BARROS, Carlos  e  WANKE, Peter. Cost efficiency of African insurance companies using a finite mixture model. S. Afr. j. econ. manag. sci. [online]. 2016, vol.19, n.1, pp.64-81. ISSN 2222-3436.  http://dx.doi.org/10.17159/2222-3436/2016/v19n1a5.

This paper evaluates the operational practices by African insurance companies from Angola and Mozambique, using a finite mixture model that allows controlling for unobserved heterogeneity. More precisely, a stochastic frontier latent class model is adopted in this research to estimate the cost frontiers for each of the different technologies embedded in this heterogeneity. This model not only enables the identification of different groups of African insurance companies from Angola and Mozambique, but it also permits the analysis of their cost efficiency. The results indicate the existence of three different technology groups in the sample, suggesting the need for different business strategies. The policy implications are also derived.
