Abstract Using a broad panel of advanced economies, we document that increases in GDP per capita are associated with systematic shift the composition value added to sectors intensive high-skill labour, process label as skill-biased structural change. It follows further development these economies leads an increase relative demand for skilled labour. We develop quantitative two-sector model this...

China has witnessed rapid increases in the skill premium over last few decades. In this paper, we study short-run effect of capital goods imports on China. The surge imports, which embody advanced technology, can explain rising demand for We exploit regional variations import exposure stemming from initial differences structure and instrument growth using exchange rate movements.

For a finite group G, we introduce the complete suboperad $Q_G$ of categorical G-Barratt-Eccles operad $P_G$. We prove that $P_G$ is not finitely generated, but generated and genuine $E_\infty$ G-operad (i.e., it $N_\infty$ includes all norms). G cyclic order 2 or 3, determine presentations object conclude with discussion algebras over $Q_G$, which call biased permutative equivariant categories.
