We begin by showing how heterogeneity in terms of risk tolerance can cause financial markets to propagate transitory shocks and induce higher output volatility, albeit with a higher mean. We then show how this simple heterogeneous agent framework can explain an expansion driven by the growth in consumer debt, and why the equilibrium path of such an economy is likely fragile. In particular, we demonstrate that the emergence of a small amount of asymmetric information can make the economy susceptible to changes in expectations that can induce large reversals of financial flows, the freezing of assets and a recession that can persist despite high productivity.
