This article analyzes the effect of a one-time tax amnesty intended to
induce private citizens to voluntarily declare black assets accumulat
ed from past tax evasion. in a dynamic setting, we find that such an a
mnesty tends to enhance voluntary taxpayer compliance and reduce the s
ize of the underground economy. However, it also generally lends to re
duce aggregate net revenues collected by the government in the long nm
, provided black assets command a higher pretax rate or return than wh
ite assets. This is due to a post-amnesty reduction in involuntary rev
enue collections that outweighs direct amnesty receipts and the increa
se in voluntary compliance. The desirability of such amnesties thus de
pends on the importance of unearthing black assets per se, relative to
increasing revenue collections.
