Backpackers in the Northern Territory of Australia—motives,behaviours and satisfactions

This paper reports the findings of a study of 475 backpackers in the Northern Territory of Australia. It finds that backpackers tend to visit many of the same locations as other tourists, and like those tourists, are attracted to the natural sights of the Territory. It is also found that the backpackers can be divided into various groups. For example, of this sample about one‐third had left their previous career to travel, and about 12% had just completed studies. On the other hand about one‐quarter were holidaying during periods of normal paid holiday leave. It is argued that the market is not solely comprised of ‘life change’ or rite de passage holidaymakers. Additionally, differences are found between national groupings.

Fuel economy gaps within and across garages: A bivariate random parameters seemingly unrelated regression approach

The key objective of this study is to investigate the interrelationship between fuel economy gaps and to quantify the differential effects of several factors on fuel economy gaps of vehicles operated by the same garage. By using a unique fuel economy database (fueleconomy.gov), users’ self-reported fuel economy estimates and government’s fuel economy ratings are analyzed for more than 7000 garages across the United States. The empirical analysis, nonetheless, is complicated owing to the presence of important methodological concerns including potential interrelationship between vehicles within the same garage and unobserved heterogeneity. To address these concerns, bivariate seemingly unrelated fixed and random parameter models are presented. With government’s test cycle ratings tending to over-estimate the actual on-road fuel economy, a significant variation is observed in the fuel economy gaps for the two vehicles across garages. A wide variety of factors such as driving style, fuel economy calculation method, and several vehicle-specific characteristics are considered. Drivers who drive for maximum gas mileage or drives with the traffic flow have greater on-road fuel economy relative to the government’s ratings. Contrarily, volatile drivers have smaller on-road fuel economy relative to the official ratings. Compared to the previous findings, our analysis suggests that the relationship between fuel type and fuel economy gaps is complex and not unidirectional. Regarding several vehicle and manufacturer related variables, the effects do not just significantly vary in magnitude but also in the direction, underscoring the importance of accounting for within-garage correlation and unobserved heterogeneity for making reliable inferences.     

Industry influence on firms' R&D and innovation

This paper examines the effect of peers on a firm's research and development (R&D) policy. We show that firms do not make R&D decisions in isolation, and that industry dynamics play an important role in defining a firm's R&D intensity. Using a large sample of 54,393 firm-year observations from 1991 to 2015 in the United States, we find that firms' R&D decisions are mainly driven by their industry peers' R&D policies. Moreover, we find that R&D mimicking is significant only in the presence of strong product market competition, whereas we do not find any evidence of information-based herding in R&D investments. Our additional analysis shows that our main conclusions remain valid even in the presence of financial constraints, and regardless of the firms' market positions. Finally, we provide evidence that R&D mimicking increases firms' future values, future patent outputs, and estimated patent dollar values. Our findings are robust to endogeneity concerns, and to using alternative sample compositions, R&D intensity proxies, and different industry classifications.     

Islam’s Gift: An Economy of Spiritual Development

According to the standard narrative, economics is an objective and scientific study of universal laws applicable to economic affairs of modern societies. After a brief introduction, the second section of the article presents a counter‐narrative that disputes this claim, and provides an alternative point of view that situates modern economics within its European historical, political, and social context. We briefly discuss why the conventional methodology of modern economics makes false claims to objectivity and universality. The third section provides an alternative methodology that is based on the recognition that human behavior is inherently and unavoidably normative, and any study of human beings and societies must take this into account. The fourth section of the article brings out the norms concealed within the foundations of modern economics, since the avowed methodology does not permit explicit and open expression of these norms. The fifth section describes Islamic views that describe the normative ideals for our personal and social lives. In particular, Islam aims at the development of the potential for excellence that every human being is born with. It does not aim at accumulation of wealth and material possessions. Nor does it aim at achievement of happiness through the maximization of pleasure achieved by consumption. The sixth section describes the transformational strategies required for spiritual progress in different dimensions of our human existence. The seventh section describes some of the institutional structures required in the economic realm to assist in the achievement of the transformation towards the normative ideals. The final section explains how we should use our unique and precious lives to aim for higher goals than mere consumption of goods and acquisition of wealth.     

