A PRIMER ON MATHEMATICAL MODELLING IN ECONOMICS

Abstract The Commission on Graduate Education in Economics had raised several concerns regarding the role of mathematics in graduate training in economics ( Krueger, 1991 ; Colander, 1998, 2005 ). This paper undertakes a detailed scrutiny of the notion of a utility function to motivate and describe the common patterns across mathematical concepts and results that are used by economists. In the process one arrives at a classification of mathematical terms which is used to state mathematical results in economics. The usefulness of the classification scheme is illustrated with the help of a discussion of Arrow's impossibility theorem. Common knowledge of the patterns in mathematical concepts and results could be effective in enhancing communication between students, teachers and researchers specializing in different sub‐fields of economics.     

Residents’ perspectives of a newly developed ecotourism project: an assessment of effectiveness through the lens of an importance–performance analysis

Understanding the perceived importance and performance of various components of ecotourism to residents living in the area it is undertaken is crucial to the overall success of an ecotourism development project. This study examines residents’ perceptions of the importance and performance of ecotourism components (i.e. environmental conservation, economic wellbeing, promotion of local arts and culture, local participation, and fair share of resources), including overall ecotourism development, at the Gaurishankar Conservation Area (GCA) – a recently implemented ecotourism development project in Nepal. This study also examines the effect of socio-demographic, economic, and psychological factors on a perceived gap between the importance and the performance of ecotourism components. Findings suggest that the ecotourism development project at the GCA should concentrate on improving the economic wellbeing of residents, and on overall ecotourism development. Findings also suggest that residents’ inclusion in benefit-sharing mechanisms was associated with a reduced perceived gap between the importance and performance of ecotourism components. A comparison among different geographical segments of residents indicated that the perceived gap between importance and performance varies across different locations.     

Cost-System Choice and Incentives—Traditional vs. Activity-Based Costing

We incorporate information and managerial incentives into the analysis of a common cost-management tool—activity-based costing (ABC). We study the choice of a costing system in a firm where the owners contract with a manager to use either a traditional or an ABC system and make production decisions. We show that, as commonly argued in managerial-accounting literature, in a first-best setting with no informational asymmetries the ABC system is always preferred to the traditional costing one. However, when the firm's manager has relevant private information, the owners' choice of a costing system is not as clear. We demonstrate that the firm earns higher expected profits under the ABC system when the uncertainty about the manager's private information is high. Conversely, the firm's expected profit is higher under the traditional costing system when the uncertainty surrounding the manager's private information is low because the gross benefits of better information provided by ABC are exceeded by the additional informational rents the owners must pay the manager under this system. Our results provide a formal explanation of the coexistence of traditional and ABC systems in practice.     

Generalized contest success functions

The key element of models of contest is the contest success function (CSF) which specifies the winning probabilities of agents. The existing axiomatizations of CSFs assume that contestants can make only one type of investment. This paper generalizes these axiomatizations to the case where each agent can have multiple types of investments. This allows us to provide a unified framework to extend and interpret the results of Skaperdas (Econ Theory 7:283–290, 1996) and Clark and Riis (Econ Theory 11:201–204, 1998), and rationalize some seemingly ad hoc CSFs used by applied researchers. This paper has benefitted from the comments of Aicke Hinrichs, Rene Levinsky, and two anonymous referees. We are especially thankful to one of the referees for detailed comments which have helped improve every aspect of this paper.     

Enhancing Park and Ride with access control: A case study of Southampton

Implementing and promoting more sustainable forms of urban transport are key policies of Local Authorities throughout the UK. Park and Ride (P&R) is one such system implemented widely in the UK, especially in historic towns and cities with limited road and parking space in the centre. Some cities (e.g. Rome and London) have also implemented forms of ‘access control’ to reduce congestion and/or pollution in central areas. This paper describes a feasibility analysis of a unique application studied for potential implementation in Southampton—the integration of P&R with access control on a key corridor in Eastern Southampton where traffic demand is likely to increase significantly in the coming years because of new housing developments. The system concept is a P&R facility with express buses to the City centre, keeping the corridor free-flowing for these buses (and other traffic) using a combination of bus lanes and access control.Following an outline of the policy context and system design, this paper then describes the corridor and network modelling undertaken to predict the impacts of the scheme and alternatives of it. This has been based mainly on the CONTRAM dynamic traffic assignment model, which covers the whole of Southampton and its surrounding motorway network. The assessment of the benefits of the various options in this scheme showed that the combination of P&R with signalised access control was the best option to improve the movement of people on the corridor. The paper concludes with a discussion of potential issues for implementation, including the need for complimentary measures and a consistent policy framework.     

Auctions for transferable objects: Theory and evidence from the vehicle quota system in Singapore

This paper studies the hypothesis that auctions with resale markets result in higher prices. The vehicle quota system introduced in Singapore in May 1990 provides the setting. The Certificates of Entitlement (COEs) necessary to purchase new cars were initially transferable for all quota categories. After October 1991, COEs for four major categories became non-transferable. Our results indicate that while the conversion to non-transferability eliminated speculation, it has also intensified competition among car distributors. Auctions for non-transferable COEs in fact led to higher COE prices in three of the four categories.An earlier version of this paper was presented at the Symposium on Law and the Social Sciences, 7 August 1992, at the Regional English Language Centre, Singapore. We want to thank our colleagues for discussions on the subject, the Chief Editor and two anonymous referees of the journal for their constructive comments and suggestions, and the Registry of Vehicles of Singapore for providing us with the data for this study.

Intraday volatility in the stock index and stock index futures markets

We examine the intraday relationship between returns and returnsvolatility in the stock index and stock index futures markets.Our results indicate a strong intermarket dependence in thevolatility of the case and futures returns. Price innovationsthat originate in either the stock or futures markets can predictthe future volatility in the other market. We show that thisrelationship persists even during periods in which the dependencein the returns themselves appears to weaken. The findings arerobust to controlling for potential market frictions such asasynchronous trading in the stock index. Our results have implicationsfor understanding the pattern of information flows between thetwo markets.

The performance of Japanese mutual funds

We analyze the performance of Japanese open-type stock mutualfunds for the 1981-1992 period. The results show that, regardlessof the performance measures and benchmarks employed, most ofthe Japanese mutual funds underperform the benchmarks by between3.6% and 10.8% per annum. These funds tend to invest more inlarge stocks with low book-to-market ratios. But this featuredoes not explain the underperformance. A potential explanationis the dilution effect caused by inflows of funds. In Japan,a new investor of an open-type fund only pays in the after-taxvalue of the net asset value. We conduct a bootstrap experimentto assess the magnitude of this dilution effect.
