Investment based question

Question

Utilizing the consumption and saving data in given table and supposing investment is $16 billion, describe saving and planned investment at the $380 billion level of domestic output? Determine saving & actual investment at that level? Determine saving and planned investment at the $300 billion level of domestic output? Describe levels of saving & actual investment? Employ the concept of unplanned investment to describe adjustments toward equilibrium through both the $380 and $300 billion levels of domestic output.

Answer 1

At the $380 billion level of GDP, saving is $24 billion; planned investment will be $16 billion (from the question). This deficiency of $8 billion of planned investment causes an unplanned $8 billion rise in inventories.  Actual investment is $24 billion (= $16 billion of planned investment as well as $8 billion of unplanned inventory investment), matching the $24 billion of actual saving.

    At the $300 billion level of GDP, saving is $8 billion; planned investment wills $16 billion (from the question). This excess of $8 billion of planned investment causes an unplanned $8 billion decline in inventories. Actual investment is $8 billion (= $16 billion of planned investment minus $8 billion of unplanned inventory disinvestment) matching the actual of $8 billion.

   While unplanned investments in inventories takes place, as at the $380 billion level of GDP, businesses revise their production plans downward and GDP drop. While unplanned disinvestments in inventories take place, as at the $300 billion level of GDP; businesses revise their production plans upward and GDP increase.  Equilibrium GDP—in this case, $340 billion—takes place where planned
