What is Direct Relationship? definition and meaning

what is a direct relationship in economics

Microeconomics Direct relationship - increase leads to increased supply Direct relationship - subsidies effectually reduce the production. There is a direct or positive relationship between income and consumption spending. When there is a direct relationship between two variables the line is. In an inverse relationship, as x increases the absolute value of y decreases, in a direct equation, as x increases the absolute value of y also increases. Direct.

As one increases, the other decreases and vice versa. Direct Variation Consider the case of someone who is paid an hourly wage. The amount of pay varies with the number of hours worked.

This is an important component of direct variation: When one variable is 0, the other must be 0 as well. So, if two variables vary directly and one variable is multiplied by a constant, then the other variable is also multiplied by the same constant. If one variable doubles, the other doubles; if one triples, the other triples; if one is cut in half, so is the other. In the preceding example, the equation is y 12x, with x representing the number of hours worked, y representing the pay, and 12 representing the hourly rate, the constant of proportionality.

Graphically, the relationship between two variables that vary directly is represented by a ray that begins at the point 0, 0 and extends into the first quadrant. In other words, the relationship is linear, considering only positive values. See part a of the figure on the next page.

Variation, Direct and Inverse

The slope of the ray depends on the value of k, the constant of proportionality. The bigger k is, the steeper the graph, and vice versa. Inverse Variation When two variables vary inversely, one increases as the other decreases. As one variable is multiplied by a given factor, the other variable is divided by that factor, which is, of course, equivalent to being multiplied by the reciprocal the multiplicative inverse of the factor.

For example, if one variable doubles, the other is divided by two multiplied by one-half ; if one triples, the other is divided by three multiplied by one-third ; if one is multiplied by two-thirds, the other is divided by two-thirds multiplied by three-halves.

Consider a situation in which miles are traveled. If traveling at an average rate of 5 miles per hour mphthe trip takes 20 hours. If the average rate is doubled to 10 mph, then the trip time is halved to 10 hours. If the rate is doubled again, to 20 mph, the trip time is again halved, this time to 5 hours.

This creates an indirect relationship. Inverse relationship An inverse relationship, negative correlation, or inverse correlation is a contrary relationship between two variables. In other words, the two variables move in opposite directions.

For example, if Group 1 moves up, Group 2 subsequently declines, and vice-versa. Whether there is another variable in the situation is irrelevant. In other words, inverse relationships may be either indirect or direct relationships. There may be three or just two variables present.

It reported last week that the sales of diet products had increased. At the same time, sales of candy and chocolate had declined. Sometimes, it happened the other way round. Interest rates and the inflation rate have an inverse relationship.

In this context, interest rate refers to the rate at which the central bank lends to financial institutions. Inflation occurs when overall prices in an economy rise. Indirect relationship All this means is that one variable affects the another but through a third variable. They do not affect each other directly. However, Group A does not affect Group C directly.
