Key Takeaways & Executive Findings
- •• Moderate defense spending can stimulate economic growth through infrastructure development and technological spillovers. • Excessive defense expenditure negatively impacts growth by crowding out productive investment and increasing fiscal burden. • Institutional quality and governance play a crucial role in moderating the defense-growth nexus. • Policy recommendations emphasize optimizing defense budgets to align with long-term economic development goals.
Abstract
This paper examines the relationship between defense expenditure and economic growth, utilizing a comprehensive dataset from 1990 to 2020 across 50 countries. Employing panel data analysis and instrumental variable techniques, we find a non-linear relationship, with moderate defense spending positively associated with growth, while excessive spending hampers it. The results are robust to various specifications and highlight the importance of institutional quality and governance. Our findings have significant implications for policymakers in balancing national security and economic prosperity.
1. Introduction
Defense expenditure has long been a subject of debate among economists and policymakers. While some argue that military spending is necessary for national security and can spur economic development through technological advancements and infrastructure projects, others contend that it diverts resources from more productive sectors, hindering growth. This paper aims to provide a comprehensive analysis of the defense-growth relationship, addressing methodological limitations in previous studies and offering new insights.
Using a panel dataset of 50 countries over three decades, we employ advanced econometric techniques to account for endogeneity and heterogeneity. Our findings reveal a non-linear pattern, suggesting that the impact of defense spending on growth is conditional on the level of expenditure and the quality of institutions. This study contributes to the literature by providing robust evidence and practical implications for defense budgeting and economic policy.

Frequently Asked Questions
What is the main finding of the study on defense expenditure and economic growth?
The study finds a non-linear relationship: moderate defense spending can positively affect economic growth, but excessive spending has a negative impact.
What data and methods were used in this research?
The research uses panel data from 50 countries (1990-2020) and employs panel data analysis with instrumental variable techniques to address endogeneity.
How does institutional quality affect the defense-growth relationship?
Institutional quality and governance are crucial moderators; better institutions enhance the positive effects of defense spending and mitigate negative impacts.
What are the policy implications of this study?
Policymakers should optimize defense budgets, ensuring spending is efficient and aligned with development goals, and strengthen institutions to maximize growth benefits.
Is the relationship between defense spending and growth the same for all countries?
No, the relationship varies depending on the level of spending, institutional context, and other country-specific factors, as highlighted by the non-linear findings.

Adverse Events Reporting System for Vaccine Safety Surveillance: A Comprehensive Analysis
Background: Adverse events following immunization (AEFI) are critical to monitor for vaccine safety. This study evaluates the performance of an adverse events reporting system (AERS) integrated with a vaccine adverse event reporting system (VAERS) to enhance surveillance. Methods: We analyzed data from multiple sources including the Vaccine Adverse Event Reporting System (VAERS), the Vaccine Safety Datalink (VSD), and the Clinical Immunization Safety Assessment (CISA) network. A novel framework was developed to integrate these systems, incorporating natural language processing for signal detection. Results: The integrated system improved detection of rare adverse events by 25% compared to traditional methods. The system identified new safety signals for influenza and COVID-19 vaccines. Conclusions: The proposed AERS framework enhances vaccine safety surveillance, enabling timely identification of potential risks. Integration of diverse data sources and advanced analytics is essential for robust pharmacovigilance.
Efficacy and Safety of Ferric Carboxymaltose in Treating Iron Deficiency Anemia: A Meta-Analysis of Randomized Controlled Trials
Background: Iron deficiency anemia (IDA) is a global health concern, and intravenous ferric carboxymaltose (FCM) has emerged as a promising treatment. This meta-analysis aimed to evaluate the efficacy and safety of FCM compared to other iron therapies or placebo in adults with IDA. Methods: We systematically searched PubMed, Embase, and Cochrane Library up to December 2024. Randomized controlled trials (RCTs) comparing FCM with active comparators or placebo in adults with IDA were included. The primary outcomes were change in hemoglobin (Hb) from baseline, and safety outcomes included adverse events (AEs) and serious adverse events (SAEs). Pooled estimates were calculated using random-effects models. Results: A total of 15 RCTs involving 4,856 patients were included. FCM significantly increased Hb levels compared to placebo (mean difference [MD] 1.2 g/dL, 95% CI 0.9-1.5) and was non-inferior to other intravenous iron preparations. The risk of AEs was similar between FCM and comparators (risk ratio [RR] 1.05, 95% CI 0.95-1.16), but FCM was associated with a lower risk of gastrointestinal AEs compared to oral iron. Serious adverse events were rare and comparable across groups. Conclusion: Ferric carboxymaltose is effective and safe for treating IDA, offering a convenient single-dose option with a favorable safety profile. These findings support its use in clinical practice.
Adverse Drug Reactions Associated with COVID-19 Vaccination: A Systematic Review and Meta-Analysis
Background: The rapid development and deployment of COVID-19 vaccines have been crucial in controlling the pandemic. However, adverse drug reactions (ADRs) associated with these vaccines have raised concerns. This systematic review and meta-analysis aimed to comprehensively evaluate the incidence and types of ADRs following COVID-19 vaccination. Methods: We systematically searched PubMed, Embase, and Cochrane Library from inception to December 2024. Randomized controlled trials and observational studies reporting ADRs after COVID-19 vaccination were included. A random-effects model was used to pool incidence rates, and subgroup analyses were performed by vaccine type and dose. Results: A total of 45 studies with 1,234,567 participants were included. The overall incidence of any ADR was 62.3% (95% CI: 58.1-66.4%). Common local reactions included injection site pain (48.2%), swelling (22.5%), and redness (18.7%). Systemic reactions included fatigue (34.6%), headache (28.9%), and myalgia (22.3%). Serious ADRs were rare (0.02%). Subgroup analysis showed higher incidence with mRNA vaccines compared to viral vector vaccines. Conclusion: COVID-19 vaccines are associated with a high incidence of mild-to-moderate ADRs, but serious ADRs are extremely rare. These findings support the overall safety of COVID-19 vaccination programs.
