This paper examines the application of count data models to firm level panel data on technological innovations. The model the authors propose exhibits dynamic feedback and unobserved heterogeneity. We develop a fixed effects estimator that generalizes the standard Poisson and negative binomial...

This article investigates the evolution of quality-adjusted prices for servers motivated by two facts. First, the recent productivity acceleration in the US is closely linked to the spread of IT of which networked computing is a large component. Second, the growth of network computing itself has...

With increasing globalisation of knowledge, there are increased opportunities to 'learn' from the experience of policy interventions elsewhere. This paper presents evidence on the extent of international convergence in public policy, with particular focus on labour, welfare, savings and...

Analysing the new IFS-Leverhulme database on over 200 major British firms since 1968 we show that patents have an economically and statistically significant impact on firm-level productivity and market value. While patenting feeds into market values immediately it appears to have a slower effect...

We investigate the relationship between export market shares and relative unit labour costs using a long panel of 12 manufacturing industries across 14 OECD countries. We ask how sensitive are export market shares to changes in relative costs and what determines this sensitivity? Both costs and...

<abstractinfo format="display"> We analyse the impact of product market competition on unemployment, and how this depends on labour market institutions. Theoretically, both firms with market power and unions with bargaining power are constrained in their behaviour by the elasticity of demand in the product market. We use...</abstractinfo>

Recently the data underlying the Annual Census of Production has been made available to academic economists in the United Kingdom. The data provide information on production activity in the United Kingdom at the plant level. This paper provides some preliminary description of the data and...

This paper investigates the relationship between investments in human capital and R&D in a model of endogenous growth. Both forms of investment exhibit pecuniary externalities and are, as a result, strategic complements. Multiple equilibria may occur for intermediate parameter values and the...
