In this paper we argue that measured (RPI) inflation is conceptually mismatched with core inflation: the difference is more than just "measurement error". We propose a technique for measuring core inflation, based on an explicit long-run economic hypothesis. Core inflation is defined as that...

This paper shows how standard methods can be used to formulate and estimate a dynamic index model for random fields—stochastic processes indexed by time and cross section where the time-series and cross-section dimensions are comparable in magnitude. We use these to study dynamic comovements...

Per capita incomes across European regions are not equal and do not stay constant; regional income distributions fluctuate over time. Such a process could have many possible limiting outcomes: complete equality (convergence), stratification, and continually increasing inequality are but three...

The paper uses a model of growth and imperfect capital mobility across multiple economies to characterize the dynamics of (cross-country) income distributions. This allows convenient study of the convergence hypothesis, ad reveals, where appropriate, polarization and clumping within subgroups....

This paper attempts to draw lessons for the New Economy from what economists know about technology dissemination and economic growth. It argues that what is most notable about the New Economy is that it is knowledge-driven, not just in the sense that knowledge now assumes increasing importance...

This paper documents some stylized facts on evolving UK Phillips curves, and shows how these differ from their US versions. We interpret UK Phillips curve dynamics in a positive theory of monetary policy û how policy-maker attitudes on the Phillips curve have evolved since the 1950s û rather...

This paper develops a model of economic growth and activity locating endogenously on a 3-dimensional featureless global geography. The same economic forces influence simulataneously growth, convergence, and spatial agglomeration and clustering. Economic activity is not concentrated on discrete...
