    Linking productivity to trade in the structural estimation of production within UK manufacturing industries
    (Institute for International Integration Studies (IIIS), 2005-10) ;
    We estimate productivity dynamics within 4-digit manufacturing industries, using FAME data on UK Companies, from 1994 to 2003. We extend the algorithm in Olley and Pakes (1996) to allow for a selection bias driven by the Melitz (2003) effect (high productivity types selecting to exporting) to get more consistent and unbiased estimates of the parameters of the production function. We demonstrate a link between trade orientation and productivity within industries that is driven by selection, not by learning. Hence aggregate productivity is driven by market share reallocations amongst companies rather than from improvements in company level productivity.

    Productivity and trade orientation in UK manufacturing
    (Institute for the Study of Labor, 2007-05) ;
    Within a structural model we explicitly allow for the trade orientation of companies to estimate productivity dynamics within 4-digit UK manufacturing industries. We use the FAME data on UK companies over the period 1994-2003. Following Ackerberg et al. (2005) we adjust the algorithm in Olley and Pakes (1996) by augmenting investment and exit decisions to allow for exogenous demand shocks by trade orientation, assuming that labour and capital are state variables, and productivity follows a first-order Markov process. We extend the framework further by allowing exporting to be an additional control variable that is driven by lagged productivity as in Melitz (2003), leading productivity to follow a second-order Markov process. We find that over the period of introduction of the Euro improvements in aggregate productivity were driven by exporters - mainly by market share reallocations away from inefficient and towards efficient export companies. Aggregate productivity also benefited from improvements in productivity of non-exporters but was driven by improvements within companies rather than by market share reallocations. In a period of sustained real exchange rate appreciation both export cleansing and competitive pressure on non-exporters seem to have contributed to improvements of productivity in the UK manufacturing.

    Is there a rural-urban divide? Location and productivity of UK manufacturing
    (University College Dublin. Geary Institute, 2009-08) ;
    We compute the productivity gaps in manufacturing industries by urban, rural less sparse and rural sparse locations in the UK. This is done by using firm-specific total factor productivities, which are estimated by a semi-parametric algorithm within 4-digit manufacturing industries using FAME data over the period 1994-2001, by each location. We analyse the productivity differentials across locations by decomposing them into firm differences within the same industry and by differences that are explained by industry composition effects. Our analysis indicates that at the end of twentieth century a rural-urban divide in manufacturing productivity still remains but there is a tendency of convergence between rural and urban location categories. Even though industry productivity is different by location, industry composition effects are positively correlated with industry productivity by location suggesting that locations with high productivity are also characterised by industrial structures with higher productivity.
