The internet and the electronic economy are a technological revolution whose secular importance is apparent. The internet eliminates the temporal and spatial constraints on the exchange of information. It changes deeply the world of production and of labour. It transforms the exchange relationships between producers and consumers as well as between the suppliers within the supply-chain. The electronic economy is able to generate more accurate con­ sumer profiles and, therefore, a more powerful and effective marketing di­ rected to the individual consumer. There is no industry that is not undergoing thorough changes caused by the internet. The volume at hand gives an analysis of the internet revolution. It covers questions reaching form the highly controversial thesis of the end of property rights in the internet caused by the non-rivalry of the "consumption" of in­ formation to questions regarding the repercussions of the internet on our understanding of the human person. Technological changes like the introduction of the electronic economy pose the question of how to handle it and how to manage reasonably its ethi­ cal problems and dilemmas. The ethical problems and the business ethics of the electronic economy in the fields of production and labour, of consump­ tion, and in handling trust and the abuse of trust are analysed by the contribu­ tions from applied ethics and business ethics.
