On the structure of analyst research portfolios and forecast accuracy
Journal of Accounting Research
April 9, 2009
This study provides insights into the forces and constraints that shape analyst research coverage along country and sector dimensions and the impact of the structure of an analyst's portfolio on forecast accuracy. We find that analyst specialization by country and sector is sensitive to the extent to which firms within a country or sector and firms across country-sectors are exposed to common economic forces, the potential for revenue generation, and broker culture. Our tests indicate that existing research on the relation between analyst portfolio structure and forecast accuracy may suffer from an endogeneity bias. We use our analysis of analyst specialization to develop controls for this bias. Once we employ these controls, we find that country diversification is associated with superior forecast accuracy. However, the relation between sector diversification and forecast accuracy is context-specific. Specifically, sector diversification enhances forecast accuracy in an international context, while it detracts from forecast accuracy in a domestic U.S. context.
Evidence on Corporate Hedging Policy
Cambridge University Press
September 1, 1996
This paper provides empirical evidence on the determinants of corporate hedging decisions. The paper examines the evidence in light of currently mandated financial reporting requirements and, in particular, the constraints placed on anticipatory hedging. Data on hedging are obtained from 1992 annual reports for a sample of 3,022 firms. Out of the 771 firms classified as hedgers, 543 firms disclose information in their annual reports on their hedging activities; the remaining 228 firms report use of derivatives but no information on hedging activities. Based on the evidence, I draw the following conclusions with respect to the models of hedging: evidence is inconsistent with financial distress cost models; evidence is mixed with respect to contracting cost, capital market imperfections, and tax-based models; and evidence uniformly supports the hypothesis that hedging activities exhibit economies of scale.
Accounts Receivable Management Policy: Theory and Evidence
American Finance Association
March 1, 1992
This paper develops and tests hypotheses that explain the choice of accounts receivable management policies. The tests focus on both cross-sectional explanations of policy-choice determinants, as well as incentives to establish captives. We find size, concentration, and credit standing of the firm's traded debt and commercial paper are each important in explaining the use of factoring, accounts receivable secured debt, captive finance subsidiaries, and general corporate credit. We also offer evidence that captive formation allows more flexible financial contracting. However, we find no evidence that captive formation expropriates bondholder wealth.
