Tedarik Zinciri Baskısı Altında E-Ticaretin Fiyat Dinamikleri: Şok Geçirgenliği Azalıyor Mu?

Abstract

Küresel tedarik zinciri baskılarının arttığı dönemlerde e-ticaret penetrasyonunun fiyat dinamiklerine etkisini inceleyen bu çalışma, perakende e-ticaretin fiyat geçişkenliğini azaltarak bir amortisör işlevi görüp görmediğini analiz etmektedir. Jordà (2005) tarafından önerilen etkileşimli panel yerel projeksiyon yöntemi kullanılarak, bölgesel fiyat yayılımı ölçümleri ile küresel tedarik zinciri şok endekslerini birleştiren özgün bir panel veri seti üzerinde yapılan tahminler, tedarik zinciri şoklarının genel fiyat seviyesini belirgin biçimde artırdığını göstermektedir. Ancak, e-ticaretin yaygın olduğu ortamlarda bu şokların fiyatlara yansıması kısmen zayıflayabilmektedir: E-ticaret payının yüksek olduğu durumlarda tüketici fiyat endeksindeki tepki, düşük e-ticaret ortamına kıyasla Sonuçlar, e-ticaretin sağladığı stoklama ve alternatif tedarik olanakları sayesinde küresel tedarik sıkıntılarının yerel fiyatlara geçişini geciktirebileceğine işaret etmektedir. Bu bulgular, fiyat istikrarı tartışmalarına lojistik kapasitenin rolü bağlamında katkı sunarken, politika yapıcılar için dijital ekonominin enflasyonist şokları yönetmedeki potansiyelini vurgulamaktadır.

E-Commerce Price Dynamics Under Supply Chain Pressure: Does Shock Pass-Through Diminish?

Year 2026, Issue: e-ticaret lojistiği, 65 - 84, 06.03.2026

Abstract

This study investigates whether the rise of retail e-commerce acts as a buffer for price shocks during periods of elevated supply chain pressure. We examine price dynamics using an interactive panel local projection approach (Jordà, 2005) on a unique dataset that combines regional price dispersion measures with global supply chain shock indices. Our findings indicate that global supply chain shocks significantly increase the overall price level (consumer price index). However, the pass-through of these shocks to consumer prices is somewhat attenuated in environments with higher e-commerce penetration: in high e-commerce settings the initial CPI response to a supply shock is more muted compared to low e-commerce contexts, although the difference is modest and not persistent. Moreover, we do not find strong evidence that supply chain disruptions systematically affect price dispersion across regions or products. These results suggest that e-commerce’s price-equalizing effect – via improved inventory management and alternative sourcing – may delay or soften the impact of global supply shocks on local prices. The study contributes to the price stability literature by highlighting the potential of the digital marketplace to mitigate inflationary shocks and offers insights for policymakers regarding the macroeconomic role of e-commerce in shock transmission.
