In this section we explore the main drivers that help a firm expand its size, market share and profits. Think of a firm as a plant: the more sunlight, water and nutrients it gets, the taller it grows. Each factor below is a different “nutrient” that fuels growth.
When a firm can set prices above marginal cost, it earns economic profits that can be reinvested.
Producing more units reduces the average cost: “bulk buying” and “spreading fixed costs”.
\$\text{Average Cost} = \frac{FC + VC(Q)}{Q}\$
New products and processes create competitive advantage and open new markets.
Capital from banks, venture capital or equity markets allows firms to invest in growth.
Collaborations can provide new distribution channels or complementary skills.
Entering new geographic markets increases sales volume.
Tax breaks, subsidies and regulatory support can lower costs.
Combining firms can instantly increase scale, eliminate competition and acquire new capabilities.
Automation, AI and digital platforms reduce costs and improve efficiency.
