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
The estimation of production functions remains ubiquitous in economics, both at the firm and aggregate level. While some focus on gross output production functions (GO-PF), others use value added production functions (VA-PF). Because value added is constructed as gross output minus intermediary inputs (properly deflated), VA-PFs are but a transformation of the GO-PF. Therefore, regardless of which is the starting point of researchers, one function is implicitly imposing restrictions on the other. Which are these restrictions? Are they reasonable? Does it matter (e.g. for TFP measurement)? I address these questions.
