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:
Fifty percent of startups fail within five years, and those that survive grow at vastly different speeds. Using Census microdata, we estimate that the lion’s share of these differences is determined by ex-ante heterogeneity rather than persistent ex-post shocks. Embedding such heterogeneity in a firm dynamics model shows that ex-ante differences are key determinants of the firm size distribution, up-or-out dynamics, and associated aggregate gains. Gazelles, rare high-growth startups, are essential for these outcomes. Analyzing changes in the distribution of ex-ante heterogeneity over time reveals that the birth rate and growth potential of gazelles has declined, creating substantial aggregate losses.
