Do good ethics make good business?

Most of us like to think we are principled, that our actions are guided by an ethical code. But how ethical are we really? And when it comes to business do ethics fly out of the window as we go off in search of profits? In the Balance explores ethics with a multi-millionaire venture capitalist, a Harvard professor of business history, an expert on business in India, and a fund manager who advocates ethical investment. Plus as the year draws to a close, we send Colm O'Regan up to his garret to compose the definitive poem for 2012. Spurred on by that, Justin Rowlatt's guests, Ed Conard, Nancy Koehn, Deepak Lalwani and Gervais Williams give us their predictions for 2013.
