13. 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).

15. 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!

16. 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.

17. 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.

18. Total Spending = Total Output Or… what goes around comes around!

19. 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!
