# What is the difference between IS-LM model and Mundell-Fleming model?

The Mundell–Fleming model portrays the short-run relationship between an economy's nominal exchange rate, interest rate, and output (in contrast to the closed-economy IS-LM model, which focuses only on the relationship between the interest rate and output).

What is the difference between IS-LM and Mundell-Fleming model?

The main difference between Mundell-Fleming model and ISLM model relates to the fact that **while ISLM model is effective under a closed-economy, Mundell-Fleming model attempts to analyse an open-economic system**.

## What is the main message of Mundell-Fleming model?

To conclude, the main message of the Mundell-Fleming model is that **the effect of any economic policy (fiscal, monetary or trade) depends on the exchange rate system of the country under consideration**, i.e., whether the country is following a fixed or a floating exchange rate system.

## Why LM curve is vertical in Mundell-Fleming model?

**The intersection of the two curves at the point A determines the equilibrium level of income Y0, which has no relation to e**, shown on the vertical axis of Fig. 12.2(b). This is why the new (open economy) LM curve is vertical.

What is Mundell model also known as?

The Mundell-Fleming model is an open macro application of the standard IS-LM analysis. More precisely, it is an IS-LM analysis with trade and international capital mobility.

## What is the difference between IS and LM model?

What Is the IS-LM Model? 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 (IS) interacts with the loanable funds market (LM) or money market.

## What is the difference between LM and is?

**The IS stands for Investment and Savings.** **The LM stands for Liquidity and Money**. On the vertical axis of the graph, 'r' represents the interest rate on government bonds. The IS-LM model attempts to explain a way to keep the economy in balance through an equilibrium of money supply versus interest rates.

## Is-LM BP Mundell-Fleming?

The IS-LM-BP model (also known as IS-LM-BoP or Mundell-Fleming model) is an extension of the IS-LM model, which was formulated by the economists Robert Mundell and Marcus Fleming, who made almost simultaneously an analysis of open economies in the 60s.

Who developed the concept of IS-LM model *?

John Hicks

A British economist named

John Hicksdeveloped the IS-LM model in 1936, basing it on theories published by another British economist, John Maynard Keynes, only a few months earlier.

## Why LM curve is steeper?

It is correct because the LM curve will be steeper **when the interest sensitivity of money demand is smaller due to the low amount available for speculative activities**. And an increase in income will affect the transactions of other activities rather than speculation.

## IS-LM curve horizontal or vertical?

horizontal

If money demand does not depend on income, then we can write the LM equation as M/P = L(r). For any given level of real balances M/P, there is only one level of the interest rate at which the money market is in equilibrium. Hence, **the LM curve is horizontal**, as shown in Figure 11–18.

What are limitations of Mundell-Fleming model?

Several other shortcomings of the Mundell-Fleming model have also been emphasized. In particular,

the model is completely static and therefore not able to address issues related to the long run, as well as to the transitional dynamics of private wealth and government finance.

## Who gave the Mundell-Fleming model?

Forty years ago, **Marcus Fleming and Robert Mundell** developed independent models of macroeconomic policy in open economies.

## What is the IS-LM model in economics?

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 (IS) interacts with the loanable funds market (LM) or money market**.

### What is an advantage of using the IS-LM model?

The IS-LM model makes both Y and r endogenous. The key advantage of this is that **we can have r determine Ip**. Since the level of planned investment is important in the real world and varies a lot, it's nice to have a model in which that is not just set exogenously.

### What are the assumptions of the IS-LM model?

IS-LM Model Assumptions. **All businesses make similar products, which are utilized for consumption and residential investment**. There is no influence of aggregate supply on the equilibrium level of income, defined by aggregate demand. The only assets in the financial-market are money and bonds.

## What do you mean by IS-LM-BP model?

The IS-LM-BP model

**In the model we distinguish between perfect and imperfect capital mobility, but also between fixed and flexible exchange rates**. For each of these cases, we'll see what happens when both an expansionary monetary and fiscal policy are applied to the economy.

What IS-LM model explain?

- The IS-LM model
**describes how aggregate markets for real goods and financial markets interact to balance the rate of interest and total output in the macroeconomy**. IS-LM stands for “investment-saving” (IS) and “liquidity preference-money supply” (LM).

## What are the limitations of the IS-LM model?

The IS-LM model, however, suffers from two serious limitations: (a) **It is a comparative-static equilibrium model.** **It ignores the time-lags which are important in examining the effects of economic policy changes.** **(b) If has been called the fix-price model**.

What are the 3 stages of LM curve?

- The economic development trajectory can be divided into three sections as per the different slopes of the LM curve:
**the depression section, the middle section and the classical section**( Figure 2).

## Why the IS-LM curve is flat at zero?

The LM curve is flat (slope is close to zero) **when only a small change in the interest rate leads to a large change in money demand** (h is large). Essentially, the public is willing to hold whatever quantity of money is supplied. A change in money supply will have little impact on interest rates and the economy.

## Why is-LM upward sloping?

Why does the LM curve slope upward? The LM curve slopes upward because **a higher gross domestic product (GDP) causes greater demand to hold money for transactions**. This, in turn, raises interest rates, so that money supply and liquidity can stay in equilibrium.

## What is Mundell-Fleming model in Indian economy?

Developed by Robert Mundell and Marcus Fleming in the 1960s, the Mundell- Fleming model studies the implications of capital mobility under a fixed or flexible exchange rate regime in a small open economy. It is an open economy version of the IS-LM model.

## IS-LM in open economy?

**LM Curve is unchanged by open economy considerations**. IS curve: a fall in the domestic interest rate has two effects: – As interest rate fall, investment rises. – As interest rate fall, currency depreciates and net-exports increase.

## What are the limitations of IS-LM model?

The IS-LM model, however, suffers from two serious limitations: (a) **It is a comparative-static equilibrium model.** **It ignores the time-lags which are important in examining the effects of economic policy changes.** **(b) If has been called the fix-price model**.

## IS-LM model example?

Imagine the Fed has decided to increase the discount rate, which reduces the money supply in the economy. The change in money supply directly impacts the LM curve. When there is a decrease in the money supply, there is less money available in the economy, causing the interest rate to increase.
