Sellers expect the price of ice cream to rise in the future and, at the same time, technology improves such that consumers can make their own ice cream at home. The equilibrium price and the equilibrium quantity

The question seems to be incomplete, but I'll try to answer based on what you've given.

The scenario you've described involves two separate effects:

1. Sellers expecting the price of ice cream to rise in the future.
2. Technology improving such that consumers can make their own ice cream at home.

Let's analyze these effects separately:

1. If sellers expect the price of ice cream to rise in the future, they may choose to hold onto their current stock to sell at this higher future price. This would decrease the current supply of ice cream, which, all else being equal, would increase the equilibrium price and decrease the equilibrium quantity in the present.

2. If technology improves such that consumers can make their own ice cream at home, this would likely decrease the demand for store-bought ice cream. A decrease in demand, all else being equal, would decrease both the equilibrium price and quantity.

The overall effect on price and quantity would depend on the relative magnitudes of these two effects. If the decrease in demand due to improved technology is larger than the decrease in supply due to sellers' expectations, the equilibrium price could decrease. If the decrease in supply is larger, the equilibrium price could increase. The equilibrium quantity would likely decrease in either case, since both effects involve a decrease in either supply or demand.
