OxTalks is Changing
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
How do taxes affect the trading behavior of private investors? Evidence from individual portfolio data
The removal of an intertemporal tax discontinuity in Germany provides us with a natural experiment to study the causal effect of taxes on individual stock-trading behavior and the disposition effect. Using individual investor transactions data, we find substantial spikes in selling probabilities around the intertemporal tax discontinuity and no such spikes after the abolishment. In all pre-reform years, the disposition effect is reversed (unusual large) to the left (right) of the tax discontinuity. Using bunching methods, non-parametric regressions, and changes in effective tax rates, we find that investors reduce their effective tax rate by 11.3% due to behavioral responses.
