This paper examines the consequences of (S,s) pricing rules in a dynamic economy with heterogeneous costs of price adjustment. We construct the stationary distributions for aggregate output and prices for our model economy. As a result of our assumption of heterogeneous costs we find that: (i)...

A key argument in Caplin and Leahy (1997) states that the correlation between monetary shocks and output is falling in the variance of the money supply. We demonstrate that this conclusion depends on solving for the correlation in the non-stationary state of the model. In the stationary state,...

We study the impact of two-sided nominal shocks in a simple dynamic, general equilibrium (S,s)-pricing macroeconomic model comprised of heterogeneous sectors. The simple model we develop has a number of appealing empirical implications; it captures why some sectors of the economy have...

A stylized macroeconomic model is developed with an indebted, heterogeneous Investment Banking Sector funded by borrowing from a retail banking sector. The government guarantees retail deposits. Investment banks choose how risky their activities should be. We compared the benefits of separated...

Banks fail because of bad economic fundamentals, or panic withdrawals by depositors. We show that even though there is no need for regulation when the bank’s policy regarding its solvency is transparent, there is indeed need for regulation if there is a lack of transparency. When the bank...

We analyze the characteristics of optimal dynamics in an economy in which neither prices nor wages adjust instantaneously and lump-sum taxes are unavailable as a source of government finance. We then propose that monetar and fiscal policy should be coordinated to satisfy a pair of simple...

When the monetary authority controls the short-term interest rate we find that under a regime of permanent (and even persistent but temporary) deficits that a strict upper bound on the feasible interest rate sequence is present. More generally, the satisfaction of the fiscal authority’s...

We examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is optimal. We look at the extent to which different degrees of fiscal feedback enhances or detracts from the ability of the monetary authorities to stabilise output...

We re-examine optimal monetary policy when lump-sum taxes are unavailable. Under commitment, we show that, with alternative utility functions to that considered in Nicolini’s related analysis, the direction of the incentive to cheat may depend on the initial level of government debt, with low...

In this paper we estimate a DSGE model built along the lines of the recent Farmer¡¯s micro-foundation of the General Theory. Estimating a simple demand-driven competitive-search model, we test the ability of this new theoretical proposal to match the behaviour of the US and Euro Area...
