Minimum Wage and Tax Evasion: Theory and Evidence

The paper investigates the role of the minimum wage in a competitive economy in which there is underreporting of earnings by employed labour. The minimum wage induces higher compliance by some low- productivity workers and transforms a nominally neutral fiscal system into a regressive one. A spike in the wage distribution at the mini- mum wage level appears and a positive correlation between the size of the spike and the size of the informal economy is predicted and documented using cross-country data for Europe. A further result is that employees whose officially declared earnings appear to be boosted by a minimum wage hike actually experience a decline in their true income. This prediction finds support in an empirical test using the massive increase in the minimum wage that took place in Hungary in 2001 as a quasi-natural experiment.http://deepblue.lib.umich.edu/bitstream/2027.42/57245/1/wp865 .pd
