Opportunity profits vs. opportunity costs Having learned that 

Opportunity costs = the costs for avoided profits 

are a well established and quite useful economic concept, I wonder how its counterpart is officially called and investigated:

Opportunity profits = the profit by avoided costs

Costs can be avoided in many different ways: 


by paying unfair wages
by not providing good working conditions
by paying too low taxes
by exploiting the environment without paying for avoidance or reparation of damages and pollutions.




My question is for


the official name of "profit by avoiding costs"
some standard references on this topic
esp. in comparison with opportunity costs




A useful article on opportunity costs is this one:


  Do Economists Recognize an Opportunity Cost When They See One? 


One may as well ask: 


  Do Economists Recognize an Opportunity Profit When They See One?




Side question (the other way around): Would


paying higher wages than normal or necessary
providing better working conditions than normal or necessary
paying higher taxes than normal or necessary
paying more for avoidance and reparation of environmental damages and pollutions than normal or necessary


count as opportunity costs?
Opportunity cost is simply the value not obtained of the highest value alternative. It can be positive or negative; meaning it doesn't really make sense to define the opposite as opportunity profit. There is only two ways to go about it rationally, either you are profiting from doing something, or you are not profiting by not doing something, which is defined as opportunity cost. Opportunity profit would just equate to opportunity cost because you are not doing whatever the opportunity is. (Also, I'm not the down voter).
