We study the impact of ambiguity on financial intermediation in an economy where agents have random liquidity needs. The ambiguity the agents face is modeled by the degree of confidence in their additive beliefs. We compare an optimal liquidity allocation with the allocation achieved by trade in...

We find that active mutual funds perform better after trading more. This time-series relation between a fund’s turnover and its subsequent benchmark-adjusted return is especially strong for small, high-fee funds. These results are consistent with high-fee funds having greater skill to identify...

Financial market liquidity has become increasingly fragmented across multiple trading platforms. We propose an intuitive welfare-based market quality metric that can properly aggregate local market conditions across both securities and trading venues. Our analysis rests on a general equilibrium...

This paper shows that the finance and growth relationship is as important in resource-based economies as in other economies. This paper also documents less developed financial systems in resource-based economies and banks that are more liquid, better capitalized and more profitable, but give...

We introduce two subclasses of convex measures of risk, referred to as entropy coherent and entropy convex measures of risk. We prove that convex, entropy convex and entropy coherent measures of risk emerge as certainty equivalents under variational, homothetic and multiple priors preferences,...

We propose a model in which firms involved in trading securities overinvest in financial expertise. Intermediaries or traders in the model meet and bargain over a financial asset. As in the bargaining model in Dang (2008), counterparties endogenously decide whether to acquire information, and...

We present a dynamic microstructure model where a dealer market (DM) and a crossing network (CN) interact. Sequentially arriving agents with different valuations for an asset maximize their profits either by trading at a DM or by submitting an order for (possibly) uncertain execution at a CN. We...
