For Keynesians and Austrians, "uncertainty" means two different things

"Keynesian economics has witnessed a remarkable resurgence since the crisis of 2008. The inability of mainstream economics to predict or explain the crisis led many economists to become skeptical of its core macroeconomic tenets. Several have turned the clock back to the ideas of Keynes to make sense of the housing bubble and the ensuing recession. One such explanation inspired by the General Theory emphasizes the endemic uncertainty of the future and its implications for market stability. … this line of thought bears a striking resemblance to Austrian ideas. Moreover, its rejection of mathematical probability as a foundation for expectations is echoed by several prominent Austrian economists. Nevertheless, while Keynesians conclude that the uncertainty of the future renders a market economy inherently unstable, Austrians embrace uncertainty without losing faith in the order generated by a market economy. What lies at the root of this puzzle?" (03/23/13)
