New research in rural Costa Rica suggests community-based monitoring can improve water management

New research published in PNAS suggests that community-based monitoring can improve water management in rural Costa Rica by reducing groundwater extraction and improving water quality. The program, which used a smartphone application and WhatsApp, showed modest but significant effects after one year.

New analysis reveals how region-wide policies might be ineffective in eliminating local risk factors for coronavirus spread

Researchers found regional lockdowns did not sufficiently address local COVID-19 risk differences in Italy. Instead, targeted interventions focused on high-risk areas could help strike a better balance between public health and economic damage. The study provides guidance for policy-makers to design effective interventions.

Gender pay gap means fewer female candidates on the ballot

A new study finds that electoral districts with a larger gender pay gap tend to have fewer female candidates, as voters' biases against women candidates can lead to lower vote shares. The Parity Law has had limited impact in reducing this disparity, with parties strategically allocating female candidates to less competitive districts.
