The interpretation by Duskin and Glenn of abelian sheaf cohomology as connected components of a category of torsors is extended to homotopy classes. This is simultaneously an extension of Verdier’s version of Čech cohomology to homotopy.

My focus is on recent additions to accumulated learning, in Issing’s words, that have pro...

Using an annual data series on inequality in Australia since 1941, six possible determinants of inequality are tested: unionisation, the minimum wage, immigration, trade, growth, and unemployment. To properly assess the impact of immigration and trade on the income distribution, new measures of the human capital of the average immigrant, and human capital embodied in imports, are developed. Gra...
