Final answer:
The World Trade Organization has expanded the market for Washington State cherries by reducing trade barriers, potentially increasing demand. However, weather changes affect production costs and supply. Federal subsidies and mechanization make American grain like wheat competitive in the global market.
Step-by-step explanation:
The World Trade Organization (WTO) has played a significant role in the trade of agricultural products, such as Washington State cherries. Due to the WTO's efforts to reduce trade barriers and subsidies, more countries can competitively enter the market. This can lead to an increase in the number of customers for Washington State cherries, potentially boosting demand. However, changes in weather and climate, such as droughts, can significantly affect the cost of production and supply of these agricultural products, thus impacting the quantity supplied at any given price.
Conversely, especially favorable weather conditions can result in an increased supply, shifting the supply curve to the right. Within the context of agricultural trade, American grain, including wheat, benefits from both mechanization and federal subsidies, making it more competitive in the global market. Nevertheless, this could raise concerns among developing countries about the long-term impacts of open trade on their agricultural sectors due to the competition with highly subsidized and efficient American produce.
