OxTalks is Changing
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
Stand Out from the Millions: Market Congestion and Information Friction on Global E-Commerce Platforms
We investigate how market congestion and information friction affect firm dy-namics and market efficiency in global e-commerce. Observational data and self-collected quality measures from AliExpress suggest significant demand frictions andpotential misallocation in the online market. A randomized experiment that offersnew exporters exogenous demand and information shocks demonstrates the limitedability of existing platform mechanisms to help small sellers overcome the demandfrictions. We show theoretically and quantitatively that having a large number ofmarket participants undermines the functioning of existing online mechanisms andhinders the discovery of high-quality sellers. Policy counterfactuals highlight thatblanket-wide onboarding initiatives can aggravate market congestion, slow down theresolution of the information problem, and result in market misallocation.
