### Life

Clive Granger was born in Swansea, U.K. At the age of six, while his father was serving in WWII, the family moved to Cambridge. He applied to Nottingham University to study mathematics and economics. He received his Ph.D. in 1956. In 1974 he became a professor at the University of California, USA. Granger wrote several books, covering such subjects as time series analysis and forecasting, statistical theory and applied statistics.

### Work

Most macroeconomic time series follow a stochastic trend, so that a temporary disturbance in, say, GDP has a long-lasting effect. These time series are called nonstationary. Clive Granger demonstrated that the statistical method used for stationary time series could yield wholly misleading results when applied to analysis of nonstationary data. He developed methods that can be used to analyze the relations between for example wealth and consumption and exchange rates and price levels.
