This paper extends the tourist test model proposed by Rochet and Tirole (2011) by incorporating the government in order to take into account informality (understood as tax evasion in cash payments) and the net social cost of cash usage. These two elements are relevant in developing countries,...

I model multimarket competition when consumers value firm scope across markets. Such competition is surprisingly common – consumers in many industries prefer firms that operate in more geographic and/or product markets. I show that these preferences permit firms of differing scopes to coexist...

We investigate the trade-off between financial stability and competition policy by focusing on the merger of ABN AMRO and Fortis Bank NL in the Dutch retail banking market. The financial crisis delayed the completion of the merger giving rise to anti-competitive behavior in the transitory...

We show how price leadership bans, imposed as part of the European Commission's State aid control on all main mortgage providers except the largest bank, shifted the Dutch mortgage market from a competitive to a collusive price leadership equilibrium. In May 2009, mortgage rates in the...

We analyze a large merger in the Dutch banking market during the financial crisis using disaggregated data. Based on a merger simulation model, we evaluate merger-induced changes in the interest rates for savings accounts. We find that the merging banks decreased interest rates by 3 to 5 percent...

Inhaltliches Fundament zahlreicher Stabilitäts-, Produktivitäts- und Rentabilitätsanalysen zur Bankenwirtschaft ist die präzise Einschätzung der Wettbewerbsverhältnißse. Aus theoretischer Sicht steht hierzu eine ganze Reihe an alternativen Konzepten zur Verfügung. Gleichwohl gestaltet...

We propose a heteroscedastic regression model to identify the determinants of the dispersion in interest rates on loans granted to small and medium sized enterprises. We interpret unexplained deviations as evidence of the banks' discretionary use of market power in the loan rate setting process....

This paper discusses the relationship between bank size and risk-taking under Pillar I of the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we find that small banks (and hence small borrowers) may profit from the introduction of an internal ratings based...

We present a banking model with imperfect competition in which borrowers' access to credit is improved when banks are able to transfer credit risks. However, the market for credit risk transfer (CRT) works smoothly only if the quality of loans is public information. If the quality of loans is...
