Measuring Macroeconomic Uncertainty: US Inflation and Output Growth

We find that model estimates of the term structure of ex ante or perceived macro uncertainty are more in line with realized uncertainty than survey respondents' perceptions for both inflation and output growth. Survey estimates contain short-term vari- ation in short-horizon uncertainty which is less evident in the model-based estimates. We consider the extent to which these short-term variations coincide with short-term movements in stock market uncertainty.
