摘要：

This paper introduces strategic interactions into a Ricardian model where two countries optimize trade policies. In a Nash Equilibrium, we find that optimal import tariffs are zero, while export taxes rise with comparative advantage, aligning with but extending the unilateral model of Costinot et al. (2015) by allowing both countries to act strategically. Our analysis reveals that welfare gains from trade policy diminish when both countries pursue optimal policies. Surprisingly, a smaller country can benefit from Nash Equilibrium through higher export taxes in goods with technological advantages. Applying the model to agriculture, we assess welfare under autarky, free trade, Nash Equilibrium, and unilateral policy, showing that small, competitive nations can outperform free trade through strategic policy, providing insights into optimal trade policy across goods.

摘要：

We collect new data and present new evidence on the effects of labor scarcity on the adoption of labor-saving technology in industrializing England. Where the British armed forces recruited heavily, more machines that economized on labor were adopted. For purposes of identification, we focus on naval recruitment. Using warships’ ease of access to coastal locations as an instrument, we show that exogenous shocks to labor scarcity led to technology adoption. The same shocks are only weakly associated with the adoption of non-labor saving technologies. Importantly, there is also a synergy between skill abundance and labor scarcity boosting technology adoption. Where labor shortages led to the adoption of labor-saving machines, technology afterwards improved more rapidly.
