Changes in both the macroeconomy and in macroeconomics suggest that the IS-LM-AS model is no longer the best baseline model of short-run fluctuations for teaching and policy analysis. This paper presents an alternative model that replaces the assumption that the central bank targets the money...

This paper presents a theory of the monetary transmission mechanism in a monetary version of Farmer's (2009) model in which there are multiple equilibrium unemployment rates. The model has two equations in common with the new-Keynesian model; the optimizing IS curve and the policy rule. It...

One of the most significant changes in monetary economics in recent years has been the virtual disappearance of what was once a dominant focus on money, and in parallel the disappearance of the LM curve as part of the analytical framework that economists use to think about issues of monetary...

This paper discusses monetarist objections to the IS-LM model. We explore the views of two principal spokesmen for monetarism: Milton Friedman and the team of Karl Brunner and Allan Meltzer. Friedman did not explicitly state the reasons he generally chose not to use the IS-LM model in rejecting...

Emerging markets (sometimes endowed with fertile pampas) have limited access to world capital markets and suffer from original sin: they cannot borrow in their own currency. Does this mean that monetary and exchange rate policy has non-standard effects in such countries? We develop a simple...

Dynamic optimizing models with an IS-LM-type structure and slow price adjustments have been used for much recent monetary policy analysis, but usually with capital and investment treated as exogenous a significant restriction. This paper demonstrates that investment decisions can be endogenized...

This paper asks whether relations of the IS-LM type can sensibly be used for the aggregate demand portion of a dynamic optimizing general equilibrium model intended for analysis of issues regarding monetary policy and cyclical fluctuations. The main result is that only one change -- the addition...

This paper presents a simple synthesis of Keynesian, monetary, and portfolio approaches to macroeconomic theory under flexible exchange rates. By including the key features of all the partial approaches in a general model, we show that some of the important contrasts that have been drawn between...

This paper develops a New Keynesian model featuring financial intermediation, short and long term bonds, credit shocks, and scope for unconventional monetary policy. The log-linearized model reduces to four key equations - a Phillips curve, an IS equation, and policy rules for the short term...

Farmer, Waggoner, and Zha (2009) show that a new Keynesian model with a regime-switching monetary policy rule can support multiple solutions that depend only on the fundamental shocks in the model. Their note appears to find solutions in regions of the parameter space where there should be no...
