Will Global Demand for Oil Peak This Decade?

by Alvin Powell, Harvard Gazette

The International Energy Agency expects the world's oil demand to start to ebb in the coming years. However, Joseph Lassiter and Lauren Cohen say the outlook will likely be more complex, especially as poor and fast-growing regions seek energy sources for their economies.

Can Robin Williams’ Son Help Other Families Heal Addiction and Depression?

Re: Lauren H. Cohen

Zak Pym Williams, son of comedian and actor Robin Williams, had seen how mental health challenges, such as addiction and depression, had affected past generations of his family. Williams was diagnosed with generalized anxiety disorder, depression, and post-traumatic stress disorder (PTSD) as a young adult and he wanted to break the cycle for his children. Although his children were still quite young, he began considering proactive strategies that could help his family’s mental health, and he wanted to share that knowledge with other families. But how can Williams help people actually take advantage of those mental health strategies and services? Professor Lauren Cohen discusses his case, “Weapons of Self Destruction: Zak Pym Williams and the Cultivation of Mental Wellness.”

Patent Trolls

by Lauren Cohen, Umit G. Gurun & Scott Duke Kominers

Clearly defined property rights are essential for well-functioning markets. In the case of intellectual property (IP), however, property rights are complex to define; unlike ownership of physical assets, the space of ideas is difficult to clearly delineate. A solution employed by the United States and many other countries is the patent-a property right allowing an idea's owner sole commercialization rights for a period of time. A new organizational form, the non-practicing entity (NPE), has recently emerged as a major driver of IP litigation. NPEs amass patents not for the sake of producing commercial products, but in order to prosecute infringement on their patent portfolios. In this paper the authors provide the first large-sample evidence on the litigation behavior of NPEs. They show precisely which corporations NPEs target, when NPEs litigate, and how NPE litigation impacts the innovative activity of targeted firms. NPEs behave, on average, as patent trolls. This means that NPEs target firms that are flush with cash or that have just had positive cash shocks. NPEs even target conglomerate firms that earn their cash from segments having nothing to do with their allegedly infringing patents. The stakes of how to organize intellectual property disputes are massive. If the United States becomes a less desirable place to innovate because NPEs are left unchecked, innovation and human capital, and the returns to that innovation and human capital, will likely flee overseas. But innovators will also leave if they feel they are not are protected from large, well-funded interests that might infringe on innovative capital without recourse. Key concepts include: The rise of non-practicing entities (NPEs) has sparked a debate regarding their value and their impact on innovation. This study provides evidence that NPEs do not protect innovators from large interests in the intellectual property space. On average, NPEs behave as patent trolls that chase cash and negatively impact future innovation. Policy should be to more carefully limit the power of NPEs or, in the framework of the authors' model, increase the cost of bringing suit against commercializers of innovative ideas.

Playing Favorites: How Firms Prevent the Revelation of Bad News

by Lauren Cohen, Dong Lou & Christopher Malloy

Given the current regulatory environment in the United States (and increasingly globally) of level playing-field information laws, firms can only communicate information in public exchanges. However, even in these highly regulated venues, there are subtle choices that firms make that reveal differential amounts of information to the market. In this paper the authors explore a subtle but economically important way in which firms shape their information environments, namely through their specific organization and choreographing of earnings conference calls. The analysis rests on a simple premise: firms understand they have an information advantage and the ability to be strategic in its release. The key finding is that firms that manipulate their conference calls by calling on those analysts with the most optimistic views on the firm appear to be hiding bad news, which ultimately leaks out in the future. Specifically, the authors show that "casting" firms experience higher contemporaneous returns on the (manipulated) call in question, but negative returns in the future. These negative future returns are concentrated around future calls where they stop this casting behavior, and hence allow negative information to be revealed to the market. Key concepts include: The paper shows new evidence on a channel through which firms influence information disclosure even in level-playing-field information environments. The pattern of firms appearing to choreograph information exchanges directly prior to the revelation of negative news is systematic across the universe of firms. Closed for comment; 0 Comments.
