Your daily economics brief, mapped to your exam board

Exam Tip: This article illustrates behavioural economics (4.1.2.3) and challenges to rational decision-making (4.1.2.1). Passengers are not consciously choosing to collide; rather, they follow ingrained cultural norms (walk on the left in Britain, on the right in continental Europe) without rational evaluation of the Heathrow context. This represents a coordination failure — individually rational behaviour (following familiar norms) creates collectively irrational outcomes (congestion). Students can use this to discuss choice architecture (4.1.2.3) and how nudges or design changes could improve efficiency. The article also relates to allocative efficiency (4.1.1.5): perfect allocative efficiency requires not just correct price signals but also coordinated behaviour. A shortage of airport capacity (scarcity, 4.1.1.4) is compounded by behavioural failures. This could support an essay on whether market mechanisms alone solve allocation problems or whether behavioural insights and institutional design are equally critical.

Exam Tip: This article illustrates market imperfections and information failure (4.1.5.6). The revelation of hidden email exchanges between a corporate leader and a criminal represents asymmetric information — stakeholders (investors, employees, customers) lacked critical information affecting their decision-making. Students could use this to discuss how moral hazard emerges when leaders' actions are not fully observable, and how information failure can damage firm objectives (4.1.4.2). The subsequent market response (resignation) shows how the price mechanism attempts to correct reputational externalities, though often imperfectly and with time lags.

Exam Tip: This article exemplifies government failure (4.1.5.9) and information asymmetry (4.1.2.2, 4.1.5.6) in public policy. When government officials share sensitive Treasury documents inappropriately, they create unequal information access that allows private actors to gain advantage in economic decision-making — a form of information failure. Students can discuss how moral hazard arises when government actors face weak accountability for misusing sensitive data. The incident illustrates unintended consequences of government intervention: fiscal and trade policy decisions (4.2.3.5) may be distorted if confidential information leaks to private interests before public announcement. This connects to how information failures prevent efficient resource allocation and fair competition.
