Economic Instability and Aggregate Investment

roughly consistent with the theory (e.g., the use of hurdle rates that are much larger than the opportunity cost of capital as predicted by the CAPM), there has been little in the way of tests of the theory. In addi-tion, there have been few attempts to determine whether irreversibility and uncertainty matter for investment at the aggregate level.
