Economics Essay Question

I believe, there was an essay question in economics in the last year exam. Those who took L3 last year, Can you recollect details on that essay question, pls. - what topic it was related to, how big the essay was, did it need calculations, etc.

Isn’t the essay section of last year’s exam on the CFA website?

Yes it was question 10 in the morning exam and covered Grinold Kroner model and other aspects, like components of operating profit margin ie impact of unit labor cost, capacity utilisation etc on op margin.
