We use two UK panel data sets to investigate skill-upgrading in the United Kingdom and how it has been affected by computerization. Census data reveals that most aggregate skill-upgrading is explained by within-firm rises in skill composition. Such upgrading is significantly related to...

This paper examines whether the sector bias of skill-biased technical change (SBTC) explains changing skill premia within countries in recent decades. First, using a two-factor, two-sector, two-country model we demonstrate that in many cases it is the sector bias of SBTC that determines SBTC’s...

We analyse productivity growth in UK manufacturing 1980-92 using the newly available ARD panel of establishments drawn from the Census of Production. We examine the relative importance of 'internal' restructuring (such as new technology and organizational change) and 'external' restructuring...

The U.K. skill premium fell from the 1950s to the late 1970s and then rose very sharply. This paper examines the contributions to these relative wage movements of international trade and technical change. We first measure trade as changes in product prices and technical change as TFP growth....

The usual analysis of privatization and X-inefficiency uses agency theory to model managerial effort. We model worker effort as determined by a bargain between firms and workers. Workers dislike effort because it lowers utility. Firms prefer high effort because it raises productivity....

Almost all studies of skilled/unskilled employment over the 1980s use data on manuals and non-manuals to measure skill. This paper constructs data on skilled/unskilled employment using occupational data from the UK New Earnings Survey Panel Data set. It merges these data with other product and...

We compare the trade and labour approaches to wage inequality. We first look at the theoretical differences, stressing the different roles ascribed to sector and factor bias, labour supply and the theory of technical change in trade models with endogenous prices. We then briefly review some of...

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...

An extensive literature on the convergence of productivity between countries examines whether productivity is pulled towards the global frontier country, perhaps due to learning and knowledge spillovers. More recently, studies within countries use the wide dispersion of productivity across firms...

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...
