Macroeconometric Models
Lawrence Klein developed the first U.S. macroeconomic model in the early 1950s. The model was an extended IS relation, with 16 equations.
Paul Samuelson wrote the first modern economics textbook: Economics

The Phillips Curve
The Phillips curve had become part of the Neoclassical synthesis, but Milton Friedman and Edmund Phelps argued that the apparent trade-off between unemployment and inflation would quickly vanish if policy makers actually tried to exploit it. By the mid 1970s, the consensus was that there was no long-run trade off between inflation and unemployment.
Solow
It was followed by an explosion of work on the roles saving and technological progress play in determining growth.

27-2 The Neoclassical Synthesis
Chapter 7: Epilogue: The Story of Macroeconomics
Friedman challenged the view that fiscal policy could affect output faster and more reliably than monetary policy.
In a 1963 book, A Monetary History of the United States, 1867-1960, Friedman and Anna Schwartz reviewed the history of monetary policy and concluded that monetary policy was not only very powerful, but that movements in money also explained most of the fluctuations in output.
In the process of deriving effective demand, Keynes introduced many of the building blocks of modern macroeconomics:
▪ The relation of consumption to income, and the multiplier.
Modigliani
In the 1950s, Franco Modigliani and Milton Friedman independently developed the theory of consumption, and insisted on the importance of expectations.

The IS-LM Model
The most influential formalization of Keynes’s ideas was the IS-LM model, developed by John Hicks and Alvin Hansen in the 1930s and early 1940s. Discussions became organized around the slopes of the IS and LM curves.
Keynes
The Great Depression was an intellectual failure for the economists working on business cycle theory—as macroeconomics was then called.
Keynes emphasized effective demand, now called aggregate demand.

27-1
Keynes and the Great Depression
The history of modern macroeconomics starts in 1936, with the publication of Keynes’s General Theory of Employment, Interest, and Money.
▪ Liquidity preference (the term given to the demand for money)
▪ The importance of expectations in affecting consumption and investment; and the idea that animal spirits are a major factor behind
James Tobin developed the theory of investment based on the relation between the present value of profits and investment. Dale Jorgenson further developed and tested the theory.
In the 1960s, debates between Keynesians and monetarists dominated the economic headlines. The debates centered around three issues: (1) the effectiveness of monetary policy versus fiscal policy, (2) the Phillips curve, and (3) the role of policy.
The neoclassical synthesis was to remain the dominant view for another 20 years. The period from the early 1940s to the early 1970s was called the golden age of macroeconomics.
Friedman
Milton Friedman was the intellectual leader of the monetarists, and the father of the theory of consumption.
He believed that the understanding of the economy remained very limited, and questioned the motives and ability of governments to improve macroeconomic outcomes.
