Abstract: Traditional finance theory generally assumes a frictionless market, in which a risk premium is described only by price volatility. In reality, however, the risk premium is influenced by a range of factors including the market microstructure. This paper constructs a novel no- arbitrage and complete model that explicitly incorporates among the market microstructure factors a constraint on a finite number of securities issued. From the theoretical perspective, the model is a synthesis of market microstructure and mathematical finance in that it makes it possible to derive a risk-neutral price applicable to a market with a detailed market microstructure. We also calibrate the model to show that the price in the Japanese government bond futures market is significantly affected by the factor of number of securities issued.
