"A second reason why science cannot replace judgement is the behavior of financial markets." ― Martin Feldstein Topic(s): Life More From Martin Feldstein "Increased government spending can provide a temporary stimulus to demand and output but in the longer run higher levels of government spending crowd out private investment or require higher taxes that weaken growth by reducing incentives to save, invest, innovate, and work." "A rise in the level of saving can reduce aggregate activity temporarily but only a sustained high level of saving makes it possible to have the sustained high level of business investment that contributes to the long-run growth of output." "And finally, no matter how good the science gets, there are problems that inevitably depend on judgement, on art, on a feel for financial markets." More In Life "Mastering others is strength.
