ALMOST EVERY COUNTRY has a minimum wage.
e details var y: some countries, such as France,
fix a universal mi nimum across the economy,
while others, such as New Ze aland and South
Africa, di fferentiate between sectors and t ypes
of workers. Typically, the minimum wage is set
by the government and revised periodically in
consultation with business and labor organiza-
tions (see chart).
Minimum wages have be en justified on moral,
social, and economic grounds. But the overa rching

market for labor. ey argue that t here are other,
better-targeted, and less distortionary ways to
provide socia l assistance.

First, employers may not comply with the min-
imum wage law. If no one actually receives t he
minimum, or if the law is mostly on paper, it is
irrelevant. For example, in countries with large
shadow economies, employers often give work-
ers under-the-table wage supplements, sometimes
known as “envelope payments,” to evade taxes or
the cost of providing benefits. In th is situation, the
employer could react to an increase in the mini-
mum wage by reducing envelope payments, leaving
overall compensation uncha nged. Employers might
also underreport the number of hours employees
worked, also leaving tota l pay unchanged. Or the
employer might not report employme nt at all,
evading the minimum wage law entirely.
Second, even when minimum wage reg ulations
are fully respec ted, additional earn ings may face
