Two economists analyze the impact of a sudden, large increase in consumer confidence. Economist A compares the economy's initial stable state (before the increase) with the final stable state (after all adjustments). Economist B also studies the transitional period, tracing the path of variables like output, inflation, and interest rates as the economy moves from the initial to the final state. Explain why Economist B's method of examining this period of imbalance offers a more profound understanding of the economic model's behavior.
