We study the asset allocation and consumption decisions of an investor with recursive utility and a finite investment horizon. We provide an approximate analytical solution under a stochastic investment opportunity set. The solution becomes exact when the elasticity of intertemporal substitution is...

We argue that shocks to credit supply by shadow and retail banks were key to understanding the behavior of the US economy during the Great Recession and the Slow Recovery. We base this result on an estimated DSGE model featuring a rich representation of credit flows. Our model selects the two...

We use two randomized controlled trials in Bangladesh to study a simple water conservation technology for rice production called "Alternate Wetting and Drying (AWD)." Despite proven results in agronomic trials, our first experiment shows that AWD only saves water and increases profits in villages...
