Final answer:
Government shutdowns are more likely in the future if there is divided government, and they can impact economic growth and government revenue.
Step-by-step explanation:
Government shutdowns are a possibility in the future depending on the political climate and power dynamics between the executive and legislative branches. Divided government, where the president and at least one house of Congress are of opposite parties, increases the likelihood of shutdowns. For example, during the presidencies of Jimmy Carter and Ronald Reagan, government shutdowns occurred due to conflicts between the executive and legislative branches. Shutdowns can affect the variables in the national investment and savings identity by causing a reduction in economic growth and government revenue.
