Control tasks. Solution of typical tasks Products manufactured in the reporting period, thousand pieces

From the task data it is clear that we only have a turnover(- in the base period,- in the reporting period and changeprice change for each product,those. individual price indices), but there is no product quantity and product price. In order toto find the general index of turnover, we have enough data from the condition of the problem:

I pq = or 145.5%

Example 1. There is the following data on the implementation of fruits in the region:

Name of product	July		August		Settlement columns, thousand rubles
Name of product	Price for 1 kg., Rub.p 0	Sold, t. q 0	Price for 1 kg., Rub.p 1	Sold, t. q 1	p 0 q 0	R 1 q 1	p 0 q 1



Total:

Turnover index:

Volume index of trade turnover:

Price index:

Thus, the turnover in August decreased by 3.1% or 20 thousand rubles. Due to the growth in sales by an average of 8.6%, the turnover increased by 55 thousand rubles. Due to the decrease in prices by an average of 10.8%, the turnover decreased by 75 thousand rubles.

Kozma Prutkov. The fruits of thought

Sale of goods

Determine the average price change by product group.

To determine the average price change, the formula for the harmonic average index is used:

Or 101.8%.

Consequently, prices for this commodity group in 2202 in comparison with 2001 increased on average by 1.8%.

When calculating the general index of the physical volume of production (), you can use the arithmetic mean. In this case, the replacement is made in the numerator:

q 1 = i q q 0 .

Then the index will take the form:

Example 7. The plant has data on production:

Table 6.6

Product type	Production output in Q1, thousand rubles ()	Change in production output in Q2 compared to Q1,%	Calculation graphs

A		+3	1,030
B		-2,5	0,975
V		+1,2	1,012
Total		-	-

Determine by what percentage the output of the enterprise has increased.

To determine the change in the physical volume of production as a whole for the enterprise, the formula of the weighted average arithmetic index is used, since according to the condition of the problem, individual indices of the physical volume of production are known:

Consequently, the physical volume of production as a whole for the enterprise increased by 0.9%.

Calculations using index systems of missing indexes. Many economic indices are closely related to each other and form index systems. Thus, the price index is related to the index of the physical volume of trade (if we are talking about retail prices) or the physical volume of products (if we are talking about the selling prices of the enterprise), forming the following index system:

Or I p. I q = I pq.

The product of the price index by the index of the physical volume of commodity turnover or production gives the index of the physical volume of commodity turnover in actual prices, or the index of the cost of production.

The production cost index is related to the index of the physical volume of production, forming the following index system:

Or I z. I q = I zq.

The product of the production cost index by the volume index gives the production cost index.

The labor productivity index (in terms of labor costs) is related to the index of the physical volume of production (in terms of labor costs), forming an index system:

Or I q: I T = I t.

The ratio of the index of the physical volume of production to the index of labor costs is equal to the index of labor productivity.

Example 8. It is known that the physical volume of comparable products for the plant increased by 15% in the reporting period, while production costs increased by 12%. It is required to determine how the unit cost has changed.

I z. I q = I zq,

I z:

The unit cost fell 2.6%.

Example 9... It is known that the physical volume of production increased by 10%, while the volume of labor costs increased by 5%. It is required to determine how labor productivity has changed.

Using the relationship of indices

I q: I T = I t ,

calculate the missing indicator I t:

I t= 1.10: 1.05 = 1.048 or 104.8%.

Labor productivity increased by 4.8%.

Example 10. The retail trade turnover of the enterprises of Severodvinsk in 1998 amounted to 1278.7 million rubles, in 1999 - 2076.3 million rubles, the index of the physical volume of the retail trade turnover in 1999, in% of the previous year, amounted to 91%. It is required to determine how prices have changed in 1999 compared to 1998.

Let's define the index of turnover in 1999:

or 162.4%.

Using the index relationship:

I p. I q = I pq,

Let's calculate the missing indicator I p:

Or 178.5%.

Prices in 1999 compared to the previous year in retail grew by 78.5%.

