Reputation,search cost,and airfares

As cost of search for consumers decreases with the spread of the internet; researchers question whether this trend will lead to lower price or higher product differentiation. This paper examines a sample of offered fares to see if an airline choosing not to distribute its tickets via a channel where competitors' offers are directly observable may attempt taking advantage of potential customers. We find this to be the case. Our study suggests that the US airline industry appears to be evolving toward more product differentiation in the internet age.     

Travel,roads, risks and volunteers

International volunteers often travel to destinations (low- and middle-income countries) that carry a greater chance of being involved in a road-related injury and a possible fatality. Within this cultural exchange, tourists move from safe roads and cars to those that are potentially unsafe. Is this all part of the adventure of volunteering or should the tourist industry take some responsibility? This paper highlights the intersection between tourism and road injury and fatality risks (as pedestrians or in vehicles) with special attention to the longer term volunteer traveller. Social science theory underpins some of the discussions around risk and travel. A brief consideration of the international road traffic death and injury crisis and the emergence of the recognition that this impacts upon tourist safety is explored as backdrop to discussions. Tourism relies upon the ability for people to travel in and around the countries they travel to, often taking on the local travel arrangements prevalent in their destination. These local travel arrangements enable leisure tourists to explore their destination and volunteer travellers to live and work as locals. Is it time to consider and further the research on road risks as a growing feature of tourism?     

US airport ownership,efficiency, and heterogeneity

All US commercial airports are in the public sector yet not all have the same ownership type. For medium and large hub US airports we use stochastic frontier analysis to analyze the efficiency differences for alternative airport ownership types. We find that while form of ownership may matter for cost efficiency, in general its effect is relatively small. Yet type of public sector ownership does have cost efficiency implications in certain environments. Further, when heterogeneity is not controlled, the results change substantially so that type of ownership matters much more which demonstrates the importance of controlling for cross section heterogeneity.     

Tourism and aesthetic design: enchantment,style, and commerce

In an era of intense global competition, companies are searching for ways to achieve competitive advantage. The development of visually attractive products and physical settings can aid in the creation of brand differentiation and influence the purchasing behaviour of consumers. Image and style are important within consumer culture, as can be observed in everything from automobiles and home furnishings to clothes and Internet sites. Design appears to have transformed an ever expanding range of goods and spaces into attractive and enchanting commodities and commercial environments. In this paper, it is argued that the appearance of hotels is increasingly characterized by a form of commodified enchantment, the product of an aestheticization process that aims to create novelty, surprise, and excitement. Aesthetic ennoblement has become a reflection of capitalism's drive to produce appealing and fashionable environments that turn pleasure and comfort into profit. In a world increasingly shaped by consumption and commerce, the place of aesthetics is more complex than mere decoration.     

Product, operation, and demand relationships between manufacturers and retailers

This paper presents a framework for identifying the most adequate distribution structure between manufacturing and retailers, considering different characteristics of product, operation, and demand. Based on the random generation of different scenarios, it is indicated the adequacy of direct, echeloned, and mixed distribution structures to a given set of demand uncertainty, lead time variability, holding costs, and transportation costs. Sensitivity analyses are also performed to address managerial issues, such as the mission of a Local DC and the convenience of lead time demand pooling. Findings suggest an increase of mixed distribution structures to the detriment of purely direct/echeloned ones.     

Bike-share rebalancing strategies,patterns, and purpose

We provide a first spatio-temporal exploration of bicycle sharing system (BSS) rebalancing patterns from data extracted for individual stations at a fine temporal scale and operator interviews. Analyzing rebalancing operations for nine BSS, we describe implications for operators, municipalities, and future optimization work. We find that stations adjacent to transit hubs receive disproportionate amounts of rebalancing relative to trips and that rebalancing is more often responding to morning and afternoon demand exceeding station dock capacities rather than longer term accumulations of bicycles. More importantly, we observe some operator’ rebalancing behaviors constrained between opposing goals of maximizing trips, profits, and service level agreements. Many BSS have no explicitly defined purpose, but existing rebalancing strategies can support or clash with the purpose or suggested benefits of a BSS.     

