This paper analyzes the macroeconomic effect of population aging on the aggregate demand for goods and services between 2000 and 2040. As the composition of goods and services consumed varies over the life cycle, the aggregate demand structure is likely to change as well when the population is...

We estimate the extent to which idiosyncratic and disaggregate macro shocks (such as regional and industry shocks) are not shared in the economy. Comparing the degree to which idiosyncratic and disaggregate macro shocks are not shared grants a deeper understanding as to why the economy lacks in...

Much of the literature on time inconsistency has studied the external commitment devices that individuals use to address their self-control problems: tying oneself to the mast, staying away from temptation, holding illiquid assets, or "asking controls" from others. This paper, by contrast,...

On an international post World War II dataset, we use an iterated GMM pro- cedure to estimate and test the Campbell-Cochrane (1999) habit formation model. In addition, we analyze the predictive power of the surplus consumption ratio for future asset returns. We find that, although there are...

This paper adresses the issue of the optimal speed of economy-wide restructuring from a state-owned to a privately-owned economy. The analysis is led from a general equilibrium perspective, focusing on the role of endogenously generated capital accumulation. Sensitivity of the optimal speed of...

Marginal income taxes may have an insurance effect by decreasing the effective fluctuations of after-tax individual income. By compressing the idiosyncratic component of personal income fluctuations, higher marginal taxes should be negatively correlated with the dispersion of consumption across...

We survey the microfoundations, empirical evidence and estimation issues underlying the aggregate matching function. Several microeconomic matching mechanisms have been suggested in the literature with some successes but none is generally accepted as superior to all others. Instead, an aggregate...

We estimate tax multipliers in a "Blanchard-Yaari" consumption model where Ricardian equivalence is broken because the private sector discounts the future at a faster rate than the real rate of interest. The model fits U.S. data since 1955 extremely well-entailing a discount wedge of around 20...
