It is well known that if there are mild sector-specific externalities, then the steady state of the standard two-sector real business cycle model can become indeterminate and endogenous business cycles can arise. We show that this result is not robust to the introduction of standard intertemporal capital adjustment costs, which may accrue when total capital is adjusted or when each sector's capital is adjusted. We find for both forms of adjustments costs that the steady state is determinate for all empirically plausible parameter values. We also find that determinacy occurs for a much larger range of parameter values when adjusting each sector's capital is costly.
