*🕹️What is Stagflation🕹️*

*Stagflation is a situation in an economy where three problems happen at the same time:*
👇👇👇👇👇👇👇👇👇👇
1. *Slow economic growth (stagnation) → Economy grows very slowly or stops growing*

2. *High unemployment → Many people do not get jobs.*

3. *High inflation → Prices of goods and services keep increasing.*

Simple Definition:

*Stagflation = Stagnation + Inflation*

Example:

Suppose:

* *Prices of food, petrol, and daily goods increase rapidly*

📈* *Factories produce less goods 🏭*
* *Many people lose jobs or do not get employment ❌*

*ਸਟੈਗਫਲੇਸ਼ਨ ਕੀ ਹੈ* *ਸਟੈਗਫਲੇਸ਼ਨ ਇੱਕ ਅਰਥਵਿਵਸਥਾ ਵਿੱਚ ਇੱਕ ਅਜਿਹੀ ਸਥਿਤੀ ਹੈ ਜਿੱਥੇ ਇੱਕੋ ਸਮੇਂ ਤਿੰਨ ਸਮੱਸਿਆਵਾਂ ਹੁੰਦੀਆਂ ਹਨ:* 👇👇👇👇👇👇👇👇

1. *ਮੱਧਮ ਆਰਥਿਕ ਵਿਕਾਸ (ਸਟੈਗਨੇਸ਼ਨ) → ਅਰਥਵਿਵਸਥਾ ਬਹੁਤ ਹੌਲੀ ਹੌਲੀ ਵਧਦੀ ਹੈ ਜਾਂ ਵਧਣਾ ਬੰਦ ਕਰ ਦਿੰਦੀ ਹੈ*
2. *ਉੱਚ ਬੇਰੁਜ਼ਗਾਰੀ → ਬਹੁਤ ਸਾਰੇ ਲੋਕਾਂ ਨੂੰ ਨੌਕਰੀਆਂ ਨਹੀਂ ਮਿਲਦੀਆਂ।*
3. *ਉੱਚ ਮਹਿੰਗਾਈ → ਵਸਤੂਆਂ ਅਤੇ ਸੇਵਾਵਾਂ ਦੀਆਂ ਕੀਮਤਾਂ ਵਧਦੀਆਂ ਰਹਿੰਦੀਆਂ ਹਨ।*

ਸਧਾਰਨ ਪਰਿਭਾਸ਼ਾ: *ਸਟੈਗਫਲੇਸ਼ਨ = ਸਥਿਰਤਾ + ਮਹਿੰਗਾਈ* ਉਦਾਹਰਣ: ਮੰਨ ਲਓ: * *ਭੋਜਨ, ਪੈਟਰੋਲ ਅਤੇ ਰੋਜ਼ਾਨਾ ਦੀਆਂ ਵਸਤੂਆਂ ਦੀਆਂ ਕੀਮਤਾਂ ਤੇਜ਼ੀ ਨਾਲ ਵਧਦੀਆਂ ਹਨ* 📈* *ਕਾਰਖਾਨੇ ਘੱਟ ਵਸਤੂਆਂ ਪੈਦਾ ਕਰਦੇ ਹਨ 🏭* * *ਬਹੁਤ ਸਾਰੇ ਲੋਕ ਨੌਕਰੀਆਂ ਗੁਆ ਦਿੰਦੇ ਹਨ ਜਾਂ ਰੁਜ਼ਗਾਰ ਨਹੀਂ ਮਿਲਦਾ ❌*
