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 construct firm-level data set with matched productivity and qualification data by linking the Annual Business Inquiry and Employer Skills Survey for England. We first examine the effect of workplace skills and other characteristics such as part-time status and gender on both productivity and...

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...

The usual analysis of privatization and X-inefficiency uses agency theory to model managerial effort. The authors 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....

An enormous number of empirical papers have estimated technical efficiency, the distance of firms inside a frontier, following the model of Farrell (1957). We propose a theory that explains the distance these empirical papers seek to measure. The theory is based on the idea that workers can...

We use a new sample of UK female identical twins to estimate private economic returns to education. We report findings in three areas. First, we use identical twins, to control for family effects and genetic ability bias, and the education reported by the other twin to control for schooling...

Investigates changes in skilled and unskilled employment over the 1980s using UK data skills from the Labour Force Survey and the New Earnings Survey Panel Data set, matched with industrial data from the Census of Production. The major findings are: that there was a rise in on‐manual wage and...
