The element of the neoclassical model that has come under critical scrutiny in the Vermont press lately is the notion that GDP — a measure of the dollar value of all goods and services produced by the economy — is a practical and useful measure of economic well-being. It’s not hard to see why GDP is being re-thought: last month tropical storm Irene dumped tropical-rainforest quantities of water on the state in just a few hours, leading to major damage from unprecedented flooding. Rivers filled their flood plains and kept rising, sweeping away roads, bridges, and houses, ruining homes, lives, farms, and communities. The publicly owned infrastructure is being put back with great speed and efficiency. Is all this public works effort a net benefit to the economy, or not?
GDP says yes, absolutely. Common sense — and steady-state economic theory — says no.
