On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Abstract
As many other advanced economies, the labour market in the United Kingdom have polarised in the recent decades, with jobs in middle income or skill occupations disappearing. This paper analyses the importance of labour demand and supply factors in the observed job polarisation in the UK, between 1992 and 2008. First, it provides an estimates of the skill distributions at the task level, using the British Household Panel Survey. Importantly, such estimations includes the ability of workers in tasks in which they are observes and their counterfactual ability in occupations in which they are not observed. This is a novel contribution to the literature. Using these estimated distributions (positive-skewed), a simple model is used to identify the nature of task-biased technical change affecting the UK over the period. Using counterfactual analysis it is shown that the change in skills played little role in observed polarisation patterns; technological change is to blame for such developments. In other words, in the United Kingdom, the recent race between technology and education was won by the former.
