The Inter-relationship between Anti-Corruption and Political Stability:Evidence Using Cross-Country Panel Data

In this paper, we classify 68 countries into four groups (Total countries, OECD, Country GroupⅠ, Country GroupⅡ) during 1998-2006. The endogeneity tests demonstrate two way causal relationships; anti-corruption, a component of social technology, affecting political stability, and political stability affecting anti-corruption. The empirical evidence is consistent with the hypothesis that an increase in each of these variables causes in the other, ceteris paribus. For example, anti-corruption can be increased by increased level of political stability. Political stability can be enhanced by an increase in anti-corruption. This implies that they complement each other. Therefore, the instrument choice should not be based upon stability analysis of a single final target variables. Both political stability elasticity of anti-corruption and anti-corruption elasticity of political stability appear to be highest in the country group Ⅰ and then OECD group. The country group Ⅱ shows the lowest elasticities.
