A factory produces two types of toys: robots and cars. The factory can produce 50 robots and 100 cars per day. The demand for robots is represented by the equation p = 10 - 0.05q, where p is the price in dollars and q is the quantity demanded. The demand for cars is represented by the equation p = 15 - 0.1q.
What is the equilibrium price and quantity for each toy? How would a decrease in the cost of production affect the equilibrium price and quantity for each toy? Show your calculations and explain the concept behind the changes in equilibrium.

To find the equilibrium price and quantity for each toy, we need to set the quantity demanded equal to the quantity supplied for each toy.
For robots, the quantity supplied is 50 per day, so we have:
Quantity supplied = Quantity demanded
50 = 10 - 0.05q
0.05q = 40
q = 800
So the equilibrium quantity for robots is 800 per day. To find the equilibrium price, we can substitute this quantity into the demand equation:
p = 10 - 0.05q
p = 10 - 0.05(800)
p = 10 - 40
p = -30
This result doesn't make sense, as we can't have a negative price. This means that the demand and supply curves don't intersect at a positive price for robots, so there is no equilibrium price for this toy.
For cars, the quantity supplied is 100 per day, so we have:
Quantity supplied = Quantity demanded
100 = 15 - 0.1q
0.1q = 85
q = 850
So the equilibrium quantity for cars is 850 per day. To find the equilibrium price, we can substitute this quantity into the demand equation:
p = 15 - 0.1q
p = 15 - 0.1(850)
p = 15 - 85
p = -70
Again, this result doesn't make sense, so there is no equilibrium price for cars either.
Now, let's consider how a decrease in the cost of production would affect the equilibrium price and quantity for each toy. If the cost of production decreases, the supply curves for both toys would shift to the right, as the factory can produce more toys at the same cost. This means that the equilibrium quantity for each toy would increase, but the effect on the equilibrium price would depend on the elasticity of demand for each toy.
For robots, we don't have an equilibrium price, so we can't analyze the effect of a decrease in the cost of production on the price. However, we can say that the increase in quantity supplied would not be enough to reach a positive equilibrium price, as the demand for robots is relatively inelastic (the coefficient of q in the demand equation is -0.05, which is less than 1 in absolute value).
For cars, the demand is more elastic (the coefficient of q in the demand equation is -0.1, which is greater than 1 in absolute value), so a decrease in the cost of production would lead to a larger decrease in the equilibrium price, as consumers are more responsive to price changes. The equilibrium quantity would still increase, but the effect on the price would be more pronounced.
In summary, we can't find an equilibrium price for robots and cars in this scenario, but we can analyze the effect of a decrease in the cost of production on the equilibrium quantity and price for each toy. The elasticity of demand plays a crucial role in determining the magnitude of the price change in response to a change in supply.

Can you explain the concept of elasticity of demand in more detail?
user
Sure, elasticity of demand is a measure of how responsive consumers are to changes in price. More specifically, it measures the percentage change in quantity demanded in response to a one percent change in price. If the demand for a good is relatively elastic, this means that consumers are very sensitive to changes in price and will adjust their purchases accordingly. On the other hand, if the demand for a good is relatively inelastic, this means that consumers are less sensitive to changes in price and will continue to purchase roughly the same amount even if the price changes.

There are a few factors that can affect the elasticity of demand for a good. One important factor is the availability of substitutes. If there are many substitutes available, consumers will be more likely to switch to a different product if the price of their preferred product increases, making demand more elastic. Another important factor is the proportion of income that the good represents. If a good represents a larger proportion of a consumer's income, they will be more likely to reduce their consumption if the price increases, making demand more elastic. 

Another way to think about elasticity of demand is in terms of the shape of the demand curve. A flatter demand curve indicates that demand is more elastic, as a small change in price will result in a relatively large change in quantity demanded. Conversely, a steeper demand curve indicates that demand is more inelastic, as a large change in price will only result in a small change in quantity demanded.

Understanding elasticity of demand is important for businesses and policymakers, as it can help them anticipate how consumers will react to changes in price and make informed decisions about pricing strategies and policies.
