FAQ on Civil Aviation

Pallavi - October 22, 2012

According to a press release, the Ministry of Civil Aviation is considering abolishing the development fee being levied at the Delhi and Mumbai airports.  The Ministry has already asked the Kolkata and Chennai airports not to levy a development fee.  According to the Ministry, this is being done to make air travel more affordable.  Currently, development fee charged at the Delhi Airport ranges from Rs 200 to Rs 1300.  At the Mumbai airport, the fee ranges from Rs 100 to Rs 600. It is pertinent to note that though, the Ministry has proposed abolishing the development fee, the airport operators may still levy a user development fee.  In this blog we discuss some of the aspects of development fee and user development fee. What is a development fee and a user development fee? Development Fee (DF) is primarily intended to fund the establishment or upgradation of an airport.  It is intended to bridge the gap between the cost of the project and the finance available with the airport operator.  Currently only the Mumbai and Delhi Airports levy a DF. However, there are other types of tariffs, such as a user development fee (UDF), which may be levied by the airports. UDF is generally regarded as a revenue enhancing measure.  It is levied by the airport operators to meet operational expenditure Section 22 A of the Airports Authority Act, 1994 (amended in 2003) gives the Airport Authority of India (AAI) the power to levy and collect a development fee on embarking passengers.  The Act provides that the development fee can be utilised only for: (a) funding or financing the upgradation of the airport; (b) establishing a new airport in lieu of the airport at which is levied; and (c) investing in shares of a private airport in lieu of an existing airport . Unlike DF,  UDF is not levied and collected under the Airport Authority of India Act but under Rule 89 of the Aircraft Rules, 1937. Under the Aircraft Rules, UDF may be levied and collected by either the AAI or the private operator.   According to the Airport Economic Regulatory Authority, UDF is levied to ensure that the airport operators can get a fair return on their investments. What is the role of the Airport Economic Regulatory Authority? In 2008, the Airport Economic Regulatory Authority (AERA) was established to regulate aeronautical tariffs.  Among others, AERA’s functions include determining the amount of DF and UDF for major airports.  In case of non-major airports, the UDF shall be determined by the central government. What has been the role of the Supreme Court? In 2009, the central government permitted the Mumbai and Delhi Airports to levy a DF.  The rate of was prescribed by the central government and not by AERA.  In 2011, the Supreme Court held that this levy of DF was illegal.  The Court based its decision on two grounds. Firstly, the court held that the rate of DF has to be determined by the AERA and not the central government.  Secondly, the Court held that the power to levy the fee lies with the Airport Authority as the development fee can only be utilised for the performance of the purpose specified in the Act.  The court held that while the Airport Authority can utilise the development fee for any of the functions prescribed in the Act, it can assign the power to levy a development fee to a private operator only for funding or financing the upgradation or expansion of the airport. Can private operators collect a development fee and a user development fee? In 2003, the government amended the Airport Authority of India Act to allow the AAI with the prior permission of the central government to: (i) to lease the premises of airports to private entities to undertake some of the functions of the AAI; (ii) levy and collect a development fee on the embarking passengers at a rate that may be prescribed. Till 2011, the power to collect the development fee lay only with the Airport Authority.  However with the notification of the Airports Authority of India (Major Airports) Development Fees Rules, 2011, private operators have also been permitted to collect the development fee.  

The Monetary Policy Committee (MPC) has decided to conduct an off-cycle meeting today to discuss the failure to meet the inflation target under Section 45ZN of the Reserve Bank of India Act, 1934. As per the Reserve Bank of India Act (RBI), 1934, MPC is required to meet at least four times each year, to discuss the macroeconomic issues in the country, and take policy decisions to address those. This is the second time MPC has conducted an off-cycle meeting in 2022-23. The meeting is scheduled in light of inflation being consistently high for nine consecutive months.

In this blog, we discuss what the inflation targeting framework is, examine retail and wholesale prices, and the divergence between them.   

