Identify which country appears to experience the highest level of youth unemployment over the sample period, and using a scatterplot, comment on whether youth unemployment appears to move together with labour productivity over time.

To identify the country with the highest level of youth unemployment ($YU_{it}$) over the sample period (2005-2024), you would typically calculate the average or median youth unemployment rate for each of the six countries (South Africa, Canada, Switzerland, the United States, Portugal, and the United Kingdom). Then, compare these summary statistics to find the country with the highest value. Without access to the specific dataset, a definitive country cannot be named.

To comment on whether youth unemployment ($YU_{it}$) appears to move together with labour productivity ($PROD_{it}$) over time, you would generate a scatterplot with youth unemployment on one axis (e.g., y-axis) and labour productivity on the other (e.g., x-axis).

• If the points on the scatterplot generally trend upwards from left to right, it suggests a positive relationship (they move together).
• If the points generally trend downwards from left to right, it suggests a negative relationship (they move inversely).
• If the points are scattered randomly with no clear pattern, it suggests no strong linear relationship. Without the actual scatterplot, a specific comment on the relationship cannot be made.
