What is the Laspeyres price index formula?
The Laspeyres Index is calculated by working out the cost of a group of commodities at current prices, dividing this by the cost of the same group of commodities at base period prices, and then multiplying by 100. This means that the base period index number is always 100.

Why is Laspeyres calculating a price index often used?
Easy to calculate and commonly used. Cheap to construct. Quantities for future years do not need to be calculated – only base year quantities (weightings) are used. Presents a meaningful comparison, as changes in the index are attributable to the changes in price.

Why Laspeyres and Paasche price indices are different?
A Laspeyres quantity index values the quantities at the fixed prices of the earlier period, while the Paasche quantity index uses the prices of the later period. The ratio of the values of the expenditures in two periods (V) reflects the combined effects of both price and quantity changes.

The Laspeyres Price Index is a consumer price index used to measure the change in the prices of a basket of goods and services relative to a specified base period weighting. Developed by German economist Etienne Laspeyres, the Laspeyres Price Index is also called the base year quantity weighted method.
What does the rise in the price level signify?
The rise in the price level signifies that the currency in a given economy loses purchasing power (i.e., less can be bought with the same amount of money). . The index commonly uses a base year figure of 100, with periods of higher price levels shown by an index greater than 100 and periods of lower price levels by indexes lower than 100.
What are the disadvantages of the Laspeyres index?
The main disadvantage of the Laspeyres index is that it is upward biased. This means that it overestimates inflation. There are three reasons why this is the case:
