I recently saw the movie, Margin Call, which is currently playing in theaters and is available on demand at Comcast. There are curretly 34 reviews of it by viewers at imdb, where it has a rating of 7.3 out of 10.

I also just finished reading this paper, Fear, Greed, and Financial Crisis: A Cognitive Neuroscience Perspective, prepared for a forthcoming handbook on systemic risk. This chapter is by finance professor Andrew Lo, who is the director of the MIT laboratory for financal engineering. He also wrote another excellent paper which Glom readers are likely to find of interest, namely Reading About the Financial Crisis: A 21-Book Review, that was prepared for the Journal of Economic Literature.

In the interests of full disclosure, I taught at Temple law school a seminar titled Law, Emotions, and Neuroscience and co-taught at Yale law school with professor Dan Kahan a seminar titled Neuroscience and the Law. The seminars covered some basic materials about affective,cognitive, and social neuroscience before analyzing the potential and limits of applications to business law, conflict resolution, criminal law, ethics,  evidence, morality, paternalism, and social policy. Media coverage of neuroscience and law has a tendency to focus almost exclusively on such controversial issues as free will and responsibility in the criminal law context. Glom readers are more likely to focus on neuroeconomics and neurofinance, two nascent fields that ask how human brains engage in JDM (Judgment and Decision Making) in general and over time and under risk in particular.

Also, as cognitive neuroscientist Michael Gazzaniga recently stated: responsibility, like generosity, love, pettiness, and suspiciousness, is a strongly emergent property, which although being derived from biological mechanisms, has fundamentally distinct properties, just like the case of ice and water. The press and the public also seem to be fascinated with very colorful fMRI brain scans because they like the idea of being as the Wall Street Journal science writer, Sharon Begley, calls them: cognitive papparazi.

My system 1 believes in synchronicity, so this post, as evidenced by its title's homage to Lo's chapter, approaches the movie Margin Call from a cognitive neuroscience perspective informed by Lo's chapter. Lo provides a brief history of what we know about brains. He then explains how fear and the amygdala can exacerbate financial crises. He also demonstrates how the reward of money appears to share the same neural system and the release of the neuortransmitter dopamine into the nucleus accumbens as these rewards do: beauty, cocaine, food, music, love, and sex.

Lo proceeds to discuss a neurophysiological explanation for Kahneman and Tversky's experiment demonstrating people's aversion to sure loss. Lo proposes a neuroscientifically informed view of rationality that differs very much from an economic rational expectations conception, with the key difference being the role that emotion plays in JDM. Lo extends his analysis from individuals to groups by explaining the neurophysiology of mirror neurons, theories of mind, social interactions, and the efficient markets hypothesis. He concludes his neuroscience survey by describing the marvels and limits of the human prefrontal cortex, also known as the "executive brain." Of particular interest to Glom readers is decision fatigue, documented recently among judges rendering favorable parole decisions around 65% of the time at the start of and close to 0% by the end of each of 3 daily sessions that were separated by 2 food breaks (a late morning snack and lunch). This empirical finding that parole rates increased after food breaks is consistent with recent experimental research finding that glucose can reverse decision fatigue and the common adage to not make important decisions when tired. 

Lo provides several practical and reasonable suggesions based upon cognitive neurosciences about how policymakers can engage in financial reform to deal with systemic risk. He concludes by advocating that financial economists utilize the great recession to re-conceptualize, rethink, and revamp neoclassical economics by forging a consilience between the neurosciences and financial economic theory. Building a deeper and better understanding of economic phenomena through improved economic models and intellectual frameworks can and should lead to a more appropriate financial regulatory infrastructure.

And now onto a few comments about the movie Margin Call. Without giving away the plot for those who may want to see it without any knowledge of its ending, this movie raises ethical and moral questions about individual versus social optimality, trading on the basis of private information, panic selling, professional codes or norms of behavior, and the costs a company may impose on society and pay to others to survive. There is certainly lots of fear and greed on display in this film. Set over the course of a day and sleepless night in NYC, the movie viscerally illustrates various forms of JDM and how individuals and groups of individuals can persevere under stress and time pressures. It is a movie that can and should provoke discussion about what could have been done differently by individuals, financial firms, and regulators. It is a film that I'm going to put on the list of movies at the start of the chapter about business law in the text, Law and Popular Culture: Text, Notes, and Questions (LexisNexis Matthew Bender, 2007) by David Ray Papke, Melissa Cole Essig, Christine Alice Corcos, Lenora P. Ledwon, Diane H. Mazur, Carrie Menkel-Meadow, Philip N. Meyer, Binny Miller, and myself that we are revising for a second edition.
