Jim Hamilton has made available his paper “THE VIRGIN WILL CONCEIVE:
TYPOLOGY IN ISAIAH AND FULFILLMENT IN MATTHEW, THE USE OF ISAIAH 7:14 IN MATTHEW 1:18–23″ which will be published as a chapter in the forthcoming book Built upon the Rock which examines various biblical-theological nuances of Matthew. See his paper here (PDF).
He writes, “My objective in this essay is to argue for an understanding of Matthew’s use of Isaiah 7:14 which allows the text to mean what it says in its OT context.That is to say, I am not arguing against the virgin birth by saying that Isaiah was not predicting it. Matthew’s testimony to the virgin birth of Jesus is sufficient for it to be established. The question for this study is how Matthew understands and claims fulfillment for the OT.”
