Research

In the 1980s, Goldberg was a key member of the research community that elucidated the properties of dynamical systems generated by rational maps of the Riemann sphere. Alone[1] and in collaboration with John Milnor,[2] Goldberg used rotation subsets of the circle to classify polynomial dynamical systems in one complex variable based on their fixed points.

In 1993, Goldberg left academia to pursue a career in quantitative finance at Barra (now MSCI), and she has been a proponent of research that combines best practices from industry and the university.[3] Early in the 2000s, in collaboration with Kay Giesecke, she developed a top down methodology based on point processes that is used to assess complex credit derivatives.[4][5][6] Beginning in 2006, Goldberg, in collaboration with Guy Miller and Jared Weinstein, developed a patented extension of quantitative risk management tools to extreme events and market turbulence.[7] Goldberg also holds two patents on industry-standard multi-asset class risk models[8][9] and one patent on incomplete information credit models.[10] Early in the financial crisis of 2007–08, Goldberg warned against the risks associated with the reliance on Gaussian models.[11] Risk parity strategies have been claimed by a number of practitioners to deliver investment performance superior to traditional strategies, and have been especially popular since the financial crisis of 2007-08. In collaboration with Robert M. Anderson (economist) and Stephen Bianchi, Goldberg demonstrated that long-horizon performance of risk parity strategies is qualitatively similar to long-horizon performance of traditional strategies after accounting for realistic financing and trading costs, and that risk parity substantially underperforms traditional strategies in certain time periods.[12] Subsequent research by the same team extends the findings to the more general class of dynamically levered strategies, and it reveals high sensitivity of strategy performance to a previously unidentified source of risk: the co-movement of leverage with return to the underlying portfolio that is levered.[13] They also pointed out that levered strategies involving bonds, including risk parity, are very vulnerable in a rising interest rate environment,[13][14][15] the precise environment that many analysts predict for the coming years.
