Abstract [en]

This paper presents the results of a ranking-type Delphi study on the critical risk factors for the adoption of an electric road system (e-road) for trucks on the main motorways in Sweden. The investment cost of such a system is high, necessitating an upfront evaluation of the adoption risk factors to reduce the likelihood of budget overruns and project delays. Participating Swedish e-road experts (N = 52) from the public sector, private sector, and academia identified 32 unique risk factors, which were divided into five categories. The three most critical risk factors, as ranked by the experts, were ‘low expansion rate,’ ‘low utilization rate,’ and ‘lengthy public-sector evaluation.’ Overall, market and financial risks were ranked as more important than institutional, technological, and sustainability risks. This study has important implications for policymakers in countries considering e-road adoption.

Abstract [en]

This study analyzes the determinants of road freight companies' adoption intention regarding the electric road systems (e-roads) on Swedish motorways. A research model was developed based on the technology adoption literature and Technology-Organization-Environment (TOE) framework. Survey data were gathered from 160 Swedish road freight companies, and structural equation modeling was performed to test the model empirically. The results reveal relative advantage, a technology characteristic, as the main determinant of road freight companies' intention to adopt electric road systems. The study contributes to the TOE framework by reporting on the indirect effects of technological and organizational determinants on organizational intention to adopt technologies. © 2023 World Scientific Publishing Company.

Abstract [en]

Mobile app ratings and reviews are important due to their influence on consumer behavior and the financial consequences for app developers and app platform providers. This paper contributes to prior work by analyzing how rating and review information in combination impact mobile app downloads. To achieve these ends, we utilize daily panel data of 341 gaming (hedonic consumption value-oriented) and productivity (utilitarian consumption value-oriented) apps tracked for almost two years from their release in the Apple App Store. Hence, we contribute to how ratings and reviews matter for the larger majority of apps, whereas previous research has mainly focused on either ratings' or reviews' impact on app performance for top-ranked apps. Results of fixed-effects regression analysis reveal different combinatory impacts of text review information (polarity, subjectivity, and review length) and rating information (average rating score, volume of ratings, and dispersion of ratings) on gaming versus productivity app downloads. Important implications of the findings for app developers and platform providers, and for future research into online ratings and reviews, are discussed.

Abstract [en]

The many challenges faced by instructors in distance education have been extensively documented in current literature. Nevertheless, the relative importance of such challenges has not been researched to the same extent. As instructors and institutions face limitations in terms of time and budget, the ability to effectively prioritise challenges becomes increasingly vital. This paper aims to investigate the relative importance of various distance education challenges to instructors. For this purpose, a ranking-type Delphi study of 90 instructors was conducted at a Swedish higher education institution of technology. In total 26 unique challenges were identified, out of which the top 13 challenges were further ranked by instructors. The ranking revealed that pedagogical challenges were regarded as being of highest relative importance, whereas technological and organisational challenges were of lesser significance. Instructors rated the following challenges as the most significant: lack of student responsiveness, diminished collaboration due to social distancing among students, substantial upfront course design investments by instructors, and limitations in instructor accessibility. These rankings were found to be largely consistent across different instructor characteristics. The findings of the study indicate the importance of investing in faculty training and support functions within higher education institutions to ensure the quality of distance education.

Abstract [en]

This paper explores key drivers and their underlying rationales for infrastructure Public-Private Partnership (PPP) adoption in Sweden. A related aim is to compare the identified key drivers for Sweden in relation to what is known for other countries. Data was collected via semi-structured interviews with 16 Swedish private sector and public sector stakeholder PPP experts. The results reveal risk transfer to the private sector, reduction of total project costs, and increase in investment alternatives as particularly important key drivers in the case of Sweden. In a country comparison of key drivers Sweden was not found to mirror any specific country or group of countries, calling for deeper analysis. Moreover a few underlying rationales put forth for key drivers were in addition to those reported in the literature. This study contributes to the literature by identifying conducive factors for PPP adoption given sparse and infrequent past country use. Hence, the findings should be considered for Sweden and countries similar to it.

Abstract [en]

When launching a new app in one of the major app stores, the developer must decide how to generate revenues from that app. The decision includes whether to charge an upfront payment from the customer or make it free to download and whether to include in-app payments. In this study, we analysed the effect of these decisions on the amount of revenue an app generates and if it differs for gaming (hedonic value-orientation) and productivity (utilitarian value-orientation) apps. To analyse this effect, we used approximately two years of mobile app panel data from 330 newly launched US Apple App Store gaming and productivity apps. Based on random effects regression analysis, we report that free downloads combined with in-app payments are superior in revenue generation for gaming apps. By contrast, for productivity apps, relying only on either upfront payment for the app or on in-app payments generates the highest revenues. For gaming app developers, offering free to download apps is thus recommended. For productivity app developers, charging for either downloading or in-app features is more successful. This study complements existing literature by investigating revenue generation of new apps and the performance effect of specific revenue model options that developers must make in app store settings.

