Given the frequency of price changes, the real effects of a monetary shock are smaller if adjusting firms are disproportionately likely to be ones with prices set before the shock. This selection effect is important in a large class of sticky-price models with time-dependent price adjustment. We...

The Median CPI is well-known as an accurate predictor of future infl ation. But it’s just one of many possible trimmed-mean inflation measures. Recent research compares these types of measures to see which tracks future inflation best. Not only does the Median CPI outperform other trims in...

We introduce inventories into an otherwise standard New Keynesian model and study the implications for inflation dynamics. Inventory holdings are motivated as a means to generate sales for demand-constrained firms. We derive various representations of the New Keynesian Phillips curve with...

It has often been reported that different demographic groups show persistent differences in their inflation expectations. Some reasonable explanations have been suggested, but most have failed to fully explain these apparent differences. We argue that the demographic differences have been...

Do the rising commodity prices we have seen in recent years reflect basic supply-and-demand developments in various commodity markets, or are they the fi rst signs of inflation? In practice, it’s not always easy to tell the difference - for the public or policymakers - but fundamentally...

We study discretionary equilibrium in the Calvo pricing model for a monetary authority that chooses the money supply. The steady-state inflation rate is above 8 percent for a baseline calibration, but it varies substantially with alternative structural parameter values. If the initial condition...

There are many ways to forecast the future rate of inflation, ranging from sophisticated statistical models involving hundreds of variables to hunches based on past experience. We generate a number of forecasts using a simple statistical model and an even simpler estimating rule, adding in...

Economists have been arguing about the connection between unemployment and infl ation for decades. Critics claim that the connection is unreliable and leads policymakers astray, while others argue that the relationship is useful for forecasting. We examine the more direct connections between...
