Should 'Scarcity' Be Part of the Definition of Economics?

Michael Mandel

Every economics textbook seems to have a definition of economics right in the first chapter. And all the definitions seem to have something to do with scarcity. Here are some real examples:

Economics is the study of choices consumers, business managers, and government offical make to attain their goals, given their scarce resources.

Economics is the study of how people make choices under conditions of scarcity and the results of those choices for society.

Economics is the study of how society manages its scarce resources

Now, I'm doing an economics textbook for McGraw-Hill, and I'm thinking about using a different definition of economics, which doesn't depend on scarcity.

Proposed definition: Economics is the study of the functioning-–and malfunctioning--of the economy, with the aim of improving living standards

My justification for a different definition is that there are big chunks of the economy where scarcity is not important, in any but a formal sense. If anything we seem to have an abundance of food and manufactured goods, and the cost of moving and manipulating information has fallen very very sharply. I'd also like to get in the sense that economics has a purpose.

Any thoughts?
