Research question: effect of economic integration on environmental policy, with attention to joint impact of trade openness and political uncertainty.
Core theoretical predictions:
- "The effect of trade integreation on the environment is conditional on the degree of political uncertainty."
- "Trade integration raises the stringency of environmental policies, but the effect is reduced when the degree of political uncertainty is great."
- "Political uncertainty has a positive effect on environmental policy as it reduces lobbying efforts."
Model features and terminology preserved from source: trade openness, political uncertainty, lobbying, lobby group, incumbent government, government turnover, utility function, policy choice, producer lobby.

Data: "a unique data set of primarily developing countries."
Main empirical result: "The empirical findings support the theory and are robust under alterntive specifications."
Robustness: findings remain under alternative specifications (as stated in source).

Trade liberalization tends to increase environmental-policy stringency, but:
- The strengthening effect of trade on environmental policy is attenuated when political uncertainty is high.
- Political instability can reduce lobbying pressure, which may paradoxically improve environmental policy outcomes.
Relevant policy considerations:
- Account for political uncertainty when assessing environmental impacts of trade integration.
- Consider interactions between trade policy, political stability, and domestic lobbying dynamics when designing environmental regulations.
