The potential conflict of interest between lawyers and clients is well known. If a lawyer is paid for his time regardless of the outcome of the case,the lawyer may wish to bring the case even when it is not in the best interest of the client, may spend more hours working on the case than the client would want, and may reject a settlement when the client would be better off if it were accepted. Alternatively, if the lawyer is compensated according to the conventional contingent fee arrangement — under which he is paid a fraction of any trial award or settlement but bears all of the cost of litigation — the lawyer may have an insufficient incentive to bring the case, may spend too little time working on it if it is brought, and may encourage a settlement when the client would be better off going to trial. In this article we propose a method of compensating lawyers that overcomes the conflict of interest between the lawyer and the client. Our system is a variation of the conventional contingent fee system, but, in contrast to that system, we would have the lawyer bear only a fraction of the cost of litigation — the same fraction that the lawyer obtains of the award or settlement. We demonstrate that when the fraction of the cost that the lawyer bears equals the fraction of the award or settlement that he obtains, he will have an incentive to do exactly what a knowledgeable client would want him to do with respect to accepting the case, spending time on the case, and settling the case. Under our modified contingent fee system, a third party would compensate the lawyer for a certain fraction of his costs, in return for which the lawyer would pay that party an up-front fee. In this way, the client would not bear any costs, even if the case is lost, just as under the conventional contingent fee system.

It is commonly thought that a lawyer working under a contingent fee arrangement has an excessive motive relative to his client's interest to settle the case, leading to a lower than desirable settlement amount and a high settlement rate. The conventional analysis that generates this conclusion omits an important consideration that if the case were to go to trial, the lawyer would spend an inadequate amount of time on it. We demonstrate that once this effect is taken into account, the lawyer could have an insufficient motive to settle, the opposite of what is usually believed. Specifically, the lawyer's settlement demand could be too high and the resulting settlement rate too low.

This article studies optimal remedies in a setting in which damages vary among plaintiffs and are difficult to determine. We show that giving plaintiffs a choice between coupons to purchase units of the defendant's product at a discount and cash - a coupon-cash remedy - is superior to cash alone. The optimal coupon-cash remedy offers a cash amount that is less than the value of the coupons to plaintiffs who suffer relatively high harm. Such a remedy induces these plaintiffs to choose coupons, and plaintiffs who suffer relatively low harm to choose cash. Sorting plaintiffs in this way leads to better deterrence because the costs borne by defendants (the cash payments and the cost of providing coupons) more closely approximate the harms that they have caused.

Privacy and cybercrime law in the United States typically focuses on disclosure and deter-

rence by denial, but obtaining evidence about this regime's ecacy has eluded policymakers

and researchers. This dissertation evaluates various pieces of U.S. data protection law, and

oers data-driven approaches to longstanding questions in the literature. Chapter 2 reframes

cybercrime from a causal question to a predictive one, and presents a machine learning model

that predicts which publicly traded companies are likely to suer data breaches. Chapter

3 examines state data breach notication laws, the primary mechanism for responding to

data breaches in the U.S., and oers evidence about their eect on medical identity theft

rates. Chapter 4 looks at how governments, intellectual property owners, and technology

companies police cybercrime by disrupting cybercriminals' access to intermediaries. Taken

together, the three chapters suggest a path forward for researching and evaluating cybercrime

policy in a data-driven manner.

Consumers injured by price overcharges often are awarded coupons that can be used for a limited period of time to purchase the good at a price below that which prevails after the overcharge has been eliminated. Coupon remedies cause a deadweight loss by inducing excessive consumption by consumers with relatively low demand during the remedy period. The magnitude of the loss can be comparable to that caused by the price overcharge. As demand variability goes to zero, the deadweight loss from coupon remedies goes to zero. Eliminating the expiration date for the use of coupons does not eliminate the loss.

This article evaluates two different remedies for consumers who have been injured by a price overcharge on the sale of a good. Under a coupon remedy, injured consumers are awarded coupons that can be used for a limited period of time to purchase the good at a price below that which prevails after the overcharge has been eliminated, that is, below the competitive price. Under a discount remedy, any consumer, without proof of injury, may purchase the good for a limited period of time at a price that is set below the competitive price. Both remedies generally cause consumers to buy an excessive amount of the good during the remedy period. Under the coupon remedy only a subset of consumers are affected in this way (those holding a relatively high number of coupons), while under the discount remedy all consumers are affected. We show nonetheless that the resulting deadweight loss could be lower under the discount remedy. We also consider how the deadweight loss changes when the length of the remedy period is increased.

It is commonly thought that a lawyer working under a contingent fee arrangement has an excessive motive — relative to his client’s interest — to settle the case, leading to a lower-than-desirable settlement amount and a high settlement rate.
