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
This paper measures the causal effect of deficits on inflation using a “high frequency narrative approach”. We identify an event that released news about the 2021 deficits in the United States—the Georgia Senate election runoff. We calculate the size of the shock using new narrative data from investment banks. We then study the high frequency response of inflation forecasts from asset prices, in order to separate deficits from other factors affecting inflation. We estimate an “inflation multiplier” of 0.18% price level growth over two years, for a 1% deficit-to-GDP shock. Our estimate implies that the 2021 deficits caused around 30% of the 2021-22 inflation—meaning deficits were important but not the only cause. A standard heterogeneous agent New Keynesian model quantitatively matches the size and dynamics inflation multiplier
