Final answer:
In business, the long-term suppliers get the long-run demand forecast and are involved in the manufacturer's product development. Producers find it easier to expand production in the long term as compared to the short run.
Step-by-step explanation:
The long-term suppliers usually get the long-run demand forecast and are involved in the manufacturer's product development. On the supply side of markets, producers of goods and services typically find it easier to expand production in the long term of several years rather than in the short run of a few months.
It is because, in the short run, it can be costly or difficult to build a new factory, hire many new workers, or open new stores. However, over a few years, all of these are possible.
