On estimation of some abbreviated social welfare measures

Point and interval estimations of two abbreviated social welfare functions are studied based on Schutz and Gini coefficients. The limit distributions of the estimators are derived in terms of sample L-moments and mean absolute deviation. A simulation study is performed to assess the bias in the estimators and the coverage probability of the confidence intervals. Unlike the previous studies our results do not require the grouping of population into a fixed number of quantiles. The proposed methods use distribution-free unbiased estimators and exact sample L-moment variances. An application is given that illustrates the benefits of the proposed methods.     

Reexamining the Expected Effect of Available Resources and Firm Size on Firm Environmental Orientation: An Empirical Study of UK Firms

An emergent body of literature examined why some firms apply some environmental initiatives while other firms do not take responsibility for their natural environment? Thus, firm environmental orientation (responsiveness and performance) are linked in the literature to several variables. Unfortunately, the relationship between firm environmental orientation and either available resources or firm size showed mixed results and inconclusive evidence. Therefore, the aim of this paper is to show empirically how available resources and firm size can explain differences in firm environmental responsiveness and environmental performance. Econometric results of environmental responsiveness using the logistic regression model demonstrated that firm size does appear to add something unique in explaining differences in environmental responsiveness while available resource can be safely dropped from the model. However, econometric analysis of environmental performance using the maximum-likelihood random effects model showed strong evidence that available resources and firm size are significant predictors of firm environmental performance.     

Political change and informality

This paper examines informality during the political and economic turmoil that accompanied the Arab Spring revolution in Egypt. The paper focuses on unprotected employment and the extent to which it changed by educational level immediately after the January Uprising of 2011. We find that over time and particularly after the revolution, informal employment has increased for both high‐ and low‐educated workers, albeit through different paths: high‐educated workers were more likely to be stuck in informality, while low‐educated formal workers were more likely to lose their contracts. The increase in informal employment in the wake of the Arab Spring is more pronounced for the high‐educated. The results suggest a high level of rigidity in the Egyptian labour market, even in the wake of the Arab Spring.     

The impact of financial performance on environmental policy: does firm life cycle matter?

Existing literature has provided inconclusive evidence regarding the impact of financial performance on firm policy relating to environmental issues. In this paper, we propose that the influence of corporate financial performance on corporate environmental policy is unlikely to be monotonic but, rather, will vary with firm life cycle. We test this hypothesis by the application of static and dynamic techniques on panel data from UK companies. The results provide support for our hypotheses that financial performance has the strongest impact on environmental policy in the maturity stage of the firm life cycle and the weakest impact in the rapid growth stage.

Perceived international environmental factors and corporate voluntary disclosure practices: An empirical study

Drawing upon the contingency theory of organisations, we identify a set of perceived international environmental factors and examine how these factors influence a company's voluntary disclosure levels. The perceived international environmental factors identified are (a) intensity of global competition, (b) international socio-political institutions, (c) international accounting standards, and (d) international financial institutions. Based on data collected from 100 Egyptian non-financial listed companies, the results of multiple regression analysis indicate that the level of a company's voluntary disclosure is positively and significantly associated with its perceived influence of (a) international socio-political institutions (such as the United Nations, the European Union, the Association of South East Asian Nations, the World Trade Organization, and the Organization for Economic Co-operation and Development), (b) international accounting standards, and (c) international financial institutions (such as the World Bank and the International Monetary Fund). Contrary to our expectations, our findings reveal no significant association between voluntary disclosure level and perceived intensity of global competition. Our study contributes to the international accounting disclosure field by providing evidence from Egypt that perceived international environmental factors may influence the type and level of accounting disclosures by organisations. These findings are also applicable to other emerging countries.
