Step 1: Understand the Quantity Theory of Money, which relates money growth to inflation in the long run. According to this theory, if the money supply grows faster than real output, the price level (and thus inflation) will increase proportionally.
Step 2: Recall that the natural rate of unemployment is determined by structural factors in the economy, such as labor market policies and technology, and is not affected by changes in the money growth rate in the long run.
Step 3: Recognize that the long-run real interest rate is determined by real factors like productivity and time preferences, and is not influenced by changes in the money growth rate, which primarily affects nominal variables.
Step 4: Understand that the real GDP growth rate depends on real factors such as capital accumulation, technological progress, and labor force growth, and is not directly affected by changes in the money growth rate in the long run.
Step 5: Conclude that increasing the money growth rate in the long run leads to a higher inflation rate, while real variables like natural unemployment, real interest rate, and real GDP growth remain unaffected.
