Imagine two distinct historical economic environments. In Environment A, which existed for many decades, people generally believed that the overall price level would remain stable over the long term, regardless of short-term fluctuations. In Environment B, which emerged later, people began to closely watch the annual change in prices and quickly adjusted their wage demands and pricing strategies based on the most recent trends.

Analyze how a one-time, significant increase in the cost of imported oil would likely affect the path of the general price level over the subsequent few years in Environment A versus Environment B. In your analysis, explain the key difference in the underlying public behavior that drives the different outcomes.
