Commentary: Welcome to the machine
As technology disrupts industry after industry, it is logical to expect the hedge fund industry will be similarly disrupted. We pose the question: How will that disruption happen and where will it come from?

The PFS encourages the creation, translation, and dissemination of research from cross-disciplinary faculty members by hosting faculty research talks; coordinating access to computing and data resources; providing research support and assistance to affiliated faculty; disseminating research to the broader community through the PFS Newsletter; and overseeing fellowships and grants.
The MSFE educates the next generation of industry leaders, ready to apply their quantitative training to solve real-world problems in the finance industry. Together, the research and educational missions of the PFS allow us to foster important interactions with industry partners, involving both the sharing of research & ideas, as well as student recruitment.

How do different bankruptcy approaches affect the local economy? Using U.S. Census microdata, we explore the spillover effects of reorganization and liquidation on geographically proximate firms. We exploit the random assignment of bankruptcy judges as a source of exogenous variation in the probability of liquidation. We find that employment declines substantially in the immediate neighborhood of the liquidated establishments, relative to reorganized establishments.
Recent evidence suggests that investors are inattentive to their portfolios and hire expensive portfolio managers. This paper develops a life-cycle portfolio-choice model in which the investor experiences loss-averse utility over news and can ignore his portfolio. In such a model, the investor prefers to ignore and not rebalance his portfolio most of the time because he dislikes bad news more than he likes good news such that expected news cause a first-order decrease in utility.
We have titled this paper with an ode to a compilation album by a band that was founded in Palo Alto and developed a counter-culture. Though the title espouses a new state of mind, it is investment, not consumption driven, as this is 2017 and not 1965.
We provide a framework for identifying accounting numbers that indicate risk and expected return. Under specified accounting conditions for measuring earnings and book value, book-to-price (B/P) indicates expected returns, providing justification for B/P in asset pricing models. However, the framework also points to earnings-to-price (E/P) as a risk characteristic. Indeed, E/P, rather than B/P, is the relevant characteristic when there is no expected earnings growth, but the weight shifts to B/P with growth.
We investigate the effectiveness of regulatory oversight exercised by the SEC against auditors over the years 1996–2009. The evidence suggests that the SEC is significantly less likely to name a Big N auditor as a defendant, after controlling for both the severity of the violation and for the characteristics of companies more likely to be audited by Big N auditors. Further, when the SEC does charge Big N auditors, the SEC (i) is less likely to impose harsher penalties on the Big N; and (ii) is less likely to name a Big N audit firm relative to individual Big N partners.
We investigate the implementation of a 2014 Government of India mandate that requires companies to at least spend 2% of their profits on corporate social responsibility (CSR) activities. Firms that voluntarily engaged in CSR before the mandate reduce their spending significantly down to the suggested 2% level. Firms that did not actively engage in CSR before the mandate increase their spending marginally. CSR spending post mandate is highly sensitive to negative shocks to firm profits, but not to positive profit shocks.
This study develops a timely and unbiased measure of expected credit losses. The expected rate of credit losses (ExpectedRCL) is a linear combination of various non-discretionary credit risk-related measures disclosed by banks. ExpectedRCL performs substantially better than net charge-offs, realized credit losses, and fair value of loans in predicting credit losses, and reflects all the explanatory power of the credit loss-related information in these variables.
We examine the cost-effectiveness, from the shareholders' perspective, of the accounting standards issued by the FASB during 1973-2009. We evaluate (i) the stock market reactions of firms affected by the standards surrounding events that changed the standard's probability of issuance; and (ii) whether the market reactions are related, in the cross-section, to agency problems, information asymmetry, proprietary costs, contracting costs, and changes in estimation risk.

Dates: January 1, 2018 - June 30, 2022
Coordinated by Program for Financial Studies Academic Board Member and current Senior Vice Dean, Charles Jones, Norges Bank has awarded Columbia Business School a 3-year international study of the effect of technological and regulatory changes, across equity and fixed income markets, in both the US and Europe, on market transparency. Technological and business innovations are changing the ability of market participants to observe information about the trading process, and planned regulatory changes in both the US and Europe will significantly change the information available to traders. The main goal is to identify the effects of these various regulatory changes and innovations on market quality and liquidity, and to provide guidance to policymakers and market participants on how to improve market design.
Transparency: At What Speed and Cost? One-day market structure conference hosted on June 14, 2018 in NYC bringing together academics, regulators and practitioners. A second U.S.-based conference was hosted on October 29, 2021 virtually.
Dates: 2011 - 2014
The Network for Studies on Pensions, Aging and Retirement (NETSPAR) has awarded a competitive three-year international grant to a group of researchers at Columbia Business School. Coordinated by Program for Financial Studies Academic Board Member Andrew Ang and also involving professors Geert Bekaert, Robert Hodrick, Morten Sorensen, and Steve Zeldes, the research agenda is “Aspects of Long Horizon, Illiquidity, and Non-Linear Tail Risk for Portfolio Strategies.” This research exemplifies the link between theory and practice, advancing academic scholarship with direct and significant policy implications in the areas of asset pricing, asset allocation, risk management, and pension valuation and design.
