Code and Conduct: Predictors of Irsih Managers' Ethical Reasoning

We analyse Irish managers' perceptions about the degree of wrongness of ten types of unethical conduct. In-person interviews with 348 managing directors of Irish-owned businesses who report their perceptions of the degree of wrongness of ten business ethics problems (the dependent variables) yield the data for our study. Predictors of managers' ratings include the existence of a business code of ethics, perceived frequency of occurrence of the given acts, company size and sector, union membership, Irish business ownership and independence (the independent variables). Results indicate that approximately 75% of those sampled are independent Irish owned businesses but few (only 22% of this sample) have a formal business code. Regression analyses reveal that small firms with a code of ethics predict higher wrongness ratings for managers in regard to the practices of unfair pricing and delayed payments (unethical behavior involving firms) but managers also consider such acts the least wrong overall. Wrongness ratings on the eight remaining unethical acts are explained by the manufacturing sector. However, manufacturing firms in Ireland also have a high percentage of unionised workers indicating that unions influence managerial thinking about social and employee ethics (e.g., discrimination, insider trading). The traditional adversarial Industrial Relations model is useful in noting that unions are important in setting ethical standards for indigenous Irish-owned businesses. Given this reality, management in small, manufacturing firms should work with unions to create a more formal ethics code in order to guard against corruption and to remain competitive in the international marketplace. Those without strong unions might articulate their own organisational values.     

The role of rating agencies in the market for charitable contributions: An empirical test

Rating agencies play the role of information intermediaries in the market for donations. These watchdog organizations obtain and interpret accounting data and other information about charitable organizations and report ratings to help donors select among the many organizations soliciting contributions. In the age of the internet, information from Internal Revenue Service Form 990 returns prepared by tax-exempt organizations is more readily accessible than ever before. This study examines whether the zero- to four-star ratings provided by Charity Navigator have additional information content for donors. Charity Navigator was selected because its rating system relies almost exclusively on the 990 returns and presumably adds value by incorporating peer-group expectations for various ratios and by presenting straightforward and concise data. Using a random sample of 405 charities rated by Charity Navigator, our results suggest that rating changes do impact contributions. Positive rating changes were associated with an increase in contributions and organizations with a decline in rating were associated with decreased contributions. These effects were in addition to what would be predicted using an efficiency ratio commonly computed from Form 990 accounting data and other control variables.     

International research on vegetable improvement in East and Southern Africa: adoption,impact, and returns

There is a lack of evidence for impact at scale of vegetable research and development, although the importance of vegetables for human nutrition and smallholder incomes is generally understood. We therefore study adoption and impact of improved tomato and African eggplant varieties developed through international agricultural research, released by national agricultural research and extension systems, and supplied to farmers by private seed companies in East and Southern Africa from 1990 to 2014. The study finds that in 2014, varieties developed by the World Vegetable Center accounted for 50% of tomato and 98% of African eggplant commercial seed production in East and Southern Africa. For Tanzania alone, investment in crop improvement generated economic gains of US$ 255 million for tomato and US$ 5 million for African eggplant up to 2014. The internal rate of return is 26% for tomato and 12% for African eggplant, though we project the latter to increase to 26% by 2024 as the variety was released only in 2007. These findings support the view that agricultural policy and investment reoriented towards contemporary nutritional challenges will give high returns to investment.     

Can market power sustain endogenous growth in overlapping-generations economies?

Summary. Sustained endogenous growth is known to be impossible in OLG one-sector models without non-convexities and externalities, unless income is redistributed to the young generation. No redistribution proper is however necessary, as shown in two simple examples, if positive profits accruing to young monopolistic entrepreneurs can be sustained in equilibrium, and/or if young unionised workers can guarantee a non-vanishing share of aggregate income. In this context, market power appears, in two different forms, as a significant source of sustained endogenous growth. Received: October 3, 2000; revised version: March 9, 2001     

A simplified method of constrained parameter estimation in conjoint analysis

Part-worths estimated via regression are replaced by constrained part-worths that are as close to the original part-worths as possible subject to any a priori constraints on the ordering of preferences for the levels of each attribute.This approach produces significant improvements in validations on holdout samples when employed with either ACA or full-profile conjoint analysis. The improvements in full-profile validations are similar to those obtained when constraints are imposed with LINMAP. A smaller gain is achieved with ACA.     

Internal labour market processes

This article focuses upon internal labour market processes and reviews current theoretical and empirical material. In reporting two recent studies which indicate the variety of internal processes the authors offer some explanations for such developments, in particular their relevance to issues of managerial control.     

Indeterminacy in dynamic models: When Diamond meets Ramsey

We consider an aggregate two-periods overlapping generations model with endogenous labor, consumption in both periods of life, homothetic preferences and productive external effects coming from the average capital and labor. We show that under realistic calibrations of the parameters, in particular a large enough share of first period consumption over the wage income, local indeterminacy of equilibria cannot occur with capital externalities alone. It can nevertheless occur when there are only, even very small, vanishing labor externalities provided that the elasticity of capital-labor substitution and the wage elasticity of the labor supply are large enough. We also show that if labor externalities are slightly stronger, but still small enough to be plausible, and the elasticity of labor supply is larger, local indeterminacy occurs in a Cobb-Douglas economy. Finally, we show that a locally indeterminate steady state is generically characterized by an under-accumulation of capital. It follows therefore that while agents live over a finite number of periods, the conditions for the existence of locally indeterminate equilibria are very similar to those obtained within infinite horizon models and that from this point of view, Diamond meets Ramsey.     

Demand for international telephone traffic in Spain: An econometric study using provincial panel data

In this study we model the demand for outgoing international telephone traffic in Spain. We make use of a standard theoretical framework that incorporates the special characteristics of this type of telephone service. Consequently, equations for real expenditure per line and for the number of international calls per line are estimated.We use annual data for the 50 Spanish provinces for the period 1985–1989, and employ appropriate panel data techniques. The selected equations (one for expenditure per line in international traffic and another for the number of international calls per line) pass a battery of diagnostics. We conclude that this type of traffic, whether measured by expenditure per line or by the number of international calls per line, presents both high income and price elasticities. Moreover we find that price and income affect both the number of calls and their average duration.Likewise, we find a significant increase in social welfare when a tariff rebalancing that maintains the profit of the operating company is carried out.     

Behavioral Structure in Sociomotor Sports: Roller-Hockey

This study, part of a wider research project, presents (1) a category system for observation in roller-hockey, and (2) the results obtained with it. The behavior flow obtained with this category system was analyzed sequentially using the lag technique. The behavior patterns were compared with the results of Exact Permutations analysis of the same data. Finally, the main behavior patterns, and their psychosocial implications, are described. The most distinctive feature of the study is its use of specific software in both the coding and the analysis of the observational categories.
