“Dynamic Choice with Constant Source-Dependent Relative Risk Aversion” (undergoing revision)
“Smooth Ambiguity Aversion Toward Small Risks and Continuous-Time Recursive Utility” Journal of Political Economy, August 2013. You can experiment with the code that generates the examples of Section 2 by copying and pasting this F# script into this web page (no installation needed).
Equivalent Scala program. These are programs relying on mutable state; here are purely functional versions in Scala and Haskell. (To run efficiently, compile the Haskell version using “ghc --make –O2 funcRec.hs”.)
