ΑΟΘ 2015: Κεφάλαιο 5ο - Τεστ 1 (Επιμέλεια: Γιώργος Καμαρινός)

The given correct answer is "Σωστό" which means "Correct" in Greek.

The correct answer is "την αύξηση της τιμής ισορροπίας και τη μείωση της ποσότητας ισορροπίας". This answer states that there is an increase in price equilibrium and a decrease in quantity equilibrium. This suggests that there is a decrease in supply and an increase in demand, leading to a higher price and a lower quantity being exchanged in the market.

The correct answer is "τη μείωση της τιμής ισορροπίας και την αύξηση της ποσότητας ισορροπίας". This is because according to the law of supply and demand, when the price of a good decreases, the quantity demanded of that good increases, leading to an increase in the quantity supplied. Therefore, there is a decrease in the equilibrium price and an increase in the equilibrium quantity.

The correct answer is "the demand increases and the supply is constant." This means that there is an increase in the quantity of goods or services that consumers are willing and able to purchase, while the quantity of goods or services that producers are willing and able to offer remains the same. This could be due to factors such as an increase in consumer income, a decrease in the price of substitute goods, or a change in consumer preferences.

The given correct answer is "Λάθος" which means "Wrong" in Greek. The explanation for this answer is not available.

The correct answer is "την αύξηση της προσφοράς του Χ και την αύξηση της ζήτησης του Ψ". This answer suggests that both the supply of X and the demand for Y are increasing.

In the given scenario, the demand is increasing while the supply remains constant. This means that there is a higher demand for the product or service, but the supply is not increasing to meet that demand. As a result, there may be a shortage in the market, leading to higher prices and potentially increased competition among consumers to obtain the limited supply.

The correct answer is "η προσφορά μειώνεται και η ζήτηση παραμένει σταθερή" (supply decreases and demand remains constant). This suggests that there is a decrease in the quantity of goods or services available in the market, while the level of consumer demand remains the same. This scenario could occur, for example, if there is a decrease in production or an increase in costs that leads to a reduction in the supply of goods, but consumer demand remains unchanged.

The correct answer is "η τιμή ισορροπίας αυξάνεται" which translates to "the equilibrium value increases." This suggests that there is a change or shift in the equilibrium state, causing the equilibrium value to increase.

If the demand for a good decreases, it will cause a decrease in the equilibrium price of the good. However, the total expenditure of consumers on the good will remain constant. This means that even though the price decreases, consumers will compensate by buying a larger quantity of the good, resulting in a stable total expenditure. Therefore, the correct answer is "μειωθεί η τιμή ισορροπίας του και να μείνει σταθερή η συνολική δαπάνη των καταναλωτών για το αγαθό" (the equilibrium price will decrease and the total expenditure of consumers will remain constant).
