Partisan alignment and political corruption: Evidence from a new democracy

I analyze the link between partisan alignment of local politicians and the incidence of political corruption, using novel hand-collected data on local political corruption in Ghana. The empirical analysis, based on 205 districts observed over the period 2013–2018, suggests significantly lower levels of political corruption in aligned districts. Partisan alignment reduces corruption by 1.9 percentage points, equivalent to about half of the mean-level in non-aligned districts. In line with political ambition theory, I attribute this result to local politicians aligned with the national government having incentives to control fiscal irregularities within their localities in order to appease their national party leaders and preserve their party’s reputation. Alternative explanations are considered through empirical means and can be excluded. The estimated effect is more pronounced in districts that (i) are party strongholds, (ii) have better financial endowments, and (iii) have female local parliamentarians. It appears that political centralization and a politicized bureaucracy, as observed in Ghana, are important explanations for this finding.
