    The idea

    The digital economy transforms how market information is accessed. Price comparison sites reduce information asymmetry by allowing consumers to easily compare prices across suppliers. This increases price elasticity of demand and intensifies competition, forcing firms to be efficient. Viral marketing leverages digital networks to rapidly spread promotional messages through user sharing, offering a cost-effective way to build brand awareness. Social media platforms provide firms with vast consumer data for targeted advertising and enable direct customer engagement.

    For example: A brand might use social media analytics to target demographics with a viral campaign, while consumers use comparison sites to find the best deal on those products.

    What earns the marks

    • Explanation of how price comparison sites reduce information asymmetry for consumers.
    • Analysis of the impact of viral marketing on a firm's promotional costs and brand reach.
    • Evaluation of how social media allows firms to gather market information and target specific consumer segments.
    • Assessment of how increased market information in the digital economy affects price elasticity of demand and competition.

    Common mistakes and how to put them right

    • Assuming viral marketing is always successful and cost-free.

      Put it right: It requires initial investment in content creation and carries the risk of negative publicity spreading rapidly.

    • Stating that price comparison sites benefit firms by allowing them to charge higher prices.

      Put it right: They typically increase competition and drive prices down by empowering consumers.

    • Confusing social media marketing with traditional advertising.

      Put it right: Social media allows for two-way engagement and data-driven targeting, unlike traditional broadcast media.

    Exam tips

    • When discussing price comparison sites, explicitly mention the reduction of information asymmetry and its effect on market efficiency.
    • Evaluate the risks associated with viral marketing, such as loss of control over the brand message, to demonstrate balanced analysis.
    • Use specific examples of how firms utilise social media data to tailor their products or marketing strategies to specific demographics.

    A top-down flowchart. The digital economy node branches into three nodes: price comparison sites, viral marketing and social media. Price comparison sites lead to reduced information asymmetry, which leads to higher price elasticity of demand, which leads to intensified competition. Viral marketing leads to promotional messages spreading through user sharing. Social media leads to two nodes: consumer data for targeted advertising, and direct customer engagement.
