Inflation is the index of general growth of prices for goods and services

Financial measures. They include increased control of state expenses, private expenses, private and state investments. Tax regulations also belong here: the tax system must provide stimulation to those who save, invest, or produce more.

Price control. Another efficient measure of conquering inflation is increasing production and controlling prices for goods from the basic basket, such as food, clothes, fuel, etc.

Closing thoughts

Inflation levels show how high prices have grown for certain goods and services over s certain timeframe. To assess inflation, several indices are used (CPI, PPI, WPI). Moderate inflation enhances economic growth, while high inflation have a negative influence on the economy. Control over inflation is carried out by the Central Bank; the main controlling measure is toughening of credit and monetary policy.

To combat this, the monetary authority (in most cases, the central bank) takes the necessary steps to manage the money supply and credit to keep inflation within permissible limits and keep the economy running smoothly.
Theoretically, monetarism is a popular theory that explains the relationship between inflation and the money supply of an economy. For example, following the Spanish conquest of the Aztec and Inca empires, massive amounts of gold and especially silver flowed into the Spanish and other European economies. Since the money supply rapidly increased, the value of money fell, contributing to rapidly rising prices.
Inflation is measured in a variety of ways depending on the types of goods and services. It is the opposite of deflation, which indicates a general decline in prices when the inflation rate falls below 0%. Keep in mind that deflation shouldn't be confused with disinflation,which is a related term referring to a slowing down in the (positive) rate of inflation.

Causes of Inflation

An increase in the supply of money is the root of inflation, though this can play out through different mechanisms in the economy. A country's money supply can be increased by the monetary authorities by:

• 
  Printing and giving away more money to citizens
  
• 
  Legally devaluing (reducing the value of) the legal tender currency
  
• 
  Loaning new money into existence as reserve account credits through the banking system by purchasing government bonds from banks on the secondary market (the most common method)
  

In all of these cases, the money ends up losing its purchasing power. The mechanisms of how this drives inflation can be classified into three types: demand-pull inflation, cost-push inflation, and built-in inflation.

Demand-Pull Effect

Demand-pull inflation occurs when an increase in the supply of money and credit stimulates the overall demand for goods and services to increase more rapidly than the economy's production capacity. This increases demand and leads to price rises.
When people have more money, it leads to positive consumer sentiment. This, in turn, leads to higher spending, which pulls prices higher. It creates a demand-supply gap with higher demand and less flexible supply, which results in higher prices.

Cost-Push Effect

Cost-push inflation is a result of the increase in prices working through the production process inputs. When additions to the supply of money and credit are channeled into a commodity or other asset markets, costs for all kinds of intermediate goods rise. This is especially evident when there's a negative economic shock to the supply of key commodities.
These developments lead to higher costs for the finished product or service and work their way into rising consumer prices. For instance, when the money supply is expanded, it creates a speculative boom in oil prices. This means that the cost of energy can rise and contribute to rising consumer prices, which is reflected in various measures of inflation.

Built-in Inflation

Built-in inflation is related to adaptive expectations or the idea that people expect current inflation rates to continue in the future. As the price of goods and services rises, people may expect a continuous rise in the future at a similar rate. As such, workers may demand more costs or wages to maintain their standard of living. Their increased wages result in a higher cost of goods and services, and this wage-price spiral continues as one factor induces the other and vice-versa.
