Airline networks as joint goods: Implications for competition policy

This article derives a model of airline services as joint goods. Using this model, the article shows how the existence of higher fares in certain hub routes may imply the market has generated a solution to the problem of covering joint costs by having a larger proportion of those costs come from hub routes, rather than the existence of any general market failure. The model is then used to make recommendations for competition policy.     

Testing Alternative Hypotheses in Economic History

This paper employs a statistical technique comparing non-nested quantitative models in order to address an important problem in economic history, namely, the appropriate role of microeconomic models in historical analysis. Discussion proceeds by example. As described in the paper, three research groups have offered explantations of the shift from corn to cotton production in the post-bellum US South but because their research methods are different, it is difficult to evaluate them effectively. This paper suggests a method for comparing them. The method is based on the Neyman–Pearson likelihood ratio and proceeds by focusing on the three groups’ models of crop choice, in turn hypothesizing each model as ‘truth’, and testing all other against it. Though restrictive in its own right, this excercise suggests one data-oriented approach to all-too-common problem of model proliferation in economic history.     

A MODEL OF NEW ZEALAND APPLE SUPPLY RESPONSE TO TECHNOLOGICAL CHANGE*

A supply response model for New Zealand apples is specified and equations for new plantings, removals, yields and adoption of an innovation are estimated. The model expands on perennial crop models previously estimated by incorporating the time pattern of adoption of a planting innovation and formulation of a measure of yield expectations given technological change.
