This paper considers the relationship between taxes and the size of the New Zealand underground economy. Previous studies indicate that a positive relationship exists in this and certain other countries. This paper addresses the question: 'Is the response of the underground economy to an increase in taxes the same as its response to a decrease in taxes?' We find that although the effect on the underground economy of an upward movement in the effective tax rate is numerically greater than that of a downward tax movement, this difference is not statistically significant. 相似文献

Using new time-series data for the size of the Canadian underground economy, the relationship between unreported and measured GDP in that country is examined. Granger causality tests are conducted, with a proper allowance for the non-stationarity of the data. It is found that there is clear evidence of such causality from measured GDP to ‘hidden’ output, but only very mild evidence of Granger causality in the reverse direction. This result supports similar evidence for New Zealand reported by the first author, and has several interesting policy implications. 相似文献
