Answer:
Decrease; More of good Y only and less good X.
Explanation:
So, if we are to solve this problem we will be looking at some explanations on some key words in the question above. I will be explaining two of the key words in the question and they are; autarky and world market.
When we say a country is in autarky we mean that the country does not require other countries in the ways they go about things especially trading in the country. A good example of a country in autarky is North Korea.
World market simply means the trading that has to do with international countries trading with one another.
So, as the PX/PY in the country A increases in autarky, as soon as they are in the world market and they meet another country, say country G which has lesser PX/PY than them, country A will have to export more of the product Y.
This will make the producers in country A to want to produce more of the the product or good Y and less of the product or good X.
