Accounting Conservatism and the Temporal Trends in Current Earnings’ Ability to Predict Future Cash Flows versus Future Earnings: Evidence on the Trade‐off between Relevance and Reliability*

This research reports that an increasing level of accounting conservatism over the 1973–2005 period is associated with: (1) an increase in the ability of current earnings to predict future cash flows and (2) a decrease in the ability of current earnings to predict future earnings. We also find that usefulness of earnings for explaining stock prices over book values is positively related to reliability but not to relevance. Our results hold for the constant and full samples in both in‐sample and out‐of‐sample analyses and are robust to the use of alternative measures for relevance, reliability, earnings usefulness, and conservatism. Our findings about the relations among conservatism, relevance, reliability, and usefulness suggest a trade‐off between relevance and reliability and seem to indicate that the adoption of an increasing number of conservative accounting standards has a possible adverse impact on earnings usefulness through a negative effect on reliability.     

The Demise of Investment Banking Partnerships: Theory and Evidence

In 1970 the New York Stock Exchange relaxed rules that prohibited the public incorporation of member firms. Investment banking concerns went public in waves, with Goldman Sachs the last of the bulge bracket banks to float. We explain the pattern of investment bank flotations. We argue that partnerships foster the formation of human capital and we use technological advances that undermine the role of human capital to explain the partnership's going‐public decision. We support our theory using a new data set of investment bank partnership statistics.     

Chief Executive Officer Equity Incentives and Accounting Irregularities

This study examines whether Chief Executive Officer (CEO) equity‐based holdings and compensation provide incentives to manipulate accounting reports. While several prior studies have examined this important question, the empirical evidence is mixed and the existence of a link between CEO equity incentives and accounting irregularities remains an open question. Because inferences from prior studies may be confounded by assumptions inherent in research design choices, we use propensity‐score matching and assess hidden (omitted variable) bias within a broader sample. In contrast to most prior research, we do not find evidence of a positive association between CEO equity incentives and accounting irregularities after matching CEOs on the observable characteristics of their contracting environments. Instead, we find some evidence that accounting irregularities occur less frequently at firms where CEOs have relatively higher levels of equity incentives.     

A Simple Algorithm for the Portfolio Selection Problem

The author presents a rapidly convergent algorithm to solve the general portfolio problem of maximizing concave utility functions subject to linear constraints. The algorithm is based on an iterative use of the Markowitz critical line method for solving quadratic programs. A simple example, taken from the theory of state-contingent claims, is worked out in detail. For technical convergence results, the reader is referred to the appropriate mathematical programming literature.     

Implied Spot Rates as Predictors of Currency Returns: A Note

Currency call option transactions data and the Black-Scholes option pricing model, as modified by Merton for continuous dividends and as adapted to currency options by Biger and Hull and by Garman and Kohlhagen, are used to imply spot foreign exchange rates. The proportional deviation between implied and simultaneously observed spot rates is found to be a direct and statistically significant determinant of subsequent returns on foreign currency holdings after controlling for interest rate differentials. Further, an ex ante trading rule reveals that the additional information contained in implied rates often is sufficient to generate significant economic profits.     

Briefing Paper: Why has the economy recovered?1

By the end of last year GDP (though strike affected) was 9 per cent higher than in the first half of 1981, an annual growth rate of 2.5 per cent. In this Briefing Paper we seek to explain the recovery from the recession. We conclude that much of the recovery represents a natural response of the economy after the oil and price shocks of 1979-80. The recovery occurred in spite of the deflationary Budget of 1981 and the sharp rise in interest rates in the autumn of 1981. Since 1981 fiscal policy has been stable, whereas the original intention was to tighten fiscal policy progressively in subsequent years. This stability and the fall in the inflation rate that accompanied it allowed growth to resume. We believe that the upturn would have been rather weaker (though inflation would have been lower) if the progressive tightening of the original Medium- Term Financial Strategy had been adhered to.     

Do Board Characteristics Influence Impression Management through Graph Selectivity Around CEO Changes?

Research has shown evidence of impression management through the selective use of graphs in financial reports of Australian firms changing chief executive officer. This paper examines whether boards with characteristics associated with strong corporate governance constrain impression management in the financial reports of Australian firms that change CEOs. Our tests of graph selectivity find that boards with a higher proportion of independent directors appear to be more effective in curbing any potentially opportunistic impression management by new CEOs in the period of their appointment.
