Findings indicate that the international price of rice exerts significant negative effects on the volatility of domestic rice prices in Burundi and Tunisia, and significant positive effects in Chad and Sri Lanka; in addition, international wheat prices have significant negative effects on the volatility of domestic wheat prices in Brazil and Mauritania; further, international prices for maize exert significant effects on the volatility of domestic maize prices in the Dominican Republic, Niger and the Philippines.
