Mobile money (MM) services can contribute to welfare gains in smallholder farm households. Previous research showed that one important pathway is through higher remittances received from relatives and friends. Here, the role of other impact pathways is examined, especially focusing on...

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...

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...

This paper evaluates whether competition hinders or spurs investment in a network industry. When a network is split between competitors, potential network effects are foregone. However, a firm may invest in components that are not shared, to steal customers from its competitors. I structurally...

In this project, we analyzed whether mobile phone-based surveys are a feasible and cost-effective approach for gathering statistically representative information in four low-income countries (Afghanistan, Ethiopia, Mozambique, and Zimbabwe). Specifically, we focused on three primary research...

The study assesses the role of mobile phones and mobile banking in decreasing inequality in 52 African countries. The empirical procedure involves first, examining the income-redistributive effect of mobile phone penetration and then investigating the contribution of mobile banking services in...

This paper develops a method to analyze the effects of competition policy in a network industry. Competition has mixed effects on incentives to invest: when a network is split between competitors, each captures only a fraction of potential network effects. However, a firm may invest in...

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....

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 search costs, and thereby lowered transport costs and improved the efficiency of agricultural markets. Estimations are based on data of both maize market prices and transport costs of maize grain....
