The legal notion of damages requires to compare the actual value of the creditor's assets with the hypothetical value that would have prevailed if the debtor had met his obligation. Moreover, values and causation may be uncertain. If nature's contribution is modelled as a random move then the...

The present paper examines an injurer causing a temporary blackout to a firm as the primary victim but also affecting customers and competitors of the firm.

In response to disparate ad hoc rules that have emerged from legal practice in Europe, the present paper proposes a unifying principle to handle such cases. Quite generally, the purpose of a damages award is to compensate the...

While various liability rules of tort law provide efficient incentives to invest, breach remedies of contract law are claimed to be distortive. Since, at least in Germany, obligations law provides general rules for both contractual and tort relationships such discrepancy seems puzzling. The...

The circular economy is a core approach driving innovative economic solutions. Although the legal system should support the development of such an economy, scientific methods to assess the environmental impact of legal rules are lacking. Legislators and scholars have highlighted consumer law as...

Under common law, the standard remedy for breach of contract is expectation damages. Under continental law, the standard is specific performance. The common law solution is ex post efficient. But is it also ex ante efficient? We use experimental methods to test whether knowing that...

Public goods are dealt with in two literatures that neglect each other. Mechanism design advises a social planner that expects individuals to misrepresent their valuations. Experiments study the provision of the good when preferences might be non-standard. We introduce the problem of the...
