This note responds to the recent critique by Goodridge, Haskel and Wallis (GHW) of our 2012 study of Britain's productivity puzzle. We show that a correct reworking of the latest official data on changes in labour composition overturns GHW's main criticism. We also question the strength of the...

There is no consensus about the causes of the reduction in business cycle volatility seen in many major economies over the last decade. Using stylised models of the economies of the US, Euro area, UK and Japan, we argue that economic stability has been fostered by improved monetary policy and by...

This paper fully characterizes the optimal control of a recurrent infectious disease through the use of (non-vaccine) prevention and treatment. The dynamic system may admit multiple steady states and the optimal policy may be path dependent. We find that an optimal path cannot end at a point...

Since the seminal work of Blanchard and Katz, it has been widely believed that interstate migration causes state-level employment rates in the United States to revert rapidly to normal following a regional employment shock. This paper identifies two sources of bias in conventional estimates of...

We model the coevolution of behavioral strategies and social learning rules in the context of a cooperative dilemma, a situation in which individuals must decide whether or not to subordinate their own interests to those of the group. There are two learning rules in our model, conformism and...

In this paper we survey the theories of gratuitous cooperation, i.e., in favour of non-relatives and without repeated interaction. We also describe our work on the area, whose objective is to integrate the various theories of gratuitous cooperation into a self-contained framework. Our...

Using simple convergence equations, this paper projects that by mid-century per capita incomes in China and India will on average be about half the US level. In terms of total production, both countries should overtake the USA by 2050. Such developments will affect the advanced economies through...

This paper is concerned with the geography of structural change in Great Britain since 1971. It divides the country into two broad areas - the 'North' comprising Northern England, the West Midlands, Wales and Scotland, and the 'South' comprising the rest of mainland Britain.

This paper defines de-industrialisation as a secular decline in the share of manufacturing in national employment. De-industrialisation, in this sense, has been a widespread feature of economic growth in advanced economies in recent decades. The paper considers briefly what explains this...
