Taking into account considerable changes in the corporate finance behaviour of listed Japanese companies during the 1990s, this paper empirically investigates the causes of the stagnation of the listed companies’ fixed investment during the 1990s, using panel data from the companies’ financial statements. Our findings include the following: (i) while positive cash flow sensitivity was detected for the companies listed during the 1990s, it was not necessarily a consequence of the binding of liquidity constraints; (ii) declines in Tobin's q explain decreases in fixed investment throughout the 1990s; and (iii) the holding of liquid assets acted as a buffer against liquidity shocks.
