Store brands are thought to improve a retailer's position relative to leading brand manufacturers and to reduce retail prices. Steiner (2004) offers a characterization of typical industry structures by considering the relationship between interbrand and intrabrand elasticities. We estimate a...

A large consensus now seems to take for granted that the distributions of empirical returns of financial time series are regularly varying, with a tail exponent b close to 3. We develop a battery of new non-parametric and parametric tests to characterize the distributions of empirical returns of...
