We establish nonparametric identification in a class of so-called index models using a novel approach that relies on …

We develop a programming algorithm that predicts a balanced-panel mix-adjusted house price index for arbitrary spatial …

This paper introduces the Werden-Froeb Index (WFI) to assist in evaluating merger-specific efficiencies in horizontal … mergers. The index measures the weighted average reduction in marginal costs required to restore pre-merger equilibrium prices … has relatively low information requirements. We propose to use the index as a natural complement to concentration measures …
