Military spending, measured as a percentage of GDP, serves as a proxy for conflict-related resource allocation, while GDP per capita (constant 2015 USD) represents economic development. Data were obtained from the World Development Indicators (WDI), producing a final dataset of 7,609 country-year observations after cleaning and aligning missing values.</p> <p>Because both variables are continuous, Pearson's correlation analysis was selected to determine the direction, strength, and statistical significance of the relationship. Data preparation and statistical analysis were completed using R. Prior to hypothesis testing, both variables were examined for distributional characteristics and outliers. Military expenditure displayed right-skewness, while GDP per capita reflected the expected distribution associated with global income inequality. Pearson's correlation coefficient, corresponding t-statistic, degrees of freedom, p-value, and 95% confidence interval were subsequently calculated using standard statistical procedures.</p> <h2>Statistical Findings</h2> <p>The analysis identified a weak but statistically significant negative relationship between military expenditure and GDP per capita. The Pearson correlation coefficient was <strong>r = –0.0605</strong>, with a corresponding <strong>t-statistic of –5.289</strong>, <strong>7,607 degrees of freedom</strong>, and a highly significant <strong>p-value of 1.264 × 10<sup>–7</sup></strong>. The 95% confidence interval ranged from <strong>–0.0829</strong> to <strong>–0.0381</strong>, confirming that the relationship was unlikely to have occurred by chance.</p> <p>Although statistically significant, the magnitude of the association was relatively small. Military expenditure explained approximately 0.36% of the variation in GDP per capita, indicating that defence spending alone is not a major determinant of economic development. Nevertheless, the negative direction of the relationship suggests that countries allocating a larger proportion of national resources to military activities generally experience slightly lower levels of economic development.</p> <h2>Interpretation of the Findings</h2> <p>The findings support the theoretical argument that conflict-related expenditure diverts resources away from productive sectors such as education, infrastructure, healthcare, and private investment. While military spending cannot fully capture the complexity of armed conflict, it provides an observable indicator of national priorities during periods of heightened security concerns. The results therefore offer preliminary evidence that sustained military expenditure may be associated with modest reductions in long-term economic performance.</p> <p>The relatively small effect size also suggests that economic development is influenced by numerous additional factors beyond military expenditure, including governance quality, institutional effectiveness, trade openness, political stability, corruption, technological advancement, and natural resource endowment. Consequently, military expenditure should be interpreted as one contributing factor rather than the sole driver of national economic outcomes.</p> <h2>Comparison with Previous Research</h2> <p>The study's findings are consistent with previous research examining the economic consequences of armed conflict. Earlier studies argue that conflict reduces productivity, disrupts investment, limits capital accumulation, and generates economic spillover effects across neighbouring countries. Similarly, previous research has shown that warfare significantly reduces international trade, creating additional barriers to long-term economic growth.</p> <p>Existing literature also emphasizes that the economic burden of military expenditure varies across countries. Lower-income nations often experience greater developmental setbacks because defence spending consumes resources that could otherwise support essential public services and infrastructure. Wealthier countries may be better positioned to absorb these costs without experiencing equally severe economic consequences. These differences may partly explain the relatively weak overall correlation observed within the global sample.</p> <h2>Overall Conclusions</h2> <p>This research provides empirical evidence of a statistically significant negative relationship between military expenditure and economic development across countries between 1988 and 2023. Although the observed relationship is relatively weak, it supports existing theoretical perspectives suggesting that conflict-related expenditure may hinder economic growth by redirecting resources away from productive investment. The findings contribute preliminary evidence to the broader literature on conflict economics and highlight the importance of considering military spending alongside institutional, political, and socioeconomic factors when evaluating long-term development outcomes.</p> <h2>References</h2> <p>References remain exactly as presented in the original document.</p>
