This paper introduces dynamic predictor selection into a New Keynesian model with heterogeneous expectations and examines its implications for monetary policy. We extend Branch and McGough (2006) by endogenizing the fraction of rational versus adaptive agents along the lines of Brock and Hommes (1997). We show that models that are determinate under the assumption of full rationality may possess...

We propose an Economic Stability Index (ESI) incorporating house prices and stock prices as components of the measure of the inflation rate in order to allow the European Central Bank (ECB) to achieve both price and macroeconomic stability. We use an optimisation approach to estimate target weights for different sectoral prices in the broader price index, which depend on sectoral parameters oth...

This paper studies long-run inflation targets and stability in an imperfect information environment. When central banks set an inflation target that is not fully communicated, agents draw inferences about inflation from recent data and remain alert to structural change in their econometric model by forming expectations from a forecasting model that is estimated via discounted least squares. Inf...

We examine whether there is a case for coordinating monetary policy reactions across major economies. We undertake stochastic simulations on the National Institute’s Global Ž . Econometric Model NiGEM , to evaluate independently set monetary policy where domestic considerations remain the prime objective and we compare outcomes to a regime with a coordinated policy where domestic interest rates...

We analyze a simple strategic model of interaction between central bank and labor union. We assume that the intransparency of the central bank (labor union) induces Knightian uncertainty faced by the labor union (central bank). Knightian uncertainty means that decision makers are unable to make exact probability judgements. It is modelled by Choquet Expected Utility Theory and its recent applic...

We explore the connection between shock observability and equilibrium. When aggregate shocks are unobserved the rational expectations solutions remain unchanged if contemporaneous aggregate outcomes are observable, but their stability under adaptive learning must be reconsidered. We obtain learning stability conditions and show that, provided there is not large positive expectational feedback, ...

A key variable for the conduct of monetary policy is the natural rate of interest – the real interest rate consistent with output equaling potential and stable inflation. Economic theory implies that the natural rate of interest varies over time and depends on the trend growth rate of output. In this paper we apply the Kalman filter to jointly estimate the natural rate of interest, potential ou...

Monetary environment as the core of financial system has been functionally designed in light of the new set of extensive goals including financial stability, sustainable noninflationary growth, external sustainability, and price stability. A comprehensive monetary policy framework is proposed for Iran which systematically include the new goals, stance variables, instruments, transmission mechan...

â â â  â â â â â  the aim of this paper is to simulate the effects of some macroeconomic policy tools on production and inflation of iran by the current worldwide financial and real crisis. the theoretical framework of the analysis is based on the so-called ‘imf/world bank integrated model’ which is the synthesis (a merger) of the basic monetary approach of the balance of payments used at t...

This paper examines the role of economic freedom in the empirical relationship between business cycle volatility and long-run growth across countries. In a diverse sample of 99 countries, it is shown that accounting for economic freedom’s influence on volatility mitigates or even eliminates the negative impact of volatility on growth. It is also possible that the impact of volatility on growth ...
