Thomas Sargent at podium and Chirs Sims standing to the left.
Chris Sims will have as strong an impact as Sargent because techniques can be applied by all schools of thought. Sims, through vector autoregressive models, VAR, focuses on the impact of shocks to the economy. We can now measure shocks through time and see how they will play through the economy. Every econometric course focused on macroeconomics will have to learn the techniques of Sims.
We congratulate both for having a profound change on economics.
