The model was an attempt to integrate the phenomenon of secular stagnation in the IS-LM model. Whereas in the IS-LM model, high unemployment would be a temporary phenomenon caused by sticky wages and prices, in the IS-LM-NAC model high unemployment may be a permanent situation caused by pessimistic beliefs - a particular instance of what Keynes ...

This is the familiar IS-LM model. Like the classical approach, the IS-LM model contains an equilibrium condition that equates saving and investment. The loanable funds doctrine, by contrast, does not equate saving and investment, both understood in an ex ante sense, but integrates bank credit creation into this equilibrium condition.
IS–LM model, displaying interest rates (i) on the y-axis and national income or production (Y) on the x-axis. Hansen's best known contribution to economics was his and John Hicks's development of the IS–LM model, also known as the "Hicks–Hansen synthesis." The framework claims to graphically represent the investment-savings (IS) curve and ...
The IS-LM model, created by Hicks (1937), is a tool for analysis that aims to condense a complex text like the GT into a straightforward model of three markets, one of which is residual. The LM curve depicts the equilibrium in the money market and uses output as an exogenous variable, while the IS curve portrays equilibrium in the goods market ...
This model formalised an interpretation of the theory of John Maynard Keynes (see Keynesian economics), and describes the economy as a balance between three commodities: money, consumption and investment. Hicks himself wavered in his acceptance of his IS–LM formulation; in a paper published in 1980 he dismissed it as a ‘classroom gadget’. [9]
The Mundell–Fleming model under a fixed exchange rate regime also has completely different implications from those of the closed economy IS-LM model. In the closed economy model, if the central bank expands the money supply the LM curve shifts out, and as a result income goes up and the domestic interest rate goes down.
This model is further advanced in higher levels of undergraduate studies. David Romer proposed in 2000 that the LM curve be replaced in the IS–LM model. [1] Instead, Romer suggested that although the Federal Reserve uses open market operations to impact the federal funds rate, they are not targeting money supply, but rather the interest rate.
