Jackson, L FraserKhaled, Mohammed S2018-01-222022-07-112018-01-222022-07-1120182018https://ir.wgtn.ac.nz/handle/123456789/20312Data on the proportions in each of the labour force status categories sum to one and form a composition. Using the log ratios of the parts and a transform to orthogonal coordinates in a lower dimension provides a consistent way of handling this constraint. This paper emphasizes that a composition is a vector of values not a single number and shows a coordinate for employment participation is directly associated with a coordinate defining the level of search by those without jobs.The model is extended to deal with heterogeneity due to gender and current status and to generate a new analysis of the gross flows data. The associations observed provide evidence that micro decisions can be strongly modified by the macro situation and a Keynesian demand driven framework fits very well.pdfen-NZComposition modelsUnemploymentGross flows dataLabor force statusLabour force statusUS labor forceU.S labour forceLog ratio modelsRationingTexthttp://www.victoria.ac.nz/sef/research/sef-working-papers
