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
A strictly concave production function is weakly concave if the rate of decline of the marginal product of capital tends to zero in the limit. This is different from concavity that is not strict, as with a linear function. With a weakly concave function there may be no price-taking profit maximization, or no golden rule steady state. A function of this type throws light on the convergence of infinitely summed discounted utility, and on the Lucas Paradox, the tendency of capital to move from poor to rich countries. Estimation reveals a function with no technical progress, in contrast to standard growth accounting.
