This paper presents the concept of ethical economy (Wirtschaftsethik) and the relation between ethics and economics on the basis of the work of the German ethical economist Peter Koslowski. The concept of ethical economy includes three levels: micro, meso and macro levels; and it also deals with the philosophical analysis of the ethical foundations of the economy. After the discussion of these elements of the ethical economy, the paper presents some possible research topics for a research agenda about economic ethics or ethical economy.
