Mandatory IFRS adoption and management forecasts: The impact of enforcement changes

We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure.     

Labour market characteristics and surviving import shocks

This paper investigates whether different labour market characteristics amplify or dampen the local labour market impacts from Chinese import competition exposure. I exploit state‐level variation in initial, pre‐shock labour market characteristics and regional variation across local labour markets in exposure to Chinese imports for identification. I find that local labour markets in states with higher union density experience more severe adverse consequences as a result of increased import exposure. Conversely, higher initial minimum wages help mute the negative impacts of the China shock. I also provide some evidence that exceptions to employment‐at‐will legislation can affect employment responses to increased Chinese imports. Finally, examining all policies together in an index, I show that higher levels of policies intended to benefit and protect workers can actually magnify the extent of the damage inflicted by import competition. My results suggest that initial labour market characteristics and policies can play an important role in understanding why local labour markets react differently to trade shocks.     

Recent Developments in the Theory of the Firm

Abstract
This article reviews recent literature on the theory of the firm. The issues addressed include the role and determinants of the size of firms, the financial structure and organisation of labour in firms, and the policy implications of this research .     

Using R to teach econometrics

R, an open‐source programming environment for data analysis and graphics, has in only a decade grown to become a de‐facto standard for statistical analysis against which many popular commercial programs may be measured. The use of R for the teaching of econometric methods is appealing. It provides cutting‐edge statistical methods which are, by R's open‐source nature, available immediately. The software is stable, available at no cost, and exists for a number of platforms, including various flavours of Unix and Linux, Windows (9x/NT/2000), and the MacOS. Manuals are also available for download at no cost, and there is extensive on‐line information for the novice user. This review focuses on using R for teaching econometrics. Since R is an extremely powerful environment, this review should also be of interest to researchers. Copyright © 2002 John Wiley & Sons, Ltd.     

EFFECT OF FED POLICY ACTIONS ON THE DEFAULT LIKELIHOOD OF COMMERCIAL BANKS

Using a measure of default likelihood based on an option pricing method, we provide evidence that Fed policy actions affect the financial distress of commercial banks. When the Fed increases (decreases) interest rates, the measure of default likelihood increases (decreases). We show that when the Fed uses a tight money policy, the increase in default likelihood is more pronounced for banks that have less capital, have greater financial leverage, are smaller, have fewer growth opportunities, and have lower asset quality. Additionally, the effects on bank default likelihood are more pronounced when the Fed's policy signals less concern about economic growth, as indicated by its bias toward further tightening, and when there is a market expectation of higher short‐term market rates in the future.     

INTRA-INDUSTRY EFFECTS OF BOND RATING ADJUSTMENTS

Several studies find that bond rating downgrades cause negative valuation effects. Other studies find that signals conveyed by earnings releases, earnings forecasts, bankruptcies, and stock offerings of individual firms can be transmitted to their corresponding industries. By combining the two sets of studies, we hypothesize that bond rating changes may contain relevant information not only about the firm, but also about the corresponding industry. We find significantly negative valuation effects for rating downgrades, which are transmitted throughout the industry. Furthermore, we find that intra-industry effects depend on particular characteristics of the bond downgrade, the downgraded firm, and industry rivals. Specifically, the negative intra-industry effects are more pronounced when (1) the downgraded firm experiences a more severe share price response to the bond rating downgrade, (2) the downgraded firm is dominant in the industry, (3) the downgraded firm is more closely related to its rivals in the industry, and (4) the downgrade is due to a deterioration in the firm's financial prospects.     

Working While the World Sleeps: A Consideration of Sleep and Shift Work Design

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees.     

Directors' Duties and Corporate Governance: Have We Gone Too Far?

We review recent policy initiatives in Australia, such as corporate governance reporting requirements and innovations in defining directors' roles and responsibilities, and argue that such initiatives are often premised on overly simplistic models of the role played by directors. The role and effectiveness of directors vary according to the economic activity of the firm; hence, uniform guidelines for board composition, for example, are unlikely to be economically desirable. Likewise, statutory definitions of directors' duties are unlikely to be effective unless they allow for directors' roles to vary according to circumstance. Conversely, broad legal definitions will be problematic because of uncertainties in judicial interpretation.     

The Economic Value of Volatility Timing

Numerous studies report that standard volatility models have low explanatory power, leading some researchers to question whether these models have economic value. We examine this question by using conditional mean-variance analysis to assess the value of volatility timing to short-horizon investors. We find that the volatility timing strategies outperform the unconditionally efficient static portfolios that have the same target expected return and volatility. This finding is robust to estimation risk and transaction costs.     

Sources of Bank Interest Rate Risk

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.
