I show that long-run risk - highly persistent variation in expected consumption growth - arises endogenously in a production economy with nominal frictions. The `long-run' part comes from price stickiness. Nominal frictions in the model generate a consumption growth process that shows low persistence unconditionally, but has a highly persistent conditional mean. The `risk' part comes from Epstein-Zin preferences, which result in a large risk premium being associated with variation in the conditional mean. The model provides new testable implications for long-run-risk models, and restricts the joint distribution of consumption and nominal equity and bond risk premia. A calibrated version of the model generates consumption, a risk-free interest rate, and equity risk premium behavior that are consistent with U.S. data.