Abstract [en]

Consumers tend to rely more on peer information than seller information for their online product choices. Online rating systems have therefore become popular whereby consumers evaluate a product’s quality on a numerical scale. Previous studies have mainly investigated sales effects of online ratings, reporting mixed findings. How online ratings impact free app downloads is important to better understand for multiple and related reasons. Specifically, the vast majority of apps are free to download, price cannot be used by potential consumers to infer app quality, and providers may offer free apps as a means to gain market share. In this paper we analyse how average rating score, volume of ratings, and dispersion of ratings impact free app downloads. Signaling theory is used to derive hypotheses on how online rating variables impact in this regard. Data on online ratings and downloads of apps was collected for 720 apps available on Apple App Store and Google Play. Apps from the productivity and game categories were sampled to capture utilitarian and hedonic apps respectively. This choice was made to enable analysing the impact of online ratings across app type. For free app downloads, regression analyses revealed: (1) volume of ratings to have positive significant effect; (2) average rating score to have positive but insignificant effect; and (3) dispersion of ratings to have positive significant effect contingent on app type. Findings are partially consistent with signaling theory and suggest that app rating providers should attempt to attract large volume of ratings. Providing incentives for rating apps, or using a pledge in the app asking consumers to rate it, could be such means. Future research is needed on whether average rating scores are too similar for competing app alternatives to guide app choice. Further research is also needed on why dispersion of ratings positively impacts free app downloads.

Abstract [en]

This paper develops and tests a motivational model to explain the overall continuance intention to use computers and smartphones. Based on survey data from 192 undergraduate students, structural equation modeling analysis is used to report: (1) independent effect of intrinsic motivation on the continuance intention to use computers and smartphones; (2) independent effect of extrinsic motivation on the continuance intention to use computers but not smartphones; (3) intrinsic motivation mediating the effect of extrinsic motivation on the continuance intention to use computers; (4) Independent effect of technology cognizance on the continuance intention to use computers but not smartphones; (5) intrinsic motivation positively influencing extrinsic motivation and technology cognizance, with respect to both devices. This research contributes to an improved understanding of the independent and interrelated effects of intrinsic and extrinsic motivations to use technological devices. The findings have important implications for theory and practice regarding the overall use of technology.

Abstract [en]

Lead userness (LU) captures to what extent a user, in a given product domain, is ahead of an important market trend and expects high benefits from innovating. A comprehensive understanding of antecedents and consequences of LU are important to both theory and practice. To lead-user theory, a more comprehensive understanding of antecedents such as intrinsic motivation may contribute to improved knowledge of the underlying motivational mechanisms that explain why some users display LU. Similarly an improved understanding of consequences may help explain why these users provide advice to other consumers or often come up with attractive innovations. To practice, such knowledge may provide insights on how to identify these users at lower cost as well as how to get use of them for developing or promoting new products.

Previous studies have investigated different antecedents and consequences in different product domains. Therefore, there is a need to further investigate the previously studied antecedents and consequences in more domains. This way a more comprehensive understanding of the relative importance of different antecedents and consequences within and across product domains can be gained.  Some antecedent may thus be more domain-specific than other ones.

In the current study we therefore set out to investigate three previously studied antecedents of LU: consumer knowledge, intrinsic motivation and extrinsic motivation. In addition we study a fourth antecedent, technology cognizance, which may be of particular importance in the information technology intense domain we study. Further, two previously studied consequences of LU, opinion leadership and opinion seeking, are researched in the present study of the mobile application domain.

Based on a survey study of 156 undergraduate students we report in a series of regression analyses: (1) consumer knowledge to be the only antecedent of LU; (2) opinion leadership and opinion seeking to be consequences of LU, the former being a relatively more important one, and; (3) Our findings to overall correspond highly to findings in researches of other domains ranging from extreme sports such as kite-surfing and sailplaning to the mass market of home kitchen appliances. Implications for research and practice are provided.

Abstract [en]

The zero‐price effect implies that people forgo a favourable option for a free one, not only because the free one brings no cost but also because it creates a higher positive feeling which people use in making decisions. We extend previous studies by testing this effect for three‐component online mobile services in a business‐to‐business context. Two survey experiments are conducted using a sample (N=113) of Swedish hauler managers. In none of the experiments we find any zero‐price effect. Free promotions may therefore be less effective in the business‐to‐business context than in the business‐to‐consumer context.
