Final answer:
Productivity in the article is defined as the output per hour worked, which focuses on the value added by a worker to their employer's output, excluding government and farming sectors. Real GDP per person is the total economic output divided by the country's population.
Step-by-step explanation:
The article defines productivity as the amount of output per hour worked. This is a measure of worker productivity and represents the dollar value per hour each worker contributes to their employer's output. It's important to note that this measure typically excludes government workers and farming to focus on market-traded goods and services.
Real GDP per person is a measure that includes all of the goods and services produced in a country, representing the total economic output. It is often used to gauge the average economic output per person, which can then be used to draw comparisons between different countries or assess economic growth over time.
