Seaports provide multiple services to ships, cargo and passengers. The size of the port and type of service they offer are two key elements when deciding whether competition is feasible and how to promote it or, conversely, regulation is needed. Analysing this requires a profound knowledge of...

Trujillo, Martín, Estache, and Campos provide empirical evidence on the impact that private participation in infrastructure has had on key macroeconomic variables in a sample of 21 Latin American countries from 1985–98. Specifically, they look at the effects on GDP per capita, current public...

La industria portuaria se caracteriza por la gran diversidad de actividades que la componen. El sector público y el privado suelen convivir en esta industria de forma que el primero regula las actividades que las empresas privadas desarrollan en el ámbito portuario. De esta manera, cobra una...

After Vickrey's view, Mohring constructed a microeconomic model to determine the optimal frequency of buses serving a corridor with fixed demand. The main result was that frequency should be proportional to the square root of demand. The role of users' costs was shown to be crucial. This...

We argue that prevailing technologies for bus fare payment and boarding rules make boarding and alighting time t - usually treated as an exogenous parameter - a relevant decision variable in the optimisation of bus services. We show that diminishing t reduces optimal bus frequency and increases...

Using a single line model, it has been shown recently that the presence of a stringent financial constraint induces a less than optimal bus frequency and larger than optimal bus size. This occurs because the constraint induces a reduction of the importance of users’ costs (their time); in the...
