2 Economic inequality and political instability Data from Russett (1964), in GIFI Economic inequality Agricultural inequality GINI : Inequality of land distributions FARM : % farmers that own half of the land (> 50) RENT : % farmers that rent all their land Industrial development GNPR : Gross national product per capita ($ 1955) LABO : % of labor force employed in agriculture Political instability INST : Instability of executive (45-61) ECKS : Nb of violent internal war incidents (46-61) DEATH : Nb of people killed as a result of civic group violence (50-62) D-STAB : Stable democracy D-UNST : Unstable democracy DICT : Dictatorship

5 Building composite indicators 1.Separately for each block (without taking into account the other blocks). 2.For each block, taking into account all the other blocks (multi-block data analysis). 3.For each block, taking into account the causal model (Structural Equation Modelling).

6 1. Using SEM for factor analysis Measurement model

7 ULS algorithm S = Observed covariance matrix for MV Goodness-of-fit Index (Jöreskog & Sorbum): = PCA when

8 First result This solution is not admissible because

9 A solution The variance of residual e2 is fixed to a small value

10 Result 2 The variance of residual e2 is fixed to a small value:

11 Bootstrap Results Regression Weights: Composite indicator

12 Principal component analysis with SEM The variance of the residuals are fixed to 0 :

13 Result 3 The variance of the residuals are fixed to 0 :

14 Bootstrap Results Regression Weights: Conclusion

15 Result 4 The variance of the residuals are fixed to 0 :

16 Bootstrap Results Regression Weights: Composite indicator

17 2. Using SEM for multi-block data analysis

18 Result 5 This solution is not admissible because

19 Result 6 Var(e2) is fixed to a small value

20 Result 7 MacDonald (1996) proposal All Var(e) are fixed to 0:

21 Bootstrap Results Regression Weights: Conclusion

22 Result 8 MacDonald (1996) Proposals: (1) All Var(e) are fixed to 0: (2) Composite indicator:

23 3. Causal model estimation using SEM-ULS

24 Result 9 This solution is not admissible because

25 Result 10 Var(e2) is fixed to a small value

26 Bootstrap Results Regression Weights: Conclusion
