Suppose that every additional 3 percentage points in the investment rate boosts GDP growth by 1 percentage point. Assume also that all investment must be financed with consumer saving. Note: Investment rate = Investment/GDP The economy is currently characterized by Consumption: $11 trillion Saving (= Investment): $3 trillion GDP: $14 trillion If the goal is to raise the growth rate by 2 percentage points, a. by how much must investment increase? billion b. by how much must consumption decline? billion

Suppose in a closed economy with positive national saving, consumption is 70% of GDP, taxes net of transfers are 30% of total consumption and investment, and government spending is less than investment. Which of the following statements is true? (a) Public saving is greater than private saving. (b) Private saving is 9% of GDP. (c) Public saving is less than 10% of GDP. (d) Investment is less than 10 Also give Why other False.
What does it mean by the logic: When output is too low, what needed is an increase in demand for goods and services. Investment is one component of demand, and saving equals investment. Therefore, if the government could just convince households to attempt to save more, then investment and output would increase.
