Resumen
The quality of drinking water differs across countries, so households show different levels of willingness to pay (WTP) to improve it, which is
also influenced by their income levels. This study presents a meta-analysis using studies from 30 developed and developing countries, repre senting 4.7 billion inhabitants. At the international level, by standardizing these values (PPP) to international US dollars of 2011, developing
countries show, on average, a greater WTP than developed countries relative to their income and an inverse correlation between their water
footprint and their WTP.
