Channel systems for conducting monetary policy are becoming increasingly popular. Despite their popularity, the consequences of implementing policy with a channel system are not well understood. We develop a general equilibrium framework of a channel system and investigate the optimal policy. A...

This paper extends the discussion of the relationship between Bayesian stability and Bayesian efficiency in Liu(2020). We focus on the worst possible case for workers, in which firms offer workers wages exactly opposite to workers’ initial payoffs, so that workers will always enjoy a zero...

Rational expectations has been the dominant way to model expectations, but the literature has quickly moved to a more realistic assumption of boundedly rational learning where agents are assumed to use only a limited set of information to form their expectations. A standard assumption is that...

We develop a dynamic stochastic general equilibrium model with rational inattention by households and firms. Consumption responds slowly to interest rate changes because households decide to pay little attention to the real interest rate. Prices respond quickly to some shocks and slowly to other...

DSGE-models have become important tools of analysis not only in academia but increasingly in the board rooms of central banks. The success of these models has much to do with the coherence of the intellectual framework it provides. The limitations of these models come from the fact that they...

Central bank independence is a common feature in advanced economies. Delegation of monetary policy to an independent central bank with a clear mandate for price stability has proven to be successful in keeping a check on inflation and providing a trusted currency. However, it is also a fact that...

This paper analyses in a simple global games framework welfare effects of different communication strategies of a central bank: it can either publish no more than its overall assessment of the economy or be more transparent, giving detailed reasons for this assessment. The latter strategy is...

We derive the optimal monetary policy in a sticky price model when private agents follow adaptive learning. We show that this slight departure from rationality has important implications for policy design. The central bank faces a new intertemporal trade-off, not present under rational...

We develop a behavioral macroeconomic model in which agents use simple but biased rules to forecast future output and inflation. This model generates endogenous waves of optimism and pessimism (Animal Spirits") that are generated by the correlation of biased beliefs. We contrast the dynamics of...
