Monarchy & Republic: In the Laboratory of History

Which form of government actually performs better: monarchy or republic?
Monarchy & Republic: In the Laboratory of History approaches this question through empirical comparison rather than political belief or historical reputation. Using cross-national data, it compares monarchies and republics across five fundamental goals of government: welfare, security, order, justice, and liberty.
The book examines international indicators, statistical evidence, and differences among constitutional and non-constitutional monarchies, republics, and Commonwealth countries. It also considers alternative explanations such as geography, natural resources, culture, history, and development.
The aim is not to defend a political tradition, but to ask a simple question: When governments are judged by their measurable results, what does the evidence actually show?
