We introduce a model of the economy as a social network. Two agents are linked to the extent that they transact with each other. This generates well-defined topological notions of location, neighborhood and closeness. We investigate the implications of our model for monetary economics. When a...

Taylor rules posit a linear relationship between the output gap, inflation, and short-term nominal interest rates. Previous work has shown that the relationship between these key economic variables as captured by the Taylor rule is quite robust both across countries and monetary policy regimes....

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,...

We consider a cash-in-advance economy under uncertainty in which monetary policy sets either short-term nominal interest rates or money supplies. We show that both the initial price level and the distribution of the inflation rate up to its expectation are indeterminate, regardless of the degree...

Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and a complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances. Competitive...

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...

The general equilibrium model with incomplete financial markets (GEI) is extended by adding fiat money, fiscal and monetary policy and a cash-in-advance constraint. The central bank either pegs the interest rate or money supply while the fiscal authority sets a Ricardian or a non-Ricardian...

This paper investigates the possibility that wealth (holdings of money) serves as a signal of ability to produce high quality products for agents who cannot directly observe the quality of the products. A producer's wealth may advertise past success in selling products to agents who knew the...

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.

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.
