This paper provides a critique of standard theories of money, in particular those based on money as a medium of exchange. Money is important because of the relationship between money and credit. The process of judging credit worthiness, in which banks play a central role, involves the collection...

The predominant weight of the existing evidence suggests that the effects of monetary policy on real economic activity are systematic, significant, and sizeable. Yet questions remain, both about individual empirical results and, more broadly, about the different methodological approaches that...

Can nominal contracts make a difference for the neutrality of money if these arise endogenously in general equilibrium? This paper utilizes aversion of Lucas's seminal equilibrium business cycle theory to address this question. However, we depart from Lucas in assuming that (1) agents have...

Historical data and model simulations support the following conclusion. Inflation is low during stock market booms, so that an interest rate rule that is too narrowly focused on inflation destabilizes asset markets and the broader economy. Adjustments to the interest rate rule can remove this...

The paper presents a model of a monetary economy where there are differences in liquidity across assets. Money circulates because it is more liquid than other assets, not because it has any special function. There is a spectrum of returns on assets, reflecting their differences in liquidity. The...

We document that expansionary monetary policy shocks are less effective at stimulating output and investment in periods of high volatility compared to periods of low volatility, using a regime-switching vector autoregression. The lower effectiveness of monetary policy can be linked to weaker...

We explore two issues triggered by the crisis. First, in most advanced countries, output remains far below the pre-recession trend, suggesting hysteresis. Second, while inflation has decreased, it has decreased less than anticipated, suggesting a breakdown of the relation between inflation and...
