Summary of "E-Commerce During COVID in Spain: One 'Click' Does Not Fit All"

Core Content

This IMF Working Paper analyzes the impact of the COVID-19 pandemic on e-commerce behavior in Spain, focusing on the heterogeneity in consumer responses across different demographic groups. The study uses a unique proprietary dataset of individual credit card transactions from BBVA to examine how e-commerce spending evolved during the pandemic and its aftermath.

Main Findings

• E-commerce Boom and Reversion:
  The share of e-commerce in total credit-card spending in Spain increased significantly during the pandemic, peaking at around 10% in June 2020. However, this increase was temporary, and the share reverted to pre-pandemic levels by the beginning of 2024.

• Demographic Heterogeneity:
  Different demographic groups exhibited varied responses to the pandemic:

  • Women: Had a higher e-commerce share compared to men, and this gap widened during and after the pandemic.
  • Youth (<35 years): Showed the highest increase in e-commerce usage, both in absolute terms and relative to pre-pandemic trends.
  • Urban Consumers: Used e-commerce more than rural consumers, especially for services.
  • Age Groups: Younger age cohorts (under 35) and the 35–45 group experienced a significant acceleration in e-commerce usage post-pandemic, while older groups (45–55, 55–65, >65) returned to levels below pre-pandemic trends.

• Sectoral Differences:
  E-commerce usage varied across consumption categories:

  • Essential Goods: Such as food and health products saw temporary spikes during lockdowns but returned to pre-pandemic levels.
  • Textiles and Footwear: Experienced a more permanent increase in e-commerce share, doubling from 10% in 2020 to 35% by 2024.
  • Transport and Communication: Sectors like transport saw a sharp decline during lockdowns but gradually recovered. Communication maintained a secular upward trend.
  • Recreation & Culture: Continued its pre-pandemic growth, with temporary spikes aligned with pandemic surges.
  • Restaurants and Hotels: Initially had low e-commerce shares, but saw a temporary boost during lockdowns, which later reverted.

• Behavioral Theories Tested:
  The study tests several theories about consumer behavior during the pandemic:

  • Protection Motivation Theory: Suggests that perceived risk levels influence shopping preferences. While this may have influenced some behavior, it was not the main driver of long-term e-commerce trends.
  • Hoarding Behavior: Some consumers panicked and hoarded goods, but this did not translate into sustained e-commerce growth.
  • Learning by Locking: The paper supports the idea that some consumers, particularly those with lower pre-pandemic e-commerce usage, adopted online shopping permanently due to increased exposure and convenience during lockdowns.

• Methodology:
  The study uses a detailed individual-level dataset from BBVA, tracking 1,000 active clients from January 2017 to December 2022. It includes:

  • Credit and debit card transactions
  • Direct debits and transfers
  • Cash withdrawals
  • Data on sociodemographic characteristics (age, gender, urban/rural location)
  • COICOP (Classification of Individual Consumption by Purpose) and NACE (European Community Economic Activities Classification) to categorize spending

  The dataset is weighted to reflect the Spanish adult population in terms of gender, age, and income.

Key Information

• Data Source: BBVA's proprietary financial transaction database.

• Sample Size: 1,000 active clients, with over 1.8 million transactions.

• Time Period: January 2017 to December 2022, with macro trends extended to January 2024.

• Payment Methods:

  • 40% from card transactions (30% physical, 10% online)
  • 21% from cash
  • 39% from transfers and direct debits

• E-commerce Definition: Transactions where the cardholder and card are not physically present (online purchases, telephone payments, mail-order).

• E-commerce Share Calculation:
  For an individual $i$ at time $t$, the e-commerce share $s_{i,t}$ is calculated as:
  $$
  s_{i,t} = \frac{Total Online Spending_{i,t}}{Total Consumption Spending_{i,t}}
  $$
  For a specific consumption category $j$, it is:
  $$
  s_{i,j,t} = \frac{Total Online Spending by Category_{i,j,t}}{Total Consumption by Category_{i,j,t}}
  $$

• Empirical Methodology:
  The paper estimates the following model:
  $$
  os_{i,r,s,t} = Male_i + Urban_i + Age_i + \overline{os}{s,2019} + Lockdown{r,t} + \alpha_s + \beta_r + \gamma_t + \delta_i + \varepsilon_{i,r,s,t}
  $$
  Additional specifications include interactions between lockdown measures and demographic characteristics to assess behavioral changes.

• Conclusion:
  The paper highlights that while the overall e-commerce share reverted to pre-pandemic levels, certain demographic groups (especially younger and female consumers) adopted online shopping more permanently. The study underscores the importance of using real-time, detailed transaction data to better understand consumption patterns during crises and to complement traditional survey-based methods.

Implications

The findings suggest that the shift to e-commerce during the pandemic was not uniform across all consumer groups. The concept of "learning by locking" appears to explain the long-term behavioral changes observed in some segments. This has important implications for policy and business strategies, as it indicates that not all consumers will continue to use e-commerce at the same rate post-pandemic.
