Price will increase
WHAT
Yes, you can. When the cross-price elasticity between two goods is positive, they are more likely substitutes in consumption; when it is negative, they are more likely complements. A cross-price elasticity of 0 implies no correlation.
Substitutes
Yes
Price will increase
WHAT
the indifference curve has its usual negatively sloping shape
Yes, you can. When the cross-price elasticity between two goods is positive, they are more likely substitutes in consumption; when it is negative, they are more likely complements. A cross-price elasticity of 0 implies no correlation.
Substitutes
Yes
Price of related goods fall into two categories: substitutes and complements. Complements are when a price decrease in one good increases the demand of another good. Substitutes are when a price decrease in one good decreases the demand for another good.
Public goods are non-excludable and non-rival in consumption whereas Private goods are excludable and rival in consumption.
Elastic goods usually have many substitutes, so changes in price will decrease demand. Inelastic goods, on the other hand, have very few substitutes, so demand isn't generally affected by price change.
If goods are perfect substitutes, a consumer will have no preference as to which one he or she will prefer and will make their decision on price alone. It is likely however that perfect substitutes would also all be sold for the same price.
