This paper contains an analysis of the effect of inflation on aggregate tax evasion in the United States over the period 1947-81. It is found that tax evasion in both absolute and relative terms is positively related to the inflation rate. Further, the results indicate that aggregate evasion has risen in both absolute and relative terms with increases in the marginal tax rate, but has fallen with increases in the detection probability, the penalty rate, and the wage share of income. Finally, evasion has risen in absolute terms but has fallen in relative terms when real true income has risen.

Much research has shown that mortgage rates exert a negative influence on housing prices. This study analyses the long- and short-run relationships between housing prices and mortgage rates using advanced nonstructural estimation methods. As expected, a bivariate specification and a four-variable housing demand specification both show that these variables have a long-run relationship, and that there is a rather inelastic response of housing prices to changes in mortgage rates. However, contrary to previous research, the results from Granger non-causality tests, impulse response functions and variance decompositions reveal that there is virtually no short-run influence from mortgage rates to housing prices.

SUMMARY In this paper, it is argued that average tax rates exert an influence on income tax evasion separate from, and opposite to that of marginal tax rates. Failure to account for this effect in empirical evasion models biases the parameter estimate of the marginal rate in a predictable manner. Evidence from an aggregate empirical model of evasion in the US indicates that the marginal tax rate is positively related to evasion, whereas the average tax rate is negatively related. Further, exclusion of the average rate from the model does in fact bias the parameter estimate of the marginal tax rate.
