Sustainability reporting: The role of “Search”, “Experience” and “Credence” information

Corporate sustainability reporting quality has been frequently criticised as being unbalanced, presenting an overly positive view or failing to address material issues. The purpose of this article is to provide a fresh explanation for poor quality sustainability reporting and to propose how quality issues may be addressed. The theoretical framework combines the legitimacy and accountability perspectives using Akerlof's (1970) Market for Lemons theory. Akerlof's approach is extended by differentiating between three types of information in sustainability reports namely search, experience and credence. The article concludes that the type of information must be considered when determining measures to improve report quality.     

Hedge funds,CDOs and the financial crisis: An empirical investigation of the “Magnetar trade”

The so called Magnetar trade (a kind of capital structure arbitrage on the US housing market, using CDS and synthetic CDOs, and exploiting rating-dependent mispricing of risk) has gained a high publicity due to a Pulitzer Prize awarded media story from two journalists of ProPublica (an online news outlet). The story essentially claimed that the mortgage investment strategy of the hedge fund Magnetar during the period between 2006 and mid 2007 was based on a desire to construct CDO deals with riskier assets so that they could place bets that portions of their own deals would fail. This paper provides several pieces of evidence in line with the argument that tranches from Magnetar-sponsored CDOs present overly risky investments. However, investors and rating agencies appear to have adjusted their required spread levels and ratings to reflect this higher riskiness, at least to some extent.     

Accounting “Boot Camp”

This study examines the effectiveness of a program designed to set appropriate student expectations and motivate students to put forth the necessary effort to succeed in intermediate accounting and other upper-division accounting courses. At a mid-sized public university in the Western US many students enrolled in Intermediate Accounting I (their first upper-division course) struggle with the rigor and academic demands of this course, resulting in failure rates of 30–45%. In many cases, students new to upper-division courses appear to lack a commitment to, or awareness of, the effort needed for success in the accounting program. The faculty implemented an accounting “Boot Camp” to prepare new accounting majors for the expectations of the program. This paper details the implementation of the Boot Camp and reviews its effectiveness by comparing the performance of attendees with the performance of non-attendees. After controlling for other contributing factors, the evidence suggests that attendees outperform their non-attending peers in Intermediate Accounting I. This relatively low-cost intervention should be attractive to faculty concerned about the common problem of students failing and then retaking intermediate accounting.     

An alternative measure of the “world market portfolio”: Determinants, efficiency, and information content

The world market portfolio plays an important role in international asset pricing, but is unobservable in practice. We first propose a framework for constructing a market proxy that corresponds to the “market portfolio” of financial theory. We then construct this proxy, analyze its determinants and test its efficiency and explanatory power over the period 1975-2007 with respect to the return generating processes of a broad asset universe. We show that its major determinants are traded assets and that it is not efficient. However, it is significant for explaining individual asset returns over an asset universe that includes stocks, bonds, money markets and commodities. The explanatory information is incremental to what is available in traded asset prices and the significance of this information is robust with respect to diversified portfolios generated by factor analysis and to characteristic-sorted portfolios as well as to various model specifications, including the single-index model, the Fama-French (1992) three factor model for stocks, and various specifications of multi-index models hedged and unhedged for foreign currency risk.     

An alternative interpretation of the discontinuity in earnings distributions

We show that the asymmetric effects of income taxes and special items for profit and loss firms contribute to a discontinuity at zero in the distribution of earnings. Income taxes draw profit observations towards zero while negative special items pull loss observations away from zero. These earnings components are thus expected to contribute to a discontinuity even in the absence of discretion. We show our results are not an artifact of deflation and that other common components of earnings do not have similar effects on the earnings distribution around zero.

“Every today was a tomorrow”: An integral method for indexing the social mediation of preferred futures

The visions we hold of the future, whether they are of utopias or dystopias, are not simply a matter of personal imagination. Our conceptions of the future are mediated to us as much as they are privately created by us. To this point, futures studies have not developed an integrative and broad-based framework for considering the social mediation of futures. Understanding how social mediation impacts on our futures visioning requires an interpretive framework that can cope with the multilayered nature of futures visions, the worldviews that are associated with them and a theory of mediation that can be applied within such a context of ‘depth’. Using theory-building methodology, the current paper attempts this task by describing a theory of social mediation that builds on the integral futures framework. An application of the framework explores the relationship between various scenarios of health care futures, their associated worldviews and the mediational factors that influence our visions of future health care systems.     

