There is a new economic theory! 

Divine economy theory stems from Austrian economics and classical liberalism. It is economics that uses the subjectivist methodology to build new models to further our understanding of purposeful human action. 

Divine economy theory is purely scientific without denying the most essential aspect of the human reality, and that aspect is the spiritual reality of human beings.

The theory unfolds in a series of books, each centered around a dynamic model constructed using the subjectivist methodology. And these are combined into the magnum opus.

Here is the divine economy theory series:

MORE THAN LAISSEZ-FAIRE (2008)

The HUMAN ESSENCE of Economics (2009)

ETHICAL ECONOMICS for today and tomorrow (2010)

Liberty & Justice of Economic Equilibrium (2011)

These books are also available as combined sets.
