Midbrain Mutiny

Book excerpt: An analysis of how economic theories can be used to understand disordered and pathological gambling that calls on empirical evidence about behavior and the brain and argues that addictive gambling is the basic form of all addiction. The explanatory power of economic theory is tested by the phenomenon of irrational consumption, examples of which include such addictive behaviors as disordered and pathological gambling. Midbrain Mutiny examines different economic models of disordered gambling, using the frameworks of neuroeconomics (which analyzes decision making in the brain) and picoeconomics (which analyzes patterns of consumption behavior), and drawing on empirical evidence about behavior and the brain. The book describes addiction in neuroeconomic terms as chronic disruption of the balance between the midbrain dopamine system and the prefrontal and frontal serotonergic system, and reviews recent evidence from trials testing the effectiveness of antiaddiction drugs. The authors argue that the best way to understand disordered and addictive gambling is with a hybrid picoeconomic-neuroeconomic model.
