In the world of finance, comparison of economic data is of immense importance in order to ascertain the growth and performance of a compan. Description: Institutional investment is defined to be the investment done by institutions or organizations such as banks, insurance companies, mutual fund houses, etc in the financial or real assets of a country.

Simply state. Marginal standing facility MSF is a window for banks to borrow from the Reserve Bank of India in an emergency situation when inter-bank liquidity dries up completely. Description: Banks borrow from the central bank by pledging government securities at a rate higher than the repo rate under liquidity adjustment facility or LAF in short.

The MSF rate is pegged basis points or a percentage. Description: If the prices of goods and services do not include the cost of negative externalities or the cost of harmful effects they have on the environment, people might misuse them and use them in large quantities without thinking about their ill effects on the env.

When drafting a contract that uses an index series for escalation, it is helpful to be as specific as possible so that all parties will be clear about the terms. By using seasonally adjusted data, some users find it easier to see the underlying trend in short-term price changes.

It is often difficult to tell from raw unadjusted statistics whether developments between any 2 months reflect changing economic conditions or only normal seasonal patterns. Therefore, many economic time series, including the CPI, are adjusted to remove the effect of seasonal influences—those which occur at the same time and in about the same magnitude every year.

Among these influences are price movements resulting from changing weather conditions, production cycles, changeovers of models, and holidays. Seasonally adjusted indexes that have been published earlier are subject to revision for up to 5 years after their original release. Therefore, unadjusted data are more appropriate for escalation purposes.

National or U. For the CPI-U, an extensive set of component indexes and sub-aggregates are published monthly along with the all items index. A similar, but slightly smaller set is published for the CPI-W. For the C-CPI-U, only national indexes are published, with a more limited set of components and aggregates published. The set of components and sub-aggregates published for regional and metropolitan indexes is more limited that at the U. Each local index has a much smaller sample size than the national or regional indexes and is, therefore, subject to substantially more sampling and other measurement error.

As a result, local-area indexes are more volatile than the national or regional indexes, and we urge users to consider adopting the national or regional CPIs for use in escalator clauses.

Used with caution, local-area CPI data can illustrate and explain the impact of local economic conditions on consumers' experience with price change. If there is no CPI for the area you are in, we can provide some guidance on a recommended area to use instead, but users must make the final decision.

No, an individual area index measures how much prices have changed over a specific period in that particular area; it does not show whether prices or living costs are higher or lower in that area relative to another. In general, the composition of the market basket and the relative prices of goods and services in the market basket during the expenditure base period vary substantially across areas.

One limitation is that the CPI may not be applicable to all population groups. The CPI does not produce official estimates for the rate of inflation experienced by subgroups of the population, such as the elderly or the poor. Note that we do produce an experimental index for the elderly population that is available upon request; however, because of the significant limitations of this experimental index, it should be interpreted with caution.

Another limitation is that the CPI cannot be used to measure differences in price levels or living costs between one area and another as it measures only time-to-time changes in each area. A higher index for one area does not necessarily mean that prices are higher there than in another area with a lower index.

Instead, it means that prices have risen faster in the area with the higher index calculated from the two areas' common reference period. Additionally, the CPI is a conditional cost-of-living measure; it does not attempt to measure everything that affects living standards. Factors such as social and environmental changes and changes in income taxes are beyond the definitional scope of the index and are excluded.

Limitations in measurement can be grouped into two basic types, sampling error and non-sampling error. Sampling error. Because the CPI measures price changes based on a sample of items, the published indexes differ somewhat from what the results would be if actual records of all retail purchases by everyone in the index population could be used to compile the index.

These estimating or sampling errors are limitations on the accuracy of the index, not mistakes in calculating the index. The CPI program has developed measurements of sampling error, called variance estimates, which are updated and published annually at CPI Variance Estimates.

The CPI sample design allocates the sample in a way that maximizes the accuracy of the index, given the funds available. Non-sampling error. These errors occur from a variety of sources and unlike sampling errors, they can cause persistent bias in measurements of the index. Non-sampling errors are caused by problems of price data collection, logistical lags in conducting surveys, difficulties in defining basic concepts and their operational implementation, and difficulties in handling the problems of quality change.

Non-sampling errors can be far more hazardous to the accuracy of a price index than sampling errors so we expend considerable effort to minimize these errors. Highly trained personnel ensure the comparability of quality of items from period to period; collection procedures are extensively documented, and recurring audits are conducted.

The CPI program has an ongoing research and evaluation program in order to identify and implement improvements in the index. The CPI will need revisions as long as there are significant changes in consumer buying habits or shifts in population distribution or demographics. By developing annual Consumer Expenditure Surveys and Point-of-Purchase Surveys, the Bureau has the flexibility to monitor changing buying habits in a timely and cost-efficient manner.

In addition, the census conducted every 10 years by the U. Census Bureau provides information that enables us to reselect a new geographic sample that accurately reflects the current population distribution and other demographic factors. BLS is continually researching improved statistical methods, so even between major revisions, improvements are made to the CPI. Information on the CPI is available from our website and through email subscriptions to data products, and a variety of publications.

Information specialists are also available in the national and regional offices to provide assistance via email or telephone. BLS provides free access to published CPI data via press releases, tables, and current and historical data from our database.

Can indexes for individual areas be used to compare living costs among the areas? Note that the price data is collected periodically, and thus, the CPI is used to calculate the inflation levels in an economy.

This can be further used to compute the cost of living. This also provides insights as to how much a consumer can spend to be on par with the price change. The Reserve Bank of India and other statistical agencies study CPI so as to understand the price change of various commodities and keep a tab on inflation. Economists are in charge of collecting data by surveying households on their buying patterns, most purchased items, and daily expenses.

Who maintains Consumer Price Index in India? How is Consumer Price Index calculated? The CPI is calculated with reference to a base year, which is used as a benchmark. The price change pertains to that year. Remember, when you calculate the CPI, note that the price of the basket in 1 year has to be first divided by the price of the market basket of the base year.
