This article is about a British economist. For the American economist, see David R. Henderson.
Patrick David HendersonCMG (10 April 1927[1][2] – 30 September 2018) was a British economist. He was the chief economist at the Economics and Statistics Department at the OECD during 1984–1992.[3] Before that he worked as an academic economist in Britain, first at Oxford (Fellow of Lincoln College) and later at University College London (Professor of Economics, 1975–1983); as a British civil servant (first as an Economic Advisor in HM Treasury, and later as Chief Economist in the Ministry of Aviation); and as a staff member of the World Bank (1969–1975). In 1985 he gave the BBCReith Lectures,[4] which were published in the book Innocence and Design: The Influence of Economic Ideas on Policy (Blackwell, 1986).
Henderson and Nigel Lawson appealed to then-Prime Minister Tony Blair to investigate the economic implications of the potential implementation of policies put forth by the UN Intergovernmental Panel on Climate Change (IPCC) findings.
Henderson and Ian Castles, a former head of the Australian Bureau of Statistics argued that the IPCC's projections of future emissions of greenhouse gases was flawed.[3] The IPCC's forecasts of global output were based on national GDP converted to dollars using market exchange rates. Henderson and Ian Castles were critical of the Special Report on Emissions Scenarios (SRES) report by the Intergovernmental Panel on Climate Change (IPCC) that was published in 2000.[6][7]: 159–185 [7]: 415–435 The core of their critique was the use of market exchange rates (MER) for international comparison, in lieu of the theoretically favoured PPP exchange rate which corrects for differences in purchasing power.[8] The IPCC rebutted this criticism.[9][10][11][12][13] Castles and Henderson later acknowledged that they were mistaken that future greenhouse gas emissions had been significantly overestimated.[14]
