Socially Responsible Investing Links for You!

SRI could be described as an attempt to change the world via economics. Usually SRI means that the investor avoids putting money into corporations which produce social undesirables (alcohol, tobacco, firearms, etc.), belong to problematic industries (defense, nuclear, etc.), or engage in poor behavior (environmental degradation, war profiteering, discrimination in management, etc.). This way the investor does not profit from social ills, and does not give such corporations the benefit of her/his investment dollars. Note that the definition of social ills depends on the investor; there are faith-based SR investors as well as both liberal and conservative SR investors. A more positive spin on SRI would have investors choosing to invest only into corporations which effect social good with their products and/or behavior... unfortunately, too few companies are completely good (by almost anyone's definition) to make this a realistic investment strategy. We're still in the do-as-little-harm-as-possible world.
SRI can also refer to shareholder activism, in which one hopes to promote positive corporate behavior by investing in a company and then voting one's shares with a social/political agenda. Shareholder activism is practiced both with poorly-behaving and with well-behaving companies.
