What generates persistence in inflation? Is inflation persistence structural? This paper investigates learning as a potential source of persistence in inflation. The paper focuses on the price-setting problem of firms and presents a model that nests structural sources of persistence (indexation)...

Factor-augmented VARs (FAVARs) have combined standard VARs with factor analysis to exploit large data sets in the study of monetary policy. FAVARs enjoy a number of advantages over VARs: they allow a better identification of the monetary policy shock; they can avoid the use of a single variable...

This paper presents an estimated model with learning and provides evidence that learning can improve the fit of popular monetary DSGE models and endogenously generate realistic levels of persistence. The paper starts with an agnostic view, developing a model that nests learning and some of the...

This paper estimates a DSGE model with learning to re-examine the evidence on time variation in post-war U.S. monetary policy. Several papers document a regime switch, by showing that policy changed from `passive' and destabilizing in the pre-1979 period to `active' and stabilizing in the...

Using an optimisation-based model with endogenous labour supply and a proportional tax rate, we compare the stabilising properties of different fiscal policy rules. The economy is affected by shocks from both government spending and technology. The fiscal policy rule can be based on government...

The aim of this study is to identify the extent to which the GCC countries can adopt similar economic policies by the time of the formation of the GCC unified currency in 2010. Among many other convergence standards, the study suggests to examine the economic structure of the GCC countries to...

We analyze the microfoundations for Keynesian aggregate demand effects by considering the link between aggregate demand and firm production decisions under monopolistic competition. Macroeconomic equilibrium is characterized in a simple graphical framework that facilitates comparison of several...

In this paper, we present an alternative approach to inflation and inflation measurement based on Menger’s theory of inner exchange value of money and on the stochastic approach to index numbers. We briefly describe the characteristics of the sample cross-section distribution of price changes....

Recent empirical results about the US term structure are difficult to reconcile with the classical hypothesis of rational expectations even if time-varying but stationary term premia are allowed for. A hypothesis of rational learning about the conditional variance of the log pricing kernel is...

This paper analyzes qualitatively and quantitatively the e ects of declining mortality rates on fertility, education and economic growth. The analysis demonstrates that if individuals are prudent in the face of uncertainty about child survival, a decline in an exogenous mortality rate reduces...
