Wealth and the Structure of National PowerHow does GDP per capita relate to different dimensions of national power?Ally DentonAmerican University
OverviewNational power is central to debates in international politics, but it isinherently multidimensional. This project examines whether wealth translatesuniformly across different components (economic, military, and technological)of state power.Central Findings•Wealth is positively associated with all dimensions of national power, butnot equally across them.•The strength of this relationship varies across economic, military, andtechnological power.•Some countries deviate from the general pattern.
The Data: Global Power and Economic IndicatorsDataset: Global Power and Economic Indicators•This dataset has 250 observations and combines publicly available datafrom the World Bank Open Data API and the REST Countries API.•The dataset includes indicators of economic, technological, and militarycapacity, as well as a composite measure of national power for countries.•The core variables for this project are:•country•gdp_per_capita•economic_power (GDP × GDP growth)•tech_power (Internet usage × High-tech exports)•military_power (Military spending)•power_index (combination of the power components)•power_rank

Conclusion•Wealth is consistently associated with higher levels of national power, butthe strength of this relationship varies across different dimensions.•Table 2 and Figure 2 suggest that wealth more reliably translates intoeconomic and military capacity than into technological capacity,indicating that GDP per capita operates more as a general enablingresource than a uniform driver of national power.•Outliers such as Monaco and China highlight that state size and strategicpriorities can condition how effectively wealth translates into power.Overall, wealth is a necessary but insufficient foundation for nationalpower; it enables, but does not guarantee, a state’s ability to projectinfluence across economic, military, and technological domains.
