A Consistent Bootstrap Test for Conditional Density Functions with Time-Dependent Data Staff Working Paper 2001-21 Fuchun Li, Greg Tkacz This paper describes a new test for evaluating conditional density functions that remains valid when the data are time-dependent and that is therefore applicable to forecasting problems. We show that the test statistic is asymptotically distributed standard normal under the null hypothesis, and diverges to infinity when the null hypothesis is false.

Evaluating Factor Models: An Application to Forecasting Inflation in Canada Staff Working Paper 2001-18 Marc-André Gosselin, Greg Tkacz This paper evaluates the forecasting performance of factor models for Canadian inflation. This type of model was introduced and examined by Stock and Watson (1999a), who have shown that it is quite promising for forecasting U.S. inflation.

Why Do Central Banks Smooth Interest Rates? Staff Working Paper 2001-17 Gabriel Srour It is commonly observed that central banks respond gradually to economic shocks, moving the interest rate in small discrete steps in the same direction over an extended period of time. This paper examines the empirical evidence regarding central banks' smoothing of interest rates, paying particular attention to the case of Canada.

Implications of Uncertainty about Long-Run Inflation and the Price Level Staff Working Paper 2001-16 Gerald Stuber This paper surveys recent developments in the theoretical and empirical literature on the economic implications of uncertainty about the longer-term outlook for inflation. In particular, the linkages between inflation, long-run inflation uncertainty, and aggregate economic activity in industrial economies have become considerably better understood during the past decade.

L'effet de la richesse sur la consommation aux États-Unis Staff Working Paper 2001-14 Yanick Desnoyers The substantial growth in wealth over the course of the second half of the 1990s generated the equivalent of a certain level of savings, while simultaneously causing household savings rates to fall significantly. The author seeks to explain this decline in savings, observed since 1995, using the methodology developed by King, Plosser, Stock, and Watson (1991).

Predetermined Prices and the Persistent Effects of Money on Output Staff Working Paper 2001-13 Michael Devereux, James Yetman This paper illustrates a model of predetermined pricing, where firms set a fixed schedule of nominal prices at the time of price readjustment, based on the work of Fischer (1977). This type of price-setting specification cannot produce any excess persistence in a fixed-duration model of staggered prices, but we show that with a probabilistic model of price adjustment, as in Calvo (1983), a predetermined pricing specification can produce excess persistence.

Evaluating Linear and Non-Linear Time-Varying Forecast-Combination Methods Staff Working Paper 2001-12 Fuchun Li, Greg Tkacz This paper evaluates linear and non-linear forecast-combination methods. Among the non-linear methods, we propose a nonparametric kernel-regression weighting approach that allows maximum flexibility of the weighting parameters.

Gaining Credibility for Inflation Targets Staff Working Paper 2001-11 James Yetman In this paper, I consider a simple model in which agents learn about the inflation target of a central bank over time by observing the policy instrument or inflation outcomes. Measuring credibility as the distance between the perceived target and the actual target, an increase in credibility is beneficial to the central bank because it brings the policy consistent with attaining the inflation target closer to that required to attain the output target.

Testing for a Structural Break in the Volatility of Real GDP Growth in Canada Staff Working Paper 2001-9 Alexandre Debs This study tests for a structural break in the volatility of real GDP growth in Canada following the methodology of McConnell and Quiros (1998). A break is found in the first quarter of 1991.

How Rigid Are Nominal-Wage Rates? Staff Working Paper 2001-8 Allan Crawford This study examines the effect of nominal-wage rigidities on wage growth in Canada using a hazard model and micro data for union contracts. The hazard model is specified in a way that allows considerable flexibility in the shape of the estimated notional wage-change distribution.
