According to the neoclassical theory of distribution, in an economy described by a Cobb-Douglas production function, workers should experience high rates of real wage growth when: real interest rates are low. capital's share of income is growing rapidly. labor productivity is growing rapidly. real interest rates are high.

3 main differences between GDP deflator and CPI

1. GDP deflator measures prices of all g/s produced, CPI measures prices of all g/s BOUGHT BY CONSUMERS 2. GDP deflator only focuses on domestically produced items, CPI includes imports 3. GDP deflator assigns changing weights, while CPI assigns fixed weights to prices of different goods
