The paper compares the trade and labor approaches to wage inequality. It first looks at the theoretical differences, stressing the different roles ascribed to sector and factor bias, labor supply and the theory of technical change in trade models with endogenous prices. It then briefly reviews...

Many productivity studies, if they cover the service sector, commonly enter a caveat that the data are uncertain or just look at manufacturing. This paper attempts to clarify what UK market-service-sector data are available, whether they should be treated as inaccurate, and what conceptual...

Pressure on public finances has increased scrutiny of public support for innovation. We examine two particular issues. First, there have been many recent calls for the (relatively new) UK R&D subsidy to be extended to other “research” activities, such as software. Second, argument still...

We use UK micro data to explore whether planning regulation reduced UK retailing productivity growth between 1997 and 2003. We document a shift to smaller shops, particularly within supermarket chains, following a regulatory change in 1996 which increased the costs of opening large stores. This...

Pressure on public finances has increased scrutiny of public support for innovation. We examine two particular issues. First, there have been many recent calls for the (relatively new) UK R&D subsidy to be extended to other research activities, such as software. Second, argument still rages...

We (a) propose an implementable innovation index, (b) relate it to existing innovation definitions and (c) show whole-economy and industry-specific results for the UK market sector, 2000-2005. Our innovation measure starts by observing that we could get more GDP without innovation by simply...

We examine the relationships between productivity growth, IT investment and organisational change (∆O) using UK firm data. Consistent with the small number of other micro studies we find (a) IT appears to have high returns in a growth accounting sense when ∆O is omitted; when ∆O is included...
