Johansen's legacy to CGE modelling: Originator and guiding light for 50 years

Fifty-six years ago Norwegian economist, Leif Johansen, gave us the first CGE model. While Johansen was first, he is not the father of the whole field. CGE modelling in different styles sprang largely independently from several sources. This paper describes Johansen's model and how his style of CGE modelling took root in Australia in the 1970s and from there spread to the rest of the world. Today, thousands of economists from nearly every country are undertaking Johansen-style CGE modelling to elucidate policy questions in trade, taxation, environment, labour markets, immigration, income distribution, technology, resources, micro-economic reform and macro stabilization.
