Merger wave in a small world: Two views
I attempt a more balanced assessment of mergers in terms of systemic risk versus other effects. First, using the simplest network model, I illustrate how mergers can increase systemic risk by reducing the degree of separation among firms. Then, recasting the firms in a simple economic model that features consumers explicitly, I show how a merger wave – a contagious urge to merge – can occur and what benefit it may bring to consumers. Together, these two models suggest that there is a tradeoff to consider: While a merger wave may result in higher systemic risk, it may also bring about higher consumer welfare.
