OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, 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.
