🔹 Post-pandemic inflation was largely an endogenous response of commodity prices to macro developments, not driven by supply shocks.
🔹 Commodity costs are a crucial—but often ignored—link between macro conditions and inflation.

Because demand shocks did matter — but their inflationary impact didn’t flow through the usual “Phillips Curve” channels like the output gap or labor market tightness. It was transmitted elsewhere.
🔹 VAR-based studies (e.g. @DomenicoGiannon & @gprimice) attribute the inflation surge mainly to demand shocks
🔹 Phillips Curve studies (e.g. Bernanke & @ojblanchard1) find little evidence for that view
➡️When I account for endogeneity by instrumenting commodity prices with exogenous shocks from the SVAR, the Phillips Curve steepens markedly.
This omission can bias the estimates. 👇
This channel is typically ignored in standard Phillips Curve estimations...
➡️ global business cycle
➡️ fiscal policy
➡️ (especially) monetary policy
As a result, exogenous shocks—like the Russian invasion of Ukraine—had also only a modest effect on overall inflation. 👇
Wat ik niet begrijp: "social benefits received" (zou health care en education zijn) voor top-1% inkomens bedragen €100.000 per jaar... Waarom is dat zoveel hoger i.v.m. top-10% inkomens?
