The  Price Elasticity of Demand for Air Travel.  Some New Evidence
September 1976, Vol. 10, No. 3, Page 257.
J.M. Jung  E.T. Fuji      
The authors find that demand for air travel is price elastic for distances under 500 miles in east and south USA.  Some carriers have increased profits by reducing fares.

A Coherence Approach to Estimates of Price Elasticities in the Vacation Travel Market
January 1980, Vol. 14, No. 1, Page 19.
J.H.E. Taplin         
This paper examines five sectors of the vacation travel market and estimates cross-elasticities within the range of feasible values.

Transit Service Elasticities.  Evidence from Demonstrations and Demand Models
May 1981, Vol. 15, No. 2, Page 99.
A.M. Lago  P. Mayworm  J.M. McEnroe   
There is little elasticity of demand for improvements in transit service, especially where service is already good.  Headways are more important than in-vehicle time.  Information is lacking on reliability, availability of seats, and transfers.

Inferring Ordinary Elasticities from Choice or Mode-Split Elasticities
January 1982, Vol. 16, No. 1, Page 55.
J.H.E. Taplin         
It may be possible to infer ordinary from mode-choice elasticities on the basis of second stage elasticities derived from one ordinary elasticity estimate.  Failing that, the range of feasible values may be narrowed by constraints.

Some Characteristics of Rail Commuter Demand
May 1983, Vol. 17, No. 2, Page 115.
S. Glaister         
The results of this study suggest that annual season tickets are too cheap and that cheap day tickets are too dear.  Small changes in service frequency had no noticeable effect.

Elasticity Measures and Disaggregate Choice Models
May 1984, Vol. 18, No. 2, Page 189.
J.P. Dunne         
There are dangers in the use of some measures, but an approximate arc elasticity performs well.

An Almost Ideal Demand System for Visitor Expenditures
May 1985, Vol. 19, No. 2, Page 161.
E.T. Fujii  M. Khaled  J. Mak   
The authors analyse expenditure by visitors to Hawaii on six categories of goods, and estimate own and cross price elasticities of demand.

Alternative Demand Models and their Elasticity Estimates
May 1989, Vol. 23, No. 2, Page 163.
T.H. Oum         
Choice of functional form for the demand (forecasting) model is very important for empirical research.  Of the five models examined, the translog demand system with theoretical constraints imposed upon the parameters performs the best.  But further investigation is needed.

Public Transport Demand Elasticities in Spain
May 1990, Vol. 24, No. 2, Page 189.
G. de Rus         
From his study of elasticities the author concludes that patronage of public transport in Spanish cities could be increased by adjustment of the proportionate charges for cash fares and multiple-ride tickets, and by increasing fares to provide higher frequencies.

The Demand for Travel and for Travelcards on London Regional Transport
January 1991, Vol. 25, No. 1, Page 3.
C.L. Gilbert  H. Jalilian      
The authors develop a joint model for the demand for travel and the demand for travelcards.  The estimates are that demand for underground travel is inelastic while the demand for bus travel is elastic.  Simulation analysis attributes between one third and one half of the rise in demand for underground travel in the period 1982-87 to employment growth; and between one half and two thirds to the introduction of travelcards.

Concepts of Price Elasticities of Transport Demand and Recent Empirical Estimates
May 1992, Vol. 26, No. 2, Page 139.
T.H. Oum  W.G., Jr. Waters  J.-S. Yong   
The authors consider various concepts of demand elasticities, and several improvements in the methodology of transport demand studies are described.  They also summarise the results for over sixty recent studies, and identify a number of problems along with suggested priorities for future research.

A Review of New Demand Elasticities with Special Reference to Short and Long Run Effects of Price Changes
May 1992, Vol. 26, No. 2, Page 155.
P.B. Goodwin         
A literature review suggests that increases in real fuel prices would lead to a short run reduction in both traffic and consumption, due to more careful driving and differential responses for different journeys.  In the longer run the effects would be increased.  It is suggested that non-dynamic estimation methods are biased, and that transport prices have wider effects, and are a more important lever of transport policy, than has sometimes been assumed.

Inter-Firm Rivalry and Firm-Specific Price Elasticities in Deregulated Airline Markets
May 1993, Vol. 27, No. 2, Page 171.
T.H. Oum  A. Zhang  Y. Zhang   
This paper examines the pattern of a firm's pricing rivalry and its associated price elasticities in a set of duopoly routes.  The parameters of the marginal cost function are also estimated.  This model allows for free variation of estimated "conduct parameters" and price elasticities across airline routes.

The Role of Wealth in Demand for International Air Travel
May 1994, Vol. 28, No. 2, Page 163.
G. Alperovich  Y. Machnes      
The authors formulate and estimate a model of international air travel demand for Israel.  Consumers' wealth is found to be a significant determinant and failure to include it in the estimated equations yields price elasticities which are biased downward and income elasticities which are biased upward.
