The use of smartphone apps has numerous advantages for app providers and users. However, the users of many smartphone apps are confronted with a trade-off between usage benefits and preferences for personal data protection. We investigate the acceptability of data sharing in different...

As mobile phone ownership rates have risen in Africa, there is increased interest in using mobile telephony as a data collection platform. This paper draws on two pilot projects that use mobile phone interviews for data collection in Tanzania and South Sudan. The experience was largely a...

Mobile phones with banking technology are becoming more readily available in Vietnam. Similarly, many financial institutions and mobile phone service providers are teaming up to provide several banking services to customers via the mobile phone. However, the number of people who choose to adopt...

Estimating the size and places of residence of the population of Ukraine has been this country's problem for the past decade, and is related to the lack of census data for the 2010 round, large-scale processes of external and internal labour migration, and Russia's armed aggression against...

Using data from a non-mobile-optimised survey in the UK, this paper compares the quality of survey data from mobile devices with different screen size. The findings suggest that data quality mainly differs between small smartphones with a diagonal screen size of below four inches and larger...

Mobile phone survey interviewing is becoming increasingly prevalent, so it is important to understand how it affects measurement error. We link cognitive response process theory (Tourangeau et al 2000) to theories of mode effects to build a comprehensive framework that identifies ways in which...

Mobile applications hold promise to foster sustainable mobility behavior, but evaluations of their effectiveness are subject to a number of empirical challenges. We conduct a randomized controlled trial with three distinctive features: unobtrusive tracking of the control group, limited sample...

This paper measures the impact of a micronutrient training among women farmers with young children on the demand for zinc-enhanced varieties. We conducted a randomized control trial by providing micronutrient training in randomly selected villages in May-June 2017. These farmers were also given...

Smartphone apps deliberately apply behavioral design, including algorithms sensing human behavior and personalized design elements affecting it. Untransparent behavioral design exploits an information asymmetry between app vendors and consumers and can lead to negative effects on consumers such...
