What’s a budget limit?

[ad_1]

The budget constraint is a concept from what is known as consumer theory in economics, which shows how a consumer’s spending ability is limited by their income or budget. For example, if a consumer only has to spend $100 US dollars (USD) and wants to buy a wine priced at $10 USD per bottle, then he can afford to buy only 10 bottles. As an economic tool, a budget constraint can be plotted on a graph, and is usually demonstrated using an example of a consumer with a specific budget dedicated to buying two products at certain prices. Such an example will show the many possible combinations of the two products that the consumer can afford to buy within his budget.

Essentially, the concept of a budget constraint demonstrates the relationship between income and purchasing power. To demonstrate this relationship, economists typically use a basic example of a consumer who has a specified amount of money and a choice between two goods, such as good A and good B. However, the consumer may choose to buy a combination of the good A and good B depending on your particular preferences and needs. Any combination is more or less achievable as long as you stay within budget. In practice, consumers buy more than just two goods, however the use of two goods in the example keeps things simple.

To illustrate, one might consider a consumer who has a budget of $1,000 per week to spend on good A and good B. Good A costs $5 and good B costs $20. At the extremes, the consumer can choose to spend all of his money on good A, which means that he could buy 200 units of good A per week. If he or she bought only good B, then 50 units would be purchased per week.

On a graph, good A and good B can be plotted on the Y axis and X axis, respectively. The Y axis is the vertical line and the X axis is the horizontal line on the graph. Using the example above, one point can be plotted on the Y axis at 200, denoted as point A, and another point can be plotted on the X axis at 50, denoted as point B. So what is called the budget constraint slope can be drawn diagonally from point A to point B, and will visually show all possible combinations of good A and good B as constrained by the $1,000 budget. The slope shows the maximum number of goods and services that can be purchased given a specific budget and specific prices.

In the graph, the slope of the budget constraint is calculated using the following formula: “growth over execution”. In other words, the “rise,” which is the change in the value of Y, is divided by the change in the value of X, also called the “run.” In the example above, the change in Y would be 200, and the change in X would be 50, so the slope would be 200/50, which is equal to 4.

There is also what is called an intertemporal budget constraint, which is the spending limit possible over a long time, depending on the resources available during that period. That is, the intertemporal budget limit is equal to the total income that a consumer earns or expects to earn in his lifetime, including any other assets he may have. This concept is also based on the fact that consumers make decisions about how to spend their money, and one of its purposes is to help them make the most of their resources, either in the present or in the future.

Theoretically, an intertemporal budget constraint can help all kinds of consumers choose to spend money now or at a later date in the future. For example, with this theory, they might do some calculations and think that they can postpone current consumption and invest their money. This approach can make them rich in the future, for example, and therefore increases their spending power, which means they could eventually earn more by growing their money first before spending it.
