This paper presents a simple oil-exporting-country dynamic growth model with investment, consumption, passive military spending, and active military spending. Passive military spending (arms buildup) adds to security, while active military spending (conflict) depletes it, but adds to output and hence civilian capital (as a proxy for geopolitical risk premium in oil prices) in a non-monotonic way (some geopolitical risk is good for an oil exporter, but too much risk is not). It is shown that when the risk premium is sufficiently small, the optimal policy function does not support any positive active military spending at any levels of civilian capital and security. However, with sufficiently high geopolitical risk premium, the model country engages in controlled conflict (positive active military spending) when civilian capital is low. A controlled conflict in the latter case can shift the production function up, allowing the country to boost its consumption and arms buildup. This explains the big increase in the geopolitical risk premium following the Arab Spring, which included, among other disruptions, a military intervention by Saudi Arabia in Bahrain, as well as the smaller geopolitical risk premium following the recent Saudi-led war against the Houthis in Yemen. If oil prices remain low, depleting the civilian capital of Saudi Arabia and other oil-exporters, it may be rational, according to our model, to expect greater military activity, both to deal with geopolitical risks in the region, and to boost oil prices through the geopolitical risk premium.
