How much of pandemic spending increases was financed through inflation?
Core argument: Across 21 economies—20 non-Euro-zone OECD countries and an aggregate of 17 Euro-zone countries—estimated coefficients of 0.4–0.5 link inflation to scaled government spending, suggesting 40–50% of extra spending was financed through inflation and 50–60% through conventional intertemporal public finance.
We show for a sample of 21 economies—20 non-Euro-zone OECD countries and an aggregated version of 17 Euro-zone countries—that headline and core inflation rates in 2020-2022 responded positively to a theory-motivated government-spending variable. This variable includes cumulated increases in spending-GDP ratios divided by the pre-pandemic level of the debt-to-GDP ratio and by the average duration of the outstanding debt. In contrast, across 17 Euro-zone countries, differences in the government-spending variable do not generate significant differences in inflation rates. We also find in the sample of 21 economies that, while positive and statistically significant, the coefficient that gauges the response of the inflation rate to the scaled measure of government spending is significantly less than one, the value predicted when all of the extra spending is “paid for” through surprise inflation. The point estimates of coefficients of 0.4-0.5 suggest that 40-50% of the extra spending was financed through inflation, whereas the remaining 50-60% was paid for through the more conventional method of intertemporal public finance that involves increases in current or prospective government revenue or cuts in prospective future spending.
