Capital and Macroeconomic Instability in a Discrete-Time Model with Forward-Looking Interest Rate Rules

Using these conditions, we show that (i) indeterminacy is more likely to occur with a greater share of payment to capital in value-added production cost; (ii) indeterminacy can be more or less likely to occur with constant capital than with variable capital; (iii) indeterminacy is more likely to occur when prices are modelled as jump variables than as predetermined variables; (iv) indeterminacy is less likely to occur with a greater degree of steady-state monopolistic distortions; and (v) indeterminacy is less likely to occur with a greater degree of price stickiness or with a higher steady-state inflation rate. In contrast to some existing research, our analysis indicates that capital tends to lead to macroeconomic instability by affecting firms' pricing behavior in product markets rather than households arbitrage activity in asset markets even under forward-looking policy rules
