This paper develops a tractable, dynamic, no-arbitrage model for the pricing of bonds and stocks that are subject to default risk. The model produces the bond pricing equations of the Duffie and Singleton (1999) framework. It is then shown that a particular choice of dividend process,...

This paper develops a tractable, dynamic, arbitrage-free model capable of jointly pricing a cross section of bonds and stocks. The bond pricing portion of the model produces the standard affine term-structure equations. It is then shown that a particular choice of dividend process, characterized...

In this paper we analyze the optimal policy for a risk averse agent who wants to sell a large block of shares of a risky security in the presence of price impact and transactions costs. Our framework reduces to the standard Merton portfolio problem in the absence of any market frictions. Optimal...

Consider an economy in which the underlying security returns follow a linear factor model with constant coeffcients. While portfolios that invest in these securities willin general, have a linear factor structure, it will be one with time-varying coeffcients. However, under certain assumptions...

This paper examines the related questions, of the time-series behavior of expected returns and of return predictability, within the framework of the stock-bond pricing model proposed in Mamaysky (2002). The key advantage of the model-based approach adopted in this paper is that the quantities of...

We propose a dynamic equilibrium model of asset prices and trading volume with heterogeneous agents fixed transactions costs. We show that even small fixed costs can give rise to large "no-trade" regions for each agent's optimal trading policy and a significant illiquidity discount in asset...

In this article I study an economy with irreversible durable investment and investors who consume a durable and a nondurable good. In a general equilibrium setting, these assumptions lead to endogenous variation in the implied risk aversion of investors and in the term structure of interest...

This paper presents a model in which investors cannot remain in the market to trade at all times. As a result, they have an incentive to set up trading firms or financial market intermediaries (FMI's) to take over their portfolio while they engage in other activities. Previous research has...