Managing heritage tourism in Toraja: strengthening local values and improving tourists’ experiences

Toraja, South Sulawesi, Indonesia, is a tourist destination known best for its ethnicity and was one of the main tourist destinations in Indonesia during the 1990s. Since 2011, the government has again designated Toraja a priority strategic tourism area in its national tourism development plan. This case study describes opportunities for, and issues associated with, heritage tourism in Toraja and explores community perspectives on tourism. The fieldwork data and secondary data were used in preparing the detailed plan for the National Tourism Strategic Area of Toraja (KSPN Toraja). The opportunities for heritage tourism in Toraja include, among others, an emerging Asian market, better transport access to the region, and central government resources and programs to complement those of the local government. The core issues of local community concern include the need to conserve Torajan heritage and to strengthen local values; develop and nurture culture alongside tourism; balance heritage conservation with tourism; and the need for better interpretation to convey local wisdom to enhance the visitor experience.     

A comparative study of driving performance in metropolitan regions using large-scale vehicle trajectory data: Implications for sustainable cities

Volatile driving, characterized by hard accelerations and braking, can contribute substantially to higher energy consumption, tailpipe emissions, and crash risks. Drivers’ decisions to maintain speed, accelerate, brake rapidly, or jerk their vehicle are largely constrained by their unique regional and metropolitan contexts. These contexts may be characterized by their geography, roadway structure, traffic management, driving population, etc. This study captures how people generally drive in a region using large-scale vehicle trajectory data, implying how energy is consumed and how emissions are produced in regional transportation systems. Specifically, driving performance in four U.S. metropolitan areas (Los Angeles, San Francisco, Sacramento, and Atlanta) is compared, taking advantage of large-scale behavioral data (78.7 million seconds of speed records), collected by in-vehicle global positioning systems (GPSs) as part of regional surveys. Comparative analysis shows significant regional differences in terms of volatile driving and time spent to accelerate, brake, and jerk the vehicle during daily trips. Correlates of higher volatility are also explored, e.g., battery electric vehicles show low volatility, as expected. This study proposes a novel way to compare regional driving performance by successfully turning GPS driving data into valuable knowledge that can be applied in practice by developing regional driving performance indices. The new indices can also be used to compare regional performance over time and to imply the levels of sustainability of regional transportation systems. This study contributes by proposing a way to extract useful information from large-scale driving data.     

Failures of the “Invisible Hand”

Despite many failures of the invisible hand both empirically and theoretically, it continues to be vigorously asserted and widely believed. We document the failures and explain why it continues to be asserted despite these failures.     

Heritage Tourism in Rural Areas: Challenges for Improving Socio-economic Impacts

Many developing countries seek to utilize cultural heritage sites as resources for socio-economic development through heritage tourism. When rural area is the context of heritage tourism, effort is needed to establish linkages between tourism and the local economy by addressing the following issues: lack of skilled human resources, capital, access to credits, and other assistance; leakages; and dominance of urban players. This paper examines the impacts of heritage tourism on rural livelihoods using Borobudur in Central Java, Indonesia, as the case study. Further, it proposes rural industry promotion as one of the ways to establishing better linkages to tourism.     

Fishermen’s competitiveness and labour market performance: Evidence from shrimpers in Bangladesh

We conduct an experiment to determine competitiveness among shrimpers who engage in collecting shrimp seeds in the southwestern coastal region of Bangladesh. We then examine how competitiveness affects the labour supply decisions and labour market performance of these shrimpers. Our results show that shrimpers who prefer competition are more productive than shrimpers who do not prefer competition. Competitive shrimpers secure better prices and earn higher incomes selling their catches. We estimate that their wage elasticity of participation ranges from 0.4 to 0.5, which is consistent with preferences under neoclassical assumptions. Competitive shrimpers have a slightly greater wage elasticity than non-competitive shrimpers, suggesting that they might be more responsive to expected earnings. Our results have important policy implications for the efficient management of common pool resources.
