Imperfect Information and the Business Cycle
Imperfect information has played a prominent role in modern business cycle theory. We assess its importance by estimating the New Keynesian (NK) model under alternative informational assumptions. One version focuses on confusion between temporary and persistent disturbances. Another, on unobserved variation in the inflation target of the central bank. A third on persistent misperceptions of the state of the economy (measurement error). And a fourth assumes perfect information (the standard NK-DSGE version). We find that imperfect information contains considerable explanatory power for business fluctuations. Signal extraction seems to provide a conceptually satisfactory, empirically plausible and quantitatively important business cycle mechanism.
