The effect of the transparency of order flows in a dealer market with several securities

This paper compares two trading mechanisms in a dealer market with several securities exhibiting asymmetric information and imperfect competition, These two market structures differ in the information received by market-makers. While in the first of them when setting the price of an asset, they observe the order flows of all assets, in the second one they only observe the order flow corresponding to this asset. In order to make this comparison, we analyze several market indicators such as the informed expected traded volume, the market depth, the volatility and the informativeness of equilibrium prices, and the informed traders' ex-ante expected profits.
