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
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.
