The study looked at how changes in exchange rates affect prices of imported goods in India. They found that the impact of exchange rate changes on prices is not always proportional, meaning prices don't always go up or down as much as the exchange rate changes. The researchers used a new method to analyze this relationship and found that the degree of price change varies across different types of imports. Most import prices in India don't change much when the exchange rate does, except for chemicals. This suggests that factors like market concentration play a role in how exchange rate changes affect import prices.
