Debates about the nature and economic role of money are mostly informed by evidence from the 20th century, but money has existed for millennia. We argue that there are many lessons to be learned from monetary history that are relevant for current topics of policy relevance. The past acts as a...

When agents are liquidity constrained, two options exist - sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government (outside) bonds and in the other they can borrow by issuing (inside) bonds. All transactions are voluntary, implying no...

Monetary and fiscal policy do not determine the stochastic path of prices: in the absence of financial policy, there remains indeterminacy indexed by an arbitrary probability measure over the set of states of the world. With an interest rate policy, and only if the asset market is complete,...

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...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

Milton Friedman's contributions to and influence on macroeconomics are discussed, beginning with his work on the consumption function and the demand for money, not to mention monetary history, which helped to undermine the post World War 2 Keynesian consensus in the area. His inter-related...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

This paper explores the influence of wage and price staggering on monetary persistence. First, our analysis indicates that the degree of monetary persistence generated by wage vis-à-vis price staggering depends on the relative competitiveness of the labor and product markets. We show that the...
