“…Drawing on method of Datt (1998), we utilize this data to obtain estimates of Beta Lorenz Curve (Kakwani, 1980) or Quadratic Lorenz Curve where Beta is not performing (Villasenor and Arnold, 1989). These Lorenz curves take the following forms:…”

“…For example whereas "Botswana's middle class were at the upper limit with 48% of its population classified as middle class, Gabon was at the lower limit of the next category of the classification with 75% of its population classified as middle class. Algeria was the next nation to show upward trend with respect to the overall growth of the middle class with 77%, Egypt with 80%, Morocco having 85% and Tunisia 90%" (AfDB, 2011;Villasenor & Arnold, 1989;Kakwani, 1980;Ravallion & Huppi, 1991;Datt, 1998;World Wealth Report, 2009;Lynch, 2009). …”

Objective: We investigated middle class' contribution to corruption in Sub-Sahara Africa. We assessed the effect of how the upward mobility of the middle class would be driven, if the underlying socio-economic conditions were to be improved. The third inquiry focused on whether the people appeared conflicted, where they seemed to have two separate personalities of "one for Caesar" and the "other for God" in the conduct of their official and professional duties. We finally assessed if exposure to a good dose of ethics would mitigate corrupt practices. Method: Using Ghana as the case study, we conducted a review of the literature on corruption in Sub-Sahara to assess if the phenomenon was growing with the middle class. These included published research on corruption and on the middle class in Sub-Sahara Africa. Grey literature, various government commissions' report after investigations into allegations and cases of corruption, as well as reports of the national Public Accounts Commission and those of the Controller Accountant General's available to the public on the internet was reviewed. All the findings were grouped into their respective units and the issues summarized and interpreted.

“…Two functional forms are frequently used to capture Lorenz curves: the General Quadratic Lorenz function (Villasenor and Arnold, 1989) and the Beta Lorenz function (Kakwani, 1980) for which there is widely available freeware (POVCAL) 4 to estimate the underlying parameters and poverty indices commonly used in the development literature (see also Datt, 1998 for further details). Once the parameters of the Lorenz function are estimated, it is possible to use established results to compute the amount of growth required to meet MDG1 without changes in income distribution, and alternatively the amount of reduction in inequality needed to achieve MDG1 without growth.…”
