Theories of Profit

Gross Profit and Net Profit

Gross profit is the total surplus an entrepreneur receives from running a business, before any deductions. It is not a pure return to entrepreneurship alone, because it typically includes implicit payments the entrepreneur is really making to themselves in other capacities — wages of management (for the entrepreneur's own labour of organising the business), interest on their own capital invested in the business, and rent on any premises they own and use. Once these implicit factor payments are deducted, what remains is net (or pure) profit — the true reward for entrepreneurship and risk-taking as a distinct function.

Dynamic Theory of Profit (J.B. Clark)

J.B. Clark argued that in a hypothetical static economy — one with no changes in population, capital stock, technique, consumer tastes, or business organisation — competition would eventually eliminate pure profit altogether, because every factor (including entrepreneurship) would be paid exactly its marginal productivity, with nothing left over. Pure profit, in Clark's view, arises only in a dynamic economy that is constantly changing: growth in population and capital, improvements in technique, shifts in consumer demand, and new forms of business organisation continually create temporary gaps between costs and revenues, and profit is the surplus that flows to the entrepreneur who successfully exploits these changes before competition catches up.

Innovation Theory of Profit (Schumpeter)

Joseph Schumpeter placed innovation at the centre of profit theory. He argued that profit is the reward earned specifically by the entrepreneur who introduces genuine innovations — a new product, a new method of production, the opening of a new market, a new source of raw material, or a new form of business organisation. The innovating entrepreneur temporarily enjoys a monopoly-like advantage and earns profit above the normal competitive return; but as rivals imitate the innovation, this profit is gradually competed away, until the next wave of innovation creates fresh profit opportunities. In Schumpeter's view, profit and innovation are thus permanently linked, with profit acting as the incentive that drives entrepreneurs to keep innovating.

Risk-Bearing Theory (Hawley)

F.B. Hawley argued that profit is the reward for bearing business risk. Every business venture involves risks — that a new product will not sell, that demand will fall, or that costs will rise unexpectedly — and someone must bear these risks in exchange for the possibility of a return. Hawley held that the entrepreneur bears these risks as the price of undertaking production, and profit is the compensation for doing so; a higher-risk venture should, on average, promise a higher expected profit.
