Firms can expand production and profitability in three ways.
A firm can continue making the same range of products, but can increase the scale of
its production, and hopefully utilise economies of scale.
Economies of scale refers to the fact that as a firm increase the amount of a good it produces,
the cost per unit falls. ''The more you make, the cheaper each item gets''.
A firm can develop new products, and increase the range of its production as well as the
amount.
A firm can take over other firms and use the productive capacity of these firms to expand
the quantity and range of production.
