The study looked at how changes in exchange rates affect prices in Uruguay and Chile. They found that in Uruguay, the government's credibility in managing the economy plays a big role in how much prices change. When the government is more trustworthy, prices don't go up as much when the exchange rate changes. In Chile, people expect prices to stay stable, and the government doesn't need to do much to keep them that way. So, in summary, in Uruguay, the government needs to work on both building trust and stabilizing the exchange rate to keep prices in check.
