CSR Information Disclosure on the Web: A Context-Based Approach Analysing the Influence of Country of Origin and Industry Sector

Corporate social responsibility (CSR) has become a much-discussed subject in the business world. The Internet has become one of the main tools for CSR information disclosure, allowing companies to publicise more information less expensively and faster than ever before. As a result, corporations are increasingly concerned with communicating ethically and responsibly to the diversity of stakeholders through the web. This paper addresses the main question as whether CSR information disclosure on corporate websites is influenced by country of origin and/or industry sector. Analysing the websites of 127 corporations from emerging countries, such as Brazil, Chile, China, India, Indonesia, Mexico, Thailand and South Africa, it becomes evident that both country of origin and industry sector have a significant influence over CSR information disclosure on the web (CSRIDOW). Based on the data studied, country of origin has a stronger influence over CSRIDOW than industry sector.

Cost-benefit analysis of alien vegetation clearing for water yield and tourism in a mountain catchment in the Western Cape of South Africa

Economic analysis is used to assess the costs and benefits of restoration following clearing of invasive alien trees in the floristically rich Fynbos mountainous area near Franschhoek, Western Cape of South Africa. The Groot Drakenstein, Franschhoek and Jonkershoek mountains receives more rainfall than the surrounding areas and is an important source of water for the city of Cape Town. The costs of alien invasive plant removal, gully-erosion repair and reseeding with indigenous plants are considered in a case-study cost-benefit analysis of restoration, in terms of the water and tourism benefits derived. Three different options of restoration (comprehensive, moderate, basic) were analysed under three different economic scenarios (optimistic, realistic, pessimistic) and the costs of which have been weighted up against the income derived from the supply of water and tourism. The results have shown that despite the high costs of restoration, the basic restoration option costs were out-weighed by the water and tourism benefits derived. This was also true of the moderate restoration option, when evaluated under the optimistic scenario and using an 8% discount rate, or a 3% discount rate under any scenario. However, this was not the case in the moderate restoration option when using an 8% discount rate in conjunction with the realistic and pessimistic scenarios. Neither was it the case when using a 12% discount rate, irrespective of the scenario. Under no scenario was the cost of a comprehensive restoration option outweighed by the benefits quantified, irrespective of the discount rate used. It was concluded that further restoration, in addition to the mere clearing of alien invasive plants, would be economically viable under certain assumptions and conditions.     

A Note on Asymmetry in Commodity Futures Markets

This study tests for asymmetry in futures price changes using commodities from a variety of groups such as agricultural, metals, and financials. Tests are used to determine whether or not prices move up in the same fashion as they move down, over varying data frequencies. The results indicate that every commodity analyzed shows at least some degree of asymmetry.
Nous avons scruté les signes éventuels d'asymétrie dans l'évolution des prix à terme de certaines catégories de produits agricoles, industriels (pétrole et métaux) et boursiers. Des tests ont été utilisés pour déterminer si les prix moment de la même façon qu'ils descendent pour diverses fréquences d'établissement des prix (quotidien, hebdomadaire, mensuel). Il ressort de ces analyses que chaque type de produit comportait au mains un certain degré d'asymétrie.