Disability,wages, and commuting in New York

In the U.S., substantial employment and wage gaps persist between workers with and without disabilities. A lack of accessible transportation is often cited as a barrier to employment in higher wage jobs for people with disabilities, but little is known about the intraurban commuting patterns of employed people with disabilities in relation to their wage earnings. Our study compares wages and commute times between workers with and without disabilities in the New York metropolitan region and identifies the intraurban zones where residents experience higher inequities in wage earnings and commute times. We obtained our data from the Public Use Microdata Sample (PUMS) of the American Community Survey (ACS) for the 2008–2012 time period. We used linear mixed-effects models and generated separate models with log hourly wage or one-way commute time as the dependent variable. We find significant differences in wages and commute times between workers with and without disabilities at the scale of the metropolitan region as well as by intraurban zone. At the metropolitan scale, disabled workers earn 16.6% less and commute one minute longer on average than non-disabled workers. High commute and wage inequalities converge in the center, where workers with disabilities are more likely to use public transit, earn 17.1% less, and travel nearly four minutes longer on average than workers without disabilities. These results suggest that transport options are less accessible and slower for disabled workers than they are for non-disabled workers. Our findings indicate a need for more accessible and quicker forms of transportation in the center along with an increased availability of centrally located and affordable housing to reduce the disability gap in wages and commute times. We also find that workers with disabilities generally seek higher wages in exchange for longer commute times, but the results differ by race/ethnicity and gender. Compared to white men, minority workers earn much less, and white and Hispanic women have significantly shorter commute times. Our findings offer new geographic insights on how having a disability can influence wage earnings and commute times for workers in different intraurban zones in the New York metropolitan region.     

Airport charges,economic growth,and cost recovery

This paper shows that “strict” financial break-even for airports may not be socially desirable. To maximize social welfare, airports should be allowed to take losses or make profits at different times while achieving break-even only in the long run. In particular, with economies growing over time, socially optimal pricing for a new airport can involve deficit in its early years and surplus in its later years. This result has practical policy implications for the newly-built or expanded airports especially in the Asia-Pacific region.     

The Gawk,The Glance,and The Gaze: Ocular Consumption and Polar Bear Tourism in Churchill,Manitoba, Canada

Photography is an integral component in the observation of fauna in protected areas (Russell, 1995; Shackley, 1998). The importance of photography to wildlife tourism should come as no surprise since the relationship between photography and tourism has been well documented (Albers & James, 1988; Chalfen, 1979; Neumann, 1992). Behavioural observations and interviews conducted with polar bear viewers visiting the Churchill Wildlife Management Area near Churchill, Manitoba revealed motivations closely resembling what some authors have termed as ocular consumption (Lee, 2001; Ryan et al., 1999). This paper examines the relation between photography, the wildlife tourist gaze, and ocular consumption, and applies these concepts to one particular field setting.     

Tourism,changing architectural styles,and the production of place in Itacaré, Bahia,Brazil

This article examines changing architecture in Itacaré, Brazil, as it transitions from a fishing village to an international tourist destination. Tourism, as an assemblage of practices and perspectives, recreates places in specific ways that structure social and environmental relationships. Through an examination of historical architectural styles, tourist architecture, and popular architecture in Itacaré, this article analyses the ways a tourist economy has physically and socially rebuilt the city. Socially, the changing architecture marks and creates differences between class, racial, and regional identities while also providing an idiom through which public conversations about these changing economic systems and demographics are articulated. At the same time, the expansion of the city has led to racial-, regional-, and class-based segregation. Environmentally, tourist architecture creates new relationships to nature through re-imagining Itacaré’s position in relation to other rural and urban places and a new emphasis on the aesthetic value of nature.     

Reviewing the DATAS of aviation research data: Diversity,availability, tractability,applicability, and sources

The field of aviation research is entering the era of big data. While data-driven advancements in aviation have clearly brought about applicable models and results with immediate implications, we argue that the influx of aviation data should be better characterized and documented to enable more efficient and standardized usage. To this end, we examine 200 well-cited research articles from sub-disciplines ranging from revenue management to air traffic control published on or after 2010 in order to analyze the diversity, availability, tractability, applicability, and sources (DATAS) of data utilized in aviation research. We find high levels of data diversity within aviation research, with 16 data categories ranging from air traffic flow management-type data to data from distributed sensors in line with the Internet-of-Things (IoT) paradigm. We identified a dominance of proprietary, non-public data in aviation research, with 68% of the 200 research articles utilizing solely proprietary data in deriving their results, and a further 8% utilizing a mixture of proprietary and publicly available data. The pervasiveness of proprietary data has implications on reproducibility and extending research results. We also highlight the increasing tractability of the data by surveying the computational power required to process the data sets, and present vignettes of applications and results that stem from these data-driven studies. Finally, we propose several recommendations regarding standardizing data source nomenclature as well as increasing the availability of and usage of publicly available data.     

