Uncovering Hedge Fund Skill from the Portfolio Holdings They Hide

Authors
Vikas Agarwal, Wei Jiang, Yuehua Tang, and Baozhong Yang
Date
April 1, 2013
Format
Journal Article
Journal
The Journal of Finance

This paper studies the "confidential holdings" of institutional investors, especially hedge funds, where the quarter-end equity holdings are disclosed with a delay through amendments to Form 13F and are usually excluded from the standard databases. Funds managing large, risky portfolios with nonconventional strategies seek confidentiality more frequently. Stocks in these holdings are disproportionately associated with information-sensitive events or share characteristics indicating greater information asymmetry.

Price Competition under Subsidization: Applications to Medicare Reform

Authors
Awi Federgruen and Lijian Lu
Date
February 6, 2013
Format
Working Paper

We consider price competition models for oligopolistic markets, in which a significant part of the product or service price is paid by a third party, as a subsidy. The consumer is, therefore, impacted by the net price, defined as the difference between the nominal price and the subsidy, while the firms earn the full nominal price, partially paid by the subsidizing third party and the remainder by the consumer.

Journal Article
Journal
Journal of Interactive Marketing

A high quality customer database is a cornerstone of successful interactive marketing strategies and tactics. Based on the notion that customer data quality is not only a technical but also an organizational problem, this study develops and tests an organizational learning framework of the relationship between organizational processes, customer data quality and firm performance. The findings show that high quality customer data impact both customer and business performance and that the most important driver of customer data quality comes from the executive suite.

Strategic Conduct in Credit Derivative Markets

Authors
Patrick Bolton
Date
January 1, 2013
Format
Journal Article
Journal
International Journal of Industrial Organization

This paper reviews recent research at the intersection of industrial organization and corporate finance on credit default swap (CDS) markets. These markets have been at the center of the financial crisis of 2007-2009 and many aspects of their operation are not well understood. The paper covers topics such as counterparty risk in CDS markets, the "empty creditor problem," "naked" CDS positions, the super-senior status of credit (and other) derivatives in Chapter 11 bankruptcy, and strategic behavior in CDS settlement auctions.

The Dynamics of Optimal Risk Sharing

Authors
Patrick Bolton and Christopher Harris
Date
January 1, 2013
Format
Working Paper

We study a dynamic-contracting problem involving risk sharing between two parties — the Proposer and the Responder — who invest in a risky asset until an exogenous but random termination time. In any time period they must invest all their wealth in the risky asset, but they can share the underlying investment and termination risk. When the project ends they consume their final accumulated wealth. The Proposer and the Responder have constant relative risk aversion R and r respectively, with R > r > 0.

Valuing Private Equity

Authors
Neng Wang and Jinqiang Yang
Date
January 1, 2013
Format
Working Paper

We develop a dynamic valuation model of private equity (PE) investments by solving the portfolio-choice problem for a risk-averse investor (LP), who invests in a PE fund, managed by a general partner (GP). Key features are illiquidity, leverage, GP value-adding skills (alpha), and compensation, including management fees and carried interest. We find that the costs of management fees, carried interest, and illiquidity are high, and the GP needs to generate substantial value to cover these costs. Leverage substantially reduces these costs.

Accounting’s Role in the Reporting, Creation, and Avoidance of Systemic Risk in Financial Institutions

Authors

Date

Format
Chapter
Book
The Handbook of Systemic Risk

The financial crisis that erupted in late 2007 has resurfaced debates about the role of accounting and external financial reporting by financial institutions in helping detect or mask systemic risks and in exacerbating or mitigating such risks. The debate has largely focused on the role of fair value accounting, securitization and special purpose entities, off-balance sheet reporting and pro-cyclicality. We consider these and other issues using a single company's published accounts.
