Under the Paris Agreement, each country submits national pledges that reflect common but differentiated responsibility. Policy-makers therefore need to understand the mitigation policy interests of domestic populations, especially in developing countries where survey data are relatively scarce....

We study how extreme weather exposure impacts infant survival in the developing world. Our analysis overcomes the absence of vital registration systems in many poor countries by extracting birth histories from household surveys. Studying 53 developing countries that span five continents, we find...

This article contributes to the growing scholarship on how ethnic inequality can dampen the provision of public goods and services. On the one hand, it pushes beyond purely economic inequality to include status inequality between population groups. On other hand, it moves away from the provision...

How much did rural sanitation in India change under the five years of the Swacch Bharat Mission? The best nationally representative statistics on sanitation in India have long come from the Demographic and Health Surveys, known as the National Family and Health Surveys in India. The fifth round,...

Utilitarianism is the most prominent family of social welfare functions. We present three new axiomatic characterizations of utilitarian (that is, additively separable) social welfare functions in a setting where there is risk over both population size and the welfares of individuals. First, we...

The expectation of a sum of utilities is a core criterion for evaluating policies and social welfare under variable population and social risk. Our contribution is to show that a previously unrecognized combination of weak assumptions yields general versions of this criterion, both in...

Population ethics is widely considered to be exceptionally important and exceptionally difficult. One key source of difficulty is the conflict between certain moral intuitions and analytical results identifying requirements for rational (in the sense of complete and transitive) social choice...

Three important features of Indian labor markets enduringly coexist: rent-seeking, occupational immobility, and caste. These facts are puzzling, given theories that predict static, equilibrium social inequality without conflict. Our model explains these facts as an equilibrium outcome. Some...

The population literature in theoretical economics has long focused on attempts to avoid the repugnant conclusion. We advance the literature by proving that no social ordering in population economics can escape the repugnant conclusion in all instances. As we show, prior results depend on a...
