• Putting all flows together shows us that
they are indeed circular.
• Therefore the dollars that flow around
counterclockwise (in this example) are
equal to…
• The goods, services, and factors of
production that flow around clockwise (in
this example).

Does the Circular Flow Leak?
• Classical economists were guided by
Say’s Law.
• In a simple economy Say’s Law states that
by producing goods and services, firms
create a total demand for goods and
services equal to what they have
produced.
• Or more simply, supply creates its own
demand. So yes there may be leaks!
15
But it also gets “pumped up”!
• Households don’t spend all of their income. Rather,
some of their income goes to savings (leakage) or to pay
taxes (leakage).
• Households are not the only spenders in the economy.
Rather, firms also spend money on capital goods
(injection) and the government also spends money on
final goods and services (injection).
• In addition to markets for goods and markets for
resources, there is also a loanable funds market where
household saving is made available to firms and the
government.
16
• Total spending in the circular flow will
equal total output in the circular flow if
and only if leakages in the economy are
equal to total injections.
17
Total Spending
=
Total Output
Or… what goes around comes around!
18
Government has a role in the
economy…
• However, the government’s role in the
economy is dependent on the taxes it
charges (and firms and households pay).
• And that role includes providing goods and
services to those same firms and
housholds!
