Business Objectives in IB Economics: Why Firms Don't Always Profit-Maximise
Target Question:
What are the alternatives to profit maximisation in IB Economics?
Today, let's talk about business objectives. The real objectives - not the typical "We care about our customers" slogan painted across the side of a delivery van, but what firms actually aim for when they are on the market.
This entry is the producer-side companion to our behavioural economics series. Our previous rational consumer choice entry covers the standard model of the consumer; our bounded self-control entry covers why real consumers usually break that model. This entry asks the same question of firms: the standard model says firms maximise profit - but are they always in the market to maximise profit? And when they aren't, what are they doing instead?
IB Economics HL students: business objectives is HL-only content, it appears regularly in Paper 1 extended responses, and the profit/revenue maximisation calculations feature in Paper 3 -

The Classic Assumption: Profit Maximisation
IB Economics Definition - Profit Maximisation:
Profit maximisation occurs at the level of output where marginal revenue equals marginal cost (MR = MC). At this output, producing one more unit would add more to cost than to revenue, and producing one fewer would sacrifice more revenue than it saves - so total profit is at its maximum.
Traditionally, economic theory assumed firms had only one priority: profit. And in fairness, it's a solid theory. Profit maximisation happens when the gap between total revenue and total cost is as wide as the gap between a grade 4 and a grade 7 in IB Economics.
Mathematically, it's that point where MR = MC - marginal revenue equals marginal cost.
Why there? Because:
If MR is greater than MC, each extra unit sold adds more money than it costs to make - and to keep producing.
If MC is greater than MR, you're losing money on each extra unit - time to hit the brakes.
At MR = MC, you're balanced perfectly: no profitable expansion left, no loss-making units produced. Source: IB Economics Diagrams
This is the condition you'll need to identify on the diagram in Paper 1 and apply in Paper 3 calculations.
IB Economics real-life example: Apple doesn't decide to produce 74 million iPhones in a quarter because it feels right. Its output is modelled so that, ideally, the cost of making one more phone roughly equals the extra revenue it brings in. They maximise profit by moving carefully along that MR = MC line - with maybe a touch of "creativity" from the pricing team.

But Is Profit the Only Goal? The HL Critique
No - and this is where the HL critique of maximising behaviour begins. Businesses are run by people, not robots (yet), and people have all sorts of motivations. There is also a structural reason firms at times move away from profit maximisation: in large companies, the managers who make output and pricing decisions are not the shareholders who receive the profit. Managers may care about sales figures, company size, or their own working conditions - objectives that diverge from pure profit. The IB Economics 2022-2026 syllabus identifies four alternative objectives, and each implies a different decision about output and price.
1. Revenue Maximisation: Where MR = 0
IB Economics Definition - Revenue Maximisation:
Revenue maximisation occurs at the level of output where marginal revenue equals zero (MR = 0). Beyond this point, selling additional units actually reduces total revenue. A revenue-maximising firm produces more output and charges a lower price than a profit-maximising firm - accepting lower profit in exchange for greater sales.
This is the alternative objective with its own precise diagram position - and the contrast with profit maximisation is a classic Paper 1 HL point. Total revenue keeps rising as long as each additional unit adds something to revenue, i.e. as long as MR is positive. Revenue peaks exactly where MR = 0. Since MR = 0 always lies at a higher output than MR = MC (marginal cost is positive, so MR must still be positive at the profit-maximising point), the revenue maximiser produces more and charges less than the profit maximiser. Source: IB Economics Diagrams
Why would a firm deliberately sacrifice profit for revenue? Three reasons appear in the IB Economics syllabus that can be used as response: managers' pay and prestige are often tied to sales rather than profit; high sales volumes can deter potential entrants by signalling a crowded market; and lenders and investors frequently judge firms by revenue growth, especially in young industries. On the diagram, learn both positions: profit maximisation at MR = MC, revenue maximisation at MR = 0. Being able to mark both on the same diagram - and explain why output is higher and price lower at the second. The full diagram set is in Source: IB Economics Diagrams Unit 7.
2. Growth Maximisation
IB Economics Definition - Growth Maximisation:
Growth maximisation is a business objective in which a firm prioritises expanding its scale - sales, capacity, and market presence - over current profit. Growth can reduce long-run average costs through economies of scale and strengthen future market position, but it typically requires sacrificing short-run profit through reinvestment.
Bigger is often seen as better in business. Companies aim to grow sales, expand into new markets, and reduce average costs through economies of scale - accepting lower profit today in exchange for a stronger position tomorrow.
IB Economics real-life example: Tesla expanding production in Germany, Texas, and China. The goal wasn't current profit - it was future dominance. But one thing is what firms plan, another very different thing is how it turns out: intense competition from Chinese manufacturers has shown that growth strategies carry genuine risk, and scale alone guarantees nothing. That caveat - planned objective versus realised outcome - is itself a useful evaluation point you can use.
3. Market Share
Sometimes the short-term objective is simply grabbing a bigger slice of the pie - even at the cost of current profit. Market share connects closely to both revenue and growth maximisation: a firm pricing low and producing high to win market share is, in diagram terms, operating much closer to the revenue-maximising output than the profit-maximising one. Source: IB Economics Diagrams
IB Economics real-life example: Amazon spent years reinvesting essentially all of its profits to dominate market share. What is behind this decision? once you're the biggest player, you can begin to harvest profits, shape the rules of the game, and squeeze smaller competitors.
