Welfare Consequences of Gradual Disinflation in Emerging Economies
研究了新兴经济体渐进式降低通胀的福利影响，发现季度通胀率下降12%带来总福利增加0.40%，但穷人获益较少，因为其现金持有少、通胀税负担轻。
Abstract Emerging economies display considerable inequality in monetary asset holdings, rendering the recent disinflation nontrivial. Using a small open‐economy model with uninsurable idiosyncratic risk, this paper shows that a gradual decline of 12% in the quarterly inflation rate leads to an aggregate welfare gain of 0.40% in consumption equivalent terms. The poor gain less than the economy on aggregate, despite holding a more inflation‐prone financial portfolio. This is because unequal cash holdings make inflation tax payments of the poor much smaller than those of the rich. When inflation tax revenues finance redistributive transfers that provide insurance, cross‐sectional gains become even more dispersed.
