We consider whether banks should be allowed to set different ATM prices to their customers depending on whether they hold an account on the bank. In Massoud and Bernhardt (2002), without considering an interchange fee, a ban on price discrimination on ATM services increases total surplus. In the...

This paper presents evidence on the impact of bank-specific, regulatory, institutional, macro and financial development variables on competition in banking, using information at both national and bank level. With this aim, Lerner indices of market power are estimated using a sample of 10,479...

This paper analyses the effect of bank relationships on the interest rate and personaland real guarantees borne by a sample of small and medium-sized enterprises in theirindebtedness. The results of this paper indicate that the SMEs that work with fewer financialintermediaries obtain debt at a...

This paper tests Bester's (1985, 1987) prediction about the separating role ofcontracts that involve both interest rates and collateral in credit markets. To test thisprediction we use data from natural credit markets and controlled experiments. Using asample of credits to small and medium size...

In the context of an international unionized oligopoly, with vertical differentiation and downstream and upstream firms locked in a bilateral monopoly, the pattern of downstream mergers is investigated. In such a setting, a downstream merger leads to a reduction in the price of the inputs. Such...

This paper analyzes how the existence of upstream market power affects endogenous quality choice in a setting where two downstream firms are locked in a bilateral monopoly with their own input suppliers. The main result is that the degree of product differentiation is reduced as upstream market...

In this paper we analyze the strategic decisions of the government, the incumbent and the pirate in a market where the good is piratable. We show that deterred or accommodated piracy can occur in equilibrium, but pure monopoly cannot occur for any anti-piracy policy. We also show that the...

Este artículo trata el problema de cómo la competencia oligopolística es afectada por el desarrollo de las tecnologías que utilizan energías renovables dentro del marco de reducción de emisiones de CO2 y seguridad en el mercado eléctrico. En un modelo oligopolístico donde las empresas...

We consider two (symmetric) upstream firms producing independent goods that sell to consumers through symmetric retailers. The distinguishing feature of retailers is that they have a selling capacity, in the sense, that there is an upper limit in the total units of the two goods they can sell....
