Simple Tools To Evaluate Political Projects (4)

Let's bring back the income distribution data from the previous post.

Income share in % 1986/7 1991/2 1996/7 2001/2 2006/7 2012
Bottom 20%              5.6      6.4      5.9      6.2     6.1      5.4
Top 20%                  44.2    43.5    46.2    44.8    45.6    47.5
Ratio                         7.9       6.8      7.8      7.2      7.5      8.8

After Bheenick and Bunwaree had reversed some of the damage of policies of Sithanen, Berenger and Pravind Jugnauth reduce slightly the share of the bottom 20% while they increase that for the top 20% by 0.8%. Finally after the first five years of the Sithanen flat tax the weakest 20% households see their share fall to at least a 25-year low while the top 20% hit a record level of 47.5% after they get an increase of 1.9%. There is little surprise then in seeing the share ratio reach a record 8.8X.

So each time Sithanen has been Finance Minister inequality has increased. After his first stint the top 20% saw their share rise by 2.7% of GDP and his flat tax has handed this group another 1.9% in 2012 while the bottom quintile have seen their share fall by 0.5% and 0.7% after his stints or toxic policies were implemented. Lutchmeenaraidoo, Bheenick and Bunwaree on their side have reduced inequality when they were Finance Minister. At this point in time it is useful to have another look at the different cakes that were baked.


We can see that not only the biggest cake was produced by Vishnu in the five years ending in 1992 but the sharing was also the best for the bottom 20% as they grabbed a 6.4% share. Compare this to the smallest share of the bottom 20% and one of the smallest cake produced in the first five and half years of the Sithanen flat tax. There are other interesting conclusions you can draw from combining these two data sets. Have fun. We'll return with a few more tools.
