Some of the gains from trade shift to Portugal.

Explanation:

The law of comparative advantage describes how agents produces more of and consumes less of a good for which they have a comparative advantage in. Agents have a comparative advantage if they produce a good at a lower marginal cost prior to trade. Contrary to it, agent has an absolute advantage if they produce a good more productively, or more quantity of goods for a less amount of resources.

In this example, if the price of doormat increases to 5 hats per doormat, Spain will have to produce hats to get 1 doormat. Contrary to it, Portugal will get more hats for producing the same amount of doormats as before.

So, to conclude, Portugal will gain from this trade.
