Chapter in Sanitation in Developing Countries, edited by Arnold Pacey, published by John Wiley & Sons (now Wiley), 1978
“There is a small tentacle on the body of micro-economic theory that deals with the behaviour of what economists call ‘inferior goods’. While this topic is rarely of any practical interest, I was delighted to discover a possible application in the field of low-cost waste disposal during the recent trip to East Asia. If the hypothesis is correct that urban wastes exhibit ‘inferior goods’ behaviour, then some interesting theoretical implications can be derived which may aid us in understanding and promoting the diffusion of low-cost technologies of waste disposal.”
