Robert Engle won the Nobel Prize in Economics in 2003 for his work on econometric techniques to deal with time-varying volatility, specifically for the development of autoregressive conditional heteroscedasticity (ARCH) and generalized autoregressive conditional heteroscedasticity (GARCH) models. These models are widely used in finance and economics to model and forecast volatility, and have been influential in risk management and asset pricing.
