The research paper seeks to establish the causal relationship between the two variables but uses the "dynamic panel generalized method of moment (GMM)". The objective to use this technique in order to determine the extent to which the relationship exists. The research paper aims to examine the strength of the relationship between the two variables and determine whether a democratic form of government is more likely to cause a higher variation in growth in the country. The research builds upon the previous research methodology and goes onto include a wider sample that can be used to generate a stronger conclusion.
The research paper concludes whether the democratic form of a government is a determinant of the volatility of growth of a country or not. The extent to which this relationship is causal or deterministic is also empirically measured however, that is the secondary aim of the research.
