Sum m ary. The paper has applied a con vention al fram ework of analysis of im plicit markets to determ ine the charac teristics of dem and for housing attrib utes of quantity and quality in the urban areas of a large, low -incom e develop ing cou ntry like Pakistan . Incom e elasticit ies gen erally appear to be low , alth ough som ew hat higher for indicators of quality. O wn-price elasticit ies are high while the cross-p rice effects with resp ect to different attrib ute prices reveal the high degree of substitu tibility am ong these attrib utes. M ethodological innovation s in the paper include the use of a weigh ted factor score for the m easurem ent of housing quality and incorp oration of the effect of changes in non-housing prices on dem and for housing attrib utes. G iven the large m agn itude of own-price effects and the negative im pact of a rise in non-housing prices, it appears that in the face of slow grow th in real incom es and double-d igit in¯ation in Pakistan resid ential overcro w ding con dition s are likely to w orsen over time.
