We extend the global games method to the class of finite player, finite action games that includes games with strategic complements, games with strategic substitutes, and arbitrary combinations of the two. Our result is based on common order properties present in both strategic complements and...

We investigate the accuracy of UPP as a tool in antitrust analysis when there are cost efficiencies from a horizontal merger. We include model-based, merger-specific cost efficiencies in a tractable manner and extend the standard UPP formulation to account for these efficiencies. The efficacy of...

We characterize x-directional monotone comparative statics in function spaces, generalizing the results in Barthel and Sabarwal (2018) for finite-dimensional Euclidean spaces, and showing that their proofs generalize to infinite-dimensional spaces. Our generalizations include those for...

One explanation provided for the relatively high and increasingly stable spreads for moderate - sized IPOs ($20-$80 million) documented in Chen and Ritter (2000) is that issuing firms focus less on price and more on a combination of investment bank-differentiating factors (such as underwriter...
