I examine the implementation of the Friedman rule under the assumption that age dependent lump sum transfers are possible and private intermediation is costly. This is done both in an infinitely lived agents model and in an overlapping generations model. I argue that in addition to a zero...

We study price determination and exchange patterns in a monopolistically competitive economy, in which both goods and (fiat) money are perfectly divisible. The decentralized trading environment features 'multiple matches,' in which households consume bundles of commodities and have a preference...

I examine the argument that a low interest rate policy can lead to "overvalued" private assets or privately created bubbles (private bubbles). Using the standard approach to bubbles, I find that a policy of a low real interest rate may support private bubbles but a policy of a low nominal...

I use the Baumol-Tobin approach to examine the following propositions: (a) The optimal supply of liquidity requires a government loan program in addition to paying interest on reserves held by banks, (b) The adoption of the optimal policy will crowd out private credit arrangement and will thus...

This paper examines how and to what extent parameter estimates can be biased in a dynamic stochastic general equilibrium (DSGE) model that omits the zero lower bound (ZLB) constraint on the nominal interest rate. Our Monte Carlo experiments using a standard sticky-price DSGE model show that no...

We argue that nonhomothetic preferences with habit formation in nondurable and durable consumption can be a driving force behind sectoral comovement in production. We make this point by augmenting a two-sector New Keyesian model a la Barsky, House and Kimball (2007) with these two real features...