Why mutual funds “underperform”

I propose a parsimonious model that reproduces the negative risk-adjusted performance of actively managed equity mutual funds. In the model, a fund manager can generate state-dependent active returns at a disutility. Negative expected performance and mutual fund investing simultaneously arise in equilibrium because the active return the fund manager generates covaries positively with a component of the pricing kernel that the performance measure omits, consistent with recent empirical evidence. Using data on U.S. funds, I also document new empirical evidence consistent with the model's cross-sectional implications.     

The “price puzzle” reconsidered

A large literature has employed structural vector autoregressive (SVAR) models to investigate the empirical effects of U.S. monetary policy. Many of these models regularly produce a “price puzzle”—a rise in the aggregate price level in response to a contractionary innovation to monetary policy—unless commodity prices are included. Conventional wisdom maintains that commodity prices resolve the price puzzle because they contain information that helps the Federal Reserve forecast inflation. I examine a number of plausible alternative indicator variables and find little correlation between an ability to forecast inflation and an ability to resolve the price puzzle. Additionally, a sub-sample investigation reveals that evidence of a price puzzle is associated primarily with the 1959-1979 sample period, and that most indicators—including commodity prices—cannot resolve the puzzle over this period.     

Obstacles to a global banking system: “Old Europe” versus “New Europe”

“Old Europe” – the developed nations of continental Europe – averages only about 15% foreign bank ownership, whereas “New Europe” – the transition nations of Eastern Europe – averages about 70%. Similar findings hold elsewhere in the world – developed nations tend to have much lower foreign bank ownership shares than developing nations. We examine the causes of the differences within Europe with an eye toward more general conclusions. Our findings suggest that the low foreign bank shares in “Old Europe” – and perhaps developed nations more generally – may primarily result from net comparative disadvantages for foreign banks and relatively high implicit government entry barriers. The high foreign penetration in “New Europe” – and perhaps developing nations more generally – may be due to net comparative advantages for foreign banks and low government entry barriers, particularly in nations that reduced their state bank ownership.     

From “Broad Studies” to Internet-based “Expert Knowledge Aggregation”. Notes on the methodology and technology of knowledge integration

The article takes as a starting point Herman Kahn's concept of a process-based approach to future-oriented knowledge aggregation and integration and discusses the opportunities created by Internet technologies to achieve the goal envisioned by such a model. The article briefly introduces a general framework for analyzing knowledge aggregation, the use of various aggregation mechanisms as well as aggregation systems that rely either on human facilitators (meta-experts) or on computer algorithms. Available online instruments for knowledge aggregation and expert challenge are presented and the possibility of using them for setting up “virtual think tanks” for foresight studies is explored.     

On the determinants of “small” and “large” foreign exchange market interventions: The case of the Japanese interventions in the 1990s

During the past 30 years, central banks have often intervened in foreign exchange markets, and the magnitude of their foreign exchange market interventions has varied widely. We develop a quantitative reaction function model that renders it possible to examine the determinants of “small” and “large” interventions. We apply the model to analyzing the intervention policy of the Japanese monetary authorities (JMA) in the yen/U.S. dollar market during the period from 1991 through 2001. To this end, we use recently released official data on the foreign exchange market interventions of the JMA. We find that the JMA tended to conduct large interventions when the yen/U.S. dollar exchange rate drifted away from an “implicit target exchange rate.”     

Pricing mortgages: An interpretation of the models and results

Mortgages, like all debt securities, can be viewed as risk-free assets plus or minus contingent claims that can be usefully viewed as options. The most important options are: prepayment, which is a call option giving the borrower the right to buy back the mortgage at par; and default, which is a put option giving the borrower the right to sell the house in exchange for the mortgage. This article reviews and interprets the large and growing body of literature that applies recent results of option pricing models to mortgages. We also provide a critique of the models and suggest directions for future research.The Ohio State University and the National Bureau of Economic ResearchThe Urban Institute University of California at Los Angeles     

“Hot Hands” in bond funds

We investigate persistence in the relative performance of 3549 bond mutual funds from 1990 to 2003. We show that bond funds that display strong (weak) performance over a past period continue to do so in future periods. The out-of-sample difference in risk-adjusted return between the top and bottom decile of funds ranked on past alpha exceeds 3.5 percent per year. We demonstrate that a strategy based on past fund returns earns an economically and statistically significant abnormal return, suggesting that bond fund investors can exploit the observed persistence. Our results are robust to a wide range of model specifications and bootstrapped test statistics.
