Coverage of the Hayek Lecture in The Daily Telegraph
Breaking with current economic orthodoxy, Robert Barro, Paul M Warburg Professor of Economics at Harvard University, said large spending plans should be undertaken only if they can be justified financially on their own merits.

“In the long run you have got to pay for it. The medium and long-run effect is definitely negative. You can’t just keep borrowing forever. Eventually taxes are going to be higher, and that has a negative effect,” he said.
“The lesson is you want government spending only if the programmes are really worth it in terms of the usual rate of return calculations. The usual kind of calculation, not some Keynesian thing.
