We present a simple, Glosten-Milgrom type equilibrium model to analyze the decision of informed traders on whether to use limit or market orders. We show that even after incorporating an order's price impact, not only may informed traders prefer to use limit orders, but the probability that they...

Retirement flexibility and inability to borrow against future labor income can significantly affect optimal consumption and investment. With voluntary retirement, there exists an optimal wealth-towage ratio threshold for retirement and human capital correlates negatively with the stock market...

Transactions, market orders and limit orders are three major factors which affect a specialist's information set and her inventory position. In modeling a specialist's quote updating process, before any exclusion of any of these factors, one should first address the fundamental question of their...

We examine the intertemporal optimal consumption and investmentproblem in a continuous-time economy with a divisible durable good. Consumption services are assumed to be proportional to the stock of the good held and adjustment of the stock is costly, in that it involves the payment of a...

We study the dynamic investment and reporting problem of a Financial institution subject to capital requirements based on self-reported VaR estimates, as in the Basel Committee's Internal Models Approach (IMA). We characterize the solution of this problem using martingale duality and parametric...

Most existing portfolio choice models ignore the prevalent periodic market closure and the fact that market volatility is significantly higher during trading periods. We find that market closure and the volatility difference across trading and nontrading periods significantly change optimal...

In this paper, we use a simple model to illustrate that the existence of a large, negative wealth shock and insufficient insurance against such a shock can potentially explain both the limited stock market participation puzzle and the low-consumption-high-savings puzzle that are widely...

Most existing portfolio choice models ignore periodic market closure and the fact that market volatility is significantly higher during trading periods. We show that market closure and the volatility difference across trading and nontrading periods significantly change optimal trading strategies...

Costly information acquisition makes it rational for investors to obtain important economic news only with limited frequency or limited accuracy. We show that this rational inattention to important news may make investors overinvest or underinvest. In addition, the optimal trading strategy is...
