Here for your delectation are three cracking new Christian analyses of economics:
John Médaille Toward a Truly Free Market: A Distributist Perspective on the Role of Government, Taxes, Health Care, Deficits, and More . You’ll find some of John Médaille’s papers at his website, and at the Distributist Review and Front Porch Republic.
At long last it seems that John D Mueller’s Redeeming Economics: Rediscovering the Missing Element is about to appear. Mueller gives a very significant re-telling of economics’ history with Augustine and Aquinas set in their foundational place, from which I have borrowed. You’ll find some of Mueller’s stuff at the EPPC
And there are some classic Wendell Berry essays in his new What Matters?: Economics for a Renewed Commonwealth.
If you are looking for long-term causes of our ongoing financial crisis, these three are a fine place to start
