What Is in a Municipal Bond Rating?

Studies on the determinants of municipal bond ratings contain two conspicuous patterns: the use of financial accounting variables and the application of discriminant analysis to them. Over 70 different financial accounting variables have been specified, leading to different findings across the studies. In addition, discriminant analysis has been applied in these studies without correcting for violations of its underlying assumptions. Akaike's information criterion and Lachenbruch's U method are used to show how a probit model specified with economic base diversification, economic expansion, and fiscal management variables may be an improvement over the application of discriminant analysis to financial accounting variables in the determination of a triple A bond rating.

Can Voluntary Workplace Partnership Deliver Sustainable Mutual Gains?

This article draws on two Irish case studies to examine the nature and outcomes of voluntary workplace partnership (WP), and the conditions affecting its durability. We found that WP delivered mutual gains for all stakeholders at Aughinish Alumina (AAL), which were quite equally divided. While WP delivered most gains for management at Waterford Crystal (WC), and some for the union, worker gains were less. The WC partnership broke down after 10 years, but the AAL partnership continues. Voluntarist mutual gains partnership is feasible, but success and durability depends on specific clusters of contextual conditions, notably management support, a quality‐focused competitive strategy, insulation from market pressures, union postures, vertically aligned bundles of mutual gains practices, institutional supports, emphasis on fairness, all party commitment to performance enhancement and capital‐intensive technology. Conditions supporting WP were stronger at AAL than WC. More generally, as supports for WP in Ireland are weaker than retardants, we conclude that few mutual gains partnerships will take root, and even fewer will endure.     

THE BALANCED CAPITAL STRUCTURE

At leading companies, financial executives are becoming business partners rather than just scorekeepers. In this environment, capital structure can be a source of competitive advantage, and financial strategy issues are critical: Should your company buy back shares or issue stock, grow internally or join the M & A boom, issue fixed-rate debt or stay floating? These decisions must be addressed one company at a time, balancing the competing priorities of cost, risk, and flexibility. The most important issue, target leverage, depends on the company's desired risk profile, growth plans, and debt cost considerations. But market conditions are also very important: Can the company access the equity market? How will a repurchase announcement be interpreted? Market conditions also affect the raising of debt capital. Rather than maintaining a constant mix of fixed- to floating-rate debt, companies should shift the mix during high- or low-yield environments. Many other financing issues will effectively be decided by market convention. For example, meeting a company's needs with respect to seniority, maturity structure, call flexibility, and financial covenants is often accomplished simply by choosing the market that most closely matches the firm's cost and risk preferences.     

The impact of state legislation on the organisation of trade unions: The case of the Botswana Federation of Trade Unions (BFTU) in Botswana

Labour legislation is the unique device governments use to lay down standards and conventions in the workplace and to control industrial relations. Using focused interviews with unionists, government officials, employers and other relevant parties, this field study investigated the way in which labour legislation in Botswana affects the organisation of the country's federation of unions. The findings indicate that the BFTU's organisation is affected by the Trade Union and Employers Organisation Act. In particular, the restric‐ tions in this Act separate policy and administration in the BFTU and this has had negative implications for the union's effectiveness. The fact that its policymaking body is part‐time negatively affects coordination, communication and cooperation processes in the BFTU. According to the Act, public sector workers are not technically employees and therefore cannot belong to unions. This gives the impression that the state is not particularly convinced about the benefits of unionisation. This may create a difficult environment in which the BFTU and other unions must operate.     

Impacts of WTO restrictions on subsidized EU sugar exports

The study evaluates the impact of World Trade Organization (WTO) restrictions on the European Union (EU) sugar sector and the world sugar market. A small reduction in production quotas would be sufficient to satisfy the export subsidy limitations of the Uruguay Round agreement. Complete elimination of export subsidies by 2005 would require either a 10% reduction in production quotas or the combination of an 8% reduction in quotas and an 11% reduction in intervention prices. Higher world prices resulting from reduced EU exports would result in increased production of unsubsidized C‐sugar, with different impacts across EU member countries explained by differences in institutional pricing arrangements and marginal production costs.

Problems with detecting assumed mediation using the hierarchical multiple regression strategy

In human resource management (HRM) and allied fields (e.g., organizational behavior, management, and industrial and organizational psychology), tests of mediation are frequently conducted using the hierarchical multiple regression (HMR) strategy of Baron and Kenny [Baron, R. M., & Kenny, D. A. (1986). The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182]. Although previous research has identified a number of serious problems with this approach, the present study adds to the literature by identifying yet additional problems with its use in inferring the existence of mediation. Using a statistical simulation, we found that certain patterns of correlation coefficients guarantee inferences about mediation, whereas other patterns preclude such inferences. On the basis of various analyses including logistic regression and inspection of three-dimensional plots, we identified patterns of correlation coefficients needed to satisfy Baron and Kenny's [Baron, R. M., & Kenny, D. A. (1986). The moderator–mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51, 1173–1182] conditions for inferring mediation. The same patterns have no necessary relation to actual causal connections among variables in mediation models. Moreover, as a consequence of the failure of the HMR strategy to detect mediating effects, many instances of actual mediation in HRM and allied fields may have gone undetected. In view of the foregoing, we conclude that the HMR strategy should no longer be used in testing for mediation.
