Abstract:	This thesis construct an order-driven artificial stock market base on Daniels et al. (2003) model. We also use autoregressive conditional duration (ACD) model initiated by Engle and Russell (1998) to model duration or order size. We analyzed the transaction cost of ten securities, including stocks, Exchange-Traded Funds (ETFs) and Real Estate Investment Trusts (REITs), in Taiwan stock market and compared this result with the simulated cost of our models. We find that for those frequently traded securities, for example, TSMC (2330.TW) or China Steel (2002.TW), it is better not to incorporate ACD model of duration in the model, and for those not frequently traded securities, for example, President Chain Store (2912.TW) or Gallop No.1 Real Estate Investment Trust Fund (01008T.TW), it is better to incorporate ACD model of duration in the model. Our empirical estimates show that the liquidity costs of market order of these ten securities are generally smaller than 3%, and largely lied between -1% and 1%. We, however, find that simulation costs of market orders in our model, with a range from 0% to 10%, are generally larger than those of real data. One possible reason for this departure is that investors in stock markets generally do not place their orders blindly. They tend to wait for the appearance of opposite order size, and then place their orders. They also tend to split up a large order, and then reduce market impact. These behavior do not exist in our simulation. Regardless of these differences, our models may still be a simulation tool for transaction cost assessment when one would like to liquidate their asset in a short span of time.
