The authors examine the evidence presented by Galí and Gertler (1999) and Galí, Gertler, and Lopez-Salido (2001, 2003) that the inflation dynamics in the United States can be well-described by the New Keynesian Phillips curve (NKPC).

Inflation forecasting is fundamental to monetary policy. In practice, however, economists are faced with competing goals: accuracy and theoretical consistency.

This paper investigates the question of whether a transition to a low-inflation environment, induced by a shift in monetary policy, results in a decline in the degree of pass-through of exchange rate movements to consumer prices.

Economists' long-standing interest in the degree to which exchange rate movements are reflected in prices was rekindled in the 1970s by a combination of rising inflation and the adoption of more flexible exchange rate regimes in many industrialized countries. Specifically, there were concerns that a large currency depreciation could degenerate into an inflationary spiral. Such fears were curtailed in the 1980s and early 1990s as industrialized countries began to reduce and stabilize their inflation rates. The low-inflation period most industrialized countries entered approximately a decade ago coincided with significant exchange rate depreciations that had much smaller effects on consumer prices than expected. This led to a belief that the extent to which exchange rate movements are passed through to consumer prices has declined. In this article, the authors examine why pass-through could be incomplete and review empirical estimates to determine whether pass-through has indeed declined, suggesting possible reasons for this decline and discussing the implications for monetary policy.

The authors use simple new finite-sample methods to test the empirical relevance of the New Keynesian Phillips curve (NKPC) equation.

The authors develop a small open-economy dynamic stochastic general-equilibrium (DSGE) model in an attempt to understand the dynamic relationships in Canadian macroeconomic data.

For several decades, the prices of services have been rising more rapidly than the prices of goods in Canada and the other major industrialized countries. In 2002, this gap between the growth rates of these two components of the consumer price index (CPI) widened considerably, leading researchers to ask if this was the beginning of a trend. Analysis reveals, however, that the gap is based on short-term dynamics and that it appears to be independent of the trend in the development of the overall price level. Evidence also shows that the gap is eventually reabsorbed. The authors examine a number of potential causes for the prices of services to rise faster than those of goods. These include the more rapid pace of productivity growth in the goods sector, the greater openness of goods to foreign trade, and stronger growth in the demand for services.

Phillips curves are generally estimated under the assumption of linearity and parameter constancy. Linear models of inflation, however, have recently been criticized for their poor forecasting performance.

The authors analyze exchange rate pass-through in an estimated structural model of a small open economy that incorporates three types of nominal rigidity (wages and the prices of domestically produced and imported goods) and eight different structural shocks. The model is estimated using quarterly data from Canada and the United States.

The authors apply existing inflation models that have worked well in industrialized countries to Mexico, an emerging market that has recently moved to adopt an inflation-targeting framework for monetary policy. They compare the performance of these models with a mark-up model that has been used extensively to analyze inflation in Mexico.
