The use of air quality monitoring networks to inform urban policies is critical especially where urban populations are exposed to unprecedented levels of air pollution. High costs, however, limit city governments’ ability to deploy reference grade air quality monitors at scale; for instance, only 33 reference grade monitors are available for the entire territory of Delhi, India, spanning 1500 sq km with 15 million residents. In this paper, we describe a high-precision spatio-temporal prediction model that can be used to derive fine-grained pollution maps. We utilize two years of data from a low-cost monitoring network of 28 custom-designed low-cost portable air quality sensors covering a dense region of Delhi. The model uses a combination of message-passing recurrent neural networks combined with conventional spatio-temporal geostatistics models to achieve high predictive accuracy in the face of high data variability and intermittent data availability from low-cost sensors (due to sensor faults, network, and power issues). Using data from reference grade monitors for validation, our spatio-temporal pollution model can make predictions within 1-hour time-windows at 9.4, 10.5, and 9.6% Mean Absolute Percentage Error (MAPE) over our low-cost monitors, reference grade monitors, and the combined monitoring network respectively. These accurate fine-grained pollution sensing maps provide a way forward to build citizen-driven low-cost monitoring systems that detect hazardous urban air quality at fine-grained granularities.
Alfred Marshall and Mary Paley Marshall are often described as the first academic economist couple. Both studied at the University of Cambridge, where Paley became one of the first women to take the Tripos exam and the first female lecturer in economics, with Marshall’s encouragement. But in later life, Marshall opposed granting Cambridge degrees to women and their participation in academic economics. This paper recounts Alfred Marshall’s use of gender norms, born out of a separate spheres ideology, to promote and ingrain women’s exclusion in academic economics and beyond. We demonstrate the persistence of this ideology and resultant norms, drawing parallels between gendered inequities in labor market outcomes for Cambridge graduates in the UK post-Industrial Revolution and those apparent in cross-country data today. We argue that the persistence of the norms produced by separate spheres ideologies is likely to reflect, at least in part, the rents associated with preferential access to better paid, high-skilled labor market opportunities. In doing so, we ask who benefits from gender norms, who enforces them, and suggest relevant policy work and areas for future research.
Can increasing control over earnings incentivize a woman to work, and thereby influence norms around gender roles? We randomly varied whether rural Indian women received bank accounts, training in account use, and direct deposit of public sector wages into their own (versus husbands') accounts. Relative to the accounts only group, women who also received direct deposit and training worked more in public and private sector jobs. The private sector result suggests gender norms initially constrained female employment. Three years later, direct deposit and training broadly liberalized women's own work-related norms, and shifted perceptions of community norms.

Can e-governance reforms improve government policy? By making information available on a real-time basis, information technologies may reduce the theft of public funds. We analyze a large field experiment and the nationwide scale-up of a reform to India's workfare program. Advance payments were replaced by "just-in-time" payments, triggered by e-invoicing, making it easier to detect misreporting. Leakages went down: program expenditures dropped by 24 percent, while employment slightly increased; there were fewer fake households in the official database; and program officials' personal wealth fell by 10 percent. However, payment delays increased. The nationwide scale-up resulted in a persistent 19 percent reduction in program expenditure.
The prevalence of vote-buying is widely identified as a cause of poor governance in the developing world; potential mechanisms for this relationship include the selection of lower quality politicians, and the reduced accountability experienced by politicians once elected. In this paper, we present the first experimental evidence in support of the second channel of reduced accountability. Using data from laboratory experiments conducted in the U.S. and Kenya, we find that vote payments reduce voters' willingness to hold politicians accountable: holding fixed politician identity, voters who receive payments are less willing to punish the politician for rent-seeking, and this reduction in punishment is larger in magnitude when payments are widely targeted. Unsurprisingly, the politician then engages in a higher level of rent-seeking. A simple model of multi-faceted social preferences encompassing reciprocity and inequality aversion is consistent with these findings.
Millions of the world’s poorest people now live in middle-income democracies that, in theory, could use their resources to end extreme poverty. However, citizens in those countries have not succeeded in using the vote to ensure adequate progressive redistribution. Interventions aiming to provide the economically vulnerable with needed resources must go beyond assisting them directly, they must also improve democratic institutions so that vulnerable populations themselves can push their representatives to implement redistributive policies. Here, I review the literature on such interventions and then consider the “democracy catch-22”: How can the poor secure greater democratic influence when the existing democratic playing field is tilted against them?
