Bank of Canada working papers are theoretical or empirical works-in-progress on subjects in economics and finance. The views expressed in this paper are those of the authors. No responsibility for them should be attributed to the Bank of Canada. Abstract This paper studies the welfare costs and the redistributive effects of inflation in the presence of idiosyncratic liquidity risk, in a micro-f...

This paper studies optimal monetary policy when a central bank faces uncertainty about the production technology. Our model contains nominal wage and price rigidity and is sufficiently rich to capture the empirical response of aggregate variables to a monetary shock. In this economy, introducing uncertainty of the form developed in Hansen and Sargent (2003) attenuates the central bank’s optimal...

we compare alternative monetary policies for iranian economy that this paper compares alternative monetary policy rules for iranian economy in faces to both internal and external shocks. for this purpose, we investigate the responses of macroeconomic variables respected to the money base and the terms of trade shocks, under three types of monetary rules including fixed exchange rate, inflation ...

developing countries, including iran, have a high degree of volatility of macroeconomic variables. fluctuations inex change rate, bank interest rate and inflation rate can create insecure environment for in vestorsin iran. hence, this study examined the impact of macroeconomic variables on the tobin’s q index for the sugar companies of tehran stock exchange (tse) during the period between1380-1...

I develop an extension of the standard New Keynesian model to monetary policy regime switching to study the impact of uncertainty around the future inflation target. First, I fully characterize how the responses of current inflation and output to inflation target uncertainty depend on the monetary policy rule. If monetary policy is passive, inflation may increase far beyond the anticipated incr...

This paper studies the implications of certain kinds of uncertainty for monetary policy. It first describes the optimum policy rule in a simple model of the transmission mechanism as in Ball and Svensson. It then examines how this rule ought to be modified when there is uncertainty about the parameters, about the time lags, or about the nature of shocks. The paper also discusses the case of a s...

Recent studies by Gali and Gertler (1999) and Sbordone (2002) conclude that a theoretical inflation series implied by the forward-looking New Keynesian pricing model of Calvo (1983) fits post-1960 U.S. inflation closely. Their theoretical inflation series is conditional on (i) a reduced-form forecasting process for real marginal cost; and (ii) the calibration of the structural pricing equation ...

A model independent analysis shows that the running of the spectral index of the three year WMAP results can be nicely realized in noncommutative inflation. We also reexamine some concrete noncommutative inflation models. We find that a large tensor-scalar ratio is required, corresponding to a low number of e-folds before the end of inflation in some simple models. An epoch of accelerated expan...
