1. How has technology (A) grown in South Korea (KR) and China (CN) over time? Use the US, KR, and CN technology (A) variables from the data table above to construct a graph from 1954 to 2019 using LINE 1, LINE 2, and LINE 3.Format the graph to convert the variables to have log scales. NOTES: With log scales, the slope of a variable reflects its growth rate over time. The technology variable is an index where 2017=100 for all countries. This does not mean the level of technology is the same in all countries, but the slopes in the variables from the 1950s to 2010s reflect different growth rates.

QUESTIONS: Compare and contrast US, KR, and CN technology over the entire time period. What are the similarities and differences? In the textbook and class lectures, we learned that South Korea (KR) is an example of the "catch-up effect" in macroeconomic growth. How does the graph show this effect for Korea relative to the US and China?Technology growth in China is very different before and after 1980. What is the main difference and how might it be related to the fact that China's foreign trade (exports and imports) increased dramatically after 1980?
