Low adoption of productive agricultural technologies is a puzzle. Agricultural extension services rely on external agents to communicate with farmers, although social networks are known to be the most credible source of information about new technologies. We conduct a large-scale field...

In order to induce farmers to adopt a productive new agricultural technology, we apply simple and complex contagion diffusion models on rich social network data from 200 villages in Malawi to identify seed farmers to target and train on the new technology. A randomized controlled trial compares...

There has been considerable debate regarding the efficacy of international aid in meeting the dual goals of human development and environmental sustainability. Many donors have sought to engage with this challenge by introducing environmental safeguard and monitoring initiatives; however,...

In this paper we update previous work that categorizes foreign aid projects in terms of their likely impact on the natural environment. We then document trends in the global distribution of environmental aid over time and show that environmental aid has increasingly focussed on global...

We investigate whether the political leaders of aid-receiving countries use foreign aid inflows to further their own political or personal interests. Aid allocation biased by leaders selfish interests arguably reduces the effectiveness of aid, negatively affecting development outcomes. We...

This article investigates whether China’s foreign aid is particularly prone to political capture by political leaders of aid-receiving countries. Specifically, we examine whether more Chinese aid is allocated to the political leaders’ birth regions and regions populated by the ethnic group...

Chinese aid comes with few strings attached, allowing recipient country leaders to use it for domestic political purposes. The vulnerability of Chinese aid to political capture has prompted speculation that it may be economically ineffective, or even harmful. We test these claims by estimating...

This paper studies the causal effect of transport infrastructure on the spatial concentration of economic activity. Leveraging a new global dataset of geo-located Chinese government-financed projects over the period from 2000 to 2014 together with measures of spatial inequality based on...

Bilateral donors use foreign aid to pursue soft power. We test the effectiveness of aid in reaching this goal by leveraging a new dataset on the precise commitment, implementation, and completion dates of Chinese development projects. We use data from the Gallup World Poll for 126 countries over...

This paper studies the causal effect of transport infrastructure on the spatial distribution of economic activity within subnational regions across a large number of developing countries. To do so, we introduce a new global dataset of geolocated Chinese grant- and loan-financed development...
