A random coefficient approach to the predictability of stock returns in panels

© The Author, 2014. Most studies of the predictability of returns are based on time series data, and whenever panel data are used, the testing is almost always conducted in an unrestricted unit-by-unit fashion, which makes for a very heavy parametrization of the model. On the other hand, the few panel tests that exist are too restrictive in the sense that they are based on homogeneity assumptions that might not be true. As a response to this, the current study proposes new predictability tests in the context of a random coefficient panel data model, in which the null of no predictability corresponds to the joint restriction that the predictive slope has zero mean and variance. The tests are applied to a large panel of stocks listed at the New York Stock Exchange. The results suggest that while the predictive slopes tend to average to zero, in case of book-to-market and cash flow-to-price the variance of the slopes is positive, which we take as evidence of predictability.

The influence of remuneration structures on financial reporting quality: evidence from Australia

This cross-sectional study investigates the influence of a company's remuneration structure on managers' opportunistic behaviour. The findings support the proposed hypothesis that a higher level of compliance with Remuneration Principle 8-ASX Corporate Governance Council) is associated with a lower level of earnings management. The findings support the efficient functioning of the ASX proposed remuneration structure. This cross-sectional study investigates the influence of remuneration structures on financial reporting quality, based on a sample of companies listed on the Australian Securities Exchange (ASX). Compliance with Remuneration Principle eight issued by ASX (providing recommendations on formation, operation and disclosure of remuneration committees) is expected to improve financial reporting quality represented by a decreased level of earnings management. This study expands the corporate governance literature by examining an under-researched mechanism to address the agency problem. Earnings management, as a consequence of the agency problem, is measured using the level of absolute discretionary accruals. In this study, we use the modified Jones model to measure the level of discretionary accruals and the existence of reduced earnings management. The study is conducted using a random sample of 214 firm-year observations selected from the ASX listed companies. Our findings show a higher level of compliance with the principle on remuneration is associated with lower levels of earnings management. The findings support the efficient functioning of the ASX-proposed remuneration structure in reducing earnings manipulations.

Was audit quality of Laventhol and Horwath poor?

Laventhol and Horwath (L&H), the then seventh largest accounting firm in the US, declared bankruptcy in November 1990. The firm claimed that its bankruptcy was due to the perception of it being a deep pocket rather than inherent deficiencies in its performance. In this study, we examine whether the audit quality of L&H was lower than other auditors. Results do not show that L&H is associated with lower quality audits either in terms of lower likelihood of issuing modified audit opinion, higher levels of discretionary accruals for its clients, or lower predictability of discretionary accruals for future non-discretionary net income for its clients than for clients of other auditors. Results of additional tests also do not suggest that auditors that take up clients of L&H report differently from L&H. This evidence does not support the proposition that L&H’s audit quality was less than audit quality of other audit firms during the period leading up to the bankruptcy.
