The macroeconomic costs of disinflation are considered for the United States in a rational expectations macroeconometric model with sticky prices and imperfect information regarding monetary policy objectives. The analysis centers on simulation experiments using the Board’s new quarterly...

This paper establishes that when equations connecting coefficients from reduced forms with their structural counterparts are inconsistent, a necessary and sufficient condition standard in econometric textbooks for the identifiability of coefficients in linear simultaneous equations systems is...
