Griffith is currently Research Director of the IFS and co-director of the Centre for the Microeconomic Analysis of Public Policy (CPP). She was elected President of the Royal Economic Society from 2019 to 2020.[9]
She is Professor of Economics at the University of Manchester, a Fellow of the British Academy, a Fellow of the Econometric Society, a Foreign Honorary Member of the American Economic Association and a Research Fellow of CEPR. Rachel won the Birgit Grodal award in 2014, was awarded a CBE in for services to economic policy in 2015 and was made a Dame for services to economic policy and education in 2021. She also served as Deputy Chair of the Economics sub-Panel of the Research Excellence Framework. Currently, she has her second ERC Advanced Grant to study behavior of consumers and firms to see how government policy will impact food markets.[10]
Griffith's presidential address to the European Economic Association at the University of Mannheim, Germany entitled "Gluttony and Sloth? Labour Market Nonseparabilities and the Rise in Obesity",[11][12] reflected her recent research into the relationship between changes in relative food prices and the nutritional quality of households’ shopping baskets.[13]
In her Royal Economic Society Public Lecture 2015, "Does Starbucks Pay Enough Tax", Griffith argued that corporate tax should be charged like VAT.[14] Griffith stated that the current system of corporate taxation is outdated and taxing corporate profits in the location where value is created is not very meaningful. She suggested taxing profits at the destination of sales rather than at the source of profits would be an improvement.[15][16] Griffith cited two papers, one by Auerbach and Devereux (2012),[17] the other by Devereux and Vella (2014),[18] in support of her case. Griffith's previous research in this area considers how influential corporate income taxes are in determining where firms choose to legally own intellectual property, i.e. the way in which intellectual property accounts for firms' assets and if they can be used by firms to shift income offshore to reduce their corporate income tax liability.[19]
