Spatial dependence

Spatial dependence of per capita property tax income in South Africa

We investigate spatial dependence of per capita property tax income among South African municipalities. One original contribution of our study is the use of per capita property tax income, rather than the property tax rate, as the outcome variable. Per capita property tax income is indicative of tax burden on residents. In addition, whilst most studies focus on advanced countries that have had institutionalised fiscal decentralisation for many decades, this paper focuses on South Africa, which is a developing country and implemented fiscal decentralisation only 18 years ago.

Assessing regional variation in the effect of the removal of user fees on institutional deliveries in rural Zambia

This paper examines regional differences in the effect of user fee removal in rural areas of Zambia on the use of health institutions for delivery. The analysis uses quarterly longitudinal data covering 2003q1-2008q4. When unobserved heterogeneity, spatial dependence and quantitative supply-side factors are incorporated in the Interrupted Time Series (ITS) design, user fee removal is found to immediately increase aggregate institutional deliveries, although the national trend was unaffected.
