Quick takeaways
Inflation is measured by surveying a wide range of goods and services, averaging their prices over time, and tracking the average using the Consumer Price Index (CPI) which involves a comprehensive and complex data collection process.
The effectiveness of interest rate increases in combating inflation is uncertain, as the relationship between interest rates and inflation is complex, with expectations about future price levels also playing a crucial role in price setting behavior.

Measurement of Inflation
Inflation is measured by taking a survey of a wide variety of goods and services and their prices, averaging them, and tracking the average over time. The Consumer Price Index (CPI) in the United States, for example, is composed of the prices of 80,000 items, which are collected through a survey that involves tens of thousands of people. The prices are weighted based on the percentage of income spent by households on each item. This measurement process is a complex and large-scale effort to approximate the inflation rate.
Impact of Interest Rates on Inflation
There is ongoing debate about the effectiveness of interest rates in combatting inflation. While interest rate increases are intended to reduce aggregate demand and slow down the economy, the actual impact on inflation is uncertain. The European Central Bank (ECB) has a range of models that estimate the effects of interest rate increases on the European economy, but there is no consensus on which model is most accurate. The traditional understanding is that interest rate increases make borrowing more expensive, reduce investment, and lower aggregate demand, thereby reducing economic activity. However, the relationship between interest rates and inflation is complex, and expectations about future price levels also play a crucial role in price setting behavior. The current practical debate revolves around the effectiveness of interest rate increases and the need for central banks to act to show their commitment to addressing inflation.
Profit-Driven Price Increases
Recent inflationary pressures have been driven by profit-seeking and price-setting behavior in certain sectors. This is often referred to as 'greedflation,' although the term can be misleading. Rather than a continuous increase in prices driven by greed, what has been observed is more of a price shock resulting from price-setting tactics and the opportunity to raise prices. Sectors like food have experienced sharp price increases, often accompanied by increases in profit margins. Market concentration and monopolistic power have played a role in driving these price hikes. Efforts to address this type of inflation have involved direct price regulation, actions against monopolistic practices, and even geopolitical interventions aimed at reducing prices. Viewing inflation within the context of profit-driven price increases provides a different perspective on the causes and potential solutions.
Regional Differences in Inflation Rates
There is a notable East-West divide in inflation rates among EU member states. Eastern European countries have experienced higher inflation rates compared to their Western counterparts. Several factors contribute to this difference. First, there is a higher exposure to energy shocks among Eastern European countries due to their historical ties to the Soviet energy system. Second, lower per capita incomes in Eastern Europe result in a different inflation basket, with a greater weight on essential food items. Monopolistic power in the food sector has contributed to higher prices. Additionally, countries outside the Eurozone have greater flexibility in monetary and fiscal policy, allowing for variations in inflation rates. These factors combined contribute to the divergence in inflation rates between Eastern and Western Europe.
