No. A bird in the hand is worth two in the bush. That sale you failed to make today might not be there tomorrow.
Does a shortage drive demand somewhat? Does it create a positive impression for your product? Yes, but it's not worth the risk to purposefully manipulate the market and it's an awfully short-sighted tactic. The upside is relatively minor and probably doesn't even make up for the downside--and that's without considering the logistics of screwing up your own supply chain.
