Barbara Kiviat discusses whether economics is a science or an ideology. Part of her conclusion:

And when you think about it, it is a little odd that we think economics would be able to do these things. After all, the economy is as much a product of sociology and policy as it is pure-form economics. Yet we’d not expect a sociologist or a political scientist to be able to write a computer model to accurately capture system-wide decision-making. The conclusion I’ve come to: while economists may have an important perspective on whether it’s time for stimulus or austerity, maybe we should stop looking to them as if they are people who are in the ultimate position to know.

Sociologists have been arguing for some time now that sociology has a lot to say about economics, including about how cultural values and ideology guide economic decision-making and actions.
