There has much recent academic and policy interest in the issue of spatial clustering of economic activity, with most attention paid to the geographic concentration of high-tech industries. This paper describes patterns of geographic and industrial concentration in UK production industries at...

We analyse a puzzle in the UK corporation tax: by both historic and international standards, corporation tax revenues have been high while the statutory rate has been reduced. We consider explanations based on changes in the tax law and in economic factors. Changes in the tax law, such as...
