Key Concepts

Technological Change

Technological change refers to innovations and improvements in production processes that enhance productivity and efficiency in the economy. By enabling faster production, better quality products, and more efficient resource allocation, technological progress plays a vital role in boosting both total output and labor productivity.

Economic Growth

Economic growth involves the increase in a country’s total production of goods and services over time. It is driven by factors such as technological advancements, improvements in labor and capital efficiency, and increased productivity, all of which contribute to both higher total output and output per worker.

Living Standards

Living standards encompass the quality of life and economic well-being of individuals in an economy. Improvements in total output and productivity generally lead to higher incomes, better access to goods and services, and overall enhancements in welfare, thereby directly affecting the everyday lives of typical people.

Total Output

Total output refers to the aggregate value of goods and services produced within an economy, typically measured by gross domestic product (GDP). It reflects the overall economic activity and provides a broad indicator of an economy’s size, health, and its capacity to generate wealth over time.

Output per Worker (Productivity)

Output per worker, or labor productivity, measures the average amount of goods and services produced by each worker. Increases in productivity indicate that workers are able to produce more output per unit of labor, often due to improvements in technology, skills, and capital, and are essential for understanding economic performance and growth.

00:04 Let's talk about income inequality in the u .s., and specifically since the 1970s.

00:30 And this might be a specific time of interest because it was relatively stable before then.

00:48 And so since we went to discuss income inequality and how it's changed, we're kind of interested in how do we calculate it.

01:16 And to do this, we look at quintiles of earnings.

01:37 And furthermore, we can depict this quintiles of earnings in a graph that we call a lorentz curve.

02:01 So to look at income inequality quintiles, we would take everyone in the country and look at their income and order and group them by lowest to highest.

02:48 And quintiles means we split it up in two -fifths.

02:51 If it was quartiles, it would be fourths.

02:56 And so we order it in the 20th, 40th, 60th, 80th, and then finally the 100th percentiles.

03:13 And basically, this can tell us how equal the distribution is of income by quintile.

03:21 And we want to see if there's a big difference between the lowest earners, and the highest earners to tell what's the level of income and equality.

03:36 And the way we show this is once again by the lorentz curve or how we can see it clearly.

03:45 So i'll start graphing the lorenz curve here.

04:01 On the x axis, we have the quintiles of earnings, which, as we saw, we're splitting up in two fifths...
