Determinants of relative poverty in advanced capitalist democracies

Using relative poverty measures based on micro-level data from the Luxembourg Income Study, in conjunction with pooled time-series data for 14 advanced capitalist democracies between 1970 and 1997, the authors analyze separately the rate of pretax/transfer poverty and the reduction in poverty achieved by systems of taxes and transfers. Socioeconomic factors, including de-industrialization and unemployment, largely explain pre-tax/transfer poverty rates of the working-age population in these advanced capitalist democracies. The extent of redistribution (measured as poverty reduction via taxes and transfers) is explained directly by welfare state generosity and constitutional structure (number of veto points) and the strength of the political left, both in unions and in government.
