Profitability at a period of time is defined as the value of outputs produced by a production unit divided by the corresponding cost. Using some earlier work by O’Donnell, the paper provides a decomposition of profitability growth over two periods into various explanatory factors. The...

This paper presents an application of a mechanism that provides incentives to promote transmission network expansion in the area of the US electric system known as PJM. The applied mechanism combines the merchant and regulatory approaches to attract investment into transmission grids. It is...

The paper studies the characteristics of the evolution over time of modal split for a transport system in which various modes compete with each other and face the freight flow increase in different ways. It is shown that the modal split evolution is constituted by a sequence of time periods, in...

In many sectors of the economy, governments either provide various services at no cost or at highly subsidized prices. Examples are the health, education and general government sectors. The System of National Accounts 1993 recommends valuing these nonmarket outputs at their costs of production...

A repeated, discrete time, nonlinear Cournot duopoly game with adjusting heterogeneous players, i.e. bounded rational and adaptive, is subject of investigation. The game is modeled by a system of two nonlinear difference equations. The evolution of outputs over time is obtained by iteration of a...
