Far More Than a Shot in the Arm: Vaccines and Consumer Spending

Summary

1. Background and Objective
This paper investigates the impact of the COVID-19 vaccination rollout on consumer spending dynamics in Estonia, Latvia, and Lithuania, using daily debit and credit card transaction data. The study empirically examines how vaccination, along with policy interventions, shaped household consumption patterns.

2. Key Findings
📊 Effect of Vaccination

• A 1% increase in COVID-19 vaccination numbers is associated with a 0.011% improvement in debit and credit card transactions, indicating a statistically and economically significant positive effect on consumer spending.
• This effect remains robust even after controlling for other policy responses, such as lockdown measures and economic support packages.

🔍 Heterogeneity in Spending Patterns

• The post-vaccination boost in spending is observed more prominently in contact-intensive sectors (e.g., services) compared to goods, reflecting induced behavioral shifts due to reduced pandemic risk.
• A granularity analysis of 33 spending categories reveals that sectors directly restricted during lockdowns (e.g., travel, dining) exhibit stronger responsiveness to vaccination efforts.

📈 Policy Implications

• Faster vaccine rollouts correlate with quicker stabilization of consumption, underscoring the role of vaccines in boosting consumer confidence and accelerating post-pandemic recovery.
• Complementary measures—targeted containment policies and well-designed economic support—are crucial to mitigate pandemic-induced disruptions.

3. Methodology

• Data from 2020 to 2022 was used, including daily transaction data, COVID-19 case/death/vaccination metrics, and OxCGRT policy indices.
• Econometric analysis employs System GMM (Generalized Method of Moments) to address endogeneity and dynamic effects, confirming persistent impacts of both infections/vaccinations on consumption.

4. Granular Breakdown

• The study provides a nuanced analysis of consumption subcategories, highlighting that the induced behavioral changes—such as a partial shift from cash to card payments—are also influenced by broader pandemic fatigue factors.
