Question

Спрос населения на картофель характеризуется следующими показателями эластичности: по цене -0,6; по доходу 0,8. В будущем общий уровень цен не изменится, доход населения увеличится на 4% и цена картофеля возрастет на 5%. Определите, на сколько изменится величина спроса на картофель.

Answer 1

В результате роста дохода спрос увеличится на 0,8 х 4 = 3,2%
в результате увеличения цены спрос сократится на 0,6х5 = -3%
значит общее изменение - спрос вырастет на 0,2%

Answer 2

Calculation of the Change in Demand for Potatoes

To determine the change in demand for potatoes, we need to consider the price elasticity of demand and income elasticity of demand.

The price elasticity of demand for potatoes is given as -0.6, which means that a 1% increase in the price of potatoes will result in a 0.6% decrease in demand. Similarly, a 1% decrease in the price of potatoes will result in a 0.6% increase in demand.

The income elasticity of demand for potatoes is given as 0.8, which means that a 1% increase in income will result in an 0.8% increase in demand for potatoes. Similarly, a 1% decrease in income will result in an 0.8% decrease in demand for potatoes.

Based on the given information, the future scenario is as follows: - The overall price level will not change. - The income of the population will increase by 4%. - The price of potatoes will increase by 5%.

Calculation of the Change in Demand for Potatoes due to Income Increase

To calculate the change in demand for potatoes due to the increase in income, we can use the income elasticity of demand. The income elasticity of demand is given as 0.8, which means that a 1% increase in income will result in an 0.8% increase in demand for potatoes.

Given that the income of the population will increase by 4%, we can calculate the change in demand for potatoes as follows: Change in demand for potatoes = Income increase * Income elasticity of demand Change in demand for potatoes = 4% * 0.8 Change in demand for potatoes = 3.2%

Therefore, the increase in demand for potatoes due to the increase in income will be 3.2%.

Calculation of the Change in Demand for Potatoes due to Price Increase

To calculate the change in demand for potatoes due to the increase in price, we can use the price elasticity of demand. The price elasticity of demand is given as -0.6, which means that a 1% increase in the price of potatoes will result in a 0.6% decrease in demand.

Given that the price of potatoes will increase by 5%, we can calculate the change in demand for potatoes as follows: Change in demand for potatoes = Price increase * Price elasticity of demand Change in demand for potatoes = 5% * -0.6 Change in demand for potatoes = -3%

Therefore, the decrease in demand for potatoes due to the increase in price will be 3%.

Overall Change in Demand for Potatoes

To determine the overall change in demand for potatoes, we need to consider the changes in demand due to both the increase in income and the increase in price.

The increase in demand due to the increase in income is 3.2%, and the decrease in demand due to the increase in price is 3%. Therefore, the overall change in demand for potatoes can be calculated as follows: Overall change in demand for potatoes = Change in demand due to income increase + Change in demand due to price increase Overall change in demand for potatoes = 3.2% - 3% Overall change in demand for potatoes = 0.2%

Therefore, the overall change in demand for potatoes is an increase of 0.2%.

Please note that these calculations are based on the given information and assumptions about the price elasticity of demand and income elasticity of demand for potatoes.
