Statistical Study: The Effect of Heads of States' Time in Power on Country Wellbeing

The study finds that longer tenures for current heads of state are associated with increased corruption and expanded government powers. It also suggests that historical long-term rulers leave a legacy of structural damage, though countries generally recover over time. The analysis identifies 10 years as a critical threshold beyond which negative effects on country wellbeing become evident.

• There is a correlation between the length of a current head of state's rule and an increase in corruption, the use of public office for private gain, and a decrease in limits on government power.
• Historical long-term rulers leave a lasting legacy of structural damage, including increased state fragility, reduced rights, and more external interventions, which persist even if the successor is less corrupt.
• While most negative impacts of long-term rule diminish over time—including improvements in civil justice, freedom of expression, and the rule of law—illicit financial flows show a strong positive relationship and may actually increase over time.
• The analysis suggests that a tenure exceeding 10 years is 'too long,' as negative effects on the country and long-term legacy damages typically begin to manifest after this period.
• Initial data suggests that more recently independent countries have a lower frequency of heads of state remaining in power for long periods compared to the past.
