We study the impact of government spending shocks on the distribution of income and wealth between cohorts and the associated welfare effects in a dynamic stochastic overlapping generations model with two types of households, Ricardian households and rule-of-thumb consumers. We demonstrate that an unexpected increase in government spending decreases income and wealth inequality. In contrast to the conventional wisdom that the financing of government expenditures by debt rather than taxes especially burdens young generations, we find that debt-financing also harms Ricardian households during retirement. The crucial element in our analysis is a wealth effect that results from the decline in the price of capital due to higher government debt.

According to empirical studies, the life cycle of labor supply volatility exhibits a U-shaped pattern. This may lead to the conclusion that demographic change induces a drop in output volatility. We present an overlapping generations model that replicates the empirically observed pattern and study the impact of demographic transition on output volatility. We find that the change in age-composition itself has only a marginal influence on output volatility as the mitigating effect of lower labor supply volatility is compensated by higher labor supply. Instead, the driving force behind the Great Moderation in our model is the downward shift of the age-specific labor supply volatility curve.
