The motivation for this paper is the discrepancy between actual CA responses to oil price shocks and the prediction derived from simple intertemporal optimizing models. These models indicate a decline in investment and a CA improvement as the optimal response. In this paper we introduce putty-clay technology into a two-period optimizing model and show that that leads to an increase in gross investments and a CA deterioration as an optimal response to large oil price shocks by net importers of oil. Successful adapters to the 1973/1974 oil price shocks (Korea, Taiwan) indeed followed such a policy.
