I always felt that the role of moral philosophy in economics entered when value judgments appeared – and as a result, it would be possible to separate this issue from the domain of economic science.
However, a book I just purchased (Economic Analysis, Moral Philosophy, and Public Policy – by Hausman and McPherson) appears willing to attack this belief of mine:
Our job will be … to show how knowing moral philosophy helps one do economics and policy evaluation better
Given how heavily another Hausman book (The Philosophy of Economics: An Anthology) helped shape my view of the economic method, I am sure that this book will end up with me talking like a very different economist. You have been warned 😉
