This paper describes and tries to quantify the effects of some factors that have affected costs of state owned electric utilities in Mexico (energy losses, fuel and labor). It is noted that the impact of the increases in fuel prices on the electric utilities' total cost in the last years has...

We developed a model to analyze the short term relationship between mobile phone charges per rounded minute and per second, in a context where tariffs are freely determined. We assumed profit maximizing firms and an exponential distribution for mobile call duration. Among the results, we found...
