Microeconomic Trends And Market Power Dynamics In Romania'S Advertising Industry

The Romanian advertising market has undergone significant transformations over the past decade, driven by the rapid growth of the e-commerce sector and the evolving digital landscape. This study aims at comprehensively analyzing the Romanian advertising market, focusing on the market power dynamics among the main participants: advertisers, publishers, and advertising agencies. By examining aggregated industry-level financial data from the Classification of Activities in the National Economy (CAEN) system, this paper highlights the contrasting growth patterns and economic performance of these sectors. Building on this framework, the study provides a detailed microeconomic assessment of structural shifts occurring within Romania's digital media ecosystem. The results reveal a strong expansion of advertising demand, primarily generated by the e-commerce sector, alongside a stagnation of revenues and increasing market concentration within the publishing industry. Despite improved profitability among surviving publishers, their relative bargaining power continues to erode, particularly in relation to large advertisers and dominant international ad-intermediation platforms. The analysis further uncovers substantial asymmetries in economic power across the three sectors, with advertising agencies demonstrating robust financial performance and sustained profitability, while local publishers remain structurally disadvantaged. These imbalances are reinforced by high levels of concentration in both the publishing and ad-tech segments, amplifying competitive distortions and limiting the capacity of domestic media firms to capture the benefits of overall market growth. The paper concludes that without targeted regulatory and strategic interventions, the current market configuration threatens the long-term sustainability, competitiveness, and informational plurality of Romania's digital media environment.
