Although most production activities involve multiple outputs, econometric models of production or cost functions normally involve only one single homogeneous output. The aim of this paper is to test the hypothesis that a multiproduct specification is superior to a model with a single homogenous...

The purpose of the article is to discuss the operations of the public bus sector and the impacts of its privatization in Tirana, the capital of Albania. In addition to a synopsis of public transport operations in post-communist East Europe, the first part of this article presents an overview of...

This paper examines the cost structure particularly cost elasticities, returns to scale, marginal cost of production, technological progress, demand for factor of production, and factor substitution in publicly owned State Transport Undertakings (STUs) in India. To examine these issues, a...

A number of static and dynamic specifications of a log linear demand function for public transport are estimated using aggregate panel data for 22 Indian states over the period 1990 to 2001. Demand has been defined as total passenger kilometers to capture actual market transactions, while the...

In this paper we present an efficiency analysis of bus transport companies in Germany. It is focused on the calculation of scale efficiencies in order to identify possible economies of sca-le in the German bus transport market. For this purpose, we apply data envelopment analy-sis (DEA). As DEA...

Using a unique data set on German child care centers, we estimate a long-run multi-product cost function for child care provision in Germanywhile taking into account legal minimal labor input restrictions. For a representative child care center we find economies of scale, a U-shaped average cost...

Mobile communications markets worldwide, today, are saturated, the number of mobile network operators (MNOs) in market is declining, mobile revenues are stagnant or falling, MNOs are becoming wireless Internet service providers, and economies of scope are strengthening. This paper challenges...

In order to abate pollution, manufacturing facilities can either change their production processes (CPP) or introduce end-of-pipe technologies (EOP). The decision to undertake CPP rather than EOP is a reflection of the existence of economies of scope between production of the facility’s...

The purpose of this paper is to provide a simple model to explain buyer–supplier relationships and identify factors that determine the chosen number of trading partners. We show that the optimal number of partners for a supplier is small, if it has low bargaining power, moderate economies of...

This paper explores the impact of the implementation of modular platforms, to replace the standard platforms used to date, on the strategic outputs of automobile manufacturing networks. Analysis of the production network of manufacturers in Europe shows that the use of modular architecture...
