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
We collect time-use data for entrepreneurs and their workers in over 1,000 manufacturing firms in urban Uganda. We document limited labour specialization within the firm for establishments of all sizes and argue that this is likely due to the prevalence of product customization. We then develop a general equilibrium model of task assignment within the firm, estimate it with our data, and find large barriers to labour specialization. This setting is close, in terms of aggregate productivity and firm scale, to an extreme benchmark in which each firm is just a collection of self-employed individuals sharing a production space. Given how firms are organized internally, the benefits from alleviating other frictions that constrain firm growth are muted: most African firms resemble artisanal workshops whose business model is not easily scalable.
