Over the last twenty years there has been a deep concentration process in the Pension Fund Manager (AFPs) industry in Chile (from 21 firms in 1994 to only 6 in 2012). A major concern with the concentration of this industry is that firms might be able to exercise market power. However,...

Este trabajo cumple con dos objetivos principales. En primer lugar, se estima la función de costos de las administradoras de fondos de pensiones en Chile usando datos de panel desde 2000 a 2007. Se encuentran importantes economías de escala en la provisión de los servicios financieros,...

We consider the portfolio selection problem in the accumulation phase of a defined contribution pension scheme in continuous time, and compare the mean-variance and the expected utility maximization approaches. Using the embedding technique pioneered by Zhou and Li (2000) we first find the...

We consider the portfolio selection problem in the accumulation phase of a defined contribution (DC) pension scheme. We solve the mean-variance portfolio selection problem using the embedding technique pioneered by Zhou and Li (2000) and show that it is equivalent to a target-based optimization...

When consumers concentrate their purchases at a single firm, a firm that offers more products than its rivals can gain market share for all its other products, as well. These spillovers induce firms to compete by offering a greater variety of products rather than lower prices, and a natural...

Automated teller machine (ATM) networks are a key component of payments systems. A number of competing theoretical models have been developed to examine fees associated with ATM transactions. A common feature of these models is that they imply that the elimination of interchange fees will cause...

This paper analyses whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models – a Stackelberg model, two varieties of a Cournot model, and a perfect...
