This paper examines the history of econometrics through a particular case study - modelling the tradeoff between inflation and unemployment. It focuses on the questions of what econometric tools modellers would choose to model the tradeoff, how their choices helped shape the ways that they...

This paper offers a reappraisal of the inflation-unemployment tradeoff, based on ``frictional growth,'' describing the interplay between nominal frictions and money growth. When the money supply grows in the presence of price inertia (due to staggered wage contracts with time discounting), the...

This paper analyses the relation between US inflation and unemployment from the perspective of "frictional growth," a phenomenon arising from the interplay between growth and frictions. In particular, we examine the interaction between money growth (on the one hand) and various real and nominal...

We propose a way to test the New Keynesian Phillips Curve (NKPC) without estimating the structural parameters governing the curve, i.e. price stickiness and firms' backwardness. Using this strategy we can test the NKPC avoiding the identification problems related to the GMM approach. We find...

We review the main New Keynesian inflation equations that have arisen as a result of aggregation from individual firms' price rigidities. We find that, on the whole, they cannot account for inflation persistence, a key feature of the empirical dynamics of inflation, and with important policy...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call ``frictional growth'', i.e. the interaction between money growth and...
