Robert F. Engle (Nobel laureate in Economics)

Robert F. Engle is an American economist renowned for his work on analyzing financial markets, particularly in understanding how economic data varies over time. In 2003, he received the Nobel Prize in Economic Sciences for developing models that help predict and measure volatility, or fluctuations, in financial markets. His methods, such as the Autoregressive Conditional Heteroskedasticity (ARCH) model, allow economists and analysts to better assess risk and make informed decisions. Engle's contributions have significantly advanced the field of econometrics, shaping how we understand and respond to economic uncertainty.
