The use of money for tax evasion in the self-employed sector is characterized as an equilibrium outcome in the model economy where the self-employed sector´s output is a natural credit good and all the economic activities are costlessly monitored by the government, except those involving cash in the self-employed sector and all the other cash purchases.

As long as the cash-good sector is sufficiently large relative to the self-employed sector and the after tax nominal interest rate is low relative to the labor tax rate, agents choose cash sales to evade labor tax in the self-employed sector and use the income for expenditure on cash goods next period. Optimal monetary policy implies a positive nominal interest rate since Friedman (1969)´s prescription of a zero nominal interest rate distorts allocation in favor of the self-employed sector which encourages tax evasion. Calibrations of the model economy yield that, when the cash held for tax evasion is 10 percent of the cash-good purchases, optimal policy implies the quarterly nominal interest rate of 7.6%.
