In this article I first describe the basic principles that parents employ in disciplining their children. The description is based on a survey of parents, the major results of which are that parental sanctions are premised on wrongdoing--not on the mere causation of harm; that parental sanctions...

We use NOMINATE (Nominal Three Step Estimation) (Poole and Rosenthal, 1983, 1997) to estimate ideal points for all Supreme Court Justices in Brazil from 2002 to 2012. Based on these estimated preferences we identify the nature of the two main dimensions along which disagreements tend to occur in...

This paper develops a general model of anticommons fragmentation in property. Using several related examples, we consider the equilibria obtained under different scenarios. The various illustrations are later utilized to develop a model of fragmented property. The model reveals that the private...

We develop a theoretical model of, and provide the first large-sample evidence on, the behavior and impact of non-practicing entities (NPEs) in the intellectual property space. Our model shows that NPE litigation can reduce infringement and support small inventors. However, the model also shows...

We provide theoretical and empirical evidence on the evolution and impact of non-practicing entities (NPEs) in the intellectual property space. Heterogeneity in innovation, given a cost of commercialization, results in NPEs that choose to act as "patent trolls" that chase operating firms'...

This paper analyzes how private decisions and public policies are shaped by personal and societal preferences ("values"), material or other explicit incentives ("laws") and social sanctions or rewards ("norms"). It first examines how honor, stigma and social norms arise from individuals'...

Many states have recently changed their scope of practice laws and granted full practice authority to nurse practitioners, allowing them to practice without oversight from physicians. Physician groups have argued against this change, citing patient safety concerns. In this paper, we use a...

The primary causal requirement that must be met for a negligent party to be held liable for a harm is a demonstration that the harm would not have occurred if the party had not been negligent. Thus, for a speeding driver to be found liable for harm done in a car accident, it must be shown that...

When do policies generate expressive or backlash effects? Recent economic models suggest that where a proscribed activity is prevalent, permissive laws liberalize attitudes toward partakers while increasing utility. The opposite occurs in communities where the proscribed activity is rare. To...
