In this study, we investigate a search model with divisible fiat money in a laboratory setting. In the model, there are multiple equilibria with various money holdings distributions. The purpose of this study is to investigate the behavior of subjects and the efficiency of endogenously determined money holdings distributions and transaction prices in this environment. We find that such endogenizing enhanced the coordination of subjects through monetary exchange. The subjects endogenously reduced the trade friction of monetary exchanges and chose relatively efficient money holdings distributions and transaction prices.
