The strong consistency of regression quantile statistics (Koenker and Bassett [4]) in linear models with iid errors is established. Mild regularity conditions on the regression design sequence and the error distribution are required. Strong consistency of the associated empirical quantile...

This paper generalizes a model of monopolistic competition attributable to Spence (1976). Firms produce symmetrically differentiated products with declining or U-shaped average costs. Free entry drives profits to zero in equilibrium. Spence finds that when firms behave "competitively," in a...

In finance, there is growing interest in quantile regression with the particular focus on value at risk and copula models. In this paper, we first present a general interpretation of quantile regression in the financial market. We then explore the full distributional impact of factors on returns...
