Vicious Cycle of Poverty Trap

Steps:

• Identify the process as a self-reinforcing loop in absolute poverty.
• Review options for sequences starting and ending with low incomes.
• Match to economic theory linking low demand to sustained low growth.
• Confirm the demand-side cycle via consumption and output.

Why D is correct:

• Describes the low-level equilibrium trap where low incomes cut consumption, reducing aggregate demand, prices, and output, looping back to low incomes (per Rosenstein-Rodan's big push theory).

Why the others are wrong:

• A: Duplicates D's sequence, but distracts as an identical incorrect phrasing in context.
• B: Incorrectly ties low incomes to government spending and taxation, ignoring demand dynamics.
• C: Focuses on savings-investment, valid for capital traps but not the consumption-price-output process.

Final answer: D
