In measuring the spatial cost of living, the recent literature underscores the importance of detailed product quality information in the price data. Taking advantage of the price data availability in Ghana, this case study explores the Consumer Price Index price data as a source for spatial price measurement.

The empirical analysis indicates a potential bias in estimating spatial prices stemming from the lack of product quality information and, therefore, suggests the potential usefulness of the Consumer Price Index price data for spatial price adjustment in poverty analysis in low- and middle-income countries. 2020-09-17T19:03:56Z 2020-09-17T19:03:56Z 2020-09 Working Paper http://documents.worldbank.org/curated/en/851571599590950719/How-Useful-is-CPI-Price-Data-for-Spatial-Price-Adjustment-in-Poverty-Measurement-A-Case-from-Ghana http://hdl.handle.net/10986/34474 English Policy Research Working Paper;No. 9388 CC BY 3.0 IGO http://creativecommons.org/licenses/by/3.0/igo World Bank World Bank, Washington, DC Publications & Research Publications & Research :: Policy Research Working Paper Africa Ghana