The formula, which appears in Paper 3:
Market share = (Firm's total sales revenue ÷ Industry's total sales revenue) × 100
Try it with a few fast fashion brands - you'll be surprised how much of the market is controlled by a handful of players.
4. Satisficing: Good Enough on Purpose
IB Economics Definition - Satisficing:
Satisficing, a concept developed by Herbert Simon, describes the pursuit of a satisfactory rather than optimal outcome. A satisficing firm aims for an acceptable level of profit - enough to cover costs, reward owners adequately, and sustain the business - rather than the maximum possible. It is bounded rationality applied to the producer.
This is the anti-perfectionist approach - and the most direct bridge between this entry and the consumer-side critique blog entry. Herbert Simon, the same economist behind bounded rationality, observed that real decision-makers - firms as much as consumers - settle for "good enough" outcomes. Calculating the true profit-maximising output requires information about cost and demand curves that real firms rarely have access to; and even when they could push harder, owners may rationally prefer a sustainable, more comfortable outcome to a daily exhausting battle that may bring an optimal position.
Imagine a local coffee shop run by a couple who would rather enjoy a relaxed lifestyle in a sunny location than double their hours for marginally more profit. That's a good satisficing example - and it is not irrational. It is a deliberate trade of their time for money, made with full awareness. The rational producer model has no room for that trade; the behavioural critique does. If you've read our bounded self-control entry, you'll recognise the balance: Simon's bounded rationality limits consumers and producers alike.
5. Corporate Social Responsibility (CSR)
IB Economics Definition - Corporate Social Responsibility:
Corporate social responsibility (CSR) is a business objective in which a firm deliberately incorporates social and environmental goals into its decision-making, beyond what the law requires. CSR may reduce short-run profit but can raise long-run profitability through customer loyalty, employee retention, brand value, and reduced regulatory and reputational risk.
This is where a business says: let's not just make money - let's do good while we're at it. CSR means reducing carbon emissions, improving workers' conditions, giving back to the community. And it can pay off in the long run: respected businesses tend to attract loyal customers, talented employees, and investor confidence.
IB Economics real-life example: Patagonia makes outdoor gear and donates 1% of sales, plus time and services, to environmental causes - and remains profitable. Doing the right thing can be good business strategy.
Good IB Economics HL students should focus on providing two specific evaluation points. Is CSR a true alternative objective - a firm accepting permanently lower profit in exchange for social goals? Or is it a long-run profit strategy - a short-run cost incurred for a long-run gain in brand value and customer loyalty? The same observable behaviour fits both interpretations, which is exactly why CSR makes such a productive Paper 1 discussion: a sceptic can argue it is profit maximisation with better marketing; a CSR supporter can point to firms (Patagonia among them) that have made structural commitments going well beyond branding payoff.
IB Economics Summary
Businesses don't always behave the way your IB Economics textbook model suggests. Profit maximisation at MR = MC remains the benchmark - the position against which every alternative is measured, and the one you must be able to identify on the diagram. But real firms play with multiple objectives: revenue and market share when building position, growth when scale promises future advantage, satisficing when owners value sustainability over optimisation, and CSR when reputation and values enter the calculation.
And just like people, businesses evolve. A start-up might chase market share now and dream of profits later; a giant corporation might shift from aggressive growth to CSR to keep investors and regulators content. The skill required from students in possible exam answers is to match the objective to the evidence: a firm producing beyond MR = MC and pricing low is telling you something about which their maximising objective really is.
Something to take with you: do you think a business can truly do good while still maximising profits - or is CSR just clever branding in disguise without any real substance?
Frequently Asked Questions - Business Objectives (IB Economics HL)
What are the alternatives to profit maximisation in IB Economics?
The HL syllabus covers four main alternatives: revenue maximisation (producing where MR = 0), growth maximisation (prioritising expansion over current profit), satisficing (targeting a satisfactory rather than maximum profit), and corporate social responsibility (incorporating social and environmental goals into decisions). Each implies a different output and price from the profit-maximising MR = MC position.
What is the profit maximisation condition in IB Economics?
A firm maximises profit where marginal revenue equals marginal cost (MR = MC). If MR exceeds MC, expanding output adds more to revenue than cost; if MC exceeds MR, the last units cost more than they earn. Only at MR = MC can profit not be increased by changing output. This condition appears in Paper 1 diagrams and Paper 3 calculations.
What is the difference between profit maximisation and revenue maximisation?
Profit maximisation occurs at MR = MC; revenue maximisation at MR = 0. Because MR = 0 lies at higher output than MR = MC, the revenue maximiser produces more and charges less than the profit maximiser. Firms pursue revenue maximisation to build market share, deter entrants, or because managerial pay and status track sales rather than profit.
What is satisficing in IB Economics?
Satisficing, developed by Herbert Simon, is the pursuit of a satisfactory rather than optimal outcome - a firm targeting acceptable profit rather than maximum profit. It reflects bounded rationality applied to producers: calculating the true optimum requires information firms rarely have, and owners may rationally prefer a sustainable outcome to an exhausting optimal one.
Is corporate social responsibility compatible with profit maximisation?
It depends on the interpretation - which is what makes it a strong evaluation question. CSR reduces short-run profit through higher costs, but can raise long-run profitability through loyalty, brand value, and reduced regulatory risk. The key distinction is between CSR as a genuine alternative objective (permanently lower profit accepted for social goals) and CSR as a long-run profit strategy. The same firm behaviour can support either reading.
