Question 94

Friedman's statement is accurate in the long run.

Friedman's assertion that 'inflation is always and everywhere a monetary phenomenon' holds true when considering the long-term relationship between money supply and inflation rates. Over time, increases in the money supply lead to proportional increases in price levels, supporting the idea that inflation is fundamentally tied to monetary policy.

A) accurate in the long run

This option correctly identifies that, according to economic theory, inflation is fundamentally linked to the growth of the money supply over an extended period. Empirical evidence supports this view, showing that sustained inflation typically correlates with excessive monetary expansion.

B) but not supported by the data in the short run

While it is true that short-term fluctuations in inflation can be influenced by various factors beyond just monetary policy, this does not invalidate the long-run view. Short-run data may show discrepancies, but this does not contradict Friedman's long-term assertion.

C) refuted in theory

This option is incorrect as Friedman's theory has not been refuted; rather, it has been supported by a substantial body of economic literature. The assertion remains a cornerstone of monetary economics, consistently reaffirmed through theoretical and practical analyses.

D) but is supported by the data in the short run

Although some short-term data may align with Friedman's view, it does not encapsulate the full argument which emphasizes long-term trends. Thus, while there may be cases where monetary factors influence short-term inflation, this does not mean the broader statement is accurate in the short run.

E) accurate in the short run

This choice contradicts the fundamental premise of Friedman's statement, which asserts that inflation's primary driver is monetary policy, particularly observable in the long run. Short-run inflation can be influenced by various external factors, making this option misleading.

F) but is not supported by the data in the long run

This statement is fundamentally incorrect, as extensive historical data supports the correlation between money supply and inflation in the long term. It contradicts the core premise of Friedman's argument, which remains valid across various economic contexts.

G) refuted in theory

Similar to option C, this assertion is incorrect. Friedman's theory has not been refuted; rather, it remains a widely accepted explanation of inflation dynamics in economic discourse.

Conclusion

Friedman's statement is considered accurate in the long run because it aligns with observed economic patterns where inflation is largely driven by changes in the money supply. Other options either misinterpret the implications of short-term data or incorrectly suggest that the theory has been invalidated. Therefore, option A stands out as the definitive correct response.
