What is the digital economy?
The digital economy means all the buying, selling and working that happens through the internet, phones, computers and data.
- Shopping online, paying by phone, booking a taxi in an app, watching paid videos.
- Firms use software to make, sell and deliver goods and services.
Information can be copied and sent almost free. So one good app can serve millions of people at very low extra cost.
Platforms and the network effect
A platform is a meeting place on the internet. It links two groups: buyers and sellers, riders and drivers, guests and hotels. It does not always own the goods. It earns a fee (commission) or money from ads.
The network effect: a platform becomes more useful when more people use it. More buyers attract more sellers, which attract more buyers. That is why a few big platforms often win a whole market.
Good and bad sides
- Good: more choice, lower prices, small sellers reach the whole country, new jobs (delivery, app work).
- Bad: one platform can become too powerful, gig workers may lack job security, and local shops may lose customers.
Mobile use, social networks and online reviews
Most people now go online by mobile phone. They search, compare, book and pay in a few taps.
Social networks and online communities let customers share photos, tips and complaints. A review is a written opinion; a rating is a score (often 1 to 5 stars).
- Many customers read reviews before they buy.
- A firm should answer reviews politely, fix real problems and never post fake reviews.
Digital identity of a business and personal data
A business's digital identity (e-reputation) is how it looks online: its website, app, social pages, map listing, photos and reviews. It should be honest, up to date and the same everywhere.
Personal data is any information about a person: name, phone, location, what they buy. Platforms collect it to suggest products and show ads.
- Firms must ask for consent, collect only what they need, keep it safe and delete it when asked.
- Laws such as the EU GDPR and India's Digital Personal Data Protection Act 2023 set these rules.
Key formulas and definitions
- Platform: an online meeting place that links two groups of users
- Network effect: the more users, the more useful the platform
- Commission income = number of orders × order value × fee %
- Possible links between n buyers and n sellers = n × n
- Digital identity (e-reputation) = how a business appears online
- Personal data: any information that can identify a person
- Consent: clear permission before data is collected
Worked examples
1. A food app has 200 orders a day, each worth ₹400, and takes a 15% fee. Find its daily fee income.
200 × 400 = ₹80,000 of orders. 15% of 80,000 = ₹12,000 a day.
2. A platform grows from 5 sellers and 5 buyers to 10 and 10. How many possible buyer–seller links are there before and after?
Before: 5 × 5 = 25. After: 10 × 10 = 100. Users doubled, but links became 4 times. This is the network effect.
3. A small hotel has a 3.1-star rating and many complaints about slow Wi-Fi. What should it do for its digital identity?
Fix the Wi-Fi first, then reply politely to the reviews saying what was fixed, update photos and details on its website and map listing, and ask happy guests to leave honest reviews. It should never buy fake reviews.
Common mistakes
- Thinking a platform must own the goods it sells. Most platforms only link buyers and sellers.
- Believing more users only add value one by one. The network effect makes value grow faster than the number of users.
- Treating reviews as free advertising to fake. Fake reviews break trust and are illegal in many countries.
- Thinking personal data is only your name. Location, shopping history and photos are personal data too.
