The IS-LM model, which stands for “investment-saving” (IS) and “liquidity preference-money supply” (LM), is a Keynesian macroeconomic model that shows how the market for economic goods interacts with the loanable funds market, or money market. It is represented as a graph in which the IS and LM curves intersect to show the short-run equilibrium bet...
British economist John Hicks first introduced the IS-LM model in 1937, not long after fellow British economist John Maynard Keynes published The General Theory of Employment, Interest, and Money in 1936. Hicks’ model served as a formalized graphical representation of Keynes’ theories, though it is used mainly as a heuristicdevice today. The three c...
The IS-LM graph consists of two curves: IS and LM. GDP is placed on the horizontal axis, increasing to the right. The interest rate makes up the vertical axis.
Many economists, including many Keynesians, object to the IS-LM model for its simplistic and unrealistic assumptions about the macroeconomy. It cannot account for simultaneous high unemployment and inflation in the economy. It is also undercut by the change by central banks to using an interest-rate rule rather than targeting the money supply. Even...
The IS-LM model is a tool for looking at how the market for economic goods intersects with the loanable funds market. It depicts the short-term equilibrium point between interest rates and output, with its three variables being liquidity, investment, and consumption. Because it is a highly simplistic device, it is only useful when snap decisions mu...
LM represents the price (in interest rate) that entrepreneurs are willing to pay in order to acquire capital to invest in a project. As the economy improves, there is more of a reason to engage in new entrepreneurial activities, so ceteris paribus they would be willing to pay more then.

Jun 10, 2024 · The basis of the IS-LM model is an analysis of the money market and an analysis of the goods market, which together determine the equilibrium levels of interest rates and output in the economy, given prices.
The Model of the Goods (and Services) Market (Model 1) We proceed in steps, starting from the simplest model and then making more complicated (realistic) by relaxing assumptions. Model 1: The Goods market. market: the market for goods and services. variable to determine: the level of production, or output.
The IS–LM model, or Hicks–Hansen model, is a two-dimensional macroeconomic model which is used as a pedagogical tool in macroeconomic teaching. The IS–LM model shows the relationship between interest rates and output in the short run in a closed economy.
