We study how geopolitical shocks reshape innovation through the contractual structure of cross-border technology adoption. Empirically, royalty flows are more sensitive than goods trade to geopolitical distance, especially where intellectual property enforcement is weak. We build a growth-trade model in which political risk raises breach hazards in licensing contracts. Firms reprice royalties but compliant adoption declines, and innovation incentives respond to the joint evolution of price and quantity. Quantitatively, fragmentation reallocates innovation and lowers the balanced-growth path ...

We study when unilateral export controls are optimal by quantifying how geopolitical rivalry reshapes trade in ideas. Empirically, cross-border technology flows are far more sensitive than goods trade to geopolitical distance, especially where IPR is weak, and these penalties intensify after 2017. Motivated by this evidence, we build a growth–trade model in which geopolitical distance raises breach risk in licensing; firms partially reprice risk via higher royalties but cannot fully insure quantities. In a consumption-only benchmark, a permanent rise in US–China geopolitical distance ...

We study how geopolitical fragmentation shapes cross-border technology licensing and innovation incentives. We show that bilateral royalty flows vary with geopolitical distance differently from goods trade, and that this relationship depends on intellectual property enforcement. To interpret these facts, we develop a growth-trade model in which geopolitical risk weakens licensing enforceability when intellectual property rights are poorly protected. Royalty payments reflect both technology adoption and licensing prices: weaker enforcement can reduce diffusion while inducing firms to reprice ...
