“When ‘Free Trading’ Isn’t Really Free,” The Wall Street Journal, November 10, 2018 B5. You can avoid commissions when trading stock by using an app. But if the price you pay or get paid for the stock is more or less, is the trade really free? It depends on how much price improvement is involved.
Interesting study of how the benefits and cost savings on high frequency trading are divided among the various parties. And who knows what.
Isn’t this type of “information imbalance” inherent in every transaction? Do we know how much a tomato or an iPad costs the store that sells it? Or whether the salesperson gets a commission? How do we manage that imbalance? Or do we just accept it, whatever it means?
