Using a Quantity Based Demand System (QBDS), the authors determine that demand for labelled appliances is significantly more elastic than for non-labelled ones, with own-price elasticity for labelled goods ranging from -1.2 to -13.2. The research suggests that while Spanish subsidy programmes (paying €50 to €90) may have slightly overestimated the necessary premium, they have been highly successful, as nearly all dishwashers currently sold in the market are labelled A or A+.","ai_generated":true,"unit":"bc3res-000061#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"The hedonic price estimation indicates that an energy efficiency label (class A+) increases the price of a dishwasher by 15.6% ceteris paribus.","ai_generated":true,"unit":"bc3res-000061#insight-1","date_modified":"2026-10-23"},{"text":"Based on an average dishwasher price of €514, the price premium for an energy efficient labelled product is approximately €80.","ai_generated":true,"unit":"bc3res-000061#insight-2","date_modified":"2026-10-23"},{"text":"Demand for labelled dishwashers is significantly more elastic than for non-labelled ones; for a non-labelled own-price elasticity between -0.5 and -2, the labelled demand elasticity ranges from -1.2 to -13.2.","ai_generated":true,"unit":"bc3res-000061#insight-3","date_modified":"2026-10-23"},{"text":"The Quantity Based Demand System (QBDS) is found to be a robust and less data-demanding alternative to the Linear Almost Ideal Demand System (LA/AIDS) for estimating elasticities of close substitutes.","ai_generated":true,"unit":"bc3res-000061#insight-4","date_modified":"2026-10-23"},{"text":"Spanish subsidy programmes for energy-efficient appliances, which provide between €50 and €90, have been extremely successful, resulting in nearly all market offerings being labelled A or A+.","ai_generated":true,"unit":"bc3res-000061#insight-5","date_modified":"2026-10-23"}],"climate_tags":["energy efficiency","climate policy","subsidy"],"geography_discussed":["Germany","Switzerland","Shanghai"],"frame_perspective":[],"analysis_type":["econometric analysis","hedonic price method","demand system modelling"]}]}
