We analyze the effects of the observed increased share of delegated capital for trading strategies and equilibrium prices by introducing delegation into a standard Lucas exchange economy. In equilibrium, some investors trade on their own account, but others decide to delegate trading to...

I allow trading horizon heterogeneity across groups in a standard differential information model of a financial market. This approach can explain the well-established phenomenon that, after a public announcement, trading volume increases, more private information is incorporated into prices and...

We analyze the effects of the observed increased share of delegated capital for trading strategies and equilibrium prices. We introduce delegation into a standard Lucas exchange economy, where in equilibrium some investors trade on their own account, but others decide to delegate trading to...

This paper uncovers the changes in the cross-sectional distribution of idiosyncratic volatility of stocks over the period 1963--2008. The contribution of the top decile to the total market idiosyncratic volatility increased, while the contribution of the bottom decile decreased. We introduce a...

We propose a model of delegated portfolio management with career concerns. Investors hire fund managers to invest their capital either in risky bonds or in riskless assets. Some managers have superior information on the default risk. Looking at the past performance, investors update beliefs on...

I allow heterogenity in trading horizons across groups in a standard differential information model of a financial market. This can explain the empirical facts that after public announcements trading volume increases, more private information is incorporated into prices and volatility increases....

Polarization of opinions after public announcement is widely observed, but often considered to be inconsistent with Bayesian learning. I show that this is not the case in environments where higher-order expectations play a role. I characterize informational structures where public announcement...

We develop a dynamic model of liquidity provision, in which hedgers can trade multiple risky assets with arbitrageurs. We compute the equilibrium in closed form when arbitrageurs' utility over consumption is logarithmic or risk-neutral with a non-negativity constraint. Liquidity is increasing in...
