Final answer:
During growth, businesses can expect increased productivity, which may lead to temporary higher profits and market competition that eventually stabilizes both supply and profit levels.
Step-by-step explanation:
During a period of growth, a business can expect to experience an increase in productivity. This phase often leads to technological improvements that reduce costs of production, prompting an increase in the supply curves, both for individual firms and at the market level. As a result, existing firms tend to see higher profits temporarily, driving competition and attracting new firms to the market until profits level out to zero. Ultimately, consumers benefit from better or less expensive products, and the businesses with improved or cheaper products see increased profits, while their employees may earn higher incomes.
