چکیده
This note explores the extent to which airlines operating large hub-and-spoke networks secure a competitive advantage. More speci®cally, this paper explores the intricate relationship which arises among productive eciencies and pro®tability when the size of the hub-and-spoke network expands. To this end, Brueckner and Spiller (1991, International Journal of Industrial Organization 9, 323±342) airline economics model is generalized by allowing the size of the hub-and-spoke network to vary. The central result shows that, although the model exhibits decreasing returns to ®rm/network size (RTNS), nonetheless there is a competitive advantage to increasing the size of a network.

Due to the high mobility of the profession and complication of jurisdictions, there is no exact ®gure of the number of seamen worldwide. This paper establishes a method to estimate maritime labour worldwide as well as on open-registry ̄eets. ...

This paper uses the implications of Samuelson's spatial equilibrium model to analyze transportation rates for steam coal delivered to electric utilities in the United States. The analysis indicates that transportation rates declined in every year but two since railroads were substantially deregulated in 1980. While some utilities may have experienced some rate increases, coal-®red electric util...

In this paper, an exploratory study of failure and distress prediction models is presented based on a qualitative survey among new-entrant airline managers and a quantitative data source containing ®nancial and trac data of new-entrant airlines. Using logistic regression, it became evident that qualitative variables are a viable source for model construction. They contribute to a deeper unders...

This paper extends previous works that view transit systems as minimizing their after-subsidy costs. The paper uses the expense preference behavior model in economics and derives ®rst-order conditions for the manager. From the ®rst-order conditions, the paper formally shows that the decomposition of relative price ineciency between management behavior and subsidies found in the work of Sakano ...
