Despite the evolving literature on the development benefits of mobile phones, we still know very little about factors that influence their adoption. Using twenty five policy variables, we investigate determinants of mobile phone penetration in 49 Sub-Saharan African countries with data for the...

I use the quasi experimental nature of the roll-out of the mobile phone network in Mozambique to estimate the impact of search costs on the dispersion of maize prices and transport costs. The introduction of mobile phone services from 1997 to 2009 explains a 4.5-11% percent reduction in price...

Recently, policy makers worldwide have suggested and passed legislation to ban mobile phone use in schools. The influential and only quantitative evaluation by Beland and Murphy (2016), suggests that this is a very low-cost but effective policy to improve student performance. In particular, it...

We investigate to what extent the roll-out of the mobile phone network in Mozambique reduced transport costs and search costs, and thereby decreased spatial price dispersion and improved market efficiency. Estimations are based on data of transport costs of maize grain and maize market prices....

This paper studies the peer effect of iPhone adoptions in China. We use a unique data set of iPhone adoption records from a provincial capital city in China, in a span of over four years starting from iPhone's first introduction to mainland China. We construct a social network using six month's...

During the last 10-15 years, mobile phone technologies have been widely adopted in most developing countries, including adoption by rural households that never had access to landline phones before. Existing research shows that use of mobile phones has improved market access for smallholder...

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...

Rapid and constant development of technology and social media drive every-day changes in the retail sector, modifying behaviour and power of consumers, whereby traditional brick and mortar stores are facing the risk to become obsolete. E-commerce and m-commerce offer to customer a more...

The digital revolution and the ongoing dissemination of mobile phones carry several prospects for smallholder farmers in Sub-Saharan Africa. Food insecurity remains a major issue among African smallholders. Mobile phones could potentially facilitate access to food markets and thus improve food...

We measure the impact of search costs on farmers' and traders' transaction prices in Mozambique by investigating to what extent the introduction of mobile phones has affected the margin between recorded maize producer and retail market prices, and by exploring if producers or traders benefit...
