Corruption

Rooting out corruption.

Corruption measures a country's bureaucratic morality throughout the ranks. A country with high corruption suffers widely from embezzlement and loss of the leader's authority, while a country with no corruption is free to prosper. Unlike inflation, corruption does not directly affect monetary costs, instead affecting other areas of the state (though it may indirectly affect income due to raising the local autonomy floor of provinces).

Decreased by[edit]

-0.02% per point of stability per year
Maximum of -1% per year for “rooting out corruption”, which is controlled with a maintenance slider on the economy tab. Reducing corruption costs 0.05 ducats per month per total effective development (which is modified by autonomy) for maximum effect. (This can be lowered if the player chooses, although reducing expenditure will decrease the corruption reduction proportionally.)
-0.05% per year for being ahead of time in diplomatic technology.
-0.05% per year for being ahead of time in administrative technology.
-2.00% With using Islamic nation’s "Enforce Faithful Adherence" while having 75 or more piety
