Does Audit Committee Accounting Expertise Help to Promote Audit Quality? Evidence from Auditor Reporting of Internal Control Weaknesses

In this study, we examine whether audit committee accounting expertise helps to promote audit quality by motivating auditors to conduct diligent internal control audits and make appropriate internal control assessments because audit committee accounting expertise safeguards auditors from dismissal following adverse internal control opinions. Among clients with existing and likely internal control material weaknesses (as proxied by future restatements of audited financial statements), we find a greater likelihood of adverse internal control audit opinions when the audit committee has greater accounting expertise (measured by the proportion of accounting experts on the audit committee). Among all clients, we find a lower likelihood of subsequent auditor dismissal following an adverse internal control audit opinion when the audit committee has greater accounting expertise. In further analyses, we find that this lower likelihood of subsequent auditor dismissal occurs when at least two audit committee members possess accounting expertise. We also find some evidence that CFO influence (but not CEO influence) over the audit committee negates the increased likelihood of adverse internal control opinions when internal control material weaknesses likely exist, as well as the decreased likelihood of auditor dismissal following adverse internal control opinions. These findings have important implications for regulators and corporate nominating committees interested in promoting audit committee effectiveness.     

INCOMPLETE MARKETS AND COMMODITY-LINKED FINANCE IN DEVELOPING COUNTRIES

This article provides a framework for appraising new financialinstruments and evaluating the extent to which they can helpalleviate problems of incomplete credit markets and contingentclaims markets in developing countries. Although the issuesinvolved apply to any new financial instrument, we give particularattention to commodity-linked securities because many developingcountries specialize in producing a handful of primary commoditiesand are therefore exposed to substantial commodity price risks.The article looks at the supply of, demand for, and pricingof commodity-linked securities and discusses some issues thataffect their use by developing countries: their special legalstatus as sovereign debt; their feasibility (since to becometruly effective they will require liquid secondary markets);and the construction of an optimal portfolio of external debtobligations. It also discusses the potential for new financialinstruments—particularly commodity-linked securities—asa tool for risk management in developing countries.      

Bivariate garch estimation of the optimal commodity futures Hedge

Six different commodities are examined using daily data over two futures contract periods. Cash and futures prices for all six commodities are found to be well described as martingales with near-integrated GARCH innovations. Bivariate GARCH models of cash and futures prices are estimated for the same six commodities. The optimal hedge ratio (OHR) is then calculated as a ratio of the conditional covariance between cash and futures to the conditional variance of futures. The estimated OHRs reveal that the standard assumption of a time-invariant OHR is inappropriate. For each commodity the estimated OHR path appears non-stationary, which has important implications for hedging strategies.     

Racial Earnings Disparities and Family Structure

One explanation for the widening of racial earnings gaps among family heads during the 1980s is that black families were increasingly headed by females during that period. This explanation is tested using data on black and white family heads in 1976 and 1985 from the Institute for Research on Poverty's Current Population Survey. Log-earnings equations, corrected for selection bias and for the endogeneity of labor force participation, are estimated for blacks and whites in 1976 and 1985. If the impact of rising female-family headship on labor force participation is ignored, one finds support for the family structure explanation. But support for alternative explanations is also found. There are substantial impacts of within-race gender discrimination and of market racial discrimination. When the endogeneity of family structure is taken into account, further support is found for the view that endowment differences only explain a modest portion of the rising gap in earnings between black and white family heads.     

ESTIMATING SOURCES OF FLUCTUATIONS IN THE AUSTRALIAN WOOL MARKET: AN APPLICATION OF VAR METHODS

Vector autoregression (VAR) methods are used to analyse the contribution of supply, demand and policy shocks to unpredictable fluctuations in the market for Australian wool. VAR procedures are compared with conventional structural econometric models as methods for decomposing sources of instability. While each has advantages and disadvantages, VAR procedures might be viewed as preferable when the underlying market structure is complex and uncertain, as it is in the case of wool. Based on the results obtained, demand shocks are the dominant source of uncertainty in the wool market in the absence of Australian Wool Corporation intervention, but intervention has blunted their effects, reducing market uncertainty and increasing the average level of prices and revenues.     

Towards an Understanding of Ethical Behaviour in Small Firms

Allthough small business accounts for over 90% of businesses in U.K. and indeed elsewhere, they remain the largely uncharted area of ethics. There has not been any research based on the perspective of small business owners, to define what echical delemmas they face and how, if at all, they resolve them. This paper explores ethics from the perspective of small business owner, using focus groups and reports on four clearly identifiable themes of ethical delemmas; entrepreneurial activity itself, conflicts of personal values with business needs, social responsibility and the impact of owners' personality on business ethics. The mechanisms for resolving ethical dilemmas is not at all clear, as there appears to be a web of filters which are used in an inter-connected way. However a common starting point for resolving an ethical delemma which involves others is based on identifying who it is (e.g., a friend or institution) and the quality of the relationship with that person. The research yielded a rich source of material on business ethics and it is clear that future researchers must focus on this sector if business ethics is to make significant advances.     

The spillover effects of biofuel policy on participation in the conservation reserve program

This paper studies the spillover effects of rising biofuel production on participation in the Conservation Reserve Program. Landowner participation decisions are modeled using a real options framework. We develop a land use decision model that captures biofuel-driven structural changes in market demand and derive threshold conditions that trigger participation in the program. We then quantify the impacts of biofuel production on participation at both the national and state levels using Monte Carlo simulations. The model is also used to analyze how changes in the persistence of the biofuel production boom and in the volatility of farming returns affect conservation participation decisions. Policy implications of the results are discussed.