What is the inflation targeting framework, and what happens if inflation is persistently high?

In 2016, Parliament amended the RBI Act, 1934 to change the monetary policy, and introduce an inflation targeting framework. This framework prioritises price stability to achieve sustainable GDP growth. Price stability allows investors to confidently invest their money for productive activities, without worrying about it losing value. Price stability also maintains the purchasing power of consumers, i.e., the ability to purchase a good (or service) with a given amount of money.

As per the new framework, the central government, in consultation with RBI sets: (i) an inflation target, and (ii) an upper and lower tolerance level for retail inflation. The target has been set at 4%, with an upper tolerance limit of 6% and a lower tolerance limit of 2%. The upper and lower limits indicate that although it is desirable for inflation to be close to 4%, deviation between these limits is acceptable. The target and bands are revised every five years. In March 2021, the existing targets were carried forward.  

Retail inflation has been above 6% for the past nine months, and it has been above 4% from October 2019 onwards (See Figure 1).

If inflation is above or below the prescribed limits for three quarters, RBI must submit a report to the central government explaining why prices have been rising (or falling) persistently, what will be done to correct that, and an estimate as to when the target will be achieved.   

The MPC uses tools such as interest rates to control the level of inflation in the economy. One such rate is the policy repo rate, which is the rate at which RBI lends money to banks. An increase in the policy repo rate makes borrowing money more costly, and hence is expected to control inflation by reducing the money supply. MPC increased this rate from 4% in April 2022 to 4.4% in May 2022, to 4.9% in June 2022, to 5.4% in August 2022, and to 5.9% in September 2022.

Breaking down the Consumer Price Index and the Wholesale Price Index

Consumer Price Index (CPI) measures the general prices of goods and services such as food, clothing, and fuel over time. Retail inflation is calculated as the change in the CPI over a period of time. Goods and services such as petrol, food products, health, and education are considered for its calculation, which are assigned different weights (See Table 1). Between February 2022 and August 2022, the average annual inflation was 6.9%. The rise in prices of subcomponents of the CPI during this period is indicated in Table 2.

CPI is not the only index that measures inflation in an economy. The Wholesale Price Index (WPI) measures the wholesale prices of goods. A change in wholesale prices reflects wholesale inflation. Table 3 indicates the weights assigned to goods for calculating the WPI. Manufactured goods include metals, chemicals, food products, and textiles.   

Primary articles (23%) include food articles, and crude petroleum and natural gas. Fuel and power (12%) include mineral oils, electricity, and coal.  WPI has remained above 10% from April 2021 onwards. It reached an all-time high of 17% in May 2022. This was driven by the inflation in metals, kerosene and petroleum coke, fruits and vegetables, and palm oil.

Why has WPI inflation been consistently above CPI inflation?

Movements in the WPI have an impact on the CPI.  For almost a year and half, CPI inflation has remained below WPI inflation.  However, as per the design of the indices, it is expected that CPI would remain above WPI, and that any increase in WPI would reflect in the CPI after a time lag.  This is because retail prices include taxes (as a percentage of price), while wholesale prices do not.  Additionally, some of the goods in WPI act as inputs in the goods considered in CPI.  An increase in input prices would lead to higher retail prices after a time lag.

We discuss possible reasons for why CPI has remained below WPI for a year and a half.

Composition of indices

As indicated in Table 2 and 3, the composition of the two indices varies. For instance, prices of manufacture of basic metals, chemicals, and machinery grew at an average rate of 13% between February 2021 and September 2022.  They contribute 7% to the WPI. These are input goods for producing final goods and services such as automobiles, which are included in the CPI. The rise in prices of transport vehicles, communication devices, fuel for transport, and housing (CPI components) rose by 6% during this period.

The Ministry of Finance has observed that wholesale prices did not feed into retail prices (from March 2021 onwards) as wholesalers absorbed the rising input costs and did not pass them on to retailers. In August 2022, it noted that as retail prices are rising now, the pass-through may occur.
