An examination of the effect of messages on cooperation under double-blind and single-blind payoff procedures

Previous research has suggested that communication and especially promises increase cooperation in laboratory experiments. This has been taken as evidence for internal motivations such as guilt aversion or preference for promise keeping. The goal of this paper was to examine messages under a double-blind payoff procedure to test the alternative explanation that promise keeping is due to external influence and reputational concerns. Employing a 2×2 design, we find no evidence that communication increases the overall level of cooperation in our experiments with double-blind payoff procedures. However, we also find no evidence that communication impacts cooperation in our experiments with single-blind payoff procedures. Further, the payoff procedure does not appear to impact aggregate cooperation.     

Research to Estimate and Manage Carrying Capacity of a Tourist Attraction: A Study of Alcatraz Island

Carrying capacity has been a long-standing issue in management of parks, outdoor recreation and tourism. Contemporary carrying capacity frameworks rely on formulation of indicators and standards of quality to define and manage carrying capacity. This paper describes a programme of research to support estimation and management of carrying capacity of Alcatraz Island, an historic site within Golden Gate National Recreation Area, California, USA, and a heavily visited tourist attraction. Research included: (1) a survey of visitors to Alcatraz Island to identify indicators and standards of quality for the visitor experience; and (2) development of a computer simulation model of visitor use to estimate maximum daily use levels without violating standards of quality. Study findings are used to estimate a range of carrying capacities for the prison cellhouse and for the island as a whole.     

Developing a Surf Resource Sustainability Index as a Global Model for Surf Beach Conservation and Tourism Research

The growth of surfing activities and surf tourism has gained significant attention in the academia during the past decade. This paper is aimed at developing a framework of indicators and methods used in assessing the sustainability factors of surf sites. The research puts forward a Surf Resource Sustainability Index (SRSI) as a conceptual model to study the sustainability of surf tourism sites. The literature review, previous experience, and discussion with veteran surfers and scholars were used to develop indicators and determine their measurability and aptitude. Index pilot testing was carried out in Phuket, Thailand, where an emerging surf culture and tourism market segment add to the island's bustling economy and coastal resource-management issues. The case study underpins the importance of social, economic, environmental, and governance factors in the conservation process. The SRSI metrics provide a direct method for assessing surf sites and offer tangible benefits to surfers and other stakeholders.     

Consumer Rights: An Assessment of Justice

For the last 50 years the idea of consumer rights has formed an essential element in the formulation of policy to guide the workings of the marketplace. The extent and coverage of these rights has evolved and changed over time, yet there has been no comprehensive analysis as to the purpose and scope of consumer rights. In moral and ethical philosophy, rights are integrally linked to the notion of justice. By reassessing consumer rights through a justice-based framework, a number of key issues emerge regarding the way in which markets enable justice for consumers. The consumer rights which underpin the United Nations consumer protection guidelines address all forms of justice to some degree, but the predominant focus is on procedural justice. Our conclusions question whether this is sufficient and also whether there is a case to develop the notion of consumer ‘duties’ that complement the idea of rights.     

The Welfare Impact of Self-supplied Water Pricing in Canada: A Computable General Equilibrium Assessment

This paper uses a computable general equilibrium model to assess the welfare cost of changing the method of water allocation in Canada towards one that uses prices to ration demand. We model the introduction of a price on both water that is abstracted as well as water that is consumed (that is abstracted, and not returned to the source). We estimate that reducing water consumption by 25 % would require imposition of a price on water consumption of around $$\$0.21/\text{ m }^{3}$$ . Similarly, introduction of a water abstraction charge of about $$\$0.013/\text{ m }^{3}$$ would be sufficient to reduce water abstraction by 25 %. We find that if revenues from water pricing are returned in lump sum to households, the introduction of water pricing would result in a modest welfare loss. When revenues from water pricing are used to offset existing taxes, we find a gain in welfare corresponding to a ‘strong double dividend.’     

Frequency domain and time series properties of asymmetric error correction terms

The now familiar error correction model has recently been extended to allow for the modelling of asymmetric behaviour, resulting in the development of the asymmetric error correction model. Previous workers have undertaken studies upon which the ‘classic’, implicitly symmetric, error correction model was developed. It was found that the Escribo-Pfann method approach detected significant asymmetries while the Granger-Lee did not. In this paper the properties of the alternative methods are analysed in detail to examine why one method met with success, but not the other. Via the use of estimated sample spectral densities and correlograms, a significant property of the Granger-Lee method is uncovered. This property, particularly relevant in application to consumers' expenditure, has a wider relevance, helping explain why the approach has met with limited success.     

A censored system of cigarette and alcohol consumption

Many previous studies of US cigarette and alcohol consumption have focused on single equations. However, the addictive nature of consumption suggests that it is more appropriate to model these products as a system. We propose a two-step estimation procedure and apply the procedure to a system of equations for cigarette, beer and wine consumption. Results differ from those derived from an existing two-step procedure. Findings suggest that consumption of cigarettes, beer and wine is responsive to income changes but the elasticities are rather small. Personal physiques, education, age, race, ethnicity, health, gender, employment status, and regions also play significant roles in consumption.     

Household demand for fats and oils: two-step estimation of a censored demand system

A censored system of household fat and oil demand equations is estimated with a two-step procedure, using cross-sectional data from the 1987–1988 US Nationwide Food Consumption Survey. Own price and total expenditure elasticities are close to unity and there is no evidence of gross substitutability. Compensated elasticities suggest net substitution among the products considered.     

Gender differences,physical activity and body weight

We investigate the effect of physical activity on bodyweight and the gender differences in such effects, following the copula approach to endogenous switching regression. Using data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS), we find differentiated effects of socio-demographic variables on exercise and on Body Mass Indexes (BMIs), and differentiated effects of exercise on BMI, between genders. Regular exercise, on average, decreases BMI by 1.78 for women and 1.01 for men. Food price away from home has negative effects on BMI of both men and women.     

Strategic Planning in an Accounting Department using Causal Maps and Cognitive Factions

Strategic planning can be a time-consuming task for academic departments. As such, an effective and efficient strategic planning approach is paramount. This paper presents a strategic planning approach using causal mapping to uncover the factors which faculty members believed would make their department (in the USA) more successful. The information gathered during the session was used as part of an AACSB accounting maintenance of accreditation process. The approach applied here elicits faculty involvement in ways which bring to the surface perspectives held by subgroups/factions of faculty. Additional perspectives are positive in a strategic planning context as they can contribute to devising strategies that might not have resulted by considering only majority views. Content analysis of the strategic plan suggests the range of views uncovered were integrated into the plan, including both the strategic factors and the relative importance of the factors.
