  • Global variations in online privacy concerns across 57 countries

    • Cross-cultural studies have found national differences in how concerned people are about online privacy. However, it has not yet been settled what causes this variation, and several factors have been proposed in the literature, including internet habituation, individualism, and uncertainty avoidance. Here we investigate these factors by two studies. In the first, we examine the association between online privacy concerns and a new measure of online self-disclosure norms that we introduce. We find that this measure is significantly associated with two established instruments of online privacy concerns in the literature. In the second, we analyze previously unpublished data from a questionnaire on online self-disclosure norms as assessed by this new measure. It includes replies from 18,046 adult respondents from 57 countries and six continents. We find that norms in favor of more restrictive online self-disclosure are weaker in countries with higher levels of internet penetration (r = −0.56, p < .001). Our findings suggest that higher internet penetration in a country reduces online privacy concerns. The results support the idea that habituation to online environments decreases privacy risk perceptions. An implication is that preferences for online privacy are likely to decline over time in countries where internet penetration is still low. Lastly, in conflict with previous studies, our analyses do not support the theory that online privacy concerns are associated with national cultures related to individualism or uncertainty avoidance as measured by Hofstede's indices.

  • Green Vehicles’ Responses to an Expiring Congestion Toll Exemption : Findings from a Natural Experiment in Stockholm, Sweden
  • 2023
  • In: Findings. - : Network Design Lab - Transport Findings. - 2652-8800.
  • Journal article (peer-reviewed)abstract
    • Stockholm established time-varying congestion pricing in 2007, and adopted a toll exemption as a temporary incentive for green vehicles (GVs) that ended in 2012. We examine the behavioral effects of phasing out the exemption by studying the change in cordon crossing events for GV morning commuters between May 2012 and May 2013, with a random sample of conventional vehicles (CVs) as control. The results suggest i) a significant drop in the total number of crossings; ii) a slight shift towards later journeys in the morning; and iii) a reduction in the ratio of peak-toll period crossings to other ones.
