    Searches for new resonances in the diphoton final state, with spin 0 as predicted by theories with an extended Higgs sector and with spin 2 using a warped extra-dimension benchmark model, are presented using 139 fb−1 of √s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass

    MODELLING INFLATION IN SOUTH AFRICA: A MULTIVARIATE COINTEGRATION ANALYSIS

    We employ an expectations augmented Phillips curve framework to investigate the link between inflation, unit labour costs, the output gap, the real exchange rate and inflation expectations. Using multivariate cointegration techniques, we find evidence consistent with mark-up behaviour of output prices over unit labour costs. Most importantly, we find that the mark-up in the South African economy is much higher than in the U.S. For South Africa we find a markup of about 30 per cent: three times as high as the 10 per cent markup found for the U.S. Copyright 2005 Economic Society of South Africa.
