I extend prior corporate disclosure research by examining the association between six international environmental factors and the level of corporate voluntary disclosure practices using 100 Egyptian listed non-financial firms. The results of regression analysis indicate that the level of voluntary disclosures is positively and significantly associated with international socio-political institutions, international accounting standards, and international financial institutions. However, I find no significant association between the level of voluntary disclosures and global competition, the international stock market, and information technology and communication. Of the five control variables that I included in regression models, only the legal form associates significantly with the level of voluntary disclosure practices. The findings further our understanding of accounting practices in a developing country context. The subject organizations can use the findings of the study to improve their accounting disclosure systems. The Capital Market Authority in Egypt also can use the findings of the study to improve accounting disclosure regulations in Egypt.
