This paper analyzes the impact of foreign investments on a small country's economy in the context of international competition. To that end, we model tax and public input competition within a di¤erential game framework between two unequally sized countries. The model accounts for the widely recognized characteristic that small states are more ‡exible in their political decision making than larger countries. However, we also acknowledge that small size is associated with limited institutional capacity in the provision of public services. The model shows that the long-term outcome of international competition crucially depends on the degree of capital mobility. In particular, we show that ‡exibility mitigates against -but does not eliminate -the likelihood of collapse in a small economy. Finally, we note that the bene…cial e¤ect of ‡exibility in a small state increases with its ine¢ ciency in providing public services and with the degree of international openness.
