BOOKBUILDING AND FIXED-PRICE OFFERINGS: EVALUATING PRICING EFFICIENCY IN TRANSITION ECONOMIES

Abstract

This study evaluates the comparative pricing efficiency of dynamic bookbuilding versus traditional fixed-price allocation mechanisms in Initial Public Offerings (IPOs) within transition and emerging capital markets. Grounded in information revelation theory and the economics of asymmetric information, the paper examines how the structural choice of issuance architecture influences primary pricing accuracy, the magnitude of initial underpricing, and sovereign divestiture proceeds. The analysis demonstrates that while dynamic bookbuilding theoretically optimizes price discovery by extracting private institutional valuation signals, its pricing efficiency in transition environments is frequently constrained by shallow domestic institutional depth, illiquid secondary trading, and underwriter agency frictions. Conversely, fixed-price mechanisms-historically favored in early privatization phases-suffer from rigid valuation benchmarks and severe adverse selection, precipitating excessive underpricing or costly undersubscription. The study advocates for an institutionalized hybrid allocation framework that pairs dynamic institutional bookbuilding with formulaic retail tranches, supported by algorithmic allocation audits and enhanced regulatory oversight to foster long-term secondary market stability.
