Belarus has an upper-middle-income mixed economy, with a focus on centralised political and economic controls by the state. The country's economy is heavily reliant on key industries such as manufacturing, agriculture, and the service sector, which includes information technology. Understanding the concept of elasticity is crucial for Belarus's economy, as it helps determine how changes in price, income, or other factors influence the demand for and supply of goods and services.
Elasticity measures the responsiveness of one economic variable to changes in another. For example, if the price of a product increases, how will the quantity demanded by consumers change? This concept is essential for businesses and the government in making strategic decisions, such as pricing, taxation, and intervention policies.
The recent political events, including the 2020 presidential election and the country's role in the Russia-Ukraine conflict, have had significant impacts on foreign investment and trade in Belarus. These events, along with economic sanctions, have created an unpredictable economic situation in the country. Understanding elasticity is vital for navigating these challenges and making informed decisions to promote economic growth and stability in Belarus.
What You'll Learn
Price elasticity of demand
The economy of Belarus is a post-Soviet transition economy, described as an upper-middle-income mixed economy. The Belarusian government has retained centralised political and economic controls, emphasising full employment and a dominant public sector.
Types of Price Elasticity of Demand
Perfectly Inelastic Demand
If a product's price elasticity is 0, it is considered perfectly inelastic, meaning demand remains the same regardless of price changes. These are usually essential items or services.
Relatively Inelastic Demand
If the percentage change in demand is less than the percentage change in the product's price, it is considered to have relatively inelastic demand. These are often necessary goods or services that people are willing to pay more for, such as electricity.
Unit Elastic Demand
If a price increase of X% leads to an X% decrease in demand, the product has unit elastic demand. However, this is a hypothetical concept, as demand is never completely linear.
Relatively Elastic Demand
If a small change in price leads to a large change in demand, the product has relatively elastic demand. This is usually associated with items that have several substitutes.
Perfectly Elastic Demand
If demand falls to zero at the slightest price increase, or becomes great with a slight price decrease, the product has perfectly elastic demand. However, this is also a hypothetical concept, as demand is never linear enough to prompt an absolute drop in demand.
Calculating Price Elasticity of Demand
The formula for calculating price elasticity of demand is:
> % Change in Quantity Demanded / % Change in Price = Price Elasticity of Demand
If the resulting value is greater than 1, the product is considered to be elastic. If the value is less than 1, it is considered inelastic.
Examples of Elastic and Inelastic Goods
Elastic goods include luxury items, airline tickets, fast food, OTT platforms, and furniture. Elasticity varies according to the availability of close substitutes, the relative cost of the good, and the time elapsed since the price change.
Inelastic goods include gasoline, tobacco, prescription drugs, and addictive products. These are often essentials or products with no good substitutes, so demand remains stable even when prices increase.
Importance of Price Elasticity of Demand
Understanding price elasticity of demand allows businesses to make informed decisions about pricing strategies. It also helps governments assess how to impose taxes on goods.

Income elasticity of demand
In Belarus, an upper-middle-income economy, the income elasticity of demand can vary across different products and services. For example, luxury items and certain food and beverage products are likely to have higher income elasticity of demand, as changes in consumer income can significantly impact their demand. On the other hand, essential goods and services, such as utilities, prescription drugs, and tobacco products, tend to have lower income elasticity of demand, as demand for these products remains relatively constant even when consumer income changes.
Understanding the income elasticity of demand is crucial for businesses operating in Belarus, as it can help them make informed decisions about pricing, production, and marketing strategies. Additionally, it can provide insights into consumer behaviour and preferences, which can be valuable for businesses looking to succeed in the Belarusian market.

Cross-price elasticity of demand
As a post-Soviet transition economy, Belarus has a highly centralized economy with a dominant public sector. The country has maintained government control over key industries and rejected large-scale privatisation.
Elasticity is a term used in economics to describe the responsiveness of one variable to changes in another. In this case, we will focus on cross-price elasticity of demand, which measures the responsiveness in the quantity demanded of one good when the price of another good changes. This concept is particularly useful for businesses when determining and setting the prices of their goods and services.
The formula for calculating cross-price elasticity of demand is:

