## Weighted index numbers economics

Index numbers. Economists frequently use index numbers when making comparisons over time. An index starts in a given year, the base year, at an index number of 100. In subsequent years, percentage increases push the index number above 100, and percentage decreases push the figure below 100. A trade weighted index is used to measure the effective value of an exchange rate against a basket of currencies. The importance of other currencies depends on the percentage of trade done with that country. For example in calculating the trade weighted index of the Pound Sterling, the most important exchange rate would be with the Euro. Compute the weighted aggregative price index numbers for $$1981$$ with $$1980$$ as the base year using (1) Laspeyre’s Index Number (2) Paashe’s Index Number (3) Fisher’s Ideal Index Number (4) Marshal-Edgeworth Index Number. The use of weighted index numbers in A-Level Economics is introduced and explained in this revision video. A weighted index is an ‘average’ index, made up of a combination of other indices - good The weighted geometric mean of relatives is computed in the same manner as the unweighted geometric mean of relatives index number except that weights are introduced by applying them to the logarithms of the relatives. When this method is used the formula for computing the index is: and V = value weight, i.e., p0q0 for each item. Steps.

## The trade-weighted effective exchange rate index, a common form of the effective exchange The trade-weighted effective exchange rate index is an economic indicator for comparing the exchange rate of a country against Economic indicators · Index numbers · Foreign exchange market · Economics and finance stubs.

Index numbers are used as a barometer to indicate the changes in economic Paasche method, Fisher method and the fixed weight aggregates method. The index number that is computed after assigning due weightage to different items under study is called weighted index number. In such a case, weights are A quarterly index for example, may be a weighted average of the respective monthly indices or may be computed from quarterly aggregates of the monthly data The paper reviews four main approaches to bilateral index number theory where two of fixed baskets, stochastic, test or axiomatic and economic approaches. The use of weighted index numbers in A-Level Economics is introduced and explained in this revision video. A weighted index is an ‘average’ index, made up of a combination of other indices - good examples are the Human Development Index and the Consumer Prices Index. Weighted Index Numbers Unlike simple index numbers, weighted index numbers, as the name suggests, weigh items according to their importance with respect to the concerned variable. For example, when calculating the price index number if the price of a unit of rice is twice the price of a unit sugar then the rice will be weighed in as ‘2’ whereas sugar will be weighed in as ‘1’.

### Index numbers are used as a barometer to indicate the changes in economic Paasche method, Fisher method and the fixed weight aggregates method.

Economics Topics Weighted Index Numbers. Group(s): Macro (Year 1) Key Terms, Macro (Year 2) Key Terms, Micro (Year 1) Key Terms, Micro (Year 2) Key Terms Similarly, weighted index number can be constructed either by (i) weighted aggregative method, or by (ii) weighted average of price relative’s method. The choice of method depends upon the availability of data, degree of accuracy required and the purpose of the study. What are index numbers? Index numbers are a useful way of expressing economic data time series and comparing / contrasting information. An index number is a figure reflecting price or quantity compared with a base value. The base value always has an index number of 100. The index number is then expressed as 100 times the ratio to the base value. Paasche’s Index Number In this index number the current (given) year quantities are used as weights, so it is also called the current year weighted index. Fisher’s Ideal Index Number The geometric mean of Laspeyre’s and Paasche’s index numbers is known as Fisher’s ideal index number.

In its Index number of prices with weights attached to different products is called weighted index number of prices. We allocate weights for different commodities. Then price indices for each good and for each year are multiplied by the appropriate or assigned weights and then average is obtained by dividing the total of these weighted indices by the total of the weights.

### In this index number the average of the base year and current year quantities are used as weights. This index number was proposed by two English economists,
