Abstract generation in progress

The macroeconomics community recently received a poignant piece of news: Christopher A. Sims, the 2011 Nobel laureate in Economics and the pioneer of the Vector Autoregression (VAR) method, has passed away.

Over the past half-century of macroeconomic history, few methods have profoundly changed empirical research as much as VAR. In 1980, Sims proposed a groundbreaking idea in his classic paper “Macroeconomics and Reality” (Sims, 1980): macroeconomists often assume economic structures too early, but truly robust research should allow the data itself to reveal the dynamic relationships between variables.
