Anna Lopez sells timber in a perfectly competitive market. Incomes increase and many people buy new homes the market demand curve shifts to the right. In the short run she should expect?

In the short run, as the market demand curve for timber shifts to the right due to increased incomes and home purchases, Anna Lopez can expect an increase in the price of timber. This price rise will lead to higher revenues for her business, allowing her to potentially increase production to meet the higher demand. However, since the market is perfectly competitive, any increase in profits will attract new firms, eventually bringing the price back down to the equilibrium level in the long run.
