How would 'Standard Oil' respond to an expected change in oil prices?
Supply decreases if a price hike is expected
Supply increases if a fall in price is expected
If a price hike is expected, a firm would supply less and store for the future. If a fall in price is expected, a firm would supply more to sell out its stock. Both choices are driven by a desire to maximize profit. In contrast, a consumer would by more when there is an expected price hike and buy less when there is an expected fall in price.
