We develop a tractable method for augmenting macroeconomic models with autonomous variation in higher-order beliefs. We use this to accommodate a certain type of waves of optimism and pessimism that can be interpreted as the product of frictional coordination and, unlike the one featured in the...

We show that international trade in goods is the main determinant of international equity portfolios and offers a compelling -- theoretically and empirically -- resolution of the portfolio home bias puzzle. The model implies that investors can achieve full international risk diversification if...

The two leading explanations for the poor inflation performance during the 1970s are policy opportunism (Barro and Gordon 1983) and "inadvertently" bad monetary policy (Clarida, Gali, and Gertler 2000, Orphanides 2003). The main models of the latter category are that of Orphanides (loose...

We revisit the contribution of misperceived money to business cycles, and in particular to the inertial dynamics of inflation following a monetary policy shock. We establish three things. First, the difference between preliminary and revised money data captures monetary misperceptions well....

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...

The Calvo scheme represents the standard specification of price resetting in the New Keynesian model. We show that using this rather than a fixed duration (Taylor) scheme matters importantly for the dynamics of the model as it allows it to generate hump-shaped response of output without an...
