The problem of inserting a complex propagator in the crossed channel of the square diagram is considered. The propagator is spectrally represented and the square diagram with full propagator insertion is expressed as a spectral integral of square diagrams over an internal mass variable. The analytic properties of such diagrams in two complex variables, one internal mass and one external energy,...

This paper examines the distributional impacts from (i) harmonizing prices for carbon dioxide emissions across sectors and EU countries (ii) using alternative rules revenue distribution. We develop a numerical multi-country multi-sector general equilibrium model of EU-27 economy which resolves household income deciles, based on micro-survey data expenditure income, markets fossil fuels, electri...
