Social Networks

Community Cellular Networks

Despite the rapid global expansion of mobile phone coverage, many isolated, rural communities do not have connectivity. In the Philippines, we are evaluating the impact of installing cellular towers and providing free SIM cards for mobile phone use on communication activity and frequency, social ties, access to information, migration and labor market outcomes, bargaining power and market prices, and income and employment decisions.

Leveraging Social Connections

Identifying eligible beneficiaries for social programs, a process known as “targeting,” can be a challenging and costly process for development and humanitarian organizations. Many widely-used targeting strategies were developed for rural environments and may not work as well in dynamic and densely populated urban centers. One potential new technique is “decentralized targeting,” a process that relies on information from socially knowledgeable members of a community. In Liberia, we conducted a randomized evaluation to measure the effectiveness of decentralized targeting in reaching poor households and households that have experienced an economic or health shock. Preliminary results find that both the proxy means test and decentralized targeting were prone to error – the majority of households identified by both were not the poorest.

The Impacts of Psychosocial Support and Cash for Work on Vulnerable Youth in Liberia

Over the past two decades, sports programs have proliferated as a way to engage youth in productive activities, especially in contexts marked by conflict and high unemployment. Believed to lead to better labor market outcomes for marginalized youth, many sports programs aim to improve psychosocial well-being and soft skills of participants. In Liberia, we worked with Mercy Corps to evaluate the impact of a sports and life skills development program on psychosocial and labor outcomes of vulnerable young people. While the program had no effect on improved psychosocial well-being or resilience, it did lead to an increase in labor force participation.

Job Networks and Gender in Malawi

In developing countries, women are commonly underrepresented in the formal sector. One potential explanation is that a large proportion of these jobs are secured through informal channels, including employee referrals, which may disadvantage women. We examined how informal job referral systems affect labor market participation for women in Malawi using a randomized evaluation and found that informal referral schemes systematically disadvantaged qualified women.

The Impact of Mobile Phones: Experimental Evidence from the Random Assignment of New Cell Towers

We present experimental evidence on the economic impacts of mobile phone access. Our results are based on a randomized control trial in the Philippines, through which 14 isolated and previously unconnected villages were randomly assigned to either …

Connecting Isolated Communities: Quantitative Evidence on the Adoption of Community Cellular Networks in the Philippines

What determines the success of community cellular networks? And who uses the network? We leverage unique circumstances where all households in seven localities were interviewed before the installation of cellular network towers. We observed large …

Stay in the Game: A Randomized Controlled Trial of a Sports and Life Skills Program for Vulnerable Youth in Liberia

Over the past two decades, sports programs have proliferated as a mode of engaging youth in development projects. Thousands of organizations, millions of participants, and hundreds of millions of dollars are invested in sports-based development …

Do Job Networks Disadvantage Women? Evidence from a Recruitment Experiment in Malawi

We use a field experiment to show that referral-based hiring has the potential to disadvantage qualified women, highlighting another potential channel behind gender disparities in the labor market. Through a recruitment drive for a firm in Malawi, we …
