In this paper, we study the determinants of rental values in urban housing markets in Kigali, Rwanda.

In particular, we study the value of access to piped water; due to the high costs associated with installing new piped connections, renting a property with an existing connection is often the only way for low income households to access piped water. Our results indicate that extending the piped network to a new house will in many cases raise the rental value of the house enough to pay for the cost of installing the new connection in less than two years.

We examine the effect of the introduction of uniform water-charging for aquifer management and provide evidence using a survey-based choice experiment of agricultural water users in rural Tunisia. Theoretically, we show that the implementation of the proposed second-best regulation would result both in efficiency gains and in distributional effects in favour of small landholders. Empirically, we find that resistance to the introduction of an effective water-charging regime is greatest amongst the largest landholders.

This study used household survey data from four Kenyan towns to examine the effect of households' characteristics and risk perceptions on their decision to treat/filter water as well as on their choice of main drinking water source. Because the two decisions may be jointly made by the household, a seemingly unrelated bivariate probit model was estimated. It turned out that treating non-piped water and using piped water as a main drinking water source were substitutes.
