Bringing to your attention two recent publications by Journal of Markets & Morality contributors:
The first is Less Than Two Dollars a Day: A Christian View of World Poverty aand the Free Market, by Kent Van Til, published by Eerdmans.
The second is Economics in Christian Perspective: Theory, Policy, and Life Choices, by Victor Claar and Robin Klay, published by InterVarsity.
Based on a quick perusal, I guess that the latter entry is a little more sanguine about the achievements and potential of free markets with respect to Christian social obligations. Regardless, both books take seriously both economics and theology, a rare but necessary prerequisite for helpful analysis in this area.
All three authors, by the way, teach at Hope College.
