Expanded Multiplier Model (Open Economy with Government, Trade, and Endogenous Investment)
This advanced macroeconomic model expands upon the simplified multiplier framework by incorporating the government sector, international trade (the rest of the world), and a more detailed model of investment. A fundamental assumption of this model is that firms are willing to supply any amount of goods demanded, meaning that output adjusts to meet aggregate demand. This expansion provides a more realistic analysis of how equilibrium output is determined, with the size of the multiplier depending on key variables like the marginal propensity to consume, the tax rate, and the marginal propensity to import.

Expanded Multiplier Model (Open Economy with Government, Trade, and Endogenous Investment)
In an economic model consisting only of households and firms, where there is no government activity or international trade, the marginal propensity to consume is 0.8. If firms in this economy decide to increase their planned investment by $50 billion, what will be the total resulting increase in the economy's aggregate output?
In a simplified economic model with no government or international trade, a decision by households to save a larger portion of any additional income they receive will lead to a larger overall impact on total output from any given change in investment spending.
An economy, which consists only of households and firms and does not engage in international trade, experiences a $100 million increase in planned business investment. Arrange the following events in the correct chronological order to illustrate the resulting economic process.

Assumptions of the Simplified Multiplier Model
In an economic model that includes only households and firms (with no government or international trade), an initial change in spending sets off a chain reaction. Match each term related to this process with its correct description.
In an economic model that only includes households and firms, with no international trade, a $20 billion increase in planned investment spending leads to a total increase in the economy's output of $100 billion. Based on this outcome, the marginal propensity to consume must be ___.
Evaluating the Simplified Economic Model
In a closed economy with no government sector, an initial increase in planned investment of $200 million occurs. If the marginal propensity to consume is 0.6, what is the increase in consumption spending that results from the second round of the multiplier effect?

Components of Aggregate Demand in an Open Economy with Government
Consider two economies, A and B, that are identical in every way except for their tax policies and international trade patterns. Both economies have a marginal propensity to consume of 0.8. Economy A has a tax rate of 10% and a marginal propensity to import of 0.05. Economy B has a tax rate of 25% and a marginal propensity to import of 0.15. If the governments of both economies increase their spending by an identical amount, which economy will experience a larger increase in its total output, and why?

Four open economies (A, B, C, D) have an identical marginal propensity to consume of 0.8. Their tax rates and marginal propensities to import are listed below. Match each economy to the correct rank of its spending multiplier, from largest (1st) to smallest (4th).
True or False: Consider an open economy with a government where the marginal propensity to consume is 0.8. In this economy, a 5-percentage-point increase in the income tax rate (e.g., from 20% to 25%) will have a larger dampening effect on the spending multiplier than a 5-percentage-point increase in the marginal propensity to import (e.g., from 10% to 15%).
In an open economy with a government, the marginal propensity to consume is 0.75, the income tax rate is 20%, and the marginal propensity to import is 0.10. If autonomous investment spending increases by $50 billion, the total equilibrium output will increase by $____ billion. (Enter a numerical value only)
An economy experiences a $100 billion increase in autonomous export sales. Arrange the following events in the correct chronological order to trace the initial rounds of the resulting multiplier effect within the domestic economy.
A government plans to increase its spending to stimulate economic activity. In which of the following economic environments would this policy have the smallest impact on total national output?
