Cream‐Skimming in Financial Markets
研究了投资者在非透明市场中获取信息购买优质资产，导致信息获取过多、金融业攫取超额租金，且道德风险下信息的社会价值与获取量反向变化。
ABSTRACT We propose a model in which investors may choose to acquire costly information that identifies good assets and purchase these assets in opaque (OTC) markets. Uninformed investors access an asset pool that has been cream‐skimmed by informed investors. When the quality composition of assets for sale is fixed, there is too much information acquisition and the financial industry extracts excessive rents. In the presence of moral hazard in origination, the social value of information varies inversely with information acquisition. Low quality origination is associated with large rents in the financial sector. Equilibrium acquisition of information is generically inefficient.
