Abstract We establish bounds for the representation dimension of skew group algebras and wreath products. Using this, we obtain bounds for the representation dimension of a block of a Hecke algebra of type A, in terms of the weight of the block. This includes certain blocks of group algebras of symmetric groups.
We show theoretically that the poor can benefit from price changes induced by higher income inequality. As the number of poor increases, the market for products aimed toward the poorgrows, and such products become more profitable. As a result, there are circumstances where an increase in income inequality associates with higher purchasing power of the poor. Using cross-country data on the price…
