Marica VALENTE (Berlin School of Economics) – “Heterogeneous effects of waste-pricing strategies”
Abstract: Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices—unit prices on household unsorted waste disposal—on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. I find evidence of nudge effects at low prices, and increasing elasticities at high prices driven by income effects and waste habits before policy. Second, I estimate policy impacts on pollution and municipal management costs, and compute the overall social cost savings for each municipality. Social welfare effects become positive for most municipalities after three years of adoption, when waste prices cause significant waste avoidance.
