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
In this paper, I investigate the perceived valuation of the implicit contribution incentives provided by public pension systems. I take advantage of the unique setting offered by the public pension system in Spain, where self-employed workers can voluntarily determine the level of their Social Security contributions. Using quasi-experimental variations arising from three pension reforms, I find that (i) only 10.35% of self-employed individuals respond to the substantial contribution incentives offered by the Spanish public pension system; (ii) responses are more pronounced when contribution incentives are more salient; (iii) a significant proportion of self-employed individuals overcontribute in cases where contributions yield no pension return. My results suggest that taxpayers face challenges in valuing the implicit contribution incentives of earnings-related public pension systems. I conclude that more salient Social Security contribution incentives could potentially lead to substantial efficiency gains.
