Determinants of a Rational Producer's R&D Decision

Question

Firms are protected by intellectual property laws when they successfully develop new technology or products from Research & Development (R&D). However, they often do not invest sufficient resources and hence governments need to play a critical role to encourage more R&D.

Explain the determinants of a rational producer’s decision on whether to invest in R&D. [10]

Answer

A producer is a rational economic agent whose goal is to maximise profit. Under the rational decision-making framework, it weighs the expected benefits and costs of investing in R&D against its constraints, its information, and the likely perspectives of other agents before deciding to proceed. This answer applies that framework to the decision to invest in R&D, covering the cost–benefit calculation first and then the further considerations that condition it.

Benefits. Because the producer is profit-maximising, the benefits of R&D are measured in profit. R&D taking the form of product innovation improves the quality of goods and services, which raises demand by making the product more desirable and makes that demand more price-inelastic by making the product less substitutable — both of which raise revenue. For example, Apple’s continued investment in innovating the iPhone has improved its quality and made it more desirable and distinctive. R&D taking the form of process innovation instead makes production more efficient and so lowers unit cost of production: Amazon’s investment in automating its packaging processes cuts the wage cost otherwise incurred, lowering its unit cost. Higher revenue or lower unit cost both raise profit.

Costs. Against this the producer weighs the explicit and implicit costs of R&D. Explicit costs are the monetary outlays — set-up fees, transport, raw inputs and rental; if these exceed the additional revenue R&D would bring, the firm will not undertake it. Implicit costs are the opportunity cost of the resources committed: the time, money and labour devoted to R&D could have funded an alternative profit-raising strategy such as product proliferation, and the profit that alternative would have brought is forgone. A rational producer invests only where the expected benefit exceeds the sum of these costs.

Beyond the core cost–benefit calculation, three further determinants condition the decision.

Constraints. The producer must be able to act on a favourable cost–benefit verdict. Budget constraints (insufficient financial capital to fund R&D), time constraints (insufficient time to complete the research and reap its returns) and resource constraints (insufficient research facilities or manpower) can leave a firm willing but unable to invest. Where a constraint cannot be overcome, the producer postpones or cancels the investment; where it can, the remaining factors decide.

Information. A rational decision requires adequate information on the expected costs, benefits, constraints and unintended consequences of R&D. With imperfect information the producer cannot accurately estimate its rate of return — its marginal efficiency of investment (MEI) — and may postpone the decision until it has gathered more. For instance, a firm uncertain of the total explicit cost of an R&D venture cannot price its expected returns and may defer it.

Perspectives. Finally the producer anticipates the reactions of other agents. If rival producers are positioned to free-ride on its innovation, it may delay until it can patent and protect the result. If the government is expected to support R&D through innovation grants, the producer is more willing to invest, since this lowers its net cost. And if consumers’ tastes and preferences are difficult to shift — owing to salience bias or the sunk-cost fallacy — the projected MEI of the innovation falls, again prompting postponement or cancellation.

In sum, a rational producer invests in R&D when the expected profit benefit outweighs its explicit and implicit costs, provided its constraints can be overcome, it holds sufficient information, and the anticipated responses of rivals, government and consumers do not undermine the expected return.
