future, the executives responsible for designing long-run investment policy may no longer be in office by the time all the revenues are realized. We present evidence...

This paper studies career concerns -- concerns about the effects of current performance on future compensation -- and describes how optimal incentive contracts are affected when career concerns are taken into account. Career concerns arise frequently: they occur whenever the market uses a...
