The correct option is:
Decrease in income, output and employment.
Explanation based on the report and Keynesian Theory:
- The Situation Described: The report highlights a global weakening of economic activity and a slack in consumer demand (a reduction in aggregate demand), leading to muted and softening inflation.
- Keynesian Application: According to Keynesian theory, in the short run, the levels of national income, output, and employment are strictly determined by the level of Aggregate Demand (AD).
- When consumer demand slacks (AD shifts to the left), firms face involuntary inventory accumulation.
- To adapt, producers cut down on production, which directly leads to a decrease in output and real income.
- As production falls, firms lay off workers, causing a decrease in employment.
