摘要
This paper examines whether governments strategically use capital controls to influence the intertemporal terms of trade, i.e., the rates of return on cross-border lending and borrowing. We develop a two-country dynamic model to compare optimal capital control policy under commitment versus discretion. Under discretion, the planner over-manipulates intertemporal prices by aggressively linking capital controls to net foreign assets, generating welfare losses relative to laissez-faire. In contrast, a Ramsey planner with commitment balances current and future price management; the resulting controls are less responsive to asset positions and deliver welfare gains, even though they are time-inconsistent. Using political constraints as a proxy for commitment power, we find that capital controls co-move strongly with net foreign assets only in countries with high policy discretion. Our results suggest that a lack of commitment drives strategic financial competition and produces inefficient global capital allocations.
