Highway traffic flow and the uneconomic region of production

In this paper highway traffic flow is formulated as a short-run production function in which traffic volume is the output and traffic density is the variable input. Given this formulation, the ‘uneconomic’ region of production is relevant. Often it is the case that traffic density will exceed the point at which traffic volume is at a maximum; i.e., the marginal product of the variable input is negative.     

Soil and Moisture Management in Mali: A Case Study Analysis for West Africa

In order for farmers to accept improved soil and water management practices, new technologies must be appropriate to the specific site conditions found in the farm setting and be consistent with farmers' objectives and available resources. A whole-farm modeling analysis of this problem is described. Preliminary estimates of the benefits of increased soil moisture conservation for representative low-resource farmers in Mali are presented. If farmers could improve rainfall infiltration from currently low rates of about 40% up to 60%, and use small amounts of chemical fertilizers, disposable income could increase two to four times depending on rainfall. Income could be increased another 50% if the infiltration rate was raised to 80%. Food grain production could increase 60 to 90% with improved moisture conservation and fertilizer use.     

The effect on the Italian private pension market of increased uncertainty concerning public pension provision

This paper examines the effect on the demand for private pensions in Italy of the recent strong increase in uncertainty concernin future public pension provision. Theory suggests that such increase uncertainty will increase the demand for all forms of private sector saving, and, in particular, the demand for private pensions — despite the present generosity of the Italian public pension arrangement. This theoretical proposition is confirmed by an empirical test. The implications are important.     

Sustainable tourism development and residents’ perceptions in World Heritage Site destinations

Set in Malaysia’s Lenggong Valley World Heritage Site (WHS), this paper uses stakeholder theory to explore the heterogeneity of positive and negative perceptions among residents and their effects on residents’ support for and participation in sustainable tourism development. Data from 221 completed questionnaire surveys revealed heterogeneous negative perceptions across residents’ age, level of education and economic involvement in tourism. Moreover, residents’ positive perceptions had a positive effect on their support for and participation in tourism development. This study contributes to the resident perception literature by using stakeholder theory to conceptualise the heterogeneity of residents’ perceptions and by examining the effects of those perceptions on their support for and participation in tourism development in a rural WHS destination in the developing world. Furthermore, the findings of this study have practical implications for local authorities aiming to improve residents’ support and participation in tourism planning for sustaining tourism development.     

Learning through engagement: undergraduate students engaging in community-based participatory research (CBPR) in hospitality and tourism education

This paper discusses how instructors can engage their students in community-based participatory research (CBPR) projects that involve not only research on a topic but also include community stakeholders in the research process and provide opportunities for service learning. CBPR is defined, examples of effective CBPR student projects are presented, the possible benefits and drawbacks of CBPR student projects are offered, and tips for conducting successful CBPR projects with hospitality and tourism students are provided.     

The politics,satisfaction, loyalty,and success of Ph.D. students in hospitality and tourism

The purpose of this study was to explore the roles of organizational politics in educational institutions with regard to graduate students’ satisfaction with supervision and loyalty toward advisors, and thereby success of students in the Ph.D. program, within the hospitality and tourism discipline. The findings demonstrate that satisfaction and loyalty play important roles in doctoral students’ experiences in graduate education. Several implications for students and faculty are discussed.     

Firm‐specific human capital investments as a signal of general value: Revisiting assumptions about human capital and how it is managed

Research summary : Prior scholarship has assumed that firm‐specific and general human capital can be analyzed separately. This article argues that, in some settings, this is not the case because prior firm‐specific human capital investments can be a market signal of an individual's willingness and ability to make such investments in the future. As such, the willingness and ability to make firm‐specific investments is a type of general human capital that links firm‐specific and general human capital in important ways. The article develops theory about these investments, market signals, and value appropriation. Then, the article examines implications for human resource management and several important questions in the field of strategic management, including theories of the firm and microfoundations of competitive advantage. Managerial summary : While managers don't often use the terms firm‐specific and general skills, they certainly recognize that investments employees make in their skill sets are more or less relevant to a specific firm. For instance, investing in specific relationships within a firm or learning a firm's proprietary software would be considered firm‐specific investments. While such skills may seem relevant only to the particular firm in which they were invested, these investments may also send valuable signals to competing firms that such employees are willing and able to make similar investments elsewhere. Hence, managers should be interested in determining if a potential hire has made prior firm‐specific investments to help them know whether that person might be likely to make such investments in his or her future place of employment.

Contesting authentic practice and ethical authority in adventure tourism

This paper examines the discourses of authenticity and ethics employed by adventure tourists regarding the use of the natural environment. In one case, full-time traveling rock climbers use their dedication to the sport and annual visits to the Red River Gorge as evidence for their authoritative voice on ethical climbing practice. While they identify the growing numbers of leisure climbers as a problem for sustainability, many also take up temporary employment as guides and are directly involved in the introduction of new climbers to the area. In another case, two groups of wilderness enthusiasts – “ADK 46ers” and “Summit Stewards” – lament the environmental and social impacts of other recreational users in the Adirondack Park. Despite being visitors themselves, Summit Stewards and 46ers use their sense of place and knowledge of Adirondack history and ecology to substantiate their authority as purveyors of ethical practice. In both cases, senses of responsibility are inspired by senses of place, but are articulated through notions of authenticity and used as justification for ethical authority. While validating their presence in these outdoor spaces, the use of such rhetoric also minimizes their own impacts yielding further tensions among user groups.     

Why Mortgage Borrowers Persevere: An Explanation of First and Second Lien Performance Mismatch

Borrowers with a pair of mortgages collateralized by the same property sometimes continue to make payments on one while defaulting on the other. We articulate a framework for understanding this performance mismatch that emphasizes two types of borrowers: those with stable equity positions who perceive they are facing moderate or temporary liquidity shocks, and those facing severe financial stress in combination with negative equity. The former have an incentive to enter mismatch and subsequently cure, while the latter would default on both contracts. Our empirical analysis using newly available, national samples of matched first‐ and second‐lien mortgages supports this view.     

<Emphasis Type="Italic">GTE Sylvania</Emphasis> and Interbrand Competition as the Primary Concern of Antitrust Law

Footnote 19 of the landmark U.S. antitrust decision in Continental T.V. v. GTE Sylvania, Inc. 433 U.S. 36 (1977) declares that “Interbrand competition … is the primary concern of antitrust law.” We trace the antecedents and influence of this declaration, argue that it is inappropriate, and conclude that it should be abandoned.
