The researchers used a new model to look at how different policies could impact different regions in the Philippines. They found that changing tariffs in agriculture might hurt some regions' businesses but still make everyone better off. By investing a lot in improving how products are sold, the country could see bigger benefits, even if they're not spread evenly. Combining changes in trade rules with better marketing could soften the bad effects of the trade changes. However, the two policies might not work together as well as expected, meaning they could be pursued separately for better results.
