Tim Bollerslev is an influential economist known for his work in financial econometrics, particularly in modeling financial market volatility. He developed the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model, which helps analyze and forecast changes in asset prices by accounting for varying levels of volatility over time.

Bollerslev's contributions have significantly impacted how economists and finance professionals assess the behavior of markets, especially during periods of uncertainty.
