We present results from a randomized controlled trial in Bangladesh that introduced operational practices to improve energy efficiency and reduce emissions in 276 "zigzag" brick kilns. 65% of intervention kilns adopted the improved practices. Treatment assignment reduced energy use by 10.3%...

This research provides a status-based explanation for the persistent increase in female labor force non-participation (FLFNP) that often accompanies economic development. This explanation is based on the idea that households or ethnic groups in developing economies can signal their wealth, and...
