Understanding travel expenditure by means of market segmentation

Consolidated tourism destinations should expand their market share by focusing on tourism spending instead of number of travellers. This strategy emphasises satisfying the preferences and needs of tourists more dynamically in terms of their expenditure patterns. The purpose of this paper consists of evaluating the usefulness of an expenditure-based segmentation as a relevant instrument of tourism policy in order to increase the economic benefits from travellers to Andalusia. More specifically, by means of decision trees and linear regression statistical techniques, heavy spenders are identified as well as exploring which variables might be considered as the best predictors of travel expenditure. Finally, the implications of the results are discussed, as they may provide practical guidance for tourism practitioners at similar destinations.     

Economics of tourist's consumption behaviour: Some evidence from Australia

This study analyses the consumption behaviour of international tourists from Australia's four major source markets: New Zealand, UK, USA and Japan. A preliminary analysis of their consumption expenditures reveals intriguing similarities as well as diversities in consumption patterns. These are sought to understand in terms of the utility-maximising framework in which observed differences in prices and incomes play a key role. Based on the neoclassical economic theory of consumer behaviour, models incorporating five major components of tourist consumption – Accommodation, Food, Transport, Shopping and Entertainment- are estimated. Overall, the level of tourist consumption is found to be highly sensitive to incomes but less sensitive to prices. The low price sensitivity suggests tourists perceive the commodities as necessities and may also reflect their captivity at the destination, masking the underlying true price sensitivities. An important dimension underlying these findings is the possible lack of information about the destination leading to sub-optimal consumption choices.     

客专大站到发线运用随机机会约束模型与算法研究

在考虑到发线运用过程中不确定性因素的基础上，研究旅客列车停站时间和接续时间随机变动情况下客专大站到发线运用优化问题，以提高车站作业效率和方便旅客乘降为优化目标，建立了到发线运用的随机机会约束规划模型。通过将模型中的随机机会约束转化为相应的确定性等价形式，从而将随机规划模型转化为确定性模型，并设计了解决该问题的蚁群算法。算例表明该随机机会约束规划模型能取得可靠性更高的到发线运用计划。     

CONSUMPTION (IN)EFFICIENCY AND FINANCIAL ACCOUNT MANAGEMENT

Consumption may be inefficient when a household cannot choose the optimal bundle of goods at a minimum cost. After discussing alternative approaches, this paper proposes the use of money metric indirect utility function motivated by Feenstra and Varian in measuring consumption inefficiency. Then, Bamoul–Tobin transactions demand for money model is extended to show how household ability to manage its income, expenditure and financial accounts may affect consumption inefficiency. Results of the stochastic cost frontier approach, which is employed in estimation and the prediction of the European Union household consumption inefficiency, suggest that household expenditure performance is partly explained by the changes in the consumption efficiency and the efficiency is not independent of financial account management.
