Increasing octane raises the flashpoint and slows the burning process of gasoline If an engine does not have high enough compression to require higher octane there will be no improvement and it may in fact be harder to start and less effecient. Premium fuel is a waste in an engine that does not require it.
If you have the ability to tune your setup you will be able to run more ign with higher octane levels making for better performance and fuel economy if tuned correctly.
To make a blanket statement that more octane means less performance and fuel economy is ignorant. As stated above if you plan to only add additional octane with no adjustment to the tune then yes you "could" expect to see anywhere from gains, to no gains, to nothing noticeable. All of that depends on the motor setup.
