The Transformation of Broadband Demand: From Discretionary Service to Essential Infrastructure (2010-2024)

TL;DR

This paper analyzes broadband price elasticity across 33 European countries from 2010 to 2024 using two-way fixed effects and Driscoll–Kraay standard errors. It uncovers a decade-long transformation: EaP markets exhibit strong pre-COVID elasticity ($ ext{EaP}\varepsilon oughly -0.61$) that collapses to near zero by 2020–2024, while EU markets move from $ ext{EU}\varepsilon oughly -0.12$ to near zero as well. Crucially, placebo tests show the EaP trend began around 2015, indicating secular digital integration rather than a COVID-19 shock as the primary driver; price measurement matters, with income-relative prices delivering robust results across specifications. The findings imply a policy shift from affordability subsidies toward universal infrastructure deployment and quality improvements as broadband becomes an essential utility with diminishing price responsiveness.

Abstract

Has broadband become a necessity good immune to price changes? Using a 15-year panel of 33 European countries (2010--2024) and two-way fixed effects with Driscoll--Kraay standard errors, we document a fundamental transformation in broadband demand. Pre-COVID, Eastern Partnership countries exhibited highly elastic demand ($\varepsilon = -0.61$, p$<$0.001) -- a 10\% price reduction increased subscriptions by 6\% -- while EU countries showed moderate elasticity ($\varepsilon = -0.12$, p$<$0.05). By 2020--2024, both regions converged to near-zero elasticity, with price changes having no detectable effect on adoption. Crucially, placebo tests reveal this transformation began in 2015, not 2020, indicating a decade-long digital integration process rather than a COVID-19 shock. We further demonstrate that price measurement critically affects inference: income-relative prices (as \% of GNI) yield significant results in 100\% of specifications, compared to only 25\% for PPP-adjusted prices. These findings have immediate policy relevance: as broadband transitions from discretionary service to essential utility, policy emphasis must shift from affordability subsidies to universal infrastructure deployment.

• Figure 1: Robustness of price elasticity across control specifications (pre-COVID, 2010--2019). EaP elasticity is significant at p$<$0.01 in all specifications ($-0.58$ to $-0.63$). EU elasticity ranges from $-0.09$ to $-0.14$. Error bars show $\pm$1 Driscoll--Kraay SE.
• Figure 2: Disappearance of price elasticity during COVID-19. Pre-COVID elasticities are significantly negative (EU: $-0.12$**, EaP: $-0.61$***), while COVID-era elasticities are statistically insignificant. Both shifts are significant at p$<$0.005. Error bars show $\pm$1 Driscoll--Kraay SE.
• Figure 3: Temporal evolution of broadband price elasticity (2015--2024). Year-by-year estimates using 2010--2014 as reference. Filled markers indicate p$<$0.10; open markers indicate non-significance. Shaded region marks the COVID period (2020--2024). Both regions show gradual decline starting around 2015, validating the structural transformation hypothesis.
• Figure 4: Placebo test for pre-COVID trends. (a) Three-phase evolution of elasticity showing the pre-COVID trend for EaP. (b) Placebo coefficients: EU effect is insignificant (p$=$0.31, no pre-trend); EaP effect is significant (p$=$0.045, pre-trend exists). This validates the gradual transformation hypothesis.
• Figure 5: EaP elasticity across 24 specifications (8 controls $\times$ 3 price measures, pre-COVID). Darker shading indicates stronger negative elasticity. Significance: ***p$<$0.01, **p$<$0.05, *p$<$0.10. Range: $-0.52$ to $-0.68$, demonstrating robustness to modeling choices.
