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
We exploit information in patent applications to construct an instrumental variable for the identification of technology news shocks that relaxes all the identifying assumptions traditionally used in the literature. Our sole requirement is that no structural disturbances affect the US economy via the instrument except for contemporaneous technology news. The instrument recovers news shocks that have no effect on aggregate productivity in the short-run, but are a significant driver of its trend component. News shocks prompt a sustained business cycle expansion in anticipation of the future increase in TFP and, while not a main driver of business cycles, are responsible for a non-trivial share of economic fluctuations. The stock market prices-in news shocks on impact but consumer expectations, dragged down by labor market outcomes, take sensibly longer to adjust, consistent with the predictions of models of information frictions.
