Quantifying the Effects from Horizontal Mergers in European Competition Policy

This paper starts from a recent case to study how merger analysis in Europe may potentially be improved through simulation analysis. Starting from the geographic market definition in the Merger Decision, we formulate and estimate an oligopoly model with differentiated products. The model is simulated to account for the changed multiproduct ownership structure after the merger. We show how our f...

Strong Topological Regularity and Weak Regularity of Banach Algebras

In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context. We show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. Then we consider strong topological regularity of certain concrete algebras. Moreover we obtain ...

WEAK AND STRONG DUALITY THEOREMS FOR FUZZY CONIC OPTIMIZATION PROBLEMS

The objective of this paper is to deal with the fuzzy conic program- ming problems. The aim here is to derive weak and strong duality theorems for a general fuzzy conic programming. Toward this end, The convexity-like concept of fuzzy mappings is introduced and then a speci c ordering cone is established based on the parameterized representation of fuzzy numbers. Un- der this setting, duality t...

Bank mergers, competition and liquidity

We provide a model of the impact of bank mergers on loan competition, individual reserve management and aggregate liquidity risk. Banks hold reserves against liquidity shocks, refinance in the interbank market and compete in a differentiated loan market. A merger creates an internal money market that induces financial cost advantages and may increase reserve holdings. We assess the liquidity ri...
