Huw David Dixon (/hju: devəd dɪksən/;^[4] born 1958) is a Britisheconomist. He has been a professor atCardiff Business School since 2006,^[5] having previously been Head of Economics at theUniversity of York (2003–2006) after being a professor of economics there (1992–2003),^[6] and theUniversity of Swansea (1991–1992),^[7] a Reader atEssex University (1987–1991) and a lecturer atBirkbeck College (University of London) 1983–1987.

Dixon graduated from his first degree inPhilosophy and Economics fromBalliol College, University of Oxford in 1980, and he went on to do his PhD atNuffield College, University of Oxford under the supervision ofNobel Laureate SirJames Mirrlees^[8] graduating in 1984.

Dixon was a fellow of theCEPR from 1991 to 2001,^[9] a member of theRoyal Economic Society council (1996–2001), and a fellow of theCes-ifo institute since 2000.^[10] He has been on the editorial board of theReview of Economic Studies (1986–1993),^[11] theJournal of Industrial Economics. He edited the Controversies section of theEconomic Journal (1994–99) and has been the chair ofthe Royal Economic Society Conference 1992.^[12]

Dixon has a wide scope in terms of the areas of economics he has researched and published in and he has been described as one of Europe's leading economists.^[13] The topics include:

1. Bertrand–Edgeworth models with strictly convex costs.Francis Edgeworth developed the analysis of the model ofBertrand competition in a setting where firms had constantmarginal cost up to capacity. Dixon explored how this could be generalized to the case of convex costs. He established the existence of a mixed-strategyNash equilibrium,^[14] and of anEpsilon-equilibrium in a large market,^[15] and in other aspects.^{[16][17][18][19]}
2. Strategic investment Models. The use of capital to alter the way firms compete inoligopoly by altering theirmarginal cost,^[20] orconjectural variations.^[21]
3. Bounded rationality. Dixon explored the implications of evolutionary ideas for oligopoly theory and learning.^[22] He also developed one of the first models ofendogenous aspirations in economics.^[23]
4. New Keynesian Macreconomics. Dixon was one of the first economists to examine the effect ofimperfect competition on the effectiveness of fiscal policy in his paperA simple model of imperfect competition with Walrasian features.^[24] This is an idea that was much explored in many other papers by him^[25] and more recently.^[26] This paper was the first to demonstrate in a simplegeneral equilibrium model that thefiscal multiplier could be increasing with the degree ofimperfect competition in the output market. The reason for this is thatimperfect competition in the output market tends to reduce thereal wage, leading to the household substituting away fromconsumption towardsleisure. Whengovernment spending is increased, the corresponding increase inlump-sum taxation causes both leisure and consumption decrease (assuming that they are both a normal good). The greater the degree of imperfect competition in the output market, the lower thereal wage and hence the more the reduction falls on leisure (i.e. households work more) and less on consumption. Hence thefiscal multiplier is less than one, but increasing in the degree of imperfect competition in the output market.

Other topics includeimperfect competition inmacroeconomics,nominal rigidity. Most of his work isNew Keynesian. Dixon supports theHigh Speed 2 development for theUnited Kingdom, and expressed his support in aFinancial Times article on 6 January 2012, along with other leading economists.^[27] He has contributed toThe Times Higher Education Supplement multiple times regarding economics.^[28][29]

Dixon has authored a bookSurfing Economics, which exploresNew Keynesian economics, theNatural Rate,Bounded Rationality,Social Learning and the meaning ofEconomics.
