This paper investigates whether permanent monetary tightenings increase inflation in the short run. It estimates, using U.S. data, an empirical and a New-Keynesian model driven by transitory and permanent monetary and real shocks. Temporary increases in the nominal interest-rate lead, in...

I investigate the effects of an increase in the nominal interest rate on inflation and output in the United States and Japan during the postwar period. I postulate a structural autoregressive model that allows for transitory and permanent nominal and real shocks. I find that nominal...

We study the long-run relation between money, measured by inflation or interest rates, and unemployment. We first discuss data, documenting a strong positive relation between the variables at low frequencies. We then develop a framework where both money and unemployment are modeled using...

Increasing the inflation target in a textbook New Keynesian (NK) model may require increasing, rather than decreasing, the nominal interest rate in the short run. We refer to this positive short run co-movement between the nominal interest rate and inflation conditional on a nominal shock as...

We consider the puzzling behavior of interest rates and inflation in the United States and the United Kingdom between 1879 and 1913. A deflationary regime prior to 1896 was followed by an inflationary one from 1896 until the beginning of World War I; the average inflation rate was 3.8 percentage...

This note tests the hypothesis that nominal interest differentials between similar assets denominated in different currencies can be explained entirely by the expected change in the exchange rate over the holding period. This proposition, often called the "Fisher open" hypothesis or the...

The basic puzzle about the so-called Fisher effect, in which movements in short-term interest rates primarily reflect fluctuations in expected inflation, is why a strong Fisher effect occurs only for certain periods but not for others. This paper resolves this puzzle by reexamining the...

For the period 1860 to 1939, the simple correlation of the U.S. commercial paper rate with the contemporaneous inflation rate is -.17. The corresponding correlation for the period 1950 to 1979 is .71. Inflation evolved from essentially a white noise process in the pre-World War I years to a...

There is a long-standing debate as to whether the Fisher effect operated during the classical gold standard period. We break new ground on this question by developing a market-based measure of general inflation expectations during the gold standard. Since the gold-silver price ratio was widely...

This paper critically re-examines theory and evidence on the relation- ship between interest rates and inflation. It concludes that there is no evidence that interest rates respond to inflation in the way that classical or Keynesian theories suggest, For the period 1860-1940, it does not appear...
