This paper analyses the cost structure of a sample of Italian Local Public Transport (LPT) companies operating in large urban centers and metropolitan areas, with the aim to extend the evidence of some recent studies focused only on small and medium-sized operators. Technological characteristics...

We analyze a simple oligopoly model where firms can engage in cost-reducing R&D. We compare two R&D regimes, that is, R&D competition and R&D cooperation where firms can enter in a Research Joint Venture (RJV). We introduce coordination costs for the RJV and examine how these affect the...

Статья посвящена анализу перехода от экономики централизованного планирования к рыночным отношениям, выявлению проблем и разработке необходимых...

The article presents different approaches of a number of authors how to determine the optimal size of agricultural organizations and their nature. There are different methods that were used while searching, including statistical, monographic, constructive and others. The article also presents...

This paper studies the cost structure of Swiss gas distribution utilities. Several econometric models are applied to a panel of 26 companies over 1996–2000. Our main objective is to estimate the optimal size and scale economies of the industry and to study their possible variation with respect...

The high penetration of distributed generation (DG) is a new challenge for traditional distribution systems. Power injections from DG units change network power flows, thereby influencing system losses and voltage stability. This paper presents a new multiobjective index (IMO)-based analytical...

Size optimization of solar array and battery in a standalone photovoltaic (SPV) system is investigated. Based on the energy efficiency model, the loss of power supply probability (LPSP) of the SPV system is calculated for different size combinations of solar array and battery. For the desired...

The penetration of renewable sources into the grid, particularly wind and solar, have been increasing in recent years. As a consequence, there have been serious concerns over reliable and safety operation of power systems. One possible solution, to improve grid stability, is to integrate energy...
