Industrial Concentration,Output, and Trade: An Empirical Exploration

This paper explores the relationship between concentration, output and trade usingtheory and empirical analysis of matched data on 82 manufacturing industries in seven countries. It finds that the higher is domestic concentration in an industry compared to international concentration, the lower is the domestic share of world output and thesmaller are net exports. This relationship persists even when industries with high levelsof concentration are excluded.     

The implications of ineffective internal control and SOX 404 reporting for financial analysts

The mandatory reporting of firms’ internal control effectiveness continues to be debated by equity market participants, U.S. regulatory agencies and oversight committees. We investigate the implications of material weaknesses in internal control and SOX 404 required reporting of such for financial analysts because analysts are important intermediaries in the U.S. capital market and it is not known whether analysts’ forecasts or coverage decisions are affected by firms’ internal control problems or reporting, respectively. Results of our empirical tests indicate that analysts provide less accurate forecasts and there is greater forecast dispersion for firms with ineffective internal control. We also find that firms that disclose internal control problems have less analyst coverage and that analyst following declines after the material weakness in internal control is disclosed. The results are robust to controlling for potential self-selection bias and management earnings guidance. Our study documents the consequences of ineffective internal control for an important class of financial statement users and suggests the required reporting on the effectiveness of internal control is beneficial to understanding the properties of analysts’ forecasts.     

Growth and poverty in developing countries

Despite the developing countries' impressive aggregate growth of the past 25 years, its benefits have only reached the poor to a very limited degree. Not only have the poorest countries grown relatively slowly, but growth processes are such that within most developing countries, the incomes of the poor increase much less than the average. Although many policies have been proposed to counter these trends, little has been done to estimate the possibilities for significantly reducing world poverty within a reasonable period. This paper develops a quantitative framework to project levels of poverty under different assumptions about GNP growth population growth and changes in income distribution. Although the interactions among development processes and policy instruments are not modelled in any detail, the results serve to clarify the nature of the problem. The policy simulations demonstrate that the elimination of absolute poverty by the end of this century is a highly unlikely prospect; even to achieve a substantial reduction will require a combination of policies designed to accelerate the growth of poor countries, to distribute the benefits of growth more equitably, and to reduce population increase.     

Refined racial discrimination: A case study of public employment in a southeastern city

Summary and Conclusion Though the preceding findings are not conclusive, 9 they are strongly supportive of the refined discrimination hypothesis and closely parallel Long’s conclusions in his study of job discrimination in the federal government.     

Illiquidity and the Measurement of Stock Price Synchronicity

This paper demonstrates that measures of stock price synchronicity based on market model R² s are predictably biased downward as a result of stock illiquidity, and that previously employed remedies to correct market model betas for measurement bias do not fix R² . Using a large international sample of firm-years, we find strong negative and nonlinear relations between illiquidity and R² across countries, across firms, and over time. Because variables of interest frequently relate to illiquidity as well, we illustrate the consequences of not controlling for illiquidity in synchronicity research. More generally, we demonstrate the importance of using nonlinear control variable methods. Overall, we conclude that the illiquidity-driven measurement bias in R² provides an explanation for why prior research finds low-R² firms to have weak information environments, and suggest future research carefully evaluate the sensitivity of its results to nonlinear controls for illiquidity.     

Ethical Issues Related to the Provision of Audit and Non-Audit Services: Evidence from Academic Research

Audit standards require auditors to conduct audits being independent in mental attitude from their clients. Regulators and financial statement users are concerned that auditors compromise their independence by allowing clients that contract for consulting services, i.e., non-audit services, more financial statement discretion relative to clients that demand relatively little non-audit services from their auditor. This paper begins by discussing the role of auditing in the capital markets and the various stakeholders that rely on audited financial information in making their capital allocation decisions. The paper continues by explaining the ethical dilemma inherent in audit contracts in general, and more specifically, how the provision of non-audit services threatens auditor independence. The paper concludes by summarizing research studies that report conflicting evidence that there is a violation of auditor independence due to the provision of non-audit services to audit clients.
