Arrange the effects of unanticipated inflation on different economic agents in the correct sequence: A) Borrowers experience a decrease in the real value of their debt, B) Lenders see a reduction in the purchasing power of their returns, C) Savers find their savings diminished in value, D) The overall economy adjusts to new price levels.

Unanticipated inflation affects different groups in various ways. First, when inflation occurs unexpectedly, borrowers benefit because the real value of the money they owe decreases, making it easier for them to repay their debts. Meanwhile, lenders are hurt because the money they receive back has less purchasing power than when they lent it, reducing the value of their returns. Savers are also negatively impacted because their savings lose value over time due to rising prices, making it harder to buy what they need. Finally, as these changes happen, the overall economy must adjust to the new price levels, affecting all economic agents and leading to shifts in spending and investment behavior.
