Before revision:  We solve a calibrated model with standard constant relative risk aversion utility and show that asymptotic MPCs can be zero in empirically plausiblesettings, implying an increasing and large saving rate of the rich and high wealth inequality  .
After revision:  We solve a calibrated model with standard constant relative risk aversion utility and show that asymptotic MPCs can be zero in empirically plausiblesettings, implying an increasing and large saving rate of the rich and high wealth inequality (small Pareto exponent) as observed in the data .
