Tax Evasion and the Demand for Currency in Norway and Sweden. Is There a Hidden Relationship?
研究了挪威和瑞典边际税率对货币需求的影响，发现瑞典的货币需求与税率显著相关，并据此估算隐藏经济规模，但指出该方法不确定性大，不宜依赖。
Variables associated with the level of hidden economic activity are examined in terms of their effects on the demand for currency in Norway and Sweden. Aggregate time series of marginal tax rates are compiled for this purpose. No such effects are evident for Norway, while in the case of Sweden the demand for currency was found to be significantly related to marginal tax rates. These estimates are then used as a basis for deriving an estimate of the size of the hidden economy in Sweden. An analysis of the assumptions underlying this procedure shows that the uncertainty involved in applying the currency approach to measuring the size of the hidden economy is so great as to make it hazardous to rely on such estimates.
