    Study Notes

    Chapter 11: Sharing Economy, Collaborative Consumption, and Efficient Markets through Tech

    • Tech facilitates connections between diverse product/service providers and consumers, offering greater reach and efficiency.
    • Efforts enable "citizen suppliers," where product owners become rental providers (e.g., rooms – Airbnb, cars – Turo, boats – Boatsetters).
    • A new class of micro-entrepreneurs provides personal services like car rides (Uber), pet sitting (Rover), meal prep (Feastly), home services (Care.com).
    • Some firms buy inventory and rent (Rent the Runway, Zipcar, Chegg).
    • Collaborative consumption involves individuals using products for a period then returning them for others' use.
    • Consumers collaborate as financiers, pooling capital for projects (Kickstarter, GoFundMe) and loans (LendingClub).
    • Internet-enabled market makers, rooted in eBay and Craigslist, facilitate these transactions.

    Goods and Services

    • Goods include pre-owned items (eBay, Craigslist, ThredUP), loaner products (Zilok, Rent the Runway, Chegg), and custom products (Etsy).
    • Services encompass professional (Upwork, crowdSPRING) and personal services (Angie's List, Handy, TaskRabbit).
    • Additional services include delivery (DoorDash, Grubhub), transportation services (Uber, Lyft, Didi), and loaner vehicles (Turo, Zipcar).
    • Places to stay are listed on platforms like Airbnb, HomeAway, and Couchsurfing. Office spaces are available on platforms like LiquidSpace and ShareDesk.

    Social Media and Sharing Economy Growth

    • Word-of-mouth referrals via social media accelerate sharing economy growth (47% of participants learned via word-of-mouth, 91% recommend services to friends).
    • Social proof (others doing it) influences participation.
    • Platforms like Uber connect drivers and customers directly through social media accounts.

    Chapter 15: Open Source, Cloud, Virtualized, and App-Driven Shifts

    • Marginal Costs: For software products, marginal cost is zero (MC = 0).
    • Open Source Software (OSS): Free software, allowing users to view and potentially modify code.
    • Cloud Computing: Shifting to services delivered over the internet instead of individual hardware.
    • Software as a Service (SaaS): Third-party software subscription service.
    • Virtualization: Creating multiple virtual computers on a single physical one.
    • Linux: A broadly utilized open-source operating system.
    • LAMP: Popular stack for web servers (Linux, Apache, MySQL, PHP).

    Chapter 19: Information Security

    • Data breaches: Significant data breaches like the 2017 Equifax breach highlight concerns about information security.
    • Target hack: Hackers exploited vulnerabilities in an open-source component (Apache Struts) to gain unauthorized access to Target's systems.
    • Information security is vital in the modern world, especially for large firms dealing with large amounts of client data.

    Technology & Security

    • Security: Vulnerabilities in software (e.g., Heartbleed), malicious actors, and insufficient data security measures are crucial concerns.
    • Malware: Malicious software (viruses, worms, and Trojans) poses significant risks to digital systems.
    • Security measures: Implementing security safeguards like firewalls, intrusion detection systems, and network monitoring is critical for protecting systems from attacks.
    • User precautions: Users should follow security best practices to protect their personal data and utilize appropriate security software.
