Recent empirical evidence suggests that financial networks exhibit a core periphery network structure. This paper aims at giving an economic explanation for the emergence of such a structure using network formation theory. Focusing on intermediation benefits, we find that a core periphery...

There is a growing concern that U.S. merger control may have been too lenient, but empirical evidence remains limited. After reviewing event studies as a method to acquire empirical insights into the competitive effects of mergers, I propose a novel application using Hoberg-Phillips TNIC data....

We assess the influence of competition and capital regulation on the stability of the banking system. We particularly ask two questions: i) how does capital regulation affect (endogenous) entry; and ii) how do (exogenous) changes in the competitive environment affect bank monitoring choices and...

Using a large dataset of firm-bank and ownership information for 23 European countries over 2008-2015, we study the dynamics of bank relationships after corporate acquisitions and the effects of changing banks on firm performance. Foreign acquirers do not rely on internal capital markets but...

This paper investigates the extent of the holdup underinvestment problem in a buyer-seller relationship in which the seller has private information about his alternative trading opportunities. Theory predicts that, compared with a situation in which outside options are publicly observed, the...

This paper examines how a radical technological innovation affects alliance formation of firms and subsequent network structures. We use longitudinal data of interfirm R&D collaborations in the biopharmaceutical industry in which a new technological regime is established. Our findings suggest...

This paper introduces the Small World model (Watts and Strogatz, Nature, 1998) into the theory of economic growth and investigates how increasing economic integration affects firm size and efficiency, norm enforcement, and aggregate economic performance. When economic integration is low and...

Halal certification of financials product may reduce transaction costs for its buyers when it provides a trusted standard for investors that seek to comply with Islamic law. However, we show that in practice it takes considerable amounts of time (20 days ) and money (USD 122,000) to obtain a...

We consider price-fee competition in bilateral oligopolies with perfectly-divisible goods, non-expandable infrastructures, concentrated agents on both sides, and constant marginal costs. We define and characterize stable market outcomes. Buyers exclusively trade with the supplier with whom they...

One of the reasons why regulators are hesitant about permitting price competition in healthcare markets is that it may damage quality when information is poor. Evidence on whether this fear is well-founded is scarce. We provide evidence using a reform that permitted Dutch health insurers and...
