Cargo handling activities involve various heterogeneous outputs, e.g. general cargo, containers, dry and liquid bulk and so on. These activities in ports, however, have been usually analysed using aggregate descriptions of output such as total tons moved. The main purpose of this article is to...

Because of their critical strategic role, ports have all traditionally been subject to some form of government control even if the legal form and the intensity of this control have varied across countries. The member countries of the European Union have not been different from the rest of the...

This paper is a first attempt at documenting efficiency levels in Africa's electricity firms, their evolution and the sources of this evolution. The analysis is based on a sample of 12 operators providing services in the 12 country members of the Southern Africa Power Pool. We focus on the...

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...

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...
