This paper evaluates the temporary VAT reduction introduced by the German government over the third and fourth quarter of 2020 as most controversial part of the COVID-19 stimulus package. Critics argue that VAT reductions are ineffective because of limited pass-through of temporary measures to...

This paper revives the question of whether a temporary VAT change is an adequate instrument for crisis stabilization. In empirical assessments, we find that durable goods consumption fluctuates strongly over the business cycle and that VAT rate changes affect durable goods in particular....