Indices of average values: constant, variable composition and structural changes. All the indices discussed above were calculated for several goods sold in one place, or types of products produced at one enterprise. Consider cases when one product is sold in several places or one type of product is produced at a number of enterprises.

If only one type of product is sold, it is quite legitimate to calculate its average price in each period, Variable composition index is the ratio of two averages obtained:

This index characterizes not only the change in individual prices at points of sale, but also the change in the structure of sales by retail or wholesale trade, markets, cities and regions. To assess the impact of this factor, the structural change index:

The last in this system is fixed price index which ignores the structure change:

There is a relationship between the indices:

Example 11. There is data on the sale of goods A in the city's markets (Table 6.7).

Below are the conditions and solutions to the problems. Solution upload in format doc starts automatically after 10 seconds.

Objective 2.

For the enterprise, the plan for the reporting year provided for uve- increase in product release"A" by 10%, products "B" - by 8%, products "C" - by 5% compared to the previous year. Actual production from- item "A" in the reporting year was 1.2 times more, item "B" by 2%, item "C" 2 times more than in the previous year. Determine the indicators of the degree of fulfillment- neniya plan for the release of products "A", "B", "C".

Solution.

Let us determine the degree of plan fulfillment for each product by dividing the dynamics index by the plan target index.

For product A: 1.2 / 1.1 = 1.0909 or 109.09%.

For product B: 1.02 / 1.08 = 0.9444 or 94.44%.

For product B: 2 / 1.05 = 1.9048 or 190.48%.

In the reporting period, compared to the baseline period, the plan for the manufacture of items A was overfulfilled by 9.09%, - items B were underfulfilled by 5.56%, - items C were overfulfilled by 90.48%.

Task 6.

The following data is available on commission trade turnover

Product group	Trade turnover, billion rubles		Changes in prices in the II quarter. in comparison with the 1st quarter,%
Product group	I quarter.	II quarter.
Vegetables	15,4	40,2
Meat	24,5	18,5
Milk	10,4	14,5

Based on these data, calculate: 1) the general price index; 2) the general index of turnover in actual prices; 3) the general index of turnover is not- change prices; 4) changes in household expenditures as a result of price changes.

Solution.

Product

Average annual price, rub.

Product

Milk, thousand liters

Potatoes, t.

Eggs, tens of thousands

V the reporting period compared to the base period, the turnover increased by 45.5%.

D In order to calculate the general price index, we introduce the formula:

= we get the average harmonic index.

- individual price index. In the problem statement, we are given a change in prices for each product:

for vegetables - = 1.12; for meat - = 1.1; for milk - = 1.1.

AND The price index is calculated using the harmonic average index:= or 111.1%

WITH let's leave equality:

where or 131%

In the reporting period, compared with the base period, the turnover in constant prices increased by31%. Due to the change in prices, the increase in trade turnover amounted to 11.1%.

Let's define the increase in the costs of the population caused by the rise in prices:

73.2 - 65.893 = 7.307 billion rubles.

A absolute increase in turnoverin the reporting period compared to the base perioddue to price changesamounted to 7.307 billion rubles.

Task 7.

For the base and reporting periods, the enterprise produced products worth 20 and 22 billion rubles, respectively. (at current prices). Into the report- In the same period, prices for products were increased by an average of 15%. Define- pouring: a) change in the physical volume of products; b) change in the cost of products (in absolute terms) due to changes in the physical volume of products and changes in prices.

Solution.

Let's define the index of the cost of production:

I pq = p 1 q 1 / p 0 q 0 = 22/20 = 1.1.

Volume index of products:

I q = I pq / I p = 1.1 / 1.15 = 0.9565.

Where I p - product price index, I q - index of the physical volume of production.

The absolute change in the cost of production:

∆ pq = p 1 q 1 - p 0 q 0 = 2 2 - 2 0 = 2 billion rubles.

In the reporting period compared to the base period, there was cost products by 10% or - by 2billion rubles (in absolute terms).

Absolute change in value due to changes in the physical volume of products:

∆ pq (q) = p 0 q 0 ∙ (I q - 1) = 20 ∙ (0.9 565 -1) = - 0.87 billion rubles.
