Key Concepts

Wage Gap Analysis

This concept involves measuring the difference in average earnings between groups, such as men versus women or different racial groups. While a wage gap can indicate disparities, it does not by itself explain the underlying causes, necessitating a deeper analysis to determine if discrimination is a factor.

Causation vs. Correlation

Understanding the distinction between these two is crucial. A wage gap might correlate with group membership, but this does not necessarily mean that the gap is caused by employer discrimination. Other factors, not accounted for in the simple average, could be influencing the result.

Omitted Variable Bias

This concept refers to the error that occurs when relevant factors (e.g., experience, education, occupation type) that may account for variations in wages are left out of the analysis. Such omissions can lead to misleading conclusions about the presence or extent of discrimination.

Statistical Controls in Discrimination Studies

Implementing statistical controls is essential in isolating the effect of discrimination from other influencing factors. By accounting for differences in individual and job-related characteristics, researchers can more accurately determine whether observed wage gaps are attributable to discriminatory practices or other variables.

00:01 An earnings gap actually cannot be explained by discrimination, especially if there is no governmental discrimination.

00:13 In other words, if you look at a case like south africa where there was an apartheid for many, many years, in some cases in south africa, you could explain wage differentials by government controlled discrimination.

00:25 But in a free market situation, that's not the case.

00:29 If we just look at a few key components, there are many more, but if we just look at a few, this helps explain that.

00:36 For example, earnings tend to increase with age.

00:39 As you get more and more experienced, you become more and more valuable as an employee because you're more and more productive.

00:46 So we expect someone who's older to make more, for example, than a teenager on the minimum wage.

00:53 So if earnings go up with age, then that means that groups that are older are going to tend to make more money.

01:00 Well, the average age of a white person in america is higher than the average age of a black person.

01:08 Similarly, the average age of an asian in america is higher than the average age of whites.

01:14 So it's not uncommon then that asians as a group earn more than whites, and whites as a group earn more than blacks.

01:23 Another issue would be literacy rates, and i hope you all got the joke.

01:35 If you didn't, it's okay.

01:37 Keep trying.

01:38 So, for example, if one group has a higher literacy rate than another, you would expect the group with the higher literacy rate to get paid more.

01:49 Why? well, there are more jobs that require literacy than not.

01:56 Additionally, the jobs that get paid more money are all jobs...
