Algebraic quantity equations before Fisher and Pigou
Readers of this Review are doubtlessly familiar with the famous equation of exchange, MV=PQ, frequently employed to analyze the price level effects of monetary shocks. One might think the algebraic formulation of the equation is an outgrowth of the 20th century tendency toward mathematical modeling and statistical testing. Indeed, textbooks typically associate the transaction velocity version of the equation with Irving Fisher and the alternative Cambridge cash balance version with A. C. Pigou, two early 20th century proponents of the application of mathematics to economic analysis. The ...

Measuring core inflation: notes from a 2007 Dallas Fed conference
In May 2007, the Federal Reserve Bank of Dallas hosted a conference, organized with the Federal Reserve Bank of Cleveland, titled "Price Measurement for Monetary Policy." The conference broadly focused on two issues - the measurement of core inflation and the measurement of inflation expectations. This paper summarizes the conference papers on core inflation.

Local price variation and labor supply behavior
In standard economic theory, labor supply decisions depend on the complete set of prices: the wage and the prices of relevant consumption goods. Nonetheless, most of theoretical and empirical work ignores prices other than wages when studying labor supply. The question we address in this paper is whether the common practice of ignoring local price variation in labor supply studies is as innocuous as has generally been assumed. We describe a simple model to demonstrate that the effects of wage and non-labor income on labor supply will typically differ by location. We show, in particular, the ...

Price setting, price dispersion, and the value of money - or - The law of two prices
We study models that combine search, monetary exchange, price posting by sellers, and buyers with preferences that differ across random meetings - say, because sellers in different meetings produce different varieties of the same good. We show how these features interact to influence the price level (i.e., the value of money) and price dispersion. First, price-posting equilibria exist with valued fiat currency, which is not true in the standard model. Second, although both are possible, price dispersion is more common than a single price. Third, perhaps surprisingly, we prove generically ...

Optimal interest rate rules and inflation stabilization versus price-level stabilization
This paper compares the properties of interest rate rules such as simple Taylor rules and rules that respond to price-level fluctuations?called Wicksellian rules?in a basic forward-looking model. By introducing appropriate history dependence in policy, Wicksellian rules perform better than optimal Taylor rules in terms of welfare and robustness to alternative shock processes, and they are less prone to equilibrium indeterminacy. A simple Wicksellian rule augmented with a high degree of interest rate inertia resembles a robustly optimal rule?that is, a monetary policy rule that implements the ...

Inflation, slack, and Fed credibility
It is generally agreed that slack has some impact on inflation. There is much less agreement on what form the relationship takes and whether it is stable enough to reliably help predict inflation. This analysis focuses on the Great Moderation period. We find that slack (as measured by the unemployment rate) and changes in slack are negatively correlated with changes in inflation and also deviations of inflation from long-forward inflation expectations.> ; These relationships could have been exploited to produce forecasts of trimmed mean PCE inflation more accurate than rule-of-thumb ...
