We characterize investments in supply chain resilience in a geopolitical duopoly. The domestic firm balances the option to benefit from potential competitive advantages against riskiness and geopolitical instability associated with foreign sourcing. We show that the domestic firm has insufficient incentives to invest in supply chain resilience, thereby justifying a subsidy policy. We characterize conditions for underinvestment. We also characterize a number of factors which are central for optimal subsidy policy.
