Stock prices and consumption: A new variable in the consumption function?

This thesis examines the significance of the real interest rate and stock prices as explanatory variables in the aggregate consumption function. This study applies the methodologies of OLS regression analysis and tests of cointegration to examine the relationship between stock prices and consumption. The empirical results suggest that stock prices are a significant factor in the modified aggregate consumption function. Consumers, perceiving stock prices to be an indicator of their wealth, are making more expenditures on durable goods as they perceive increases in stock values to be permanent. Finally, the results of the tests for cointegration suggest that there is no long-run equilibrium relationship between stock prices and consumption.
