We study the impact of nationalism and interstate frictions on international economic relations by analyzing market reaction to adverse shocks to Sino-Japanese relations in 2005 and 2010. Japanese companies with high China exposure suffer relative declines during each event window; a symmetric effect is observed for Chinese companies with high Japanese exposure. The effect on Japanese companies is more pronounced for those operating in industries dominated by Chinese state-owned enterprises, whereas firms with high Chinese employment experience lower declines. These results emphasize the role of countries' economic and political institutions in mediating the impact of interstate frictions on firm-level outcomes.

We study the wealth accumulation of Indian state politicians using public disclosures required of all candidates. The annual asset growth of winners is 3–5 percent higher than that of runners-up, a difference that holds also in a set of close elections. The relative asset growth of winners is greater in more corrupt states and for those holding ministerial positions. These results are consistent with a rent-seeking explanation for the relatively high rate of growth in winners’ assets.
