This chapter summarizes the case for considering money as a legal institution. The Western liberal tradition, represented here by John Locke’s iconic account of money, describes money as an item that emerged from barter before the state existed. Considered as an historical practice, money is...

This article offers a concise typology of spontaneous norms – i.e., norms that are formed or sustained through decentralized collective behavior in a community. The typology combines three criteria for identifying spontaneous norms: (i) implicit formation of (customary) rules, as opposed to...

This paper discusses models of law and regulation of Artificial Intelligence (“AI”). The discussion focuses on four models: the black letter model, the emergent model, the ethical model, and the risk regulation model. All four models currently inform, individually or jointly, integrally or...

This article strengthens Calabresi’s call for a bilateral relationship between law and economics with two claims. The first claim is that the fitness analysis of Law and Economics (“concept-based fitness”) requires studying legal reasons and reasoning. This is a remarkable difference with...

As is typical of a Breyer opinion, Unicolors v. H&M—the only IP decision this Term—illuminates the distinction between mistakes of fact and of law and explains the reasoning by virtue of a brief hypothetical. Imagine someone (named John) who sees a flash of red in a tree and blurts out,...

The so-called Chicago School of law and economics, which emerged in the late 1970s, was regarded by many lawyers with considerable suspicion. Much of this suspicion was due to the artificial and unrealistic nature of the assumptions about human motivation that underpinned that School’s...

Assuming that the degree of discretion granted to judges was the main distinguishing feature between common and civil law until the 19th century, we argue that constraining judicial discretion was instrumental in protecting freedom of contract and developing the market order in civil law. We...

We argue that in the development of the Western legal system, cognitive departures are the main determinant of the optimal degree of judicial rule-making. Judicial discretion, seen here as the main distinguishing feature between both legal systems, is introduced in civil law jurisdictions to...

Economists have documented pervasive correlations between legal origins, modern regulation, and economic outcomes around the world. Where legal origin is exogenous, however, it is almost perfectly correlated with another set of potentially relevant background variables: the colonial policies of...

Theory about the relevance of soft law abounds; empirical research on the topic does not. This study begins to even out this imbalance by not only developing a number of conjectures based on institutional economics, but also by testing them empirically. Based on all 2,289 soft laws concluded by...
