Do you think TRADE AGREEMENTS will be a help in the negative merchandize balance in the Philippines?

Answer 1

First question should be: is a negative trade balance really a problem for the economy?

2nd question:
What is the cause of this trade deficit?

3rd question:
Do the trade agreements address the causes of the deficit?

I'm not knowledgable enough regarding the Philippines to answer those questions, so I won't attempt your question. That said, having a more open economy has been repeatedly shown to increase GDP. Look at Spain when it joined the EU or Chile and their trade agreements with the US. These types of agreements tend to be good for economies if they are broad in scope. It is impossible to tell how exactly it will effect trade balances.
