Starting sentence with "indeed" to complete previous statement

Is it correct to add a sentence that starts with indeed in order to complete a previous statement? For example,

The political crisis has a negative influence on the economy. Indeed, foreign investments have never been as low.

Is it recommended to start a sentence with indeed in a research paper?

Solution 1:

Is this sentence grammatically correct?

Yes, the sentence is OK. The meaning is something like this:

The political crisis has a negative influence on the economy. You can see that this is true, because, for example, foreign investments have never been as low.

Is it recommended to start a sentence with "indeed" in a research paper?

I don't think "recommended" is the right choice of words—that makes it sound like you should use it whether or not it is called for—but it should be acceptable.

Solution 2:

Indeed you can. :-)