Immigrant settlement patterns,transit accessibility,and transit use

Public transit is immensely important among recent immigrants for enabling daily travel and activity participation. The objectives of this study are to examine whether immigrants settle in areas of high or low transit accessibility and how this affects transit mode share. This is analyzed via a novel comparison of two gateway cities: Sydney, Australia and Toronto, Canada. We find that in both cities, recent immigrants have greater levels of public transit accessibility to jobs, on average, than the overall population, but the geography of immigrant settlement is more suburbanized and less clustered around commuter rail in Toronto than in Sydney. Using logistic regression models with spatial filters, we find significant positive relationships between immigrant settlement patterns and transit mode share for commuting trips, after controlling for transit accessibility and other socio-economic factors, indicating an increased reliance on public transit by recent immigrants. Importantly, via a sensitivity analysis, we find that these effects are greatest in peripheral suburbs and rural areas, indicating that recent immigrants in these areas have more risks of transport-related social exclusion due to reliance on insufficient transit service.     

Business travelers’ ticketing,refund, and exchange behavior

This study investigates when and why business travelers make changes to their airline itineraries. Results are based on tickets purchased over a 9-month period by employees of a university in Atlanta, US. The ability to track repeat passengers purchases across time allows analysis of how passenger cancellation behavior differs by frequency of travel as well as by carrier. Results indicate that frequent travelers and those purchasing from Delta versus AirTran are more likely to request ticketing changes. Other factors influencing cancellation behavior include the time from ticket purchase, time before flight departure, and whether the itinerary is for the outbound or inbound portion of a trip.     

Negotiation,bargaining, and discounts: generating WoM and local tourism development at the Tabriz bazaar,Iran

This paper examines the effects of negotiation intention, bargaining propensity, and discount satisfaction on word-of-mouth (WoM) behaviours for tourists visiting Tabriz bazaar, Iran. Data from 615-survey respondents highlight that tourists are motivated to conduct WoM behaviour when they are experientially satisfied with the opportunity to negotiate and bargain, and when they are satisfied with the discount they receive. This paper makes theoretical contributions to social exchange theory and presents managerial implications for policy-makers to generate tourism development.     

Emissions,performance, and design of UK passenger vehicles

Consumer, legal, and technological factors influence the design, performance, and emissions of light-duty vehicles (LDVs). This work examines how design choices made by manufacturers for the UK market result in emissions and performance of vehicles throughout the past decade (2001–2011). LDV fuel consumption, CO₂ emissions, and performance are compared across different combinations of air and fuel delivery system using vehicle performance metrics of power density and time to accelerate from rest to 100 km/h (62 mph, t_z-62). Increased adoption of direct injection and turbocharging technologies helped reduce spark ignition (SI, gasoline vehicles) and compression ignition (CI, diesel vehicles) fuel consumption by 22% and 19%, respectively, over the decade. These improvements were largely achieved by increasing compression ratios in SI vehicles (3.6%), turbocharging CI vehicles, and engine downsizing by 5.7–6.5% across all technologies. Simultaneously, vehicle performance improved, through increased engine power density resulting in greater acceleration. Across the decade, t_z-62 fell 9.4% and engine power density increased 17% for SI vehicles. For CI vehicles, t_z-62 fell 18% while engine power density rose 28%. Greater fuel consumption reductions could have been achieved if vehicle acceleration was maintained at 2001 levels, applying drive train improvements to improved fuel economy and reduced CO₂ emissions. Fuel consumption and CO₂ emissions declined at faster rates once the European emissions standards were introduced with SI CO₂ emissions improving by 3.4 g/km/year for 2001–2007 to 7.8 g/km/year thereafter. Similarly, CI LDVs declined by 2.0 g/km/year for 2001–2007 and 6.1 g/km/year after.     

Urban spatial structure,employment subcenters,and freight travel

Metropolitan areas in the U.S. have become increasingly polycentric. Large employment subcenters have emerged outside of central cities, competing against the traditional city center for labor and businesses. The existing literature on land use and transportation focuses on passenger travel, providing little insight into the impact of polycentric metropolitan development patterns on freight activity. In this study, we use the Los Angeles region as a case study to examine the relationship between urban spatial development patterns and freight travel. Using the National Employment Time Series (NETS) data, we identify employment subcenters in metropolitan Los Angeles. We characterize freight activities associated with the subcenters using data from the Southern California Association of Governments (SCAG). We develop a regression model that estimates freight activity as a function of geographic characteristics, such as whether a location is in an employment subcenter, measures of nearby employment, access to the highway network, and proximity to intermodal freight facilities. The results indicate that employment is an important driver of freight activity; however, employment subcenters have an independent effect on freight activity. The results of this study suggest that further research on urban spatial structure and freight activity should assess the effects of employment subcenters and how their particular employment composition and characteristics are associated with freight activities at the metropolitan level. Such an approach would lead to more precise policy recommendations for urban goods movement.
