I have a measure of capital account openness (ka), where 0 is open and 1 is closed. I'm trying to identify periods when countries opened up or closed. For this, I look at a standard deviation jump of ka (0.132) and check whether the three-year moving average of ka 2 years before the jump is more than 0.2 higher/lower than the-three year moving average starting from one year after the jump. When it is lower, it classifies as a period of liberalization, when it is higher it would be a restriction of the capital account.
I want to create two indicators, caplib and capclose, where the three years making up the three year moving average are coded 1 if it is below/above the 0.2 threshold and 0 otherwise. This process should stop when the moving average drops below the threshold again, after which can be checked for new jumps and new period of liberalization/restriction. Perhaps this is best explained with a data example:
