In a market with price-impact proportional to a power of the order flow, we find optimal trading policies and their implied performance for long-term investors who have constant relative risk aversion and trade a safe asset and a risky asset following geometric Brownian motion. These quantities...

We consider a market consisting of one safe and one risky asset, which offer constant investment opportunities. Taking into account both proportional transaction costs and linear price impact, we derive optimal rebalancing policies for representative investors with constant relative risk...

We study the portfolio selection problem of banks which account for fire-sale spillovers. Our analysis highlights the fundamental trade-off between diversification at the individual and systemic level. While sacrificing individual diversification benefits to reduce portfolio commonality...

I study the general equilibrium of a pure-exchange economy with several agents who receive uninsurable income, trade a dividend-paying stock, and borrow from and lend to each other. Agents are heterogeneous in risk-aversion and time-preference, and hold differing beliefs on the growth rates of...
