Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
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.
