In credit markets, asymmetric information problems arise when borrowers have private information about their creditworthiness that is not observable by lenders. If these informational asymmetries do not negatively affect lenders' profitability, then they are irrelevant to lenders.

The paper analyzes the effects of informational asymmetries on the market structure of the banking industry in a multi-period model of spatial competition. All lenders face uncertainty with regard to borrowers’ creditworthiness, but, in the process of lending, incumbent banks gather proprietary information about their clients, acquiring an advantage over potential entrants. These informational asymmetries are an important determinant of the industry structure and may represent a barrier to entry for new banks. The paper shows that, in contrast with traditional models of horizontal differentiation, the steady-state equilibrium is characterized by a finite number of banks even in the absence of fixed costs.

In Exchange-Traded Funds and the New Dynamics of Investing, Ananth Madhavan examines the quiet transformation of asset management through the rise of passive or index investing. A closely-related phenomenon is the rise of exchange-traded funds (ETFs). An ETF is an investment vehicle that trades intraday and seeks to replicate the performance of a specific index. ETFs have grown substantially in size, diversity, and market significance in recent years. These trends have generated considerable interest, especially from retail and institutional investors and increasingly from academics, regulators and the press. ETFs have the power to be a disruptive innovation to today's asset management industry because many traditional active managers and hedge funds deliver a significant fraction of their active returns via static exposures to factors like value. Indeed, for the first time ever, assets in global ETFs exceeded $3 trillion in 2015, passing the amount in hedge funds.
