Practise supply-shift questions by moving the curve left or right and linking the shift to new equilibrium price and quantity.
The price of olive oil peaked in the summer of 2024, averaging € 10000 per tonne. It is expected to fall to between €4000 and €5000 per tonne in 2025.
Some of the main areas where olive oil is produced are located in Greece, Spain and Tunisia. All are set for improved harvests of olives, after years of heatwaves and droughts causing a fall in the harvest. Better weather means Greece is expected to produce 230,000 tonnes in the 2025 season, up from 130,000 tonnes the previous year. While Spain and Tunisia are also forecasting large increases in production.
With reference to the data above and your knowledge of economics, analyse how natural factors, such as favourable weather conditions, may affect the market for olive oil in 2025.

AO2 and AO3
- Possible use of a diagram:

- Natural factors, such as favourable weather could shift the supply curve outwards/to the right (from S to S1)
- Favourable weather can increase supply because it can make it easier to grow olives and therefore make it cheaper to produce olive oil
- Greece's production was expected to increase by 100,000 tonnes from the previous year in the 2025 season (Qe to Q1)
- This will therefore result in a decrease in the price (from Pe to Pl) if demand stays the same
- This is evident from the expected fall in price of olive oil by at least 50%, from € 10000 per tonne to between € 4000 and € 5000 pertonne
