In this paper, we propose an innovative VIX model which takes future market information available to the traders into account. The future information is modeled by an initially enlarged filtration in our setup. We derive an explicit representation for the anticipative VIX process and obtain the...

Given a market with a price process S populated by heterogeneous traders with differential information, beliefs, and trading constraints, let the smallest information set containing all of the traders' information be denoted F. This market is defined to be informationally efficient (Fama [2])...

We present comprehensive evidence in support of giving liquidity equal standing to size, value/growth, and momentum as investment styles, as defined by Sharpe (1992). First, we show that financial market liquidity, as identified by stock turnover, is an economically significant indicator of...

This brief paper constructs a model of delegated portfolio management in which two agency relationships are characterized. First, a delegation process from investors to fund companies, and second, a delegation from fund companies to fund managers. Career concerns of both agents lead to a...

The capital structure arbitrage strategy exploits the discrepancies between the credit default swap and equity markets. It assumes that both markets instantaneously react to new information, so it fails to take into account the lead-lag relationships between the prices in the two markets and...

In this paper we survey the theoretical and empirical literature on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how illiquidity...

This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced — or has failed to influence — federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH...

This paper provides a first step in developing a system-wide stress simulation. The model incorporates several important features of the financial system. These include several types of institution (including banks and non-banks) and how their actions may propagate and amplify stress. Rather...
