In the bust, the ABCT says that new unsustainable capital projects initiated in the boom are liquidated: capital projects that were unsustainable are folded up and liquidated, and this drives the bust (Garrison 1997: 25).
The empirical evidence, however, does not support this. A great deal of the fluctuations in output and employment during recessions are caused by changes in capacity utilisation at mature firms and businesses (Kuehn 2013: 506, citing Davis, Haltiwanger, and Schuh 1996: 56–81), often connected with the need to liquidate inventory. This is what often characterises and drives the fall in investment, not liquidation of new projects.
And once we understand too that
(1) the loanable funds model as used and required in the ABCT is wrong, given that the unique Wicksellian natural rate of interest cannot be defined outside a one commodity world, andwe can see how flawed and wrong the ABCT is.
(2) interest rates do not provide the necessary inter-temporal coordination of real saving and investment
