The evidence indicates that an increase in firms' investment costs may have played a substantial role during the US Great Recession, consistent with business cycle models in which firms face financial frictions. The negligible role played by the total factor productivity decline in accounting for the output downturn during the US Great Recession found by previous works can be explained by the movement in opposite directions of both labour and capital efficiency. However, we find that labour efficiency falling was the main force driving output downturn in the 1982 recession and the euro area Great Recession PB Wiley SN 0013-0427 YR 2023 FD 2023 LK http://hdl.handle.net/10347/31111 UL http://hdl.handle.net/10347/31111 LA eng NO Río, F del, Lores, F-X.
