Paying for tax reform is easy—as long as the White House and Congress don’t mind fixing climate change at the same time.
That’s the counterintuitive pitch of Robert Litterman, a financial economist who became famous on Wall Street in the 1990s for co-inventing a method (PDF) for allocating assets within a portfolio. He went on to become Goldman Sachs Group Inc.’s top risk manager and then led its quantitative asset management investments until he left in early 2010. Today, he’s the chairman of the Risk Committee at Kepos Capital.
