In the model, currency suppression increases transactions costs and raises effective tax rates, but shifts resources out of costly underground markets and relaxes the government budget. When coupled with a reduction in distortionary taxes on consumption or factor inputs to ensure budget neutrality, cash suppression policies increase welfare in our baseline representative agent model. In a model with individual heterogeneity in cash use, suppression increases welfare for all, but by less for cash-intensive users. 收起
