Roger decided to build the deck himself

Explanation:

This example illustrates the need to work based on the laws of comparative advantage. Roger needed a deck, he could have paid someone to build it for him, but somehow he identified the need to build his deck himself as he believed it was more costly to employ or pay someone to build the deck for him.
