Sharon Harrison is Professor of Economics at Barnard College. Her early research focused on general equilibrium models of the business cycle in which the equilibrium is indeterminate, and fluctuations are driven by sunspot shocks. That is, shocks that are extrinsic to the economy. These are most easily thought of as self-fulfilling expectations on the parts of agents. More recently, she has begun to think about the behavioral aspects of these self-fulfilling expectations, seeking evidence for them by carrying out experiments in the lab. Experimental work is now another main focus of her research, including experiments about the unintended consequences of policies. Learn more at
