Abstract: This paper develops a theoretical analysis of share market price formation driven by accounting and market structures. Heterogeneous investors are assumed to discover and process fundamental information disclosed by accounting system of share-issuing entity. Information set available to share market investors for decision-making comprises then market-driven and firm-specific (non-market) information. On the one side, accounting system provides collective signal of fundamental information; on the other side, price system provides collective signal of market-driven information over time. Both jointly drive the formation of aggregate share market prices through limited knowledge, hazard, and social interaction. Numerical simulations are provided under alternative accounting designs (namely, historical cost and fair value accounting regimes), to derive implications and recommendations for the concept and occurrence of speculative bubbles and herd behavior; the cyclical effects of accounting regime on share market dynamics; and the “value relevance” of accounting information and its role in the formation of share market prices over time. This numerical statistical analysis contributes to shed light on accounting anomalies and fundamental analysis. Copyright Springer-Verlag Berlin Heidelberg 2015
