Hi All, Just a note on this. This was a preliminary draft circulated internally as part of a workshop series. It was not meant for wide distribution. There should be an updated and more complete working paper version coming soon. I will pass that along to the group when it is released. Happy to answer any questions about the research in the meantime though.
