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,...

Until recently, much effort has been devoted to the estimation of panel data regression models without adequate attention being paid to the drivers of diffusion and interaction across cross section and spatial units. We discuss some new methodologies in this emerging area and demonstrate their...

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...

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...

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...

Stabilization policy involves joint monetary and fiscal rules. We develop a model enabling us to characterize systematic simple monetary and fiscal policy over the business cycle. We principally focus on the following question: what are the key properties of the joint simple rule governing the...

We re-investigate the delayed overshooting puzzle. We find that delayed overshooting is primarily a phenomenon of the 1980s when the Fed was under the chairmanship of Paul Volcker. Related findings are as follows: (1) Uncovered interest parity fails to hold during the Volcker era and tends to...

We study the effect of inflation on the wage dispersions due to firm heterogeneity and on-the-job search, in the context of a labour market á la Postel-Vinay and Robin (International Economic Review 43, 2002) and micro-founded money demand. The productivity distribution of firms is firstly...

Job creation and job destruction are investigated in an economy featured by search frictions in both labour and goods markets. We show that both the unemployment rate and the endogenous job destruction rate increase when the inflation rate rises, because the demand declines due to the increase...

The design and analysis of optimal monetary policy is usually guided by the paradigm of homogeneous rational expectations. Instead, we examine the dynamic consequences of implementation strategies, when the actual economy features expectational heterogeneity. Agents have either rational or...
