    EL COSTO DE FALLA RESIDENCIAL EN CHILE: UNA ESTIMACION USANDO LA CURVA DE DEMANDA*
    (2005) José Miguel Benavente; Alexander Galetovic; Ricardo Sanhueza; Pablo Serra
    This paper estimates the residential outage cost in Chile’s Central Interconnected System (SIC), using consumer’s willingness to pay for energy. We first estimate the cost of reducing energy consumption efficiently, that is only the less valuable kWh (as indicated by the market demand curve) are rationed. Then we estimate the per-kWh cost of rationing by cutting off service. We find that the outage cost varies

    LA REGULACION DEL TRANSPORTE DE CARGA EN SANTIAGO: CARACTERISTICAS, EVALUACION Y PROPUESTAS
    (Pontifical Catholic University of Chile, 2003) Carlos Barrera-Díaz; Alexander Galetovic; Ricardo Sanhueza
    Este trabajo evalúa la regulación del transporte de carga en Santiago. Concluimos que gran parte de las regulaciones restringen cuantitativamente el uso y el acceso a las vías, y que los agentes las perciben como erráticas, lo que genera incertidumbre para la toma de decisiones. Argumentamos que estas restricciones no sólo son costosas sino que también ineficaces, ya que el principal determinante del volumen de carga transportado es el nivel de actividad económica en Santiago, que es en gran medida independiente de las políticas adoptadas para el transporte de carga. Las concesiones urbanas, que serán implementadas próximamente en Santiago, mitigarán algunos de los problemas causados por el transporte de carga. Ellas no sólo aumentarán la oferta de vías sino que también harán que los usuarios paguen la externalidad que generan cuando las utilizan

    Vertical Mergers and Competition with a Regulated Bottleneck Monopoly
    (De Gruyter, 2009) Alexander Galetovic; Ricardo Sanhueza
    Abstract Consider a bottleneck monopoly whose access charge is regulated above marginal cost and produces an essential input used by an oligopoly of downstream firms. Should the monopolist be allowed to vertically integrate into the downstream market? Policy makers often argue that the vertically integrated subsidiary enjoys an undue advantage, because it receives access at marginal cost. We show that there is no undue advantage.With perfect competition downstream vertical integration is irrelevant because the subsidiary substitutes downstream output one-to-one and faces a per-unit opportunity cost equal to the access charge.With an oligopoly consumers and the bottleneck monopoly gain with vertical integration. By contrast, competitors lose oligopolistic rents. Social welfare increases, unless output is redistributed towards a very inefficient vertically integrated firm.
