Introduction
• A Research-driven Approach to
Macroeconomic Teaching
–Revolutions and Counter-revolution in
Macroeconomics
–Moving beyond the old IS-LM model
–Transcending the current New
Consensus Macroeconomics (NCM)
model

Endogenous Money and the Conduct
of Macroeconomic Policy
• Endogenous Money versus Exogenous
Money
• The Main Tenets of Endogenous Money
Theory:
– Loans create deposits
– Deposits make monetary reserves

Deriving the Aggregate Demand (AD)
Curve
–A simple set of equations
–No Pigou effect (M is endogenous)!
–The shape of the AD curve is a policy
construct

Deriving the Aggregate Demand (AD)
Curve
• Basic Glossary
ND = Components of Aggregate Demand that are
not debt-financed by loans from banks
D = Planned or desired debt-financed (by loans from
banks) spending
c = Proportion of creditworthy households and
business loans
rL = bank loans rate (set as a mark-up m over the
central bank’s short-run interest rate i)

Completing the Endogenous Money Model
• Basic Glossary
P = firms set prices as a fixed mark-up n over the
average cost of labour Wa
W= nominal wage (fixed for length of contract)
a = labour/output ratio, namely N/Y (like the capital
output ratio K/Y this is given in short-run)
S N = Labour supply schedule
L = entire labour force
