Prices at the farm level do not necessarily follow the same patterns as world prices, although market price variability is the main contributor to price risk at the farm level. These shocks are compounded by low price elasticities of supply and demand. Isolation of domestic markets from international price fluctuation, through high transactions costs, or government policies that stabilise prices for producers and/or consumers, further aggravate volatility on international markets, and affect those who are most open to trade.
