What is the theoretical significance of the 'Real Business Cycle (RBC)' theory in modern macroeconomic modeling regarding economic fluctuations?
A. It attributes economic cycles primarily to monetary shocks and sticky nominal wages
B. It explains economic fluctuations as efficient responses to real shocks, such as technological changes, within competitive markets✓ Correct Answer
C. It emphasizes speculative bubbles in asset markets as the sole cause of macroeconomic instability
D. It relies on government fiscal stimulus to smooth out short-run output volatility
💡 Solution & Explanation
Real Business Cycle theory views economic fluctuations as efficient responses to exogenous shocks to real variables like technology, rejecting the Keynesian view that recessions stem from market failures or nominal rigidities. It assumes competitive markets, flexible prices, and intertemporal substitution of labor. Critics argue that the model struggles to explain large voluntary fluctuations in employment observed during severe economic downturns. Productivity shocks serve as the fundamental driving force in standard RBC formulations.
