At the risk of some oversimplification, the leading alternatives to the neoclassical / real business cycle model for understanding short run fluctuations are Keynesian models. I phrase this in the plural because there are multiple different versions of the Keynesian model, which differ in terms of how the aggregate supply block of the economy is formulated. Whereas neoclassical models emphasize...

The stability properties of a macromodel are determined by its characteristic roots. Conventional price level determinacy is achieved by imposing restrictions on policy rules so that the characteristic roots satisfy a saddlepath criterion. This paper shows how to choose arbitrary roots for the canonical New Keynesian macromodel using a simple forward-looking Taylor-type policy rule. We are able...

The aim of this paper is to give an account of the unfolding of macroeconomics from Keynes to the present day. To this end, I use a grid of analysis resulting from the combination of two distinctions. The first is the Marshall-Walras divide, the second is the distinction between the Keynesian conceptual apparatus and the Keynesian policy cause. On the basis of these distinctions, I construct tw...

The New Keynesian sticky-price model has become increasingly popular for monetary-policy analysis. However, there have been conflicting results on the empirical performance of the model. In this paper, I attempt to reconcile these conflicting claims by examining various specifications of the model within the context of a single framework. I find that the New Keynesian model does not fit the U.S...

Price rigidity is the key mechanism for propagating business cycles in traditional Keynesian theory. Yet the New Keynesian literature has failed to show that sticky prices by themselves can e¤ectively propagate business cycles in general equilibrium. We show that price rigidity in fact can (by itself) give rise to a strong propagation mechanism of the business cycle in standard New Keynesian mo...

One of the most significant changes in monetary economics at beginning twenty-first century has been virtual disappearance what was once a dominant focus, role money policy, and parallelly, liquidity preference-money supply (LM) curve. Economists used to consider policy with help LM curve as part analytical framework which captures demand for money. However, workhorse model modern theory New Ke...

We[1] present estimates of the Elasticity of Intertemporal Substitution (EIS) for Iranian households using synthetic cohort panels based on household micro-data. Results show significant difference with the common values used in Dynamic Stochastic General Equilibrium (DSGE) models which are originally based on estimated values for developed countries. We show that this difference has important ...

The notion of " Islamic finance " was born during the tumultuous identity-politics years of the mid-twentieth century. Indian, Pakistani, and Arab thinkers contemplated independence from Britain, and independence of Pakistan from India, within a context of " Islamic society. " Islam was assumed to inspire political, economic, and financial systems that are distinctive and independent of the Wes...
