Consumption and Portfolio Choice over the Life Cycle

This article solves a realistically calibrated life cycle modelof consumption and portfolio choice with non-tradable laborincome and borrowing constraints. Since labor income substitutesfor riskless asset holdings, the optimal share invested in equitiesis roughly decreasing over life. We compute a measure of theimportance of human capital for investment behavior. We findthat ignoring labor income generates large utility costs, whilethe cost of ignoring only its risk is an order of magnitudesmaller, except when we allow for a disastrous labor incomeshock. Moreover, we study the implications of introducing endogenousborrowing constraints in this incomplete-markets setting.     

Do External Auditors Perform a Corporate Governance Role in Emerging Markets? Evidence from East Asia

In emerging markets, the agency conflicts between controlling owners and the minority shareholders are difficult to mitigate through conventional corporate control mechanisms such as boards of directors and takeovers. We examine whether external independent auditors are employed as monitors or as bonding mechanisms, or both, to alleviate the agency problems. Using a broad sample from eight East Asian economies, we document that firms with agency problems embedded in the ownership structures are more likely to employ Big 5 auditors. This relation is evident among firms that raise equity capital frequently. Consistently, firms hiring Big 5 auditors receive smaller share price discounts associated with the agency conflicts. Also, we find that Big 5 auditors take into consideration their clients' agency problems when making audit fee and audit report decisions. Taken together, these results suggest that Big 5 auditors do have a corporate governance role in emerging markets.     

Does the Market Value Financial Expertise on Audit Committees of Boards of Directors?

We examine three‐day cumulative abnormal returns around the announcement of 702 newly appointed outside directors assigned to audit committees during a period before implementation of the Sarbanes‐Oxley Act (SOX). Motivated by the SOX requirement that public companies disclose whether they have a financial expert on their audit committee, we test whether the market reacts favorably to the appointment of directors with financial expertise to the audit committee. In addition, because it is controversial whether SOX should define financial experts narrowly to include primarily accounting financial experts (as initially proposed) or more broadly to include nonaccounting financial experts (as ultimately passed), we separately examine appointments of each type of expert. We find a positive market reaction to the appointment of accounting financial experts assigned to audit committees but no reaction to nonaccounting financial experts assigned to audit committees, consistent with accounting‐based financial skills, but not broader financial skills, improving the audit committee's ability to ensure high‐quality financial reporting. In addition, we find that this positive reaction is concentrated among firms with relatively strong corporate governance, consistent with accounting financial expertise complementing strong governance, possibly because strong governance helps channel the expertise toward enhancing shareholder value. Together, these findings are consistent with financial expertise on audit committees improving corporate governance but only when both the expert and the appointing firm possess characteristics that facilitate the effective use of the expertise.     

Firms' Off-Balance Sheet and Hybrid Debt Financing: Evidence from Their Book-Tax Reporting Differences

We match large U.S. corporations' tax returns during 1989–2001 to their financial statements to construct a firm‐level proxy of firms' use of off‐balance sheet and hybrid debt financing. We find that firms with less favorable prior‐period Standard & Poor's (S&P) bond ratings or higher leverage ratios in comparison to their industry report greater amounts of interest expense on their tax returns than to investors and creditors on their financial statements. These between‐firm results are consistent with credit‐constrained firms using more structured financing arrangements. Our within‐firm tests also suggest that firms use more structured financing arrangements when they enter into contractual loan agreements that provide incentives to manage debt ratings. Specifically, we find that after controlling for S&P bond rating and industry‐adjusted leverage, our sample firms report greater amounts of interest expenses for tax than for financial statement purposes when they enter into performance pricing contracts that use senior debt rating covenants to set interest rates. Furthermore, we find that the greatest book‐tax reporting changes occur when firms become closer to violating these debt rating covenants. These latter findings are consistent with firms' contractual debt covenants influencing their use of off‐balance sheet and hybrid debt financing.

Exclusive Contracts And Market Power: Evidence From Ocean Shipping

There is a substantial theoretical literature on the potential effects of loyalty contracts, but relatively little empirical work. We employ the event study methodology to examine the competitive effects of exclusionary contracts in the ocean shipping industry, where they were the subject of an extended legal and political struggle. We find that some of the most important events in this conflict caused significant changes in shipping firms' stock returns, indicating exclusive contracts increased their profits. We then examine the effect of these events on net exporting industries' stock returns, and provide evidence that these contracts contributed to carriers' market power.     

Capitalization versus Expensing: Evidence on the Uncertainty of Future Earnings from Capital Expenditures versus R&D Outlays

We propose and implement a new method to estimate the relation between R&D investments and the uncertainty of future benefits from those investments. The empirical analysis compares the relative contributions of current investments in R&D and PP&E to future earnings variability using a sample of roughly 50,000 firm-year observations from 1972–1997. Evidence is strongly consistent with the hypothesis that R&D investments generate future benefits that are far more uncertain than benefits from investments in PP&E. Our results should help the current discussion on accounting for R&D and the methodology might be helpful in standard setting in other contexts as well.     

Erklärungsansätze für vertragswidriges Verhalten Versicherungsnehmern aus Sicht der ökonomischen Theorie

The two main purposes of this paper are an introduction to the economic analysis of insurance fraud and furthermore a derivation of factors that determine fraudulent behavior of policyholders on insurance markets. Consequently, we analyze the strategic decision problems of insurance companies and the policyholders and identify some factors that can help to reduce fraudulent behavior. In this context we evaluate two derived starting points for the combat against insurance fraud: fraud detection systems and a consequent charge policy of detected defrauders. We illustrate that both points can help to reduce the cost of fraud. Furthermore, we enhance our earlier analysis with respect to the empirical fact that some individuals care about fairness or — in the insurance fraud context — the legitimacy of their actions. Surprisingly, in some market situations these concerns of some policyholders do not lead to a lower fraud probability. Finally, we discuss how and to what extent insurance companies can influence such ethical concerns of policyholders. On that score, we distinguish insurance specific and insurance unspecific factors and their impact on the consumers attitudes towards insurance fraud.     

Corporate Governance: Factors Influencing Voluntary Disclosure by Publicly Traded Canadian Firms*

We report on the comprehensiveness of voluntary corporate governance disclosures in the annual reports and management information circulars of Toronto Stock Exchange (TSE) firms. We focus on disclosure of the corporate governance practices implemented by our sample of TSE 300 firms vis‐à‐vis the 14 guidelines set out in the TSE's report on corporate governance Where Were the Directors? Our analysis indicates that only a very few firms disclose that they have fully implemented the TSE guidelines, and that the extent of disclosure of corporate governance practices implemented varies widely among the firms. We then test factors associated with the comprehensiveness of such disclosures and the choice of disclosure medium using simultaneous equations multivariate analysis. We also assess the influence of publicized corporate governance failures on disclosure. Overall, our results suggest that the choices of disclosure medium and the extent of disclosure are made concurrently, and are influenced by the strategic considerations of management.
