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'...

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...

In recent years, comparative economics experienced a revival, with a new focus on comparing capitalist economies. The theme of the new research is that institutions exert a profound influence on economic development. We argue that, to understand capitalist institutions, one needs to understand...

Adaptable property-rights institutions, we argue, foster economic development. The British example illustrates this point. Around 1700, Parliament established a forum where rights to land and resources could be reorganized. This venue enabled landholders and communities to take advantage of...

Drivers have been running an 'arms race' on American roads by buying increasingly heavy vehicles such as SUVs, vans and light trucks. Families view large vehicles as providing better protection to their own occupants if a crash occurs, but these vehicles pose an increased danger to occupants of...