Elasticity of intertemporal substitution
As an upper-middle-income mixed economy, Belarus has a highly centralised economy that emphasises full employment and a dominant public sector. The Belarusian economy is the 74th largest in the world by GDP and has been described as a welfare state or market socialist.
The elasticity of intertemporal substitution (EIS) is a measure of how responsive the growth rate of consumption is to the real interest rate. In other words, it measures a consumer's willingness to substitute future consumption for present consumption.
Mathematically, the EIS is defined as:
! [ {\displaystyle \sigma (c)=-{\frac {u'(c)}{cu''(c)}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/90549403046345154800626343512674106281)
Where:
- C denotes the consumption level
- U(c) is the utility function
The EIS can be defined in two ways:
- Abstractly as a function derived from the utility function, then interpreted as an elasticity
- Explicitly derived as an elasticity
The elasticity of intertemporal substitution plays a crucial role in the theory of consumption and saving, particularly in the life-cycle version of that theory. It helps determine the speed of adjustment to the steady state and the behaviour of the saving rate during the transition.
For instance, if the elasticity is high, consumers will save a large portion of their income when the real interest rate is high. On the other hand, if the elasticity is low, consumers will save less and consume more when the real interest rate is high.
Empirical estimates of the elasticity of intertemporal substitution vary, with a mean elasticity of 0.5 reported across 169 published studies. Part of the challenge in estimating this elasticity arises from the difference in conclusions between microeconomic and macroeconomic studies.
In the context of Belarus, a study on the labour supply of Belarusian small entrepreneurs tested the intertemporal substitution hypothesis (ISH), which predicts a positive relationship between hours worked and transitory changes in wages. The results indicated that Belarusian entrepreneurs were willing to work a fixed number of hours regardless of their businesses' performance. Additionally, the study found that female entrepreneurs had a larger labour supply elasticity than males.

Price elasticity of supply
Belarus has an upper-middle-income mixed economy, with a focus on centralised political and economic controls by the state. The country's economy is the 74th largest in the world by GDP and has been described as a welfare state or market socialist.
The concept of elasticity is important in economics, and it refers to how responsive one variable is to changes in another. In the context of Belarus, elasticity can be applied to various aspects of its economy, including the supply of goods and services.
For example, Belarus has a significant agricultural sector, with potatoes, flax, hemp, sugar beets, rye, oats, and wheat as its chief agricultural products. The supply of these agricultural products can be affected by factors such as the availability of substitute products, the importance of these products to consumers, and the ratio of incomings. For instance, research on the demand and supply elasticity of agricultural products in Belarus from 2000 to 2005 found a low level of elasticity for potatoes, milk, pork, and beef. This means that changes in the price of these products did not significantly impact the quantity supplied. The low elasticity was attributed to factors such as the quantity of substitute products, the variety of usage possibilities, and the importance of these products to consumers.
Additionally, the Belarusian government has maintained control over key industries and rejected large-scale privatisations. This level of state involvement can impact the price elasticity of supply by influencing the responsiveness of producers to price changes. The state's role in setting prices and controlling industries may reduce the flexibility of suppliers to adjust their output levels based on market prices.
Moreover, Belarus has a highly regulated labour market, which can also impact the price elasticity of supply. The government influences wage determination, and the private sector has limited autonomy. This regulated labour market may affect the ability of firms to adjust their supply levels based on price changes, as labour is a critical factor in the production process.
In summary, the price elasticity of supply in Belarus is influenced by various factors, including the structure of its agricultural sector, the role of the state in the economy, and the regulated labour market. These factors can impact the responsiveness of suppliers to price changes, affecting the quantity of goods and services supplied in the Belarusian economy.

Frequently asked questions
Elasticity in economics describes how responsive one variable is to changes in another. For instance, how demand for a product changes as its price increases or decreases. Elasticity is an important measure for sellers as it reflects how much of a good or service consumers will buy when the price changes.
Elastic goods in Belarus would include luxury items and certain food and beverages, as price changes can significantly impact their demand. On the other hand, tobacco and prescription drugs are examples of inelastic goods, as demand often remains constant despite price fluctuations.
Understanding elasticity is crucial for governments when considering taxation. For instance, when increasing taxes on goods, elasticity can predict whether this will lead to a significant reduction in demand. Belarus, for instance, has imposed taxes on luxury goods, as these are more elastic and consumers may reduce their consumption in response to price increases.
