Recreational benefits from a marine protected area: A travel cost analysis of Lundy

Marine Protected Areas (MPAs) have been proposed in many countries as a means of conserving parts of the marine environment. In some cases, MPAs may also confer recreational benefits. In this paper, a travel cost model is used to estimate the non-market recreational benefits arising from the Lundy Island Marine Nature Reserve (MNR). The estimated mean consumer surplus for visiting Lundy was found to range from £359 to £574 per trip. The designation of No Take Zone (NTZ) has also contributed to higher consumer surplus values. This result provides a strong economic justification for the designation of MPAs for recreational as well as conservation purposes.     

Perceptions of Urban Parks as Havens and Contested Terrains by Mexican-Americans in Chicago Neighborhoods

The objectives of this study were to (1) identify the benefits of parks for Mexican-American urban residents and the roles they play in the dynamics of their communities and (2) explore issues related to their existence and utilization in Latino communities. Bedimo-Rung, Mowen, and Cohen's (2005) model of the Role of Parks in Public Health was employed as a conceptual framework in this study. Data were collected in the summer of 2007 with two focus groups with 26 Mexican-American residents from two predominantly minority Chicago communities. Benefits of urban parks for Mexican-American residents were classified into five categories—environmental, social, psychological health, physical health, and cultural. The study also identified many problems related to the existence and utilization of parks in Latino communities that detracted from the benefits Mexican-Americans could obtain from visiting parks. They included insufficient access to parks, poor maintenance of the existing parks, crime and safety issues, and interracial conflict and discrimination. A new framework was proposed to model the benefits of parks for minority urban residents and factors that affect utilization of parks in minority communities.     

From the Eyes of an Exhibitor

Abstract

Conferences and conventions often depend on event/convention planners to produce spectacular tradeshows to support their programs. A study which focused on exhibitor needs and the perceived benefits of participation was conducted during the winter of 1999 at an International Arts Convention in the eastern United States. Exhibitors' interests in convention participation fell into four primary areas: making contacts, gaining information, gaining visibility, and booking/selling a product or service. Understanding the areas of importance to exhibitors and the services/products that are necessary for them to achieve success can go a long way toward providing a meaningful experience and an avenue for communication for both convention exhibitors and planners.     

How shark conservation in the Maldives affects demand for dive tourism

Shark-diving tourism provides important economic benefits to the Maldives. We examine the link between shark conservation actions and economic returns from diving tourism. A combined travel cost and contingent behaviour approach is used to estimate the dive trip demand under different management scenarios. Our results show that increasing shark populations could increase dive-trip demand by 15%, raising dive tourists’ welfare by US$58 million annually. This could result in annual economic benefits for the dive-tourism industry of >US$6 million. Conversely, in scenarios where shark populations decline, where dive tourists observe illegal fishing, or if dive operators lack engagement in shark conservation, dive trip demand could decrease by up to 56%. This decline causes economic losses of more than US$24 million annually to the dive tourism industry. These results highlight the dependence of the shark-diving industry on the creation and enforcement of appropriate management regimes for shark conservation.     

Benefits of leisure in overcoming gender violence experiences: a case study

This article is based on a case study carried out at Casa Malva, a shelter for female victims of gender violence in Gijón, Asturias (Spain). The study explores the potential therapeutic value of leisure in the process of personal recovery for women living in sheltered accommodation, and the positive impact leisure may have in overcoming a traumatic life event. The study comprised 16 semi-structured interviews with female victims of gender violence and three discussion groups with shelter staff. The article examines the concept of leisure and the potential benefits of leisure activities as part of the Personal Recovery Project (PRP) run by Casa Malva. PRP is an innovative recovery initiative aimed at helping women to overcome situations of gender violence by focusing on areas of experience, such as family, employment and leisure.     

The perceived benefits of agritourism: The provider’s perspective

This study examines the perceived benefits of agritourism by examining the importance of this activity in accomplishing 16 goals of farmers receiving visitors for recreation on their farms. This study also examines several farm household and business attributes associated with the accomplishment of four goal dimensions driving agritourism development. Data were derived from a survey conducted among 164 agritourism farms in Missouri. Results showed that agritourism mostly serves to capture new farm customers, educate the public about agriculture and enhance the quality of life for the farm family, which represents both, economic and non-economic benefits. Organized by goal dimensions, findings showed that agritourism is perceived as most important for market related goals, suggesting that the economic role of agritourism should not only be measured in terms of increased profits but also as a marketing tool. Four significant regression models showed that several farm business and household attributes are associated to the perceived agritourism benefits within four goal dimensions, suggesting opportunities for tailored promotional messages and policy considerations for the entrepreneurial development of agritourism.

The Keynesian Multiplier Effect Reconsidered

In the standard Keynesian framework, government spending on useless public works has a larger multiplier effect than spending on government transfer payments does. In other words, spending on useless public works increases national income by more than an equivalent increase in government transfer payments would. Nevertheless, their effects on national benefit are identical. For both, the national benefit equals the direct benefit created by the spending. If there are two income classes, some transfers reduce both the national income and the national benefit. Some government purchases completely crowd out private consumption and reduce the national benefit.     

Benefits analysis of particulate matter control programs – a case study of Tokyo

The objective of this case study was to assess economic benefits of past environmental policies of particulate matter (PM) in Tokyo by comparing observed pre‐control PM levels in 1975 and post‐control levels in 1998. The point estimates of the numbers of additional cases of avoided premature mortality and morbidity due to PM pollution control were (1) 3900 long‐term deaths in adults aged 30 years and older (population 5?098?000), (2) 4700 cases of chronic bronchitis in adults aged 30 years and older, (3) 7800 cases of in‐patient cardiovascular disease in adults aged 65 and older (population 1?281?942), (4) 3100 cases of in‐patient pneumonia in adults aged 65 and older, (5) 2500 cases of in‐patient chronic obstructive pulmonary disease in adults aged 65 and older, (6) 390?000 asthma attacks in asthmatics (population 450?000), and (7) 4500 cases of acute bronchitis in children aged 8–12 (population 300?300) during a one‐year period. The point estimate of medical costs in adults and children plus the cost of lost wages was a purchasing power parity‐adjusted $38 billion USD. Overall these results appear more likely to be underestimates than overestimates due to several unquantified benefits. The calculations of avoided health and productivity impacts suggest that pollution control policies successfully prevented a large expense to the society in extra medical care and lost work time.
